    The California Department of Fish and Wildlife (CDFW) has initiated a five-year species review (Species Review) for the state endangered Lake County stonecrop (Sedella leiocarpa) to inform the California Fish and Game Commission's decision on whether to retain or change the status of the species under the California Endangered Species Act (CESA). As part of this process, the CNDDB would like to encourage anyone who has observed Lake County stonecrop to submit their findings to us. People who have questions or comments about the review process should email our Native Plant Program. The deadline to submit data and comments is October 20, 2023, to allow us sufficient time for evaluation.

    Lake County stonecrop is an annual plant with only six known populations located approximately 10-24 km (6-15 mi) southwest of Clearlake, CA. This plant was originally listed as endangered and afforded protection under the California Endangered Species Act (CESA) in 1989 (Fish & G. Code, §2050 et seq.). The purpose of a Species Review is to use the best scientific information available to determine if the conditions that led to the original species listing are still present or have changed since listing, and recommend to retain or change the status of the species (Fish & G. Code, §§ 2072.3 & 2077). Process information, along with recently completed reviews, are available on our web page for Five-Year Reviews of Rare, Threatened and Endangered Species. Take of this species is prohibited without an appropriate permit for scientific, educational or management purposes. For more information on permitting, visit our CESA permits web page.

    We need your help in better understanding the endangered status of Lake County stonecrop. If you have ever found them in the wild, submit your findings to us through our Online Field Survey Form.

    Our barred owl datasets have been updated!

    Barred Owl Observations by PLSS Section [ds2873] is available to view and to download in the BIOS Viewer. This layer summarizes the information contained in the Barred Owl Observations Database and allows users to see PLSS sections containing barred owl detections as well as the first and last years owls were reported in those sections.

    Barred Owl Observations [ds8] is available in the BIOS Viewer for CNDDB subscribers. The barred owl database includes barred owl (Strix varia), Strix hybrid, and unknown Strix detections. This dataset is only available to view and download by CNDDB subscribers because it contains references to sensitive spotted owl locations. For site-specific inquiries, email

    Due to the varied nature of barred owl surveys, detections, and reporting in the state, these datasets may not fully represent the historical and current distribution of barred owls in California.

    For more information on barred owls in California, check out CDFW’s Barred Owl Threat web page.

    July 16 is World Snake Day, which offers no better opportunity to appreciate our scaly friends and the contributions our submitters have made to conserving this group of reptiles through their CNDDB observations. California is home to nearly 50 native snake species, and 16 are tracked through the CNDDB database. This beautiful red-diamond rattlesnake was found by Adam in the Jacumba Wilderness of Imperial County. As its name suggests, this species is identifiable by the color of its scales which can range in hues of pinkish-brown, red-orangey tan, or brick red. This snake can be found slithering in chaparral, woodland, and arid desert habitats through southwestern California to mid Baja. The red-diamond rattlesnake is a CDFW Species of Special Concern with 260 mapped occurrences throughout its California range. Thank you, Adam, for sharing this awesome photo! Happy World Snake Day everyone!
