The underlying policy of the Biological Survey with regard to injurious
species of wild animals has been and will continue to be one of control
rather than complete eradication. The bureau is not embarked upon a
general extermination program, but with every proper consideration
for conservation interests, it has as its objective in this field the
adequate local control of injurious mammals, so that the burdensome
losses suffered by farmers and stock raisers may be reduced to the
minimum and beneficial forms of wild life protected from undue
destruction by their natural enemies. Though in some cases this may
mean local eradication of harmful forms, it will not result in the
general extermination of any species.
