Nice outcome of the Vanishing Treasures project with @unep.org and a large team of regional collaborators (🙏).

Once again: context specificity matters! Even under the same climate change scenario in the same ecoregion, some landscapes will require conflict mitigation measures, while others will offer restoration opportunities.

Regionally diverging results under climate change:
- more overlaps between snow leopards and pastoralism in the future Tajikistan (below)
- less overlaps and increasing spatial separation of wildlife and pastoralists in Kyrgyzstan

Tobias Kuemmerle @tkuemmerle.bsky.social · 3d

We used species distribution models to analyze the current and future distributions of (a) snow leopards, (b) their prey, and (c) pastoralist - and how they overlap - for two large landscapes in Kyrgyzstan and Tajikistan. Spatial overlaps signal interactions and the potential for conflict.

Our new review lays out a framework for understanding the social-ecological benefits of protected areas to their surroundings - just published in One Earth:

doi.org/10.1016/j.oneear.2025.101462

Figure 2. Picture showing a geographic visualization of the seven categories of spillover from protected areas
They include (1) physical spillovers, (2) ecological spillovers, (3) societal and sociocultural spillovers, (4) economic spillovers, (5) political and/or legislative spillovers, (6) management spillovers, and (7) spillovers to physical infrastructure. These categories are explained in more detail in the text.

Heute ist Tag der Menschenrechte.
Gestern haben sich die EU-Gremien auf eine deutliche Abschwächung der Lieferkettenrichtlinie geeinigt.🤯
Das ist ein Schlag ins Gesicht für Menschenrechte entlang von Lieferketten.💔

Meme: Auf einem Grabstein hinter einem frisch aufgeschüttetem Grab steht "Menschenrechte in Lieferketten". Neben dem Grab posiert ein Mann in der Hocke, grinst in die Kamera und zeigt das Peace-Zeichen mit den Fingern. Auf ihm steht "EU-Politiker*innen und Wirtschaftslobby"

What does this mean? Actual habitat use of E. bison does not support views that they are forest specialists or that they are restricted to forests 👉 Restoration opportunities across diverse landscapes. However: potential for crop damages --> reintroductions should focus on low-conflict areas.

Tobias Kuemmerle @tkuemmerle.bsky.social · 20d

- Wild E. bison inhabit a wide range of landscapes
- Human influence strongly mediated habitat use
- Higher human influence --> bison used forests more and grasslands less during the day and more during the night

Tobias Kuemmerle @tkuemmerle.bsky.social · 20d

Some key findings:
- E. bison select for forests and avoid open areas at the landscape scale
- Within home-ranges, selection for forests during summer, for croplands during winter
- Grasslands were never strongly selected
- Within forests, younger and disturbed forests were selected

Tobias Kuemmerle @tkuemmerle.bsky.social · 20d

Analyzing these data in a functional response framework revealed variation in E. bison habitat use
- across spatial scales (home range vs. landscape)
- in different seasons (winter vs. summer)
- during day vs. night
This helped to reveal a more complex picture of E bison habitat use.

Tobias Kuemmerle @tkuemmerle.bsky.social · 20d

Past habitat assessments have often focused on individual herds, with many herds never analyses. Thanks to a broad collaboration among E. bison researchers and practitioners, we could analyze data from >240 GPS-tracked 🦬! Massive thanks to all collaborators!

Wild European bison can thrive in a wide variety of landscapes - including human-dominated ones.
