Abstract
Analyzing Significant Natural Resource Areas in San Francisco ParksTrack: Ecology, Archaeology, and Conservation
Author(s): Jerry Davis, Debra Dwyer
Analysis of vegetation patterns and related features in San Francisco city parks presented several challenges. For management purposes, polygon samples were interpreted from aerial photography and field observation for dominant species cover. Field personnel used a systematic grid of point samples to collect quantitative species counts in plots. In order to make a complex data set requiring multiple linked databases accessible for analysis by conservation biologists, we developed a suite of Avenue scripts and dialog boxes. Analysis of native and non-native species richness will be used to prioritize restoration projects.
