The effect of grazing on small mammals in California annual rangeland.

When pasture land, is grazed by cattle the composition of the herbaceous vegetation is changed from that of the ungrazed state and the ecology of the pastoral habitat will be variously affected. The object of this investigation was to examine the distribution of small mammal populations on two areas, one moderatly grazed and the other not grazed, to determine the effect of grazing on small mammal distribution. The importance of small mammal habitat preference was also to be determined.
