Hi, I am wondering if their are any environmental scientists out their that could answer this question.
How does one know if an animal is endangered. (like how do you obtain a population estimate of a particular animal or species)
For humans that can be done with tax forms , voters list, census , death certificates,...etc to get a good approx. to the population growth/death rates and population numbers of people in a particular area.
But for animals or other species its not like we can just ask them to fill out a form.
Even if we tag a few with tracking devices I find little data can be obtained on the population numbers or weather they are endangered or not or going to be in the near future.
Example
How did they know Panda Bears are endangered and an approx. number still alive.
How could one be certain that it was accurate?
Question 2)
Is their a centralize place (site/public database) to look up the populations number/statistics of a given animal/species and in what area they live or are found in ?
