A comparative analysis of status assessments of polar bear, Ursus marinus. Among all of these lists, potential good primqck coverage should be predicted for Mexican turtles; however, there are some inquiries that should be made in order to know more about Mexican non-marine turtles’ conservation status.

It is also hard to tell if the difficult work has been done by the international agencies or by Mexican agencies? The Conabio List of Priority Species Conabio, is another list issued by the Mexican government and is based upon a closed workshop of specialists from the federal government, academia, national non-governmental organizations NGOsinternational NGOs such as cknservacion IUCN, and private consultants non-academics, but experts on conservation biology.

Certainly both succeed and fail, but the confusion generated by the lack of concordance makes conservation conservvacion difficult.
