how many number of species does an endangered animal take for it to become unendangered?

Question

is it the same for all types of animals? cause i`m researching for sea otters && giant pandas. please i need help ASAP. thanks! x]]]

Answer 1

Endangered species status in the US is determined by the US Fish & Wildlife Service. Internationally, the IUCN (The International Union for the Conservation of Nature and Natural Resources) maintains a list of endangered species.

In any case, it's a judgment call, not a matter of any numerical decision point. They look at population trends, habitat loss, external pressures such as hunting, and other factors to identify endangered species. When they judge that the species has managed to establish a robust and stable breeding population, and that its habitat is secure, they remove it from endangered status.

Answer 2

The answer is depends on the species and how wide-spread it is.

Generally, you need at least 1,200 individuals in one group. For plants, you need 10 times that number.

For example, consider the dwarf cinquefoil, a plant in the White Mountain National Forest in New Hampshire. Prior to receiving Endangered Species Act protection in 1980, the known main population of Robbins’ cinquefoil numbered only 3,700 plants. In was delisted in 2002, when the population was more than 14,000 plants.

Answer 3

You mean number of critters, not species, right?

Remember the purpose of all this: that the animal doesn't die out.

You need enough that you can have a stable (as opposed to vanishing) population.

I'd imagine it would depend on the type of critter.

I bet if you went to environmental protection sites, you could get specific targets for when this or that critter will be taken off the list.

Answer 4

That is a VERY good question, and one I have never thought of. I suppose it must vary between species, and probably has to do with the number of populations, genetic diversity within them, reproduction rates, predation and habitat threat.

Answer 5

well i would say that untill you can only see them at a zoo and that if there is one in then wild that if you killed it you could actually go to prison!
