chêne pédonculé

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.

ours blanc

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
