U.S. Parks - endangered species
Aux Etats-Unis, il y a différent parc national avec une diversité grande de espèces, quelques de ces espèces sont en voie d'extinction. Ils sont en voie d'extinction parce que humains détruire leur environnement, mais humains ne sont pas les uniquement problème. Dans la Vallée de la Mort, on peut trouver beaucoup de espèces en voie d'extinction, comme les Amargosa Crapaud, Tortue et de Saules Gobe-Mouches. Dans les Îles de Canal, tu pouvez trouver beaucoup espèces marin, certaines de ces espèces sont en voie d'extinction, comme le Rorqual Boréal , Baleine Rorqual , L'ormeau Blanc et de L'ormeau Noir. Au parc national de Yosemite, nous avons trouvé deux espèces terrestre en voie d'extinction, ils sont le renard de Sierra Nevada et Carcajou.
major endangered species
Death Valley
Death Valley National Park has many endangered species. The Amargosa Toad, are so endangered that we do not know how many are left, but they are part of the endangered species act. Southwestern Willow Flycatchers are dying quickly, the dams, water withdrawal, livestock grazing and sprawl of humans have taken up more than 90 percent of their habitat. Leaving the bird vulnerable to other birds. Ever since population survey began, Devils Hole Pupfish population haven’t gone over 553, in the fall of 2006 there were only about 38 fish left, and the 2 refugee populations were lost. The Desert Tortoise is also one of the many endangered animals in Death Valley National Park, the tortoise’s population has decreased by 90 percent since the 1950’s. The Desert Tortoise, are vulnerable, when they are in their burrow’s off freeway cars can smash the burrow or den and kill the tortoise, they are also threatened by diseases, pet owners who let sick tortoises out in the wild, putting wild tortoises in danger. The trash that lingers doesn't help either, they can mistaken it for food and it provides a false sense of fullness making them starve themselves, also ravens eat young tortoises because their shell isn't thick enough, the ravens pick at the shell till it breaks and eats what is inside.

Channel Islands
Channel National Park just so happens to inhabit the Sei Whale Rorqual. The whale was a target of commercial whaling, which is illegal, once the whalers killed most of the Blue Whales and Fin Whales. The Sei Whale Rorqual isn’t the only whale Channel National Park has, the Finback Whale. During the twentieth century the Finback Whale was hunted to the max, since 2003 there is a minimum of 2,541, and they are still struggling to repopulate. The White Abalone has been overfished, it is really threatened by commercial and recreational fishing, there is approximately only 1,600-2,500 fish left. The Black Abalone is currently on the endangered list because of overfishing and disease. The disease is withering syndrome, the Black Abalone has gone extinct in most areas, when will it go extinct in Channel National Park, hopefully never. The Black Abalone been fished since the mid-1800s, but when scientists started to see a decline in it was in the late 1970s. (“Channel Islands”)

Yosemite
At the Yosemite National Park we found two endangered animals, they are the Sierra Nevada Red Fox, and the Wolverine. The Sierra Nevada Red Fox likes to hide in rocks and burrow in soft soil, but no matter what it likes to do its still endangered. This is due to lack of food, and poachers, for their fur which is a beautiful reddish orangish color. The Wolverine attack humans, but I wouldn’t blame them, poachers are after the poor Wolverines for their claws. Also the wolves in the area seem to love Wolverines. (“Yosemite”)

Their protection is important
Death Valley
Death Valley National Park operates with approximately half the funding needed to manage and protect its 3.4 million acres. Because of this funding shortfall, 40 percent of approved park positions remain vacant. The park's most pressing needs are in the area of law enforcement, natural and cultural resource management, and facility maintenance.
The park has only 14 protection rangers, down from 23 a few years ago, to assist visitors in a timely manner or adequately protect artifacts, plants, and animals from vandalism and poaching.
Death Valley also lacks resources to develop strategies to reverse the population decline of the endangered Devil's Hole pupfish, a barometer for the condition of other threatened and endangered aquatic species in the Death Valley region. Cultural resources are also at risk as no maintenance program exists for the vast majority of Death Valley's backcountry mining and homesteading sites, many of which are on the threshold of falling apart, becoming lost history, and safety hazards.
Current maintenance staffing levels only allow or addressing emergency roadwork and have resulted in a deteriorated road network with many areas that the local tow truck operator refuses to serve. In addition, the park's visitor center is antiquated and the leaky roof needs to be replaced. Lastly, Death Valley icon Scotty's Castle is in a state of disrepair and funding is desperately needed for cleaning, preservation, and curation of castle furnishings and artifacts. (“Death Valley”)

Channel Islands
Plants and animals living on islands are especially vulnerable to extinction due to the physical boundaries, limited populations, and lack of genetic variability. One threat to these island species are non-native, invasive species. Non native species may have a negatively impact to the environment. For example, many non-native species are plants that grow or spread aggressively, taking over important wildlife habitat, devastating shelter and forage, and reducing the diversity and quality of native habitat. These weeds often do not hold and protect the soil the way native plants do, early half of the endangered animals in the United States have been negatively affected by non-native, invasive species. In addition, these species cause an estimated $138 billion in economic damage each year in the United States.

Yosemite
Studies believe that the Wolverine was never high in numbers so, the Yosemite National Park is not doing anything to protect the endangered species. But for the Sierra Nevada Red Fox, there is a study currently going on, as they search for more information on how to help this animal. Unfortunately there is no protection for this animal, until further notice. (“Yosemite”)
