The most endangered natural habitats in the United States of America include rainforests, native grasslands, wetlands, coastal areas, and high elevation coniferous forests. These habitats are threatened by climate change, logging, fires, real estate developments and pollution.
In particular, many animal species such as the grizzly bear, gray wolf, sea turtle, white shark and puma are at risk of extinction due to the loss of their natural habitat. Located on the Olympic Peninsula in western Washington state, the Hoh Rainforest is one of the largest temperate rainforests in the United States.
The park is now protected from commercial exploitation, but for much of the 20th century, the forest was heavily logged. And looking up at the towering trees, it's easy to see why the trees were so prized. Occupying the mountains of the southern Appalachians and stretching from southern Virginia through North Carolina, Georgia and Tennessee, the Appalachian temperate rainforest receives more than 60 inches of rain annually.
Some of the most endangered natural habitats in Canada and Alaska are: Tundra: The tundra is a fragile and sensitive habitat. Global warming is causing permafrost to gradually melt, which can lead to landslides, the disappearance of lakes and the loss of habitat for fauna that depends on the tundra.
Boreal Forests: The boreal forests of Canada and Alaska are threatened by deforestation, the extraction of natural resources (such as oil), and mining activities that destroy natural animal habitats.
The most endangered habitats in continental USA, Canada and Alaska
Ice Oceans and Seas: Coastal waters of Alaska and Canada are at risk from ocean acidification and growing oil traffic, which can cause significant damage to marine animals, fisheries and coastal communities .
Mountains and Glaciers: Alaska and Canada are known for their mountains and glaciers. However, global warming is causing a progressive melting of glaciers, which can lead to landslides and the disappearance of habitat for wildlife that depend on mountainous areas.
Rivers and Wetlands: The wetlands of Canada and Alaska are important habitats for marine mammals, migratory birds, and a variety of fish species. However, deforestation and urban growth are destroying and polluting these areas.
