Data for: A Bayesian analysis of topographic influences on the presence and severity of beech bark disease
Description
These data were collected over 5 years from the Lewis Deane Nature Preserve, an 85 acre preserve at the northern end of the Taconic Mountains in Poultney, Vermont, USA. A total of 210 trees were sampled. Recorded variables are as follows: -Time indicates the number of years since the start of the study at the time of sampling. -Tree records the tree ID number. -Rank is the disease rank of the tree using the ranking system described in our paper (1 ≤ rank ≤ 5). -Binary Rank indicates a tree being measured as healthy (0) or infected (1). -Elevation = height above sea level in meters. -Slope = slope in degrees. -Aspect = change in aspect in degrees clockwise from North (e.g. 90 = East). -Curvature = curvature of terrain in z-units. -Weighted Distance (units are 1/[meters squared]) is calculated as the sum of all infected trees weighted by the inverse square distance ([distance]^-2) to the tree of interest. -Distance to Nearest is the distance in meters to the nearest infected tree. -DBH = tree diameter at breast height and is in centimeters. -Latitude and Longitude are UTM coordinates.
