Transformative changes for biodiversity and climate protection: Pensoft partners with EU project TRANSPATH

As an expert in science communication, dissemination and exploitation, Pensoft joins TRANSPATH for transformative changes at consumer, producer and organisational levels.

As an expert in science communication, dissemination and exploitation, Pensoft joins the Horizon-funded project TRANSPATH to identify leverage points and interventions for triggering transformative changes at consumer, producer and organisational levels.

Why TRANSPATH?

The magnitude of biodiversity loss and climate crisis has grown exponentially in recent years, which will inevitably lead to serious consequences at a global scale. Although reversing the degradation of ecosystems and reducing greenhouse gas emissions are top priorities for the European Union, science and policy communities are united in the belief that conventional policies alone are not enough to halt biodiversity loss or mitigate climate change.

In order to achieve climate neutrality by 2050, whilst simultaneously reshaping people’s relations with nature, we need transformative changes in our economies and societies urgently. 

How?

TRANSPATH (short for TRANSformative PATHways for synergising just biodiversity and climate actions) – a new European Union-funded project, plans to satisfy this need by accelerating diverse transformative pathways towards biodiversity-positive and climate-proofed societies, with sensitivity to social-cultural contexts and rights.

TRANSPATH will identify leverage points and interventions for triggering transformative changes at consumer, producer and organisational levels. A research team, consisting of leading academics, science-policy experts, and early-career professionals, will directly engage with diverse stakeholders, who affect and are affected by trade regimes and associated ‘greening’ mechanisms.

As a leader of WP5: Dissemination, outreach and catalysing transformative pathways, Pensoft is responsible for providing a dissemination and communication strategy, as well as taking care of the project branding and website. In addition, the Pensoft team is to organise joint activities with other projects or initiatives on transformative change and related topics.

What?

Funded by the European Union’s Horizon Europe research and innovation programme, TRANSPATH was launched on 1st November 2022 and will be running until October 2026. The official kick-off of the project took place online and was followed by an in-person kick-off meeting of all consortium members on the 2nd and 3rd February 2023 in Wageningen, the Netherlands.

For the next four years TRANSPATH will be focussing on the design and integrated assessment of a suite of transformative pathways that hold potential to accelerate shifts in unsustainable patterns of extraction, production, consumption and trade. The project’s mission will be achieved by four objectives:

  1. Set up a Policy Board and Science-policy-practitioner Labs at multiple scales to engage and jointly deliberate on implications of diverse visions and pathways of change.
  2. Identify and characterise leverage points for diverse contexts that lead to positive synergies between biodiversity, climate and trade domains.
  3. Integrate and customise European and global pathways by considering coupled biodiversity-climate actions and critical leverage points.
  4. Identify and test alternative interventions at global and European scales that can trigger transformative change at the level of consumers, producers and organisations.

TRANSPATH will bring together and advance several strands of recent research, which hold potential for triggering and accelerating transformative changes that can restrain biodiversity loss and climate change. 

The project will draw on diverse contexts in Eastern and Western Europe, Africa and Latin America, to engage with policy makers and practitioners, individuals, Civil Society Organisations (CSOs), small- and medium-sized enterprises (SMEs) and multinational corporations.

In addition, policy packages and other interventions will be designed to facilitate the emergence of leverage points at different scales of action in ways that change the decision-making framework of everyday choices.

These interventions take into account the synergies and trade-offs of actions across multiple individuals and locations, as well as the role of incentives and political obstacles to implementation.

The EU project will provide a suite of Transformative Pathways along with a Toolbox of Transformative Interventions to trigger and enable these pathways. The Transformative Navigation Toolkit assists practitioners in enabling and navigating these pathways, acknowledging that determining what constitutes a ‘transformative pathway’ is also a product of an iterative and adaptive process that emerges and evolves over time.

Whom?

The TRANSPATH project brings together leading academics, science-policy experts, and young professionals from different social-cultural origins across Eastern and Western Europe, Africa and Latin America. Represented by nine countries and twelve nationalities, the consortium comprises a diverse range of scientific disciplines in environments, economics, and social sciences.

Dedicated to ensuring sufficient engagement from local to global levels in this project, the experts are focused on integrated and inclusive deliberation that is essential for identifying, legitimising, and navigating transformative pathways.

Can deep learning help us save mangrove forests?

Object-oriented classification of fused Sentinel images can significantly improve the accuracy of mangrove land use/land cover classification.

Mangrove forests are an essential component of the coastal zones in tropical and subtropical areas, providing a wide range of goods and ecosystem services that play a vital role in ecology. They are also threatened, disappearing, and degraded across the globe.

One way to stimulate effective mangrove conservation and encourage policies for their protection is to carefully assess mangrove habitats and how they change, and identify fragmented areas. But obtaining this kind of information is not always an easy task.

“Since mangrove forests are located in tidal zones and marshy areas, they are hardly accessible,” says Dr. Neda Bihamta Toosi, postdoc at Isfahan University of Technology in Iran working on landscape pattern changes using remote sensing. In a recent study in the journal Nature Conservation, together with a team of authors, she explored ways to classify these fragile ecosystems using machine learning.

Comparing the performance of different combinations of satellite images and classification techniques, the researchers looked at how good each method was at mapping mangrove ecosystems.

“We developed a novel method with a focus on landscape ecology for mapping the spatial disturbance of mangrove ecosystems,” she explains. “The provided disturbance maps facilitate future management and planning activities for mangrove ecosystems in an efficient way, thus supporting the sustainable conservation of these coastal areas.”

The results of the study showed that object-oriented classification of fused Sentinel images can significantly improve the accuracy of mangrove land use/land cover classification.

“Assessing and monitoring the condition of such ecosystems using model-based landscape metrics and principal component analysis techniques is a time- and cost-effective approach. The use of multispectral remote sensing data to generate a detailed land cover map was essential, and freely available Sentinel-2 data will guarantee its continuity in future,” explains Dr. Bihamta Toosi.

The research team hopes this approach can be used to provide information on the trend of changes in land cover that affect the development and management of mangrove ecosystems, supporting better planning and decision-making.

“Our results on the mapping of mangrove ecosystems can contribute to the improvement of management and conservation strategies for these ecosystems impacted by human activities,“ they write in their study.

Mapping our ecosystems: Pensoft joined the Horizon Europe project MAMBO

With expertise in science communication, dissemination and exploitation, Pensoft is involved in this project set to develop new technologies for monitoring species and their habitats across Europe

With expertise in science communication, dissemination and exploitation, Pensoft became part of this project dedicated to new technologies for species and habitat monitoring across Europe

Background 

The European Union puts a great value in monitoring the health of ecosystems, as comprehensive mapping can aid policy makers’ work in adopting appropriate legislation for nature conservation. It allows for understanding the impact of human activities and making informed decisions for effective management of nature’s resources. This is particularly important for the EU, as it has set ambitious goals to halt biodiversity loss and restore degraded ecosystems by 2030, as outlined in the EU Biodiversity Strategy for 2030. 

Effective biodiversity monitoring can help the EU track progress towards these goals, assess the effectiveness of conservation policies and initiatives, and identify emerging threats to biodiversity. 

Despite this awareness, efforts to monitor animals and plants remain spatially and temporally fragmented. This lack of integration regarding data and methods creates a gap in biodiversity monitoring, which can negatively impact policy-making. Today, modern technologies such as drones, artificial intelligence algorithms, or remote sensing are still not widely used in biodiversity monitoring. 

MAMBO project (Modern Approaches to the Monitoring of BiOdiversity) recognises this need and aims to develop, test, and implement enabling tools for monitoring conservation status and ecological requirements of species and habitats. Having started in late 2022, the project is set to run for four years until September 2026.

Pensoft – with its proven expertise in communicating scientific results – is committed to amplifying the impact of MAMBO. Pensoft supports the project through tailored approaches to communication, dissemination and exploitation so as to reach the most appropriate target audience and achieve maximum visibility of the project.

Deep-dive into the project

In order to enrich the biodiversity monitoring landscape, MAMBO will implement a multi-disciplinary approach by utilising the technical expertise in the fields of computer science, remote sensing, and social science expertise on human-technology interactions, environmental economy, and citizen science. This will be combined with knowledge on species, ecology, and conservation biology. 

More specifically, the project will develop, evaluate and integrate image and sound recognition-based AI solutions for EU biodiversity monitoring from species to habitats as well as promote the standardised calculation and automated retrieval of habitat data using deep learning and remote sensing.

“Classification algorithms have matured to an extent where it is possible to identify organisms automatically from digital data, such as images or sound,”

comments project coordinator Prof. Toke T. Høye, Aarhus University. 

“Technical breakthroughs in the realm of high spatial resolution remote sensing set the future of ecological monitoring and can greatly enrich traditional approaches to biodiversity monitoring.” 

In order to achieve its goals, the project will test existing tools in combination with MAMBO-developed new technologies at the project’s demonstration sites geographically spread across Europe. This will contribute to an integrated European biodiversity monitoring system with potential for dynamic adaptations.

Pensoft is part of MAMBO’s Work Package 7 (WP7): “Science-policy interface and dissemination”, led by Helmholtz Centre for Environmental Research (UFZ). The work package is dedicated to providing a distinct identity of the project and its services through branding, visualisation and elaborated dissemination and communication strategy.

Within WP7, Pensoft will also be taking care after the launch of an open-science collection of research outputs in the scholarly journal Research Ideas and Outcomes (RIO). 

Amongst the tasks of the partners in WP7 is also the development of different pathways for integrating new technologies and innovations into the EU Pollinators Monitoring Scheme (EU PoMS; SPRING).

Illegal trade and poor regulation threaten pangolins in China

Unpermitted sellers are commonly found illegally selling pangolin scale products for the purposes of traditional Chinese medicine.

Pangolins, unique scale-covered mammals, are drastically declining in numbers across Asia and Africa, largely due to illegal trade. Part of the trade, both legal and illegal, supports the traditional Chinese medicine market, which has attracted conservation attention. The level of demand for pangolins and other animals in traditional Chinese medicine, however, hasn’t been thoroughly studied.

In a new study published in the journal Nature Conservation, Dr Yifu Wang, currently a postdoc researcher at the University of Hong Kong, investigated pangolin scale trade in China, interviewing staff in hospitals and pharmaceutical shops in two provinces (Henan and Hainan). Between October 2016 and April 2017, she and her team talked to doctors from 41 hospitals and shop owners and assistants from 134 pharmaceutical shops.

The research found pangolin scales and their derivatives were widely available in hospitals and pharmaceutical shops across Henan and Hainan Provinces. The legislation in place, however, has not been able to prevent ongoing illegal trade in pangolin products. Her team found that 46% of surveyed hospitals and 34% of surveyed pharmaceutical shops were selling pangolin scale products illegally.

“Existing legal trade allows 711 hospitals to sell pangolin products as medicine with regulations on manufacturer, package, and national annual sale quantity,” explains Dr Yifu Wang. “However, we show that pangolin scales are under heavy demand and unpermitted sellers are commonly found illegally selling pangolin products.”

“Quantities of products traded by permitted legal sellers are estimated to greatly exceed the supply capacity of legal sources,” she continues.

This widespread illegal trade, coupled with the very limited legal supply capacity compared to market demand, is concerning. The researchers point to the urgent need to reduce demand from traditional Chinese medicine on pangolin scales and revise the current legal pangolin scale trade system.

“We also highlight the importance of incorporating the traditional Chinese medicine sector into combating illegal wildlife trade and species conservation beyond pangolins,” they conclude.

The researchers plan to continue investigating the pangolin scale market in China to understand the trade after COVID-19.

Conversation on the shore: Interview with ecologist & geographer Kremena Burkhard

Kremena’s work on local coastal ecosystems in Germany aims to develop approaches and methodologies which can be applied in an international context.

The shore is a mutual caress. More than just a place of encounter between land and water, it is one of the physical and imagined thresholds between humans and the other-than-human world. This place of touch - through thoughts, actions, interconnections, and affect - is the inevitable crossing at the beginning and end of every inquiry into the world’s bodies of water. 

In the context of the UN’s Decade of Ocean Science for Sustainable Development, the Decade of Ecosystem Restoration and the recent historic High Seas Treaty to establish Marine Protected Areas in international waters, the world looks into the deep blue. Let us, however, linger on the way there for a moment. Let us breathe, and let the shore catch our breath.

This moment on the shore leads us to a conversation with Kremena Burkhard – a researcher at the Ludwig Franzius Institute of Hydraulic, Estuarine and Coastal Engineering at the Leibniz University Hannover, Germany. Kremena’s work focuses on the co-benefits and risks of carbon sequestration in coastal ecosystems. 

Late last year, she presented her most recent work at the 4th European conference of the Ecosystem Services Partnership (ESP), which won her one of the Best Poster Talk awards. 

I find the idea of improving the understanding of how ecosystems – and more generally the natural world – contribute to our well-being to be very inspiring and refreshing in a high-tech profit-oriented world,

she says to explain how she stays motivated in her research work.

To communicate this knowledge to policy- and decision-makers, as well as the general public is key, especially when we consider the threats of climate change and the fact that our deep dependency on nature seems to be largely undervalued,

she adds.
Kremena highlights the role of nature-based solutions:

When utilising conventional and  nature-based solutions, the focus is often on a single benefit that is demanded in a certain area, time and situation. 

In contrast to conventional solutions, nature-based solutions provide additional co-benefits. These may include biodiversity protection and other ecosystem services that address broader societal demands and are more sustainable in the long term.

As part of the CDRmare research mission “Marine carbon sinks in decarbonisation pathways” of the German Marine Research Alliance, Kremena’s work on coastal ecosystems aims to develop approaches and methodologies which can be applied in an international context.

Our project sea4soCiety focuses on the carbon storage capacity and co-benefits of four coastal vegetated ecosystems which play a key role as carbon sinks around the world and thus contribute to climate regulation. The analysis and methods developed in the project contribute scientifically to the studied topics and have an international relevance.

The German coast is representative of three coastal ecosystems, namely seagrass, salt marsh and macroalgae. The fourth ecosystem – that of mangrove forests in the tropics, is also investigated within the project as a key ocean carbon sink of global relevance.

But climate regulation is only one of the multiple services that these ecosystems provide. Coastal protection, water purification, food and material provision and recreation are among the key services of coastal ecosystems, the benefits of which are used and highly appreciated by the local communities and have significant role in the local safety, economy and culture. 

Kremena’s winning poster presented at the 4th European conference of the Ecosystem Services Partnership (ESP) (Crete, Greece 2022)
What are the strategies for mitigating or further analysing the risks of carbon sequestration in coastal ecosystems?

We prioritise conservation and restoration of coastal vegetated ecosystems, which are often heavily degraded, and we identify the most suitable areas for establishment of new ecosystems. This reduces the risk of carbon release and provides additional carbon sink capacity. 

Further risks are related to unknown climate change impacts. The sea temperature and hydrodynamics are changing, and we are not sure how those changes of habitat will impact the coastal ecosystems. We are studying their reaction in laboratory environments and in the field, identifying thresholds for their functionality and capacity to supply ecosystem services. 

Finally, the identification and mitigation of conflicts with other users of those ecosystems is also key to reduce the social risks for all beneficiaries, including labour, human rights, public health issues, and political uncertainty.

When it comes to stakeholders and non-experts, is science communication around the topic of carbon sequestration in coastal ecosystems effective?

On a national and international level, Germany seems to be on track with setting targets and planning actions to become climate neutral through the Climate Action Programme 2030.

The CDRmare research mission and in particular the sea4soCiety project on carbon sequestration in coastal ecosystems are in a way part of that effort, receiving funding to provide the knowledge base for the action programme. Thus, to some extent, the science communication on that level is working and the action plan is based on scientific knowledge. 

The shortcomings are in the implementation phase. Local governments are often lacking established mechanisms that allow and support the implementation of action plans related to the national targets. 

Such regulated implementation strategies should operationalise the uptake of scientific knowledge in the management of coastal ecosystems and by the local communities, and also in all fields of policy and management.

Protecting marine biodiversity: we take a look at science

In light of the UN’s High Seas Treaty, we look back at deep-sea science published in our journals.

Surely, March 2023 will be remembered with the historic agreement of UN member states to protect marine biodiversity in the world’s oceans. 

The so-called High Seas Treaty is a legal framework for the protection of marine biodiversity and responsible and equitable use of resources of areas beyond national jurisdiction (BBJN). Its draft, published on the 5th of March 2023, is the outcome of two decades of negotiations, and is part of the international effort to protect a third of the world’s biodiversity by 2030.

An unwavering dedication to the protection and conservation of biodiversity will be required to see the firm landing of this hopeful step.

On this occasion, we look back at some impactful studies published in our journals that have made waves, hopefully in the right direction towards impactful conservation measures and actions.

Following President Barack Obama’s expansion of the largest permanent Marine Protected Area on Earth (Papahānaumokuākea Marine National Monument) in 2016, a new species of coral-reef fish was named in his honour. The fish is the only known coral-reef species to be endemic to the Monument, and, despite its small size, it carries wide-reaching cultural and political significance as a reminder of how politics go hand in hand with science.

Dr. Sylvia Earle gives President Barack Obama a photograph of Tosanoides obama on Midway Atoll, from the film “Sea of Hope: America’s Underwater Treasures” premiered on National Geographic Channel on January 15, 2017. See also the news story on National Geographic.

Other studies from our flagship zoology journal ZooKeys have focused on the benthic megafauna and abyssal fauna of the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean.

The Clarion-Clipperton Zone, managed by the International Seabed Authority, has been targeted by deep-sea mining interests. In the context of heightened concern over potential biodiversity loss, scientific research is crucial for informing policy-makers and the general public about the risks and outcomes of such initiatives.

The rich biodiversity of the deep sea has also been documented in big-scale taxonomic inventories and checklists in the Biodiversity Data Journal.

Such examples are the publication of 48 new echinoderm records from the CCZ made during a single 25-day cruise, marking a ~25% increase of the echinoderm species records previously available in databases. Other notable contributions are the first image atlas of annelid, arthropod, bryozoan, chordate, ctenophore and mollusc morphospecies and the first image atlas of echinoderm megafauna morphospecies inhabiting the UK-1 exploration contract area and the eastern CCZ.

Hymenopenaeus cf. nereus observed in the UK-1 exploration contract area.
Image source: Amon et al. (2017).

Going forward, the expansion of Marine Protected Areas should also ensure the implementation of policies for the methods of resource extraction and their equitable sharing and use among the world’s nations.

Over the next few years, we hope to see an ever increasing interest in biodiversity conservation - from the general public, stakeholders and policy makers, and, of course, research institutions.

 We need to love what we protect in order to be able to protect it.

Southern Flying Squirrel rediscovered in Honduras after 43 years

The Southern Flying Squirrel (Glaucomys volans) was spotted in an area where forestry and silvicultural activities are carried out for the sustainable exploitation of pine logging and timber.

The presence of The Southern Flying Squirrel (Glaucomys volans) was documented in Honduras for the first time after 43 years. The record is from a site of the forest management plan called “Las Lechuzas”, municipality of Concordia, department of Olancho.

Apart from this newly confirmed location, the species has also been recorded in Zambrano, department of Francisco Morazán in 1935, in Gracias, department of Lempira, and finally in the Department of paradise in 1979. Based on these records, Honduras is considered the southernmost distribution known for this species.

The discovery was possible thanks to a project of El Aserradero Sansone, a company focused on sustainable forestry activities in Honduras, and is published in a research article in the peer-reviewed journal Check List.

This finding confirmed that there is at least one population of G. volans in the country, at the Las Lechuzas site, which is currently also the southernmost locality known in its global distribution.

The species has been assessed as Least Concern by the IUCN (meaning it has stable populations), but is considered Data Deficient on the Red List of Honduran species.  Considering the low number of records and the high rate of destruction of pine forests in Honduras, G. volans is a priority for conservation in the country.

In support of the conservation of the biodiversity of Las Lechuzas, the company Sansone is now committed to giving priority to the conservation of G. volans in the area. The use of artificial shelters for G. volans is also being studied, as the animal is at greater risk when its nests are disturbed.

Based on recommendations suggested in the study, Sansone will work to increase the quantity and quality of tree seedlings that will grow in the canopy and educate people in the community about the need to protect pine ecosystems and rare animals. Additionally, within the 3,139.62 ha of the management plan of Las Lechuzas, there are 836.63 ha that have been declared as hydrological protection zones. Currently, there is no record of G. volans in any protected area of Honduras.

“As a professional with an experience of 43 years, I capitalize on the detection of the Flying Squirrel as an event that opens the doors to the true dimension posed by the Honduran forest law in the proper administrative management. That includes biodiversity conservation and protection and rationality of the protection of natural resources. The latter turns out to be of greater importance in view of the strong social pressures in favor of the conversion of the use of forest land destined for extensive agriculture and livestock, as well as the environmental impacts caused by climate change that is being sustained by the mismanagement of our resources,”

says José Muñoz, one of the authors in the study.

About El Aserradero Sansone:

El Aserradero Sansone was founded in 1957, characterized by compliance with the laws of Honduras, especially those related to forest management. It has developed an evolutionary and progressive process of achievements in the implementation of management plans, including such related to the evaluation of environmental impacts.

In this sense, the environmental importance in the management of natural resources has continued to promote evolution, defining the need to venture into aspects related to the conservation of flora and fauna as well as the incidence of climatic and environmental factors in the administration of natural resources. Within this responsibility, the last challenge that the company Sansone is welcoming with great optimism lies in adhering to the international criteria and indicators of the forest certification process through the principles of FSC (Forest Stewardship Council) and through the GFA company of Hamburg, Germany.

Unraveling nature’s chorus: AI detects bird sounds in Taiwan’s montane forests

Researchers developed an AI tool which identifies 169 species native to Taiwan from the sound of their calls.

Montane forests, known as biodiversity hotspots, are among the ecosystems facing threats from climate change. To comprehend potential impacts of climate change on birds in these forests, researchers set up automatic recorders in Yushan National Park, Taiwan, and developed an AI tool for species identification using bird sounds. Their goal is to analyze status and trends in animal activity through acoustic data.

Prof. Hsueh-Wen Chang and Ph.D. Candidate Shih-Hung Wu from National Sun Yat-Sen University, Taiwan, Dr. Ruey-Shing Lin, Assistant Researcher Jerome Chie-Jen Ko from the Endemic Species Research Institute, and Ms. Wen-Ling Tsai from Yushan National Park Headquarters have published a paper in the open access journal Biodiversity Data Journal, detailing their use of AI to detect 6 million bird songs.

Compared to traditional observation-based methods, passive acoustic monitoring using automatic recorders to capture wildlife sounds provides cost-effective, long-term, and systematic alternative for long-term biodiversity monitoring.

The authors deployed six recorders in Yushan National Park, Taiwan, a subtropical montane forest habitat with elevations ranging from 1,200 to 2,800 meters. From 2020 to 2021, they recorded nearly 30,000 hours of audio files with abundant biological information.

However, analyzing this vast dataset is challenging and requires more than human effort alone.

To tackle this challenge, the authors utilized deep learning technology to develop an AI tool called SILIC that can identify species by sound.

SILIC can quickly pinpoint the precise timing of each animal call within the audio files. After several optimizations, the tool is now capable of recognizing 169 species of wildlife native to Taiwan, including 137 bird species, as well as frogs, mammals, and reptiles.

In this study, authors used SILIC to extract 6,243,820 vocalizations from seven montane forest bird species with a high precision of 95%, creating the first open-access AI-analyzed species occurrence dataset available on the Global Biodiversity Information Facility. This is the first open-access dataset with species occurrence data extracted from sounds in soundscape recordings by artificial intelligence.

The dataset unveils detailed acoustic activity patterns of wildlife across both short and long temporal scales. For instance, in diel patterns, the authors identify a morning vocalization peak for all species. On an annual basis, most species exhibit a single breeding season peak; however, some, like the Gray-chinned Minivet, display a secondary non-breeding season peak, possibly related to flocking behavior.

As the monitoring projects continue, the acoustic data may help to understand changes and trends in animal behavior and population across years in a cost-effective and automated manner.

The authors anticipate that this extensive wildlife vocalization dataset will not be valuable only for the National Park’s headquarters in decision-making.

“We expect our dataset will be able to help fill the data gaps of fine-scale avian temporal activity patterns in montane forests and contribute to studies concerning the impacts of climate change on montane forest ecosystems,”

they say.

Endangered vulture returns to Bulgaria after being extinct for 36 years

Preliminary results from the releases of Cinereous Vultures (Aegypius monachus) were published in the Biodiversity Data Journal.

The Cinereous Vulture (Aegypius monachus) – also known as Black Vulture, Monk Vulture or Eurasian Black Vulture – is the largest bird of prey in Europe.

Globally classified as Near Threatened, its populations in southern Europe, once abundant, have been experiencing a dramatic decline since the late 1800s. So dramatic, in fact, that by the mid-1900s, these birds had already been nowhere to be seen throughout most of their distributional range across the Old Continent. In Bulgaria, the species has been considered locally extinct since 1985.

Thanks to the re-introduction initiative that was started in 2015 by three Bulgarian non-governmental organisations: the leading and oldest environmental protection NGO in Bulgaria: Green Balkans, the Fund for Wild Flora and Fauna and the Birds of Prey Protection Society, the species is now back in the country.

The project, aptly named  “Vultures Back to LIFE“, where the Vulture Conservation Foundation (Switzerland), EuroNatur (Germany) and Junta de Extremadura (Spain) are also partners, has been co-financed by the LIFE+ financial instrument of the European Commission.

By mid-2022, the team imported a total of 72 individuals from Spain and European zoos, before releasing them in strategically-chosen sites in the Eastern Balkan Mountains and the Vrachanski Balkan Nature Park in Northwestern Bulgaria. 

The team brought 63 immatures from Spain, where the birds had been found in distress and rehabilitated in aviaries. The other nine juveniles were captive-bred in zoos, and then released by means of hacking, which involves an artificial nest, from where the fledglings can gradually ‘’take off” to a life in the wild.

The re-introduction campaign to date is presented in a research article, published in the open-access Biodiversity Data Journal. There, the scientists led by Ivelin Ivanov (Green Balkans), report on and discuss the effectiveness and challenges of the different release methods and offer tips on the conservation and re-introduction. 

For example, hacking proved to be inefficient for establishing an entirely new core (or nucleus) population of Cinereous Vultures in the Balkan Mountains in Bulgaria. It did not work for supplementing a small settled group of individuals either.

Instead, the team recommend the aviary method and delayed release, where captive-bred birds are introduced to the new locality after a period of acclimatisation, where the birds can gain life experience to the local environment.

 “The Cinereous Vulture re-introduction establishment phase in Bulgaria in the two first release sites is running according to the plan, and the first results are satisfactory,” 

the scientists comment.

“Two distinct nuclei are now created, and the species started breeding, which might be a reason to up-list it in the Red Data Book of Bulgaria from ’Extinct’ to ‘Critically Endangered.’”

These two newly created breeding nuclei of the Cinereous Vulture in Bulgaria are the second and third of their kind in the Balkan Peninsula. 

“Following a dramatic decline throughout the 20th century for decades, the species had remained in only one breeding colony in Dadia-Lefkimi-Soufli Forest National Park in north-eastern Greece. Now, exchange between the three colonies will facilitate the exchange of individuals, ensure long-term stability, and give rise to the regional population,”

the authors of the study say.

However, the team points out that further monitoring and modelling and adaptive management are indispensable for the long-term persistence of the new national population. Now that there is already evidence that the imported vultures have been successfully breeding in Bulgaria, there is one step left before it can be officially confirmed that the Cinereous Vulture species has successfully re-established in the country. This conclusion can only be made after the core breeding populations begin to produce about ten chicks every year and after the locally fledged individuals begin to reproduce on their own. Such results are expected by 2030.

The re-introduction of the Cinereous Vulture is the latest in a series of conservation projects focused on birds of prey in Bulgaria. 

First, in a programme that started in 2009, the Griffon Vulture was successfully re-introduced in Bulgaria after about 50 years of “extinction”. In fact, the team took a lot of the know-how and methods used in that project to apply in the present project. The success story was published in a research paper in the Biodiversity Data Journal in 2021.

In fact, the very same day in 2021 saw two publications in the Biodiversity Data Journal that reported on re-introduction successes involving birds of prey in Bulgaria, which had gone missing for decades. The second instance was the discovery of the first nesting Saker Falcons in twenty years

Both scientific publications are part of a dynamic ‘living’ collection, titled “Restoration of species of conservation importance”, whose aim is to collate publicly available research studies reporting on the reintroduction and/or restocking of animal and plant species of conservation importance around the world. The collection was inspired by the “International Scientific Conference on Restoration of Conservation-Reliant Species and Habitats” held in Sofia, Bulgaria, in 2020.

“The restoration of species is one of the most important conservation tools in the context of constantly intensified human-driven global biodiversity loss. The reintroduction/restocking activities are related to significant research and data gathering before and during the work process, which ensures their sustainable success,”

explain the collection editors.

Redefining nature-based decision-making: Pensoft joins EU project SELINA

“Ecosystem services is one of the topics that Pensoft has been involved in for over 10 years,” points out COO Prof Pavel Stoev.

Ambitious goals have been set by the European Union, in order to tackle the biodiversity conservation challenges over the coming decade. No less ambitious are the goals of the Horizon Europe project SELINA, which is one of the current major initiatives looking in the same direction. 

SELINA (Science for Evidence-based and Sustainable Decisions about Natural Capital) is a transdisciplinary project aimed at promoting the conservation of biodiversity, enhancing ecosystem conditions, and supporting the sustainable use of the environment through evidence-based decision-making.

As an experienced science communicator and open-science publisher, Pensoft will be leading the project’s communication and dissemination activities.

“Ecosystem services is one of the topics that Pensoft has been involved in for more than 10 years, so it was only natural for us to continue our work as a communicator of scientific information in the ambitious SELINA project as well,”

says Prof Pavel Stoev, COO at Pensoft.

“We have already collaborated with many of the partners within the earlier EC Horizon 2020 project ESMERALDA, which concluded with the launch of a pan-European network of scientific institutions engaged with biodiversity conservation and ecosystem services.

In addition, Pensoft has been strongly connected to the community through the scholarly journal One Ecosystem, which is supported by Ecosystem Services Partnership, and offers an opportunity for scientists in the field to publish their results in a new and innovative way.”

he adds.

The project

SELINA was launched in July 2022 and will run for 5 years. Having received EUR 13 million in funding, the project is seen as an unprecedented opportunity for smart, cost-effective, and nature-based solutions to historic societal challenges such as climate change, biodiversity loss, and food security. 

One of the project’s main objectives is to identify biodiversity, ecosystem condition, and ecosystem service factors that can be successfully integrated into decision-making processes in both the public and private sectors. 

To achieve this objective, SELINA will develop, test, and integrate new and existing knowledge, including methodological approaches to improve biodiversity, ecosystem condition, and ecosystem service information uptake by decision-makers. 

In addition, the project will utilise EU-wide workshops and multi-disciplinary Communities of Practice involving a wide range of stakeholders, including scientists, policymakers, business leaders, and civil society organisations. 

The project will also organise Demonstration Projects on biodiversity, ecosystem condition, and ecosystem service integration in decision-making and co-create a Compendium of Guidance that will allow stakeholders to make full use of the project’s results and fit-for-purpose recommendations with real-world applications in policy-making and business decisions. 

International consortium

SELINA project brings together experts from 50 partnering organisations across all European Union member states, Norway, Switzerland, Israel, and the United Kingdom.

The project comprises a Pan-European and transdisciplinary network of professionals from the academic and non-academic sectors with various (inter)disciplinary backgrounds – including ecologists, economists, social scientists – who have agreed to work collaboratively to support transformative change based on evidence-based decision-making related to the management of natural resources.
