If you are a CNDDB subscriber, you are likely very familiar with BIOS 5 as the quickest online access to CNDDB data, as well as other datasets in the CDFW BIOS collection. We are happy to announce the release of BIOS 6. This next version of the CDFW BIOS viewer is built on the latest Esri ArcGIS JavaScript API and will eventually replace the current BIOS 5 viewer.

During the transition, both viewers will be available for a short time. We encourage you to start using the new viewer for your work now to familiarize yourself with content before the old viewer is no longer available. Most major functionalities are preserved from BIOS 5 to 6. You will be able to move your selections between BIOS 6 and RareFind. In RareFind, the BIOS tab will have a radio button in which you can choose to open BIOS 5 or BIOS 6.

We have provided a full user guide (PDF) for you, as well as a condensed version of basic functions to help you get started (PDF). If you have questions and comments about BIOS 6, you can submit them to
