Habitat & Geographic Range

gray wolf

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

wild boar

Habitat

Inhabits tropical and subtropical moist broadleaf forests within the Neotropic biogeographic realm.

Range

Widely distributed across Africa (5 countries), Asia (5 countries), Europe (12 countries), North America (14 countries), Oceania and the Pacific (14 countries), and South America (8 countries).

gray wolf

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.

wild boar

The ancestor of domestic pigs, wild boars are robust, omnivorous ungulates weighing up to 200 kg, found from Western Europe through Asia and North Africa in diverse habitats including forests, wetlands, and grasslands. Highly adaptable and prolific breeders, they have become invasive in many regions including North America and Australia. Their rooting behavior disturbs soil and vegetation, influencing forest structure and seed germination significantly.
