What is the goal of the California Natural Diversity Database? Simply put, it is "a program that inventories the status and locations of rare plants and animals in California." On its page, visitors can look over a remarkable database of GIS-mapped locations, along with key facts about the database, a host of white papers, and information about its vegetation, classification, and mapping program. The Maps & Data area is a true find, as it contains interactive maps that offer visitors the ability to engage with data over time. Materials dating back to 2003 may be accessed here. Also, users can submit their own data to the database via the Submitting Data to CNDDB section of the site. Interested users can also sign up to receive updates about the site and its new additions.
