and:
• Less than 1/2 use bird info “most days”
Which factors are extremely important in conservation decisions?
Over 1/3 said:
• Bird population trends (both current and predicted)

THE PAST: History of Bird Declines
• What factors contributed to their decline?• To their recovery?
What are the types and distributions of habitats in California?
How important are these different habitat types to biodiversity?
“It would be beneficial to have a GIS database showing types and distributions of natural communities and habitats in CA.”
This would be driven by soils and hydrology.”
Comments from Survey Takers
What are the habitat requirements to maintain, enhance or restore avian biodiversity over different scales?
“I work in a small park. What is the minimum habitat patch size that will
support breeding of native birds?”
How do birds respond to habitat restoration?
• How do different species respond to RIPARIAN restoration in COASTAL CA?• How do bird populations, distributions and species richness change as a result of different FOREST treatments?
What protocols should I use to measure habitat enhancement?
