The Most Threatened Wildlife in Every State

Federal wildlife officials have recently announced the presumed extinction of some 22 animals that formerly existed in the U.S., including 11 birds, eight freshwater mussels, two fish, and a bat. The source of their elimination is primarily human activity — the upsetting of natural evolutionary changes through habitat destruction, pollution, over-hunting and -fishing, and, potentially most devastatingly, climate change.

We can expect extinction numbers to grow at an unprecedented rate as human populations spread and the earth gets hotter. Two years ago, the United Nations sounded the alarm, warning that a million species of plants and animals around the world, out of eight million existing today, were threatened with extinction, and that climate change has accelerated the rate at which they will leave the face of the earth entirely.

The U.N. estimates that 75% of land environments and 66% of marine environments have already been altered by human activity, causing a 20% reduction in the abundance of land animals, as well as a potential reduction in fish biomass of up to 25% by the end of the century.

For the United States, the picture is less gloomy, at least for the immediate future, thanks to the Endangered Species Act (ESA), passed in 1973, which lists endangered and threatened species and provides for their protection and restoration. The law has, thus far, been a brilliant success, with 99% of listed species brought back from the edge of extinction. Most of the American animals now considered extinct, including many on the most recent list, died off before the enactment of the ESA.

What the ESA has taught us is that we can take effective action to slow extinction rates through sound management of human activities as they affect animal populations and habitat. Without such vigilance, animal species whose existence we have come to take for granted could disappear forever.

To determine the most threatened animals in every state, 24/7 Tempo reviewed the U.S. Fish & Wildlife Service’s Environmental Conservation Online System to find two animals listed as “endangered” that are native to each state. Information on the animals’ habitat also came from USFWS.

Detailed Findings & Methodology

Since the passage of the endangered species legislation, some animals have made a comeback. These include the American alligators, brown pelicans, eastern Steller sea lions, and the nation’s symbol, the bald eagle.

The road to preserving the nation’s endangered species is long. Even with more than four decades of legislated protection for endangered animals, the U.S. is ranked second worldwide in the number of endangered species by country, with about 1,500 domestic species threatened, according to the Mother Nature Network website.

The number of endangered species varies by state. Hawaii accounts for about 0.2% of the U.S. land area, but it is home to 25% of the federally endangered species, according to the Mother Nature Network. Among animals at risk in Hawaii is the Hawaiian monk seal, one of Earth’s most endangered animals. There are only about 1,000 in existence.

As one might expect, there are various species of sea turtles, rabbits, and cranes on this list. More generally, it includes mammals, marine animals, fish, insects, birds, amphibians, reptiles, and more. Some are more well known, like species of bats, butterfly, and salmon, while others are less known, like species of amphipod and limpet.

Included among the animals most at risk are different species of mollusks such as the spectaclecase, a freshwater mussel. Mollusks are often threatened because of dams, which disrupt water flow patterns and change water temperature. Losses of mollusks imperil the ecosystem because they are a food source for fish, and they recycle plant and animal waste that helps keep water clean.

To identify the most threatened animals in every state, 24/7 Tempo reviewed the U.S. Fish and Wildlife Service’s listing of endangered animals in the United States. Many of the endangered animals are not unique to one state but are threatened in a great number of states. Only 31 states have animals endangered only there. To find which of the threatened animals in these 31 states are most endangered, we turned to the International Union for Conservation of Nature’s inventory of threatened species. Many of the most threatened animals listed here were found to be “critically endangered” on the IUCN’s Red List. We used this same approach to evaluate the threat level of endangered animals in the remaining 19 states, but in these cases animals may be listed as endangered in other states as well.
