Monthly CNDDB Data Download
The CNDDB and accompanying GIS data are updated and processed monthly for distribution to subscribers. The Spotted Owl Observations Database is continually updated and processed periodically for distribution to subscribers. All CNDDB subscribers may download these updates or they may choose to receive a CNDDB RareFind compact disc (CD) in the mail every six months. Access to the download site is password controlled; see below for password information. CNDDB and Spotted Owl dataset components have been compressed into separate, self-executing files. Subscribers with computers running Windows® may use these files to update their CNDDB and Spotted Owl data.
*** IMPORTANT — PLEASE READ ***
Data updates and CNDDB password changes will occur every month on the first Tuesday of the month or the next business day if the Tuesday is a holiday. If you are a subscriber and need a RareFind CD, please contact BDB Information Services at (916) 324-3812.
