Utilizing GIS to protect San Joaquin Kit Fox
• Answering ecological questions• Distribution and abundance• Home ranges
• Den and harassment avoidance• Improving methodologies for data collection and management
• Personal Geodatabases• Digital data collection
San Joaquin Kit Fox Scat Detection Surveys
“…estimates of population size using samples collected during annualNovember surveys indicated that ~33 individuals used the TSF over a 3 yr period.”
