GreenInfo Network has worked diligently over the past few years compiling all federal, state, county, city, special district, and non-profit protected areas into one database for the state of California. The California Protected Areas Database (CPAD) v1.2 now contains 48 million acres of land in 47,000 parcels from over 800 agencies. You can download and review the data by visiting www.calands.org. And, the data can be seen and queried in all their interactive glory at the ParkInfo and California Department of Parks and Recreation sites. Hats off to Jason Jones, CPAD Project Manager for all of his hard work!
