The NRDB is a compilation of observations of flora and fauna made at open space and nature preserves in the greater San Francisco Bay Area. The database can be searched for available data on flora, mammals, birds, and reptiles-amphibians-fishes seen at one or more preserves.

Nomenclature Changes

This release of the NRDB has incorporated new flora nomenclature from the upcoming The Jepson Manual: Vascular Plants of California, Second Edition (referred to throughout as Jepson II). For more information, refer to the online version at

The nomenclature changes for Jepson II are extensive. We strongly encourage you to create new species lists to replace old ones. See Donít Forget Ö below to see simple ways to do so.

A pdf file of nomenclature changes for this and previous NRDB releases is available under the Nomenclature Changes tab.

New Preserves The following new preserves and data have been added to the NRDB:
  • Stafford Lake Park (flora, birds)
What Lists Have Been Updated? Bothin Marsh Open Space Preserve, Rush Creek Open Space Preserve. These two Marin County Preserves have been in the NRDB but without lists of flora. The flora lists have now been added.

There have been many other additions to the database, especially for flora in preserves in San Mateo County, thanks to the hard work of Toni Corelli. If you have an older list for any preserve in the NRDB, you should check to see if has been updated. How do you check if you need a new list? In the March 2008 release of the NRDB we added Last Update information to the Preserves table. You can see when the last changes were made to species lists for each preserve by selecting Preserves under the Reports tab on our home page at and reviewing the Last Update column. You can quickly determine if your existing checklist is up to date!
Don't Forget Checklist Search and Spreadsheet View

Checklist Search provides a simple and fast way to generate a pre-formatted checklist suitable for printing. Checklist Search is the first selection under the Searches menu. Use Advanced Search to generate checklists with custom formatting or contents.
