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.

- 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

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

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.

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.

Fliegen wird billiger, Zugfahrten teurer.

Das entscheidet die Regierung zum Start der 30. Klimakonferenz.

Und dann wundert man sich, dass die Leute wenig Vertrauen in die Politik haben.

Die Antwort ist: ja! Elch (und wahrscheinlich auch Wisent) kommen wieder und würden bei uns genug Lebensraum finden, wenn wir sie willkommen heissen. Mehr dazu hier: www.hu-berlin.de/de/pr/nachri... ... und der wissenschaftliche Artikel hier: doi.org/10.1111/ddi....

"...what happens in Sweden matters far beyond Sweden. If a country with some of the world’s largest intact boreal forests chooses to double down on short-term extraction, it will not only undermine the EU’s climate goals — it will send a dangerous signal to other forest nations..."

🐺 Wolves have not yet reached a favourable conservation status in most European countries
🐺 Many populations do not meet the effective size required for long-term genetic and demographic sustainability
🐺 Wolf populations across Europe are primarily threatened by overhunting (incl. illegal killing)

All of this very true - there is no scientific basis for the change in legislation that was enacted this year:
🐺 Current monitoring does not allow for a reliable estimation of wolf numbers in Europe
🐺Available demographic data are heterogeneous, approximate, largely qualitative, and unverifiable.

Restore strict protection for wolves in Europe

What makes positive outcomes more likely during and after times of shocks? We suggest:
- proactively create resilient institutions,
- that are focused on local capacity building,
- that enhance social stability, &
- that are built on internal motivations for conservation

Socio-economic shocks are fairly common, especially at broader scales (key for large carnivores) and longer time frames (key for conservation planning). Consider shocks, and the risks and potential opportunities they bring is thus critically important (but rarely done).
