Project description

This project is Task #7 of SANDAG contract number 5004388: Rare Butterfly Management and Conservation Planning. A summary of this task is provided below. Surveys for Harbison’s dun skipper adults were conducted to assess year to year variation in population size. Field visits were used to document use including plants used for nectar sources, as well as obtain non-lethal genetic samples.
