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).

Closed-Leaved Pondweed

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Distributed across Cuba, Norway, and United States.

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.

Closed-Leaved Pondweed

Closed-leaved pondweed refers to aquatic plants in the genus Potamogeton (family Potamogetonaceae) characterized by leaves in which the sheath margins are fused to form a closed tube around the stem, rather than remaining open as in many related species. These submerged or floating-leaved aquatics grow in ponds, lakes, slow-moving rivers, and ditches across temperate regions of Europe, Asia, and North America. The distinctive closed leaf sheath is a key taxonomic character distinguishing certain Potamogeton species and provides structural support to stems in flowing water. Pondweeds are ecologically vital components of freshwater ecosystems, providing oxygen through photosynthesis, stabilizing sediments with their root systems, offering refuge for invertebrates and small fish among submerged stems, and forming important foraging habitat for migratory waterfowl that consume the starchy tubers and seeds. Many pondweed species have declined due to water quality deterioration from nutrient enrichment, increased turbidity, mechanical disturbance from boat traffic, and invasive aquatic plant competition in freshwater habitats across Europe and North America.
