Abstract During the spring of 1963 and 1964 an investigation of a small
mammal community was made in McDonald Forest, near Corvallis, Oregon.
The revised North American Census of Small Mammals procedure was
used, and from this census the species composition of the community
was determined. The relationships of several genera indicated a
social dominance within the community.
The population density remained rather constant over the two
year period, but the composition of this population varied a great
deal. Peromyscus and Sorex demonstrated a rather large increase
from 1963 to 1964, while Microtus and Eutamias numbers dropped.
The efficiency of this method was tested by trapping for four
additional days in the center of the circle after the regular
trapping period. This additional trapping demonstrated that the
animals with larger home ranges were completely removed, while
animals with small home ranges were still in the area.
