1. Problem Statement What is the habitat status of the endangered Bay Checkerspot Butterfly in the Bay Area?

2. Questions To Be Examined Where do Bay Checkerspots live? Is any of their habitat protected? Might highway pollution effect their habitat? What pressure do they face from human habitation?

3. Butterfly data Parks Roads Census Data Spatial Query Parks that intersect butterfly habitat 1500m highway pollution buffer around habitat Major highways Population of census blocks touching habitat Spatial Query Attribute Query Spatial Query Project Flow Chart

9. Further Study Pollution levels vs. grassland health and butterfly population levels (over time) Detailed land use status of habitat areas Are there other similar serpentine grasslands around the Bay Area? Status? Do any other endangered species depend on the serpentine grasslands?
