Monitoring Pine Pitch Canker With GIS Track: Forestry, Wildlife, and Fisheries Management Author(s): David Yun, Douglas Piirto, Walter Mark Pitch canker is a disease caused by a fungus (Fusarium circinatum) in most coniferous tree species. Several pitch canker research projects were performed on Monterey pine (Pinus radiata) stand at Swanton Pacific Ranch, Davenport, California. GIS was used to map various survey transects, sampling plots, individual sample trees, and planted seedlings. ArcGIS allowed various data in different coordinate system, datum, and units to be managed easily. Using ArcGIS, an Excel spreadsheet, and simple trigonometry, most of the collected data were either mapped directly or linked to existing GIS layers. Although statistical analysis was done on Minitab, displaying the pitch canker activities were all done in ArcGIS Desktop and ArcView 3.3. Pitch canker rating data collected from 1999 to 2001 implied that there is a decrease in pitch canker activity at the study site. Showing the map that supports statistical analysis results had a great impact in the research presentation.
