Habitat & Geographic Range
Common Oak
Typically found in diverse terrestrial habitats from tropical forests to temperate regions.
Widely distributed across Africa (Lesotho, South Africa), Asia (Armenia, India), Europe (8 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (4 countries).
Gray/Purple Heron
Typically found in diverse ecosystems where prey species are available.
Found across Europe (6 countries).
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.
Gray/Purple Heron
A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
