Many people may be confused when they discover that one animal in the list of species may be so extinct in one state to another state that cannot be threatened in any way. This also applies to the neighboring countries. Part of the problem is that the answer is not as easy as it seems. However, this inequality can be explained.
The United States uses several lists of endangered species. One of them is a national list, which indicates that animals in all states and territories are rare and endangered and that the federal government needs protection. An example of an animal on this list was the American bald eagle. Although there have been multiple causes, including the widespread use of chemicals such as DDT, the Eagle was removed from national lists because they had an amazing return because of the laws and their implementation efforts. Surname
There are also lists of endangered species. These are maintained by the individual states and the lists can differ considerably from each other. It should be noted that the list does not apply to animals that had no reproductive population in the state they were in recently or in the recorded history. For example, alligators in Oregon or Washington are not considered endangered because alligators are non-native species. Maybe a few million years, when the weather was much warmer than today, there were lizards in the area, but long gone, so they have no place in the list.
Humans often help to reduce the number of animals of a particular species in a particular area. However, the actual cause is not important to know if an animal is on the list or not. However, the cause can be very useful to explain why one animal may be in danger in one state, but it could be well populated in another state.
An example of this is the ruthless trout. In some eastern states, this trout is considered endangered. The most likely cause was overfishing and human activities that destroyed the habitat of the river and the current. However, Oregon, Washington State and Montana, the cutthroat trout is far from being in danger and is usually pulled, though fishing is regulated as having all kinds of play. , In some rivers, there are so many tailors that a four-inch-mature adult is widespread, although these fish can be quite large if you get enough space and food. In fact, catch pressure helps them to be more stable in terms of quantity and size in some areas, such as those mentioned above.
Another example is the Pronghorn antelope. It is the fastest land animal park in North America and many states have put it in danger. Now they have only a few predators besides humans and can defeat any other animal. However, the Pronghorns are animals that are used to graze pastures. The areas in which they can do this have been reduced as people move to areas where they have their preferred grazing grounds. Antelopes have become rare in these areas.
However, in eastern Oregon, the pronghorn populations have increased significantly. Regulated Pronghorn Hunt is done; Keep the herds in the place where the earth can bear them. They are not abundant, but they are not even in danger. Oregon is not the only state where that's true.
The simplest answer to the question of why animals can be endangered in one state and not in another can simply be emphasized; Habitat and human action vary from state to state. However, to understand a person needs a little bit of knowledge about what it means to be at risk and to have the power that every state must apply to their lists and decide.
This also applies to other countries. That's because in England there are animals in danger lists that are not in danger in France, although the two are only about 25 miles apart, the width of the canal.
