cover for wildlife and fish. Different species of animals 

 find optimum habitat conditions at different stages of 

 plant succession. Research identifies these optimums, 

 and the normal variations about them, and provides 

 the scientific basis for deliberately managing fish and 

 wildlife. Some research is especially designed to 

 determine the interrelationships between wildlife 

 habitats and management for products such as timber. 

 There is new emphasis on habitats for non-game 

 species.

National Aeronautics and Space Admin- 

 istration, — Remote sensing and surface 

 measurements are used for surveying and assessing 

 wildlife habitats and population dynamics. Radar and 

 telemetric techniques are used in studying migratory 

 routes and the impact of land use and cultural pressures 

 on wild animals and on animal behavior in relation to 

 their migrations and territories. Decreases in funding 

 represent a phasing out of an animal tracking program.

 Fisheries and Wildlife studies the determination of 

 habitat requirements and relationships between 

 habitats and physical factors such as precipitation or 

 pollution, population trends on forest-wildlife and 

 pesticide-wildlife relationships, species distribution 

 and life history, and control of animal damage.

Smithsonian Institution. — The wildlife 

 management program of the Smithsonian is limited to 

 describing wildlife species and populations in natural 

 ecosystems, such as Panama and Chesapeake Bay, and 

 special studies in Africa. Studies of functions and 

 relationships of the wildlife with the environment are 

 mainly by the National Zoo and Tropical Research 

 Institute. Studies on social behavior and organization 

 of vertebrates in Panama and Africa are of importance 

 in wildlife management.
