Farming the forest steppe – results of the SASCHA project summarized
Our interdisciplinary research project SASCHA has come to an end, and most results are now published. As scientific papers are not accessible to everyone, we have now summarized the results in a brochure for stakeholders and the general public.
SASCHA was a research collaboration between eight Russian and German institutions, and aimed to provide tools for more sustainable farming in the Western Siberian grain belt. The economic and social dimensions of food production in Russia were linked to the maintenance of ecosystem functions and biodiversity in an era of growing food demand.
Ecology Across Borders: Joint Annual Meeting 2017 was the first time the Ecological Society of Germany, Austria and Switzerland (GfÖ), the British Ecological Society (BES), the Nederlands-Vlaamse vereniging voor ecologie (NecoV), and the European Ecological Federation (EEF), the umbrella organisation of the European ecological societies, organised their annual meetings together.
Amur Bird Project Meeting at ILÖK
On Saturday, 9th of December 2017, the annual meeting of the Amur Bird Project took place at the Institute of Landscape Ecology (ILÖK) in Münster, Germany. More than 45 participants, including guests from Kazakhstan and Russia, listened to 12 presentations in three sessions. A wide range of scientific topics based on the data collected at Muraviovka Park and Far East Russia´s Amur region covered diverse aspects of ecology, habitat use, fire impact, biodiversity as well as parasites, population trends and migration of birds. Furthermore, additional results were presented on eight posters. This was the 5th meeting of its kind, the largest one so far and the first one to take place in Münster. I want to thank Norbert Hölzel, Johannes Kamp and the staff of the ILÖK for making this meeting possible, and many thanks to all speakers, the Amur Bird Project team and all visitors for their contributions resulting in a great and successful meeting.
Yellow-breasted Bunting: uplisted to Critically Endangered, consumption and trade go on, but there is hope
Yellow-breasted Bunting, once a superabundant songbird species, has declined by 85-95% since the early 1980s, with heavy, illegal persecution in China being an important driver. The species' status has recently been updated to Critically Endangered on IUCN's international Red List, based on a quantitative assessment of the decline led by Johannes Kamp of the Biodiversity and Ecosystem Research Group.
However, birds are still caught and sold in larger numbers, even on eBay-like platforms in China. A price of 15-30 USD per bird suggests high demand. Good news is that conservation organizations along the flyway are raising awareness, see e.g. this excellent video from Hongkong. Also, the Chinese law has been changed, and hunting and consumption are now criminal offences.
More research is underway to shed light on the year-round distribution and flyways of the species. Data on migration routes have been retrieved from geolocator devices by Wieland Heim. This will help us to identify key areas for conservation of the species, and learn more about potential additional drivers of the decline, such as land-use change and agricultural intensification on the wintering grounds.
Imagining the future of Kazakhstan’s agriculture and biodiversity
Scenarios are gaining importance as tools to outline and compare potential future land-use trends, and assess their impact on biodiversity. We have used scenario planning exercises successfully on smaller scales in Russia (publication). In parallel, we are now outlining how agriculture might look in neighbouring Kazakhstan in the year 2050, on a near-countrywide scale. On 15/11/2017, researchers of project BALTRAK from the IAMO in Halle, the Kazakh research institute TALAP and our group organized a workshop in Kazakhstan’s capital Astana that brought together policy makers, agricultural enterprises, experts from international organizations such as FAO and UNDP, and researchers from Kazakh universities. In small groups, the attendants discussed four different scenarios, reaching from an imagination of highly intensive, industrialised agriculture over collapse and consolidation in subsistence systems to an ‘eco’-scenario with state-subsidized organic and climate-friendly production. The screening of the scenario storylines and main drivers by a wide range of experts as well as the engaged discussion opened up new horizons for all participants.
Leaf traits of steppe plants in response to aridity
A new paper ‘Quantitative mesophyll parameters rather than whole-leaf traits predict response of C3 steppe plants to aridity’ by Larissa A. Ivanova, Polina K. Yudina, Dina A. Ronzhina, Leonid A. Ivanov and Norbert Hölzel got published last week in the leading plant science journal New Phytologist. The paper is a first significant output of a cooperation between our lab and the plant ecophysiologists group around Larissa Ivanova and Leonid Ivanov from the Botanic Garden Institute of the Ural Branch of the Russian Academy of Science in Ekaterinburg. Further papers dealing with plant trait reponses across the entire latitudinal climate gradient in Central Eurasia from desert to tundra are currently on the way.

Award for the "fit for climate change" project Davert
The project "Fit for Climate Change", run by the NABU Naturschutzstation Münsterland and the State Enterprise for Forestry and Timber North Rhine-
Westphalia with scientific supervision by our working group, developes measures for a sustainable, near-natural adaptation of wet forests in the Münsterland to climate change. For the successful work, the project was now awarded UN Decade project.
This year our group organized a field campaign in early summer in Central Kazakhstan to sample field data of grazing impact on biodiversity and ecosystem services in rangelands along a steep climatic gradient over 350 km from desert to dry steppe in the so called ‘hunger steppe’ (Betpak Dala). This work is part of the BIODESERT survey coordinated by Fernando T. Maestre, running the Dryland Ecology and Global Change Lab at Rey Juan Carlos University (URJC), Madrid, Spain. Besides Norbert Hölzel and Frederike Velbert from our lab, Salza Palpurina and Viktoria Wagner from the Masaryk University, Brno (Czech Republic) as well Tatyana Siderova (senior botanist) and Asel Esengalyeva (Bachelor student) from our partner organization ACBK (Association for the Protection of Biodiversity of Kazakhstan) participated in the survey. Our expedition was joined by a group of five Russian eco-physiologists from the Ural branch of the Russian Academy of Science in Ekaterinburg under the lead of Larissa Ivanova.
We studied grazing gradients in three locations representing the climatic zones of northern desert, desert steppe and dry steppe. Sampling was done using a comprehensive standardized protocol, which included e.g. 1000 pin point measurements, 100 vegetation quadrats, plant traits, as well as dung and soil samples. To finish a single plot, we worked on average with 5 person for one full day (8-10 h). In parallel our Russian colleagues from Ekaterinburg undertook eco-physiological measurements of the dominant plants in the respective communities including measurements of photosynthesis and whole leaf traits and prepared frozen leaf samples for further analysis in the lab. Within the framework of the BIODESERT survey, covering drylands worldwide, our plots will be the only one from Central Eurasia the largest consecutive dryland area in the world. Meanwhile our soil and plant samples from Kazakhstan arrived safely in Madrid for further processing. First results of the worldwide survey are expected in the forthcoming year. One aim of the survey is to define thresholds of ecosystem degradation through grazing in global drylands. The following pictures give impressions about the fieldwork in remote areas with partly harsh conditions.
Successful fieldwork in Russia´s Amur region
The floodplains in the Amur region are one of the global hotspots of threatened biodiversity. Since 2011, the Amur Bird Project is studying endangered species and monitors bird population trends, coordinated by Wieland Heim. This year a team of volunteers and students of Münster University worked again for three months in the wetlands. One of the highlights of the field season was the recapture of several birds tagged with light-level geolocators in 2016 – for the first time we will now be able to analyze migration routes of songbirds along the East Asian flyway.
Besides the annual activities we also focused on fire impact on habitat use and return rate of the threatened Yellow-breasted Bunting. First results were already presented during the 11th conference of the European Ornithologist´s Union in August 2017 in Turku/Finland. How plant and bird diversity is shaped by man-made fires was surveyed again by Ramona Fitz. One of the “looser species” is the Swinhoe´s Rail – only recently we were able to describe the previously unknown song of this rare and less-known bird.
We hope to continue our projects in cooperation with Muraviovka Park in the next years.
Field course in the forest tundra of Western Siberia
As new collaborations with partners in Russia are emerging, several of our students are currently near Nadym, Western Siberia for a two-week field course.
Here, in the Russian forest tundra ecosystem, they support Ramona Fitz with her fieldwork for research on the effect of reindeer grazing and fire on the tundra ecosystems. The group also comprises students and researchers from the russian University of Tyumen, the Scientific Research Centre of the Arctic in Nadym and the Interregional Expedition Center "Arctic" in Yamal. The participanty are now busy with sampling vegetation, plant fuctional traits, biomass and soil along a gradient of fire history. We hope to establish a long-term collaboration using the Russian partners field station up in the north of Western Siberia.
British colleagues visiting the floodplain meadows at the Upper Rhine
British colleagues from „Floodplain Meadows Partnership“ lead by Professor David Gowing came to visit the floodplain meadows at the northern Upper Rhine in June.
Matthias Harnisch, project manager in Riedstadt, and Norbert Hölzel, doing research in the projects since years, took their guests to old floodplain meadows as well as 20-years-old and new restoration sites. The colleages were impressed to see the species-rich and diverse sites and the successful restoration projects.
Last sunday, with best sunny weather, most of of the lab members went to see pasqueflower and daffodil in the Eifel mountains and enjoy a day outside together.
Benefits of post-Soviet land-use change on soil carbon sequestration
Recently a paper of our working group, dealing with the effects of post-Soviet cropland abandonment on soil carbon sequestration in Western Siberia, got published online in Global Change Biology. The paper is based on a unique field data set with more than 470 sampling points across three test areas and stratified by land-use type that were collected in the course of the SASCHA-Project. Our results yield clear empirical evidence that abandoned croplands in Russia are currently a climate-relevant sink of atmospheric carbon. Research was conducted in close cooperation with colleagues from the University Applied Sciences in Osnabrück and Tyumen State University in Western Siberia.

A winter visit to the Yamal tundra
Upon invitation by the government of the Yamal-Nenets autonomous district in the very north of Western Siberia, Norbert Hölzel and Ramona Fitz joint an international conference on “Preventing the dissemination of infectious animal diseases on climate change” held in the city of Salekhard at the polar circle from November 9th to 11th, 2016.
The conference topic was directly related to the first outbreak of Anthrax in Yamal since 1940 in July 2016 which killed 2.400 Reindeers and a 12 year old boy of a Nenets reindeer herder family. The Anthrax outbreak was most likely triggered by the extraordinary warm weather conditions in summer 2016 causing a deep melt down of permafrost soils that exposed persistent Anthrax spores. Russian and international experts from reindeer husbandry, veterinary science and grazing ecology discussed how such outbreaks can be controlled and mitigated under ongoing climate change.
Yamal is the last stronghold of reindeer husbandry worldwide with more than 14.000 indigenous people maintaining a nomadic life style, currently keeping ca. 750.000 Reindeers. During a helicopter excursion to the Tundra of the southern Yamal peninsula the conference participants were introduced to the peculiarities of regional reindeer husbandry and the nomadic life style of Nenets people.
Meeting in China on Conservation Measures for the Endangered Yellow-breasted Bunting
In 2015, member of our group had helped to reveal the catastrophic population collapse of what was once one of the most abundant bird species of Eurasia, the Yellow-breasted Bunting. At that time, we concluded that ongoing illegal persecution of the species for food was one of the main reasons of the decline.
From 2-4 November 2016, a workshop was organized in Guangzhou, China, by Birdlife International, Sun Yat Sen University and the Hongkong Birdwatching Society. It aimed to bring together representatives of all countries that host Yellow-breasted Buntings during the breeding season and in winter, from Russia and China to Myanmar and Thailand. Each country provided an update on current population trends and threats to the species. Much emphasis was put on a prioritization of conservation measures, such as better enforcement of laws against illegal trapping and awareness raising among wildlife consumers. A new wildlife law will be approved in 2017 in China and there are high hopes that it will give the Yellow-breasted Bunting a higher level of protection. Exciting collaborative projects on research and conservation involving multiple range states were also agreed.
A Special Issue of Biodiversity and Conservation on the ecology and conservation of the Palearctic steppes is now out, including eight publications of our Working Group - one new synthesis paper and several papers on results of the projects in Russia (SASCHA) and Kazakhstan (BALTRAK).
