For the study of protected animal species, biologists should follow some steps. Those animals which are in protective condition are placed in the natural environment so that they can live their natural life and can reproduce easily. So, for inspecting the animals in their area, the biologists should move on to the area where they live. Along with this, they have to apply for permission to enter into the habitat of the animals because they are protected. We know that entering into a protected area is not possible without permission.
