Volunteering for Apollo in Poland

Posted By: Maureen 259 Views 0 Comment

This post is written by Maria Gezela and Karolina Baranowska and includes a report about their volunteering experience for LIFE Apollo2020 in Poland.

Honestly, not everyone knows what species monitoring is like. That is why we are going to tell you a little bit about it. First of all, we were volunteers for two weeks in the Apollo Volunteering Program that was created in collaboration with Karkonoski Park Narodowy and Klub Przyrodników.

We started our journey on the first of July and got to know everyone that had also participated in this program and read about the biology of Parnassius apollo. On the second day, we got to know Roman, Grzegorz and Dariusz from Karkonoski Park Narodowy and we learned a lot about Parnassius apollo from them. Firstly, we visited Karkonoski Bank Genów in Jagniątków, where there is Parnassius apollo rearing and we saw and got to know about the process.

Then we went to two quarries “Gruszka” and “Miłek” and we had a chance to release the imago form. It was the first time when we had held the butterflies in our hands. We all tried to be gentle with them, they were so beautiful and really special, not like any other butterfly. On the third day we got to know all the reintroduction sites, how they look, where Sedum maximum and nectar-producing plants are. There were eleven reintroduction sites such as: Chojnik, Podzamcze, Sobiesz, Wały Cieplickie, Piastów, Krzyż Jubileuszowy, Góra Szybowcowa, Kamieniołom “Gruszka”, Kamieniołom “Miłek”, Bobrów and Kruczy Kamień.

On Thursday, we all went to Kruczy Kamień and we finally got a chance to learn the transect and CMR methods. Also It was our first time catching butterflies and it was such an amazing experience, which we learned a lot from. Then we went to Karczma Sądowa in Uniemyśl, which is Klub Przyrodników field station. We had some coffee and talked a little bit, got to know the story behind the restoration of this place, because a few years ago it was completly ruined.

On friday, Jacek, Dominika and Ola were monitoring Parnassius apollo in Cieplice, Piastów, Sobiesz, Podzamcze and Chojnik. Karolina and I went to the Klimatyczne Karkonosze event and we colored wooden magnets, earrings and keychains that looked like Parnassius apollo with the children. Also, we educated them about our extraordinary butterfly.

On Saturday, we monitored Parnassius apollo in Kruczy Kamień and it was a huge success for us, we catched 15 individuals in which 5 were new (2 females with sphragis and 3 males). After Kruczy Kamień we went to Bobrów where something funny happened. We all decided to go around this small part of the forest, but we didn’t expect that we would have to climb back to get to our car. In the end we finally got to our car, but it was so tiring.  On Sunday, Jacek, Dominika and Ola went to Krzyż Jubileuszowy and Góra Szybowcowa. Karolina and I went to “Gruszka” and “Miłek” quarries. That day, the weather wasn’t good, so we saw nothing. Then we had to say goodbye to Ola and Dominik because they were going back home that day. That’s how our first week ended, we learned a lot about monitoring and honestly about everything from Roman, Grzegorz, Dariusz and Kamila. They helped us a lot and to be honest, they are not only great teachers but also funny and helpful.

The second week, we started with another monitoring session. Karolina  and I went to Chojnik, Wały Cieplickie and Piastów. Jacek went to Sobiesz and Podzamcze. Despite the beautiful weather, we couldn’t find any butterflies in Wały Cieplickie, Piastów, Sobiesz and Podzamcze. Just as we needed to end the monitoring, I found one dead Parnassius apollo… right beside me. It was a female with sphragis and she had a number 298 on her wings. 

Of course, our day couldn’t end without some adventure. On the way back from Chojnik to our car, we found sheep in trouble. The sheep was tangled in an electric fence, which we had to turn off and free her from. We also met new volunteers – Ola, Łucja and Magda. We went for monitoring until Wednesday with the interns – Julia and Justyna. For a moment we felt like teachers, because we tried to tell them everything about the butterfly, his biology, monitoring etc.

Thursday and Friday were days off for me and Karolina. On those days, we were able to rest and relax. Beside me, because I needed to defend my bachelor’s degree and I had a lot of problems on my way back to Jelenia Góra, because there was a problem with all trains to and from Wrocław. Luckily, my mum came to rescue me and drove me back to Jelenia Góra.

On Thursday, we also had the opportunity to learn a few things while catching bats. It was a great experience and we all had a lot of fun. On friday, Karolina and I went hiking. We did 16 km and also we were really lucky to see the blackgrouse on our way. It was shocking.

Saturday was our last day of monitoring, Karolina, Jacek and I went to “Gruszka” and “Miłek”, sadly we couldn’t find any butterflies. Magda, Łucja and Ola went to Bobrów, Sobiesz, Podzamcze and there were no butterflies. This last day was hard for us, because our volunteer time was coming to an end but we all had a lot of fun through all these days and  it was such an amazing experience.

The effect of climate change on the Apollo butterfly

Posted By: Maureen 88 Views 0 Comment ,

Written by Maureen Nieuwschepen

This article is the second in a two-part, scientifically-based series on Parnassius apollo.

Worldwide climate change effects – changing weather patterns and shifting temperature ranges

Climate change, caused by increased levels of greenhouse gasses, is leading to changing weather patterns and an increase in extreme weather events worldwide (Scott, 2016), with an increase in daily temperature and precipitation extremes especially. For example, there has been an increase in daily record-high temperatures in Europe compared to daily record-low temperatures and this ratio is projected to increase in the future (Ummenhofer & Meehl, 2017). As air temperature increases, air water holding capacity will also change, influencing precipitation patterns. Heavy rainfall events and the duration of dry periods are increasing and are expected to increase in intensity in the future (Scott, 2016), thereby negatively affecting terrestrial ecosystem production across biomes (Zhang et al., 2013). Other climate change effects significantly impacting terrestrial ecosystems are, for example, increased numbers of heat waves and wildfires (Ummenhofer & Meehl, 2017).

For Europe specifically, climate change has led to an earlier onset of summer, with a change of ~10 days between 1960 and 2000 (Cassou & Cattiaux, 2016). The projected effects of climate change on terrestrial Europe are looking grim. Not only is Europe subjected to worldwide trends in climate change-induced weather effects, such as increases in precipitation extremes and severity of droughts, but Europe also faces unique challenges according to climate prediction models (Carvalho et al., 2021).  Mean temperatures have increased almost double compared to the global average rate (Harris et al., 2014). This trend is predicted to persist in the future, with the highest relative temperature increase in Iberia, the Mediterranean, the Alps, Scandinavia, and Eastern and Northern Europe (IPCC, 2018). 

Climate change effects specifically for central Europe and P. apollo habitats 

Parnassius apollo (Linnaeus, 1758) habitats are mainly located in central European highlands. Climate change disproportionately affects mountainous areas, with more severe temperature rises than other ecosystems (Nogués-Bravo et al., 2007). Also, mountains are unique in their gradient of microhabitats along an altitudinal scale, which makes them harder to place into generalizable patterns. An upward shift in the distribution of plant and animal species has already been detected in European mountain areas (Lenoir et al., 2008), as temperatures are generally lower at higher altitudes. For plants, it is already established that the projected habitat loss is more significant for species found at higher elevations. 36-55% of alpine species, 31-51% of subalpine species, and 19-46% of montane species can lose over 80% of their suitable habitat by 2070-2100 (Engler et al., 2011). 

Effect on P. apollo

Temperature increases

As P. apollo habitats are situated in mountain areas, they have been and are subjected to climate change to a severe extent. Firstly, increasing temperatures drive butterflies northwards. During the last few decades, P. apollo retracted northwards along both the northern and southern boundaries of its range (Parmesan et al., 1999).  Another response to the rising temperatures might be the earlier onset of larval hatching. 

In the French Brançon region of the Alps, populations exhibited earlier larval hatching, along with a one-month shift in the emergence of flying adults in biotopes above 1900 a.s.l. (Descimon et al., 2005).

Weather anomalies

Weather anomalies caused by climate change might have catastrophic effects on P. apollo populations. Several events have been documented that caused big declines in population sizes or caused bottlenecks. The events have been documented before the year 2000 but do show the vulnerability of Apollo populations to weather anomalies.

In the Pieniny mountains in 1957, following an early and warm spring, a prolonged period of cold and rainy weather accompanied by snowfall in July caused a bottleneck for the regional P. apollo populations (Żukowski 1959). As males emerge from pupae earlier than females, those emerging in June could not mate due to the absence of females. Subsequently, when females did appear after the cold weather, only a limited number were fertilized as only a few males survived. 

A ‘false spring’ event in winter, i.e., a warm period followed by a return of the cold, in the late 1980s caused the decline of P. apollo populations in the southern part of the Central Massif in France (Descimon et al., 2005). A repetition of the event ten years later caused the complete extinction of these populations.

P. apollo larvae are adapted to low ambient temperatures, including temperatures below 0°C. The dark pigmentation of their cuticle enables rapid warming in sunlight for feeding. This trait is considered crucial in mountain habitats, where the maximum daily temperature rarely exceeds 15°C during the larval development stage (Richarz et al., 1989). However, larvae are highly susceptible to humidity. On cold and rainy days, larvae stop feeding and significantly reduce their locomotion. Consequently, extended periods of heavy rainfall, especially when combined with low ambient temperatures, decrease larval development and increase mortality rates (Descimon et al., 2005). However, temperatures above 40°C may also significantly increase larval mortality rates as they become more prone to developing opportunistic diseases, i.e., infections (Descimon et al., 2005). 

Natural forest expansion

Across Europe, forests are common climax ecosystems, especially in the central and northern regions of the continent. The progression of forest succession significantly challenges P. apollo populations, leading to the fragmentation of habitats and reducing the food plant availability for both larvae and adults (Nakonieczny et al., 2007). So far, this process has mostly affected lowland areas. Consequently, natural succession of forests has been mostly threatening ‘telephiophagous’ forms, i.e., feeding on S. telephium, of P. apollo, rather than the forms feeding on S. album.

However, the alpine grasslands above the treeline inhabited by P. apollo are also severely threatened by climate change due to upward forest expansion driven by increasing temperatures (Hülber et al., 2020).  This means that the albophagous forms are also threatened, especially when taking the predictions for temperature increase at higher altitude into consideration.

Conclusion

 Climate change affects both P. apollo populations, the availability of host plants for caterpillars and habitat persistence. Small and isolated populations are more susceptible to extreme weather conditions, which can lead to a bottleneck effect or complete extinction of the local population. Efficient conservation strategies are essential for the survival of the species, and will enhance habitat conditions for other species thriving in similar environments.  Projects like LIFE Apollo2020 are crucial in developing and implementing these strategies, playing a vital role in the conservation of P. apollo.

LIFE Apollo2020 Partner Meeting and Monitoring Visit in Saalfelden, Austria

Posted By: Maureen 241 Views 0 Comment

From July 22nd to 26th, 2024, the partners of LIFE Apollo2020 gathered in Saalfelden, Austria, for their annual meeting. This yearly event provides opportunity for all partners to engage in discussions, share updates, and collaborate on strategies to work towards the project’s goals. We had the pleasure to also welcome EU representatives Gustavo Becerra-Jurado from CINEA and Edyta Owadowska-Cornil from ELMEN EEIG, who shared their insights and assistence in regard to the project.

Day 1: Office day and Apollo habitat visit

The first day was dedicated to presentations and discussions. This “office day” allowed partners to discuss the projects’ progress and challenges. Meeting in person contributed to shared learning and collaborative problem-solving. As a refreshment break, we visited a local Apollo butterfly habitat (Stossengraben). The day concluded with a joint dinner.

Day 2: Habitat visits in East Tyrol

On day 2, we visited the project habitats in East Tyrol, including Virgen, Hinterbichl, Leisach, and Mörtschach. The highlight of the day was witnessing Apollo butterflies flying in Hinterbichl. To see the butterflies flying is a great motivation for everyone to do even more to conserve the Apollo butterfly species. The journey back to Saalfelden was equally memorable, as we took the scenic high alpine Grossglockner Road. The good weather allowed some breathtaking views of the Austrian Alps along the way.

Day 3: Habitat and breeding station visits and meeting conclusion

On the final day, we visited the habitats close to Saalfelden: Lofer and Fieberbrunn. In Lofer, we had the pleasure to watch a demonstration by dr. Leo Slotta-Bachmay from Naturschutzhunde and his dog, showing how trained dogs are used to search for and monitor caterpillars. The demonstration was very informative and inspiring, highlighting the many possibilities in which dogs can assist humans in reaching their goals. After the habitats, we visited the breeding station in Saalfelden, where Otto Feldner provided an in-depth look at the breeding process of Apollo butterflies. He has been breeding Apollo butterflies for more than 30 years and we could appreciate his dedication to reintroducing the species into its natural habitat.

Migratory history and ecology of the Apollo butterfly

Posted By: Maureen 131 Views 0 Comment ,

Written by Maureen Nieuwschepen


This article is the first in a two-part, scientifically-based series on Parnassius apollo.

Origin and migratory history

The Parnassius genus first originated in Laurasia (now West-China, Fig. 1) in the early Paleogen (about 65 million years ago). The collision of the Indian tectonic plate into the Asian continent, during the Miocene epoch (23.03 – 5.33 million years ago), resulted in the formation of the Himalayan mountain ranges in Central Asia and thereby a dramatic change in habitats. The Himalayan plateau blocked the Asian monsoon and reduced precipitation in Central Asia (Quade et al., 1989), which led to an increase in steppe plants. The changes in biotic (host plant shift) and abiotic (climate change and orogeny (i.e. mountain formation by converging tectonic plates)) conditions led to the first large-scale radiation of Parnassius into more than 50 species (Condamine et al., 2018). 

Figure 1. World map showing the origin and radiation center of the genus Parnassius (orange) and the approximate current distribution of Parnassius apollo (blue). Information retrieved from Nakonieczny et al., 2007.

Further diversification

One Parnassius species, Parnassius apollo (Linnaeus, 1758), dispersed far westward towards Europe and northwards until the permanent snow cover border (Nakonieczny et al., 2007).  During this time, it was still a vast steppe species. The first glaciation in Europe drove P. apollo southwards into refuges (Nakonieczny et al., 2007). Further subsequent glacial-interglacial cycles fueled the expansion and retraction of P. apollo and its occupations and withdrawals in and out of refuges. These ongoing dynamics most probably have led to the further subspecific evolution within P. apollo, leading to over  200 described subspecies in Europe (Todisco et al., 2010). Similar, but to a lesser extent dynamic, processes occurred in the Asian P. apollo range, explaining the difference in subspecies variety between Europa and Asia.

Current distribution

The shrinking steppe habitat in Europe posed selective pressure on P. apollo, leading to a gradual change from a typical steppe species to a mountain-steppe species (Nakonieczny et al., 2007). Now, P. Apollo is considered a steppe and mountain-subalpine-sub boreal species, occupying many different habitats in a wide distribution range (Descimon, 1995).  Its extensive Palaearctic range spans from 7° W (Cantabrian Mountains, Spain) to 120° E (Yakutia, Russia), including the Khentei Mountains in Mongolia. Its latitudinal distribution spans from 62° N (western Finland and Oppland, Norway) to approximately 38° N (Sierra Gádor in Spain, La Madonie massif in Sicily, Mt. Erímanthos in Greece, and West Taurus massif in northeastern Turkey) (summarized from several sources by Nakonieczny et al., 2007)(Fig. 1).

Description

The appearance of P. Apollo makes it one of Europe’s most iconic butterflies, with its 50-80 mm wingspan, chalk-white wings, grey markings, and black and red spots. Males and females differ in their patterns on the fore and hindwings, indicating sexual dimorphism. The different subspecies vary in size, wing shape, and wing pattern. However, the red spots are always present on the hindwings (Bonin et al., 2024).

Figure 2. Female Parnassius apollo

Apollo habitats in Europe

P. Apollo habitats in Europe typically consist of dry calcareous grasslands and steppes in upland areas, and alpine and subalpine grassland. Rocky habitats and screes are also suitable, but below an altitude limit dependent on the mountain range (up to 1,800 m a.s.l. in the Carpathians, 2,500 m a.s.l. in the Alps, and 3,000 m a.s.l. in the Sierra Nevada (Nakonieczny et al., 2007). Regardless of habitat type, the availability of suitable food plants for the larvae is crucial.  

Figure 3. Map of Europe with Parnassius apollo distribution in blue ( Information retrieved from Nakonieczny et al., 2007.)

Host plants

P. apollo is an oligophagous species, i.e., it is restricted to a few specific food sources. Larvae (caterpillars) feed on Sedum album (Linnaeus, 1758) (Fig. 4) or Hylotelephium telephium (Linnaeus, 1758) (Fig. 5) (Nakonieczny & Kędziorski, 2005). These are Sedum species, or stonecrop, which can live in dry conditions due to their CAM strategy (Crassulacean Acid Metabolism) (Wai et al., 2019). Lowland P. apollo populations primarily feed on H. telephium, as it grows in open forests and meadows. In contrast, higher altitude P. apollo populations predominantly feed on S. album, a species found in calcareous rocky environments (Stephenson, 1994).  This divides European P. apollo populations into ‘telephiophagous’ forms, feeding on H. telephium and ‘albophagous’ forms, feeding on S. album. Flying adult butterflies rely on a broader range of nectariferous plants for their nectar source, depending on the availability in the area (Massolo et al., 2022).

Figure 4. Sedum album
Figure 5. Hylotelephium telephium

Life cycle

The P. Apollo life cycle (Fig. 6) lasts one year and is univoltine, i.e., overwintering in the egg stage (Bonin et al, 2024).  Females lay eggs that remain dormant over the winter and hatch in the spring of the following year.  The larvae feed on the host plants until they develop fully in size while going through several molts. After this phase, the caterpillar turns into metamorphosis, becoming a pupa. The pupa does not feed but relies on the energy stored from the food it consumed as a larva (Gilbert et al., 1996).  While in the pupa state, the metamorphosis of larva to adult butterfly occurs through a complex series of biochemical reactions, controlled by neural and hormonal mechanisms (Gilbert et al., 1996).

Release of 50 Apollo butterflies in Czechia!

Posted By: Kamila Redererova 109 Views 0 Comment

On Wednesday, June 12, 2024, the Czech partner JARO released 50 Parnassius apollo butterflies into the Krkonoše mountains! They set out to inspect the quality of the environment, which we have been preparing for them in cooperation with many partners for the third year as part of the LIFE Apollo2020 project.

David Číp from the International Conservation Group JARO told that the release of the Parnassius apollo into the wild was preceded by the modification of a selected and undisclosed location to suit the butterfly, which is at risk of extinction in the Czech Republic and abroad. The organizers of the project perceive this butterfly, which became extinct in the Czech Republic in 1935, as a symbol of the protection of mountain nature. In the 1980s, it was managed to return to Štramberk in northern Moravia, where a weak population still lives.

“Now, together with the KRNAP Administration, the Škoda Auto Foundation and other partners, we are trying to return him to Bohemia, where he last lived in the Krkonoše and Podkrkonoše about 100 years ago. We have been trying for the return of rare ash trees for the third year,” said David Číp. Last year, an attempt at the first test release of butterflies failed due to complications at the butterfly rescue station. “However, the breeding technology was modified, so this year the third generation hatched, which can finally go out,” said Číp.

Conservationists will observe whether the butterflies will thrive in the restored conditions of the Krkonoše nature. “The experts we work with believe that we have managed to restore the conditions for Parnassius apollo in the field to such an extent that it could be enough for the Apollos to stay in the place we are preparing for them after release,” said project coordinator Tereza Macečková from the Group JARO.

So far, conservationists have released only males, so that possible losses of difficult-to-bring individuals are as small as possible. “Females are the most valuable for further breeding. However, if the released males are kept, they start behaving naturally, looking for females that hatch only after the males in the wild, and they stay here for several days after release, the chances of their permanent settlement will be much greater,” said Číp.

According to him, next year it will make sense to release the females as well and try to move to the last final phase of the project, when the Apollos could start to reproduce in the wild. “At the moment, we are roughly half way there, although perhaps the hardest part is behind us,” said JARO Group butterfly breeder Miloš Andres. According to him, the breeding of rare species of butterflies is very demanding, even if it is “only” about rearing the eggs to the adult stage. The most demanding task, which takes several years, he identified as the preparation of the environment for the butterflies in combination with their release without the need for additional reinforcements from breeding.

Conservationists keep the butterflies secret instead of releasing them to prevent them from being caught by a collector. They wrote a number on the top of each butterfly’s wings. “It is both for the sake of records, but also for their protection. They are so worthless to potential collectors,” said Číp.

Last year, conservationists in the Krkonoše improved about a hectare of overgrown rocky terrain and already noticed the spread of rare species of flowering plants and insects, which occur sporadically in the Krkonoše due to lack of space. The project is also focused on the restoration of entire biotopes, taking care of Parnassius apollo helps to protect other sensitive species. “Hopefully the released males will give us hope that we are moving in the right direction and we will have the chance to meet this beautiful butterfly in the Krkonoše Mountains permanently,” added Radek Drahný, spokesman for the KRNAP Administration.

The practical part of the LIFE Apollo2020 international project to protect the Apollos, one of Europe’s most endangered butterflies, started in 2022 in several areas of Central Europe. The mission for his return to the Krkonoše Mountains is carried out by members of the JARO Group in cooperation with the Czech and Polish Krkonoše Mountains National Park, the Nature and Landscape Protection Agency and a number of other Czech and foreign organizations.

The mission for the return of the king of butterflies to the Krkonoše Mountains will be implemented from 2021 by members of the JARO Group in cooperation with the Administration of the Giant Mountains National Park, the Nature and Landscape Protection Agency, members of the Czech Entomological Society, employees of the Entomological Institute of the Biological Center of the Academy of Sciences of the Czech Republic and partner organizations from Poland, Czechia and Austria.

Nature Restoration Law,  called shortly NRL, aims at the restoration of the EU’s land and sea ecosystems. Its goal is to reverse the severe decline of the EU’s nature where currently only 15 % of habitats are in good condition. NRL, for the first time in history, obliges states to put adequate measures in place to restore ecosystems – precisely at least 20% of the EU’s land and sea areas by 2030, at least 60% by 2040, and at least 90% by 2050.

For the first time in history, legally binding targets aiming at ecosystem restoration will be introduced in the EU at this scale. The NRL was being prepared and negotiated for a very long time. It passed through many changes in the process to finally be voted in the EU Parliament in November 2023. Even though, the new regulation has been passed in the EU parliament, it was waiting to be adopted by the EU Council until now. Thanks to the change in vote from the side of Austria and Slovakia, the required majority has been obtained and Nature Restoration Law has been sealed.

Importance of the NRL for Parnassius apollo and all other pollinators.

This law will play a major role in the restoration of all ecosystems and support all species. Here few aspects of how it will impact wild pollinators:

-Major threats for pollinators, such as fragmentation of habitats and low biodiversity in agricultural land areas will be now addressed systemically and real measures will have to be introduced by states to prevent and reverse these processes.

-States will need to put measures in place to reverse the declining trend of pollinators by 2030.

-States will need to plan and submit national restoration plans to the EU Commission, showing how they will deliver on the targets.

-As states will need to measure the accomplishment of the targets, data about pollinators can become a very important source of information for evaluation for them.

-The Grassland Butterfly Index will be optional to measure the biodiversity enhancement in farmland areas, which gives importance to pollinators as indicators of biodiversity.

What can we contribute as one of LIFE’s projects 

There are different ways in which LIFE projects can contribute to a larger perspective. Through providing data, developing and communicating best practices for conservation, and sharing experiences built through cooperation with a very diverse stakeholder network.

Data on pollinators, so on meadows and grasslands are important to monitor conditions in the proximity of and on agricultural land.  LIFE projects build best practices – for example on grazing to enhance the biodiversity of grassland, and need to adjust agro-environmental schemes for extensive grazing for these solutions to become reliable sources of income for farmers and therefore more popular solutions.

Grazing for conservation

As part of the LIFE Apollo2020 project, we work to improve conditions in grassland habitats and cooperate with multiple stakeholders: public and private, including forestry, farmers, owners of quarries and local citizens. We collaborate with all of them to build a network of habitats for the species. We also spread knowledge on the value of having biodiverse ecosystems and the many advantages of having diverse species as neighbours.

We collect the best practices on grasslands and Apollo conservation. In collaboration with all these stakeholders, we navigate challenges and look for solutions which can benefit local communities and different species. Without dialogue with all these stakeholders, our conservation actions would not have a chance to last. We will be happy to contribute our experiences and knowledge to help reverse the fragmentation of habitats, which is a serious threat to so many species.

The landscape mosaic with diverse connected natural habitats is what many species miss to be able to choose the most suitable spot for their activities – whether to hide from the heat, escape the flood or just feed. Connected habitats also ensure the possibility for migration of the species to find new locations/partners. Nature Restoration Law will be a very important step to be able to recreate secure and healthy conditions for different species to live, including us – citizens.

Knowledge of habitats lies on many levels, including local knowledge. Those working on the LIFE projects have a chance to collect very diverse experiences and have a significant role to play as a messenger between local, scientific, national and international levels. As one of LIFE projects – we are here to contribute in this messenger role. We encourage everyone to document and exchange knowledge.

We are restoring the splendour of Kruczy Kamień nature reserve, PL

Posted By: Kamila Redererova 179 Views 0 Comment ,

We are restoring the splendour of Kruczy Kamień nature reserve – the most important place for the Apollo butterfly in the Polish Sudetes 

Kruczy Kamień is an inanimate nature reserve. It was established in 1954 and currently has an area of 12.61 ha. It covers western and south-western slopes of Krucza Skała (681 m above sea level) located in the Krucza Valley, in the Stone Mountains. The subject of the reserve’s protection is an interesting form of trachyte intrusion (a variety of porphyry of volcanic origin) in the sedimentary rocks of the Rotliegend. The area is made up of steep slopes with heights reaching 30 metres in places. Numerous rock formations occur here, and in many places extensive fields of rock rubble are formed as a result of the crumbling of the porphyry rock.

Most of the reserve is covered with artificially planted spruce forest. The reminder is covered mainly by rocky, xerothermic, pioneer and meadow vegetation. Among the more important habitats recorded in the reserve are ecosystems of Pontic-Pannonian character, which form a mosaic with xerothermic and rocky grasslands. At the foot of the escarpment there are rare – Subcontinental Peri-Pannonian shrubby habitats Rhamno-Prunetea thickets with numerous patches of Cotoneaster integerrimus (one of the largest in the Sudetes) and herbaceous plants. The shrubs are also accompanied by Festuco-Stipion Pannonic grasslands, with Sedum species, important for the Apollo butterfly Parnassius apollo. Habitats of ephemeral character have developed on the rock rubble layer and in rock crevices. This is the thermophilic pioneer vegetation of the rock shelves of the Alysso-Sedion association classified as Sempervivetum soboliferi complex. This habitat type is rich in the succulent species Jovibarba sobolifera, Sedum acre, Sedum maximum and Sedum album (artificially introduced). The latter two species provide a food source for the caterpillars of the Apollo butterfly. These ecosystems undergo gradual succession, becoming overgrown with taller vegetation, mainly grasses and perennials and then shrubs and trees. At the foot of the reserve there are habitats rich in nectariferous plants: patches of xerothermic grassland and herbaceous vegetation, and further on, lush and dense meadow vegetation composed largely of Centaurea and Cirsium species.

Rare plant species, including those protected by law in Poland, include: the endemic morphological form of Viola porphyrea, Cotoneaster integerrimus, Festuca pallens, Lilium martagon, Digitalis grandiflora, Melampyrum sylvaticum, Antennaria dioica and Asplenium septentrionale.

A rich insect fauna, especially butterflies, was found in the reserve. However, the most important has always been the local subspecies of the Apollo butterfly Parnassius apollo silesianus, which occurs here. This butterfly became extinct at the beginning of the 20th century, and the Krucze Mountains area was one of the last places of its occurrence in Lower Silesia. The first successful attempt to reintroduce the species in the reserve was made as early as the 1990s, and the butterflies persisted in the site for more than 10 years. Reintroduction continued in the 21st century, when breeding began as part of a project by the Fundacja Ekorozwoju, the Karkonosze National Park and the Stołowe Mountains National Park, which now continues under the Apollo2020 project. The habitat itself has also been cared for. Unfortunately, years have passed since the last conservation measures in the reserve. The sunny slopes have again become overgrown with shrubs and tree undergrowth. The thermophilic habitats have been shaded and the landslides have started to lose their dynamic character.

This winter, Klub Przyrodników carried out conservation measures in the reserve that will help to preserve and, in places, restore its peculiar charm. An area of approximately 1.7 hectares was cleared of shrubs (with the exception of Cotoneaster integerrimus), as well as tree undergrowth, including some larger specimens, the seeds of which are spreading along the slopes of Krucze Kamień reinforcing the succession process. Our further aim is to maintain the effects of these activities and stop the regrowth of felled shrubs and trees by grazing goats. 

In spring, Apollo caterpillars can be seen in the reserve, which have hatched from the eggs laid by butterflies last year, and every summer, the spectacle of philutically flying Apollo butterfly plays out before our eyes on the slopes of the reserve and in the meadow at its foot. Our dream is to establish a permanent population of the species in the reserve, which will only need our help to cut the bushes.

Outdoor season in Austria has officially started!

Posted By: Kamila Redererova 190 Views 0 Comment ,

The snow has started to melt in the Alps, which means that the outdoor work season for the Apollo butterfly in Austrian habitats could officially begin. With the great help of volunteers, the Austrian team (EWS) has started the crucial task of debushing in two Apollo habitats – Lofer, Salzburg, and Fieberbrunn, Tyrol.

With warm and sunny weather on our side, we focused on clearing away overgrown bushes and trees to uncover the rocky slopes beneath. These rocky slopes are vital for the survival of Apollo caterpillars, as they provide the perfect environment for the caterpillars to thrive. The exposed slopes are ideal for the growth of Sedum plants, which are the main food source for the caterpillars. Keeping these areas free of excessive bush growth is important to maintaining a suitable habitat for the caterpillars.

In addition to our debushing efforts, we planted various Sedum species (Sedum sexangulare and Sedum album) to ensure the caterpillars have plenty of food. This step is needed for helping the caterpillars grow into healthy pupae and eventually transform into imagines. To support the adult butterflies, we also sowed seeds of nectar-producing plants, ensuring that there will be nectar sources available when the butterflies emerge.

The highlight of the day was discovering numerous Apollo caterpillars within the habitat. In Lofer, Salzburg. We saw them actively crawling and feeding on the Sedum plants, which was an exciting confirmation that our conservation measures are already paying off.

During our work, we had the pleasure of meeting a group of children and their teacher. The kids were eager to learn about the Parnassius apollo butterflies, their feeding plants, and our conservation efforts. Their enthusiasm and curiosity has again assured us how important is to involve and educate also the younger generation about environmental conservation.

Looking ahead, we are excited for the rest of the spring and summer seasons. We will continue our efforts to maintain and improve the habitats, ensuring that the Apollo butterflies have a thriving environment.

The rescue mission for Apollo continues in Czechia

Posted By: Kamila Redererova 204 Views 0 Comment ,

Last year, our Czech partner ČSOP Hradec Králové managed to light up (not only) over a hectare of densely overgrown rocky terrain for Parnassius apollo, which was covered with impenetrable trees and thickets up to 15 metres high. But our efforts did not end there! Thanks to long-term support from the Škoda Auto Foundation and a partnership with the KRNAP administration, this winter we have managed to open an area that is now two to three times larger than some of the sites where Apollo still survives in Slovakia or Poland.

The work is really extreme and dangerous, and in some places you literally have to do magic on a rope. Through the Krakonoš Gardens project, we have been able to purchase special equipment that allows us to safely reach even the most inaccessible places.

And that’s not all. So far we’ve only focused on one main location, but in the coming period we’ll start preparing a second home for the Butterfly King, which is nearby. We have also walked the surrounding area in detail, mapping the occurrence of both feeding and nectar plants, as well as the surrounding meadows and potential corridors that can serve as a network of stepping stones for the Apollo. These are the kind of microhabitats that help the butterfly king to cross the road when travelling to a new home or mate. It’s a bit like imagining the stones you use to hop from one side of a river to the other.

We’re looking forward to getting the place all smelling and buzzing. Last year, the restored rocky areas have already attracted various species of flowering plants and insects, which had not had enough space and light here before, including, for example, Hornet moth tied to the Spurges or Zygaena ephialtes, which was known on the Czech and Polish side of the Krkonoše Mountains from only one location, although it used to be common here in the past. And thanks to the new finds of rare butterflies last year, it is now indisputable that the activities aimed at the return of Parnassius apollo are helping several of the rarest butterfly species in the Krkonoše Mountains, such as the least and forest Small blue or the Silver-spotted skipper, to survive.

Apollo, as this massive mountain butterfly is also called after the god Apollo, is facing great difficulties today. Its numbers are declining rapidly across central Europe due to deteriorating conditions in its natural habitat, which are affected by both human activity and climate change. Even in the aforementioned sites in Poland and Slovakia, it is no longer thriving, mainly due to the abandonment of traditional farming practices, where excess and sprawling plants were regulated primarily by grazing animals. Last year, Parnassius apollo numbers declined by somewhere up to 90%. This project could thus play a key role in conserving the Central European gene pool of this iconic species and maintaining the population of this butterfly in our region.

The caterpillars of the next generation of Apollo hatched from eggs in the rescue kennel a few weeks ago, and now there are hundreds of them. The actual hatching of the butterflies could take place in June, after which we plan the first experimental release of males at the Krkonoše sites where the field work mentioned last year took place. It does not make much sense to reshape the habitat according to the so-called “human view”, even if we are convinced that our efforts are correct. By observing certain behavioural traits of butterflies, which they can demonstrate directly in the field, we can learn from unnecessary mistakes and guide our efforts in the right direction.

Outreach activities in White Carpathians

Posted By: Roman Manak 298 Views 0 Comment

As our project continues, so does our centre (Education and information centre Bílé Karpaty) continue to create educational and teaching aids. But how to test if these tools work as we imagined? The best way, of course, is to try them out directly while working with the children for whom they are primarily intended. The best time for such a trial is when setting up the Apollo Gardens, which have been introduced on this website before (for example, in the article Two Apollo Gardens built).

We have managed to build four such gardens in the past year, each in partnership with a school. All four gardens are raised beds that we have constructed in a pre-selected location. The rest was up to the children. With undisguised joy and enthusiasm, the children became gardeners and filled the bed with soil and levelled its surface. They then placed larger and smaller stones, which they had brought themselves, on a part of the bed to create a small rock garden. They poured silica sand into the slits between the stones.

Then came the main thing. Since the Apollo Gardens are meant to be an environment for both adult butterflies and their caterpillars, the prepared bed needed to be enlivened with nectarous plants for the adult butterflies and host plants for the caterpillars. The children planted white stonecrop plants in the sand of the rock garden and randomly planted small common houseleek among them. Although it is not an important food plant for caterpillars, caterpillars can occasionally use it and it is a nice diversion to the rock garden. Next to the rock garden, the children planted great stonecrop – another important food plant for caterpillars.

What about the rest of the bed area? The children had already guessed that the flowering plants that the adult butterflies need to live would come here. We provided meadow plant mix seeds for this purpose. A significant part of this mixture consisted of seeds of the Apollo´s favourite plants (various pink and purple flowering plants) and the rest of the seeds were other meadow plants to make the bed more varied, attractive to other pollinators and to keep it flowering for as long as possible.

An indispensable part of creating each bed was the time we spent with the children talking about the life cycle of butterflies, their importance in nature and other things. Of course, we also introduced in detail our main hero, the Apollo butterfly, the reasons why it has disappeared from our nature and how we can help it. At this point it was also our turn to try out some of the tools we had already created. A great success was always achieved by the Apollo pupa, several meters long, which the children climbed through, and on the other side, an adult Apollo emerged from them. Equally enthusiastic was the preparation of a sweet drink (represented nectar in flowers for the adult butterflies) and tattoos with all the developmental stages of the Apollo.

We have not only used the tools and materials to build Apollo Gardens, but also at several other events for the public. The children enjoyed the activities and we believe they will not forget Apollo right away. Among other things, it was confirmed to us that even ordinary coloring according to a template still has its charm and can entertain children.
