Small mammal disturbance data for Martinelli slope, 1989 - 1992.

Permanent plots were established on the Martinelli slope in 1987. The 25 plots are organized in a Latin square design consisting of 5 rows and 5 columns. Plots are numbered according to row and column, beginning with 11 at the northwest corner of the grid. Plot 55 is located at the southeast corner of the grid. Each plot has dimensions of 1.5 m x 2.0 m. The corners of each plot are marked with rebar stakes. Each plot is divided into an evenly spaced grid consisting of 15 x 20 points on each side, for a total of 300 points, with each point situated 10 cm from its nearest neighbors. Small mammal disturbances were classified each year at each point where such disturbances occurred. The point-quadrat method used was similar to that described by Auerbach (1992): The point-quadrat method was used for estimating canopy stratification and plant cover. Aluminum point-quadrat frames were 3m^2 in size, with double-layer filament spaced 10 cm apart to make a 145 x 195 cm grid for a total of 300 sample points per plot. If small mammal disturbances were present at a point, those disturbances were classified as indicated in the comments section.
