Yearly Fluctuations in Small Mammal Populations in a Southeastern United States Hardwood Forest

J. B. Gentry, Frank B. Golley & Michael H. Smith



A 5.8 hectare grid, consisting of 256 stations spaced 15 meters apart, was laid out in a mature cove hardwood forest near Aiken, South Carolina, USA.  Snap traps were used to remove animals from the grid.  The grid was trapped once each year from 1967-1970.  Emphasis was placed upon population levels, changes in species composition and habitat utilization of the small mammals.  Also considered were the effects of various environmental and treatment variables upon the final trapping results.  Population levels declined during the study.  Species composition did not remain the same over the four year period.  Prebaiting resulted in different removal rates.  Weather changes also influenced removal rates.
