资源简介:
80 100 square meter plots located randomly throughout the uplands. were sampled similarly to the riparian sampling. GIS was used to identify latitude and longitude for each plot, and plots were located in the field using GPS. In each 100 square meter plot, all trees greater than or equal to 2.5 cm diameter at breast height (DBH) were identified to species and measured. All stems less than 2..5 cm DBH and greater than or equal to 1 m in height were counted. Four 1 square meter plots were established around the plot center, where percent cover of herbaceous species and species of woody seedlings were estimated using a 1 square meter frame divided into a grid of 100 10 square meter cells.
