Methods

A prescribed burning program was initiated at CCESR in 1964 to restore and maintain oak savanna and woodland vegetation and to test the effectiveness of different prescribed burning treatments. An area of about 210 hectares was divided into 14 management units of 2.4 to 30 hectares each. Each unit was assigned to one of seven burn frequency treatments. ranging from annual burns to complete fire exclusion. which are shown in the following table _____ shrube133 - Shrub SurveySampling: Shrubs. seedlings. and saplingsShrub and seedling stem densities were sampled within a circular quadrat with 1-meter radius around each of the 24 sample points on the plot. We counted and recorded all woody stems by species at each point. In some cases. species with large local densities (e.g. Parthenocissus vitacea and Rhus radicans) were subsampled within 1 or 2 of the 4 quarters of the quadrat. On many of the plots. an additional 18 quadrats were sampled along 3 temporary 50-meter transect placed midway between each pair of permanent transects to produce a 6x7 grid of sample points. Note: This sampling method is different from the sampling method used in 1984 (point-quarter method. E015) and 1990 (6-10x10 meter subplots) so the data do not necessarily compare well. Saplings were recorded in a circular quadrat with 2-meter radius around each of the sample points (either 24 or 42) in the plot. We define saplings as individuals at least 1.5 meters tall and belonging to a tree species. Tree species were defined based on their maximum height and diameter growth potential at Cedar Creek. as determined by the tree surveys. Therefore. Amelanchier was considered a tree species. while chokecherry is classified as a shrub. Unit of abundance = IndCountInt, Unit of biomass = NA
