CONTROL FUNCTIONS OF THE BUREAU OF BIOLOGICAL SURVEY

The administration of wild life by the Bureau of Biological Survey

involves not only research into the habits, distribution, and

requirements of the varieties, and the conservation of fur, game,

insectivorous, and other valuable animals, but also the regulation

of activities of a limited number of certain species that seriously

interfere with the economic interests of man, and, in the case of some

of the larger predators, prey upon valuable game species.

The leadership of the Biological Survey in control operations during

the years since 1915 has been requested and encouraged by State and

other cooperating agencies. The funds made available from these sources

for expenditure under the direction of the district leaders of the

bureau have been far in excess of those provided for the purpose from

the National Treasury. The investigations of the food and other habits,

the geographic distribution, and the relationships of the wild birds

and mammals of the country (including rodents and predators) have been

carried on for almost half a century and provide the basis for the

control work recommended and prosecuted. Research along these lines is

being continued by scientifically trained men and will be expanded as

funds permit.

It is well for the conservation of the wild life of the country that

leadership in the control of injurious species has been delegated to

a governmental organization that is concerned with the welfare of the

various forms and with the administration of wild-life refuges, one

that is charged with the enforcement of wild-life conservation laws,

and one that recognizes the desirability of preserving representatives

of all forms of wild life on suitable areas.
