    I am wondering if their is a site or database that allows you to look up the endangered species/ or animals/species population data.

    I am wondering how the national parks ... like yellow stone ,...etc know when a certain animal is endangered or how they collect/ know for sure they are accurate.

    For example Panda Bears are one animal that is on the endangered species list.
    I am curious how they know this for sure and if their is a way to measure/get the population data of certain animals in certain regions.

    Any environmentalist out their that can shed some light on this.
    I am very interested in how one can gather data accurately on animals?
    For people we can easily use surveys and tax forms to get a rough estimate on human population. (at least humans are a little easier to keep track of normally)
    But when it comes to animals seems to me it would be nearly impossible.... and nearly impossible to know if an animal is on the in dangered species list or not.... or weather it is going to be.

    Thanks your link explains most of what I wanted to know
    Your link

    But going by sampling in a small region the amount of particular animals doesn't always mean you are going to get a good approx. in the large always.

    For example if you counted how many ants in a 10ft by 10ft area approx. You cann't just say an accurate number of ants for all of a particular town or state would be just multiplying
    a 10ftx10ft area by a larger factor ...etc

    To put it interms of human population if we counted all the people in a Wyoming based town/state got an average we could not use that number and multiply it to get an accurate
    approx of the whole population of people in the US or in the world....etc

    The point is human population is more dense in certain areas and I would assume animal population in alot of cases would be no different.

    So with out a group of people assigned to count a specific region latitude/longitudes their would be no way to get a good density count. ANd with out a density count you would only have a very simple population measure that is not very accurate in most cases and wouldn't apply in most cases.

    Think about if I wanted to see how many ants lived in Antarctic (their is probably none) but the approx. method would say multiply number of ants in 10ftx10ft by a factor of how big the region is. (this is a stupid example that could easily be cleared up by experimenting on one ant to see what climate it could live in and factor that in.... but the point is still their)

    The whole point of environmental studies is that differant species have niches that require differant kinds of environments. So your 10' X 10' plot is good only if the two areas are the same in almost all respects. That is why real environmental studies require much time and effort.
