Over 10 years of mountain lion (Puma concolor) geospatial data was integrated into a personal geodatabase using Microsoft Access. Data validation was used in the database to ensure consistency of the records, which was the major problem prior to the database being implemented. The final map file pictured above represents the movement patterns of six mountain lion individuals for 2010 in the Santa Ana Mountains of Southern California. Layers added to the map include road networks, incorporated areas, unincorporated areas, national hydrology, 1/3 arc second hill-shaded DEM, forest boundaries, and individual mountain lion track data. The final map was produced in ArcGIS 10, with subsequent fine tuning done with Avenza MapPublisher within Adobe Illustrator.
