injurious to forests and range plants. The development 

 of chemical formulations for treating seeds has made 

 possible the reseeding of thousands of acres of cut- 

 over forest lands in the Northwest which otherwise 

 would have been difficult to revegetate because of 

 seed-eating rodents. 



Through its studies of birds, mammals, and other 

 wild animals and their habitats, the Bureau seeks 

 out facts and develops techniques for improved 

 management of wildlife. (When wildlife workers speak 

 of "managing** wildlife they are referring to the 

 protection given a species and the preservation and 

 improvement of the environment in ,which it lives.) 

 One of its particular functions is investigating wild- 

 life problems in the National Forests, the National 

 Parks, and other public lands used so extensively 

 by persons seeking recreation. 



The principal wildlife research stations are the 

 Patuxent Wildlife Research Center near Laurel, Mary- 

 land, and the Wildlife Research Center, at Denver, 

 Colorado. Numerous investigations are being under- 

 taken by cooperative wildlife research units located 

 in sixteen States, including Alaska. These units 

 make important contributions in the training of 

 professional wildlife managers and in conservation- 

 education work which leads to greater appreciation 

 and better use of our wildlife and other natural 

 resources. In addition, the Bureau working with 

 various State fish and game departments studies 

 the suitability of introducing certain game birds 

 and animals into areas of this country that are 

 deficient in game. 



Wildlife research is not limited to migratory 

 species of birds or animals. Federal laws place 

 definite responsibility on the Bureau to conduct 

 investigations on resident big and small game ani- 

 mals, nongame birds, rodents, and other animals, 

 including the sea otter, walrus, and polar bear. 



Law Enforcement and Game Management 



One of the primary functions of the Bureau is 

 enforcement of the various Federal statutes and 

 regulations enacted for the protection and conserva- 

 tion of wild birds, mammals, and fish.
