Spatial Analysis for Monitoring Forest Health
A plan for the spatial analysis for the sample design for the detection monitoring phase in the joint USDA Forest Service/EPA Forest Health Monitoring Program (FHM) in the United States is discussed. The spatial analysis procedure is intended to more quickly identify changes in forest health by providing increased sensitivity to localized changes. The procedure is initiated with a series of median sweeps along axes of interest. The resulting effect vectors and residuals are carried through time and analyzed for changes in trend. An example is given utilizing FHM data from New England.
