There is no "US Fish and Wildlife Department." I must assume that you mean the US Fish and Wildlife Service, which is part of the US Department of the Interior.
Governments could ensure wildlife habitats by putting animals into preserves , refuges, provincial and national parks , that way you could protect animals from certain kinds of human activities.
The fifteen US executive departments are Treasury, Commerce, Homeland Security, Agriculture, Education, Defense, Housing and Urban Development, Health and Human Services, Labor, State, Energy,Veterans Affairs, Interior, Transportation and Justice. In most cases the function of each department is clear from its name. Interior deals with such things as national parks and forests, wildlife preservation areas, waterways ,water rights, and Indian affairs.
