Habitat & Geographic Range

American Bald Eagle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

Chocolate Milky

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and North America (United States). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

Chocolate Milky

The Chocolate Milky (Lactarius lignyotus) is a medium-sized ectomycorrhizal mushroom in the family Russulaceae, found in coniferous and mixed forests across Europe, North America, and temperate Asia. Like all members of the genus Lactarius, it exudes a milky latex when the flesh is broken — in L. lignyotus, this latex is white and acrid, contributing to the genus's widespread edibility variation. The fruiting body features a distinctive dark chocolate-brown to sooty-brown, velvety cap with a central boss (umbo), similarly coloured gills, and a dark brown stipe, making it relatively recognisable among forest mushrooms. It grows in close association with spruce (Picea) and fir (Abies) trees, forming ectomycorrhizal symbioses in which the fungal mycelium envelopes root tips and exchanges mineral nutrients for plant photosynthates, a relationship fundamental to the health of boreal and montane conifer forests. The IUCN classifies the chocolate milky as Endangered in certain regional assessments, reflecting declines in suitable habitat quality linked to changes in forest management, nitrogen deposition from atmospheric pollution, and climate change affecting the timing and abundance of fruiting. Accurate population monitoring of ectomycorrhizal fungi is challenging given that the fungal organism itself is largely subterranean, visible only when fruiting.
