Common Oak

One of Europe's most important and widespread deciduous trees, the pedunculate oak can live over 1,000 years, reach 40 meters, and support the greatest biodiversity of any European tree species — over 2,300 species of insects, fungi, lichens, mosses, and birds directly depend on mature oaks. Found across Europe to western Asia in temperate forests, its hard, durable wood has been foundational to shipbuilding, architecture, and barrel making throughout history.

Eurasian beaver

Eurasian beaver (Castor fiber) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.
