CNDDB Maps & Data
Online Map and Query Applications
CNDDB Quick Viewer
- Free. This map application provides access to the CNDDB data at the 7.5′ Quadrangle and County level. For more info on how to use the Quick Viewer, see the instructions. For more detailed information, a subscription is required.
CNDDB & Spotted Owl Data Viewer
- CNDDB subscription required. This robust map application provides access to the spatial detail of both the CNDDB data and Spotted Owl Observation data in the BIOS Data Viewer. Note that these are just two of the hundreds of data layers available in the BIOS Data Viewer; we have just pre-loaded these two data sets for your convenience. About the Spotted Owl Database
RareFind 4
-
CNDDB subscription required. RareFind 4 is an
Internet application that allows for more robust querying and reporting of the CNDDB data than the map viewer, but with no
direct map interface. We are currently working to enhance this application and connect it more directly with the map viewer.
Because it's an Internet application, RareFind 4 eliminates the need for the user to install the RareFind 3 application on their computer and download the updated CNDDB data every month for use with RareFind 3.
Data and RareFind 3
Monthly CNDDB Data
- CNDDB subscription required. Monthly CNDDB data updates for use in RareFind 3 or with GIS software. The Spotted Owl Database is also available here.
RareFind 3
-
CNDDB subscription required. RareFind 3 is a
desktop Windows-based application that allows for robust querying of statewide data on rare species and natural community locations.
While RareFind 3 is still a very functional application, we are migrating this functionality to our online RareFind 4 application.
