The California Department of Fish and Wildlife has initiated a five-year species review for the state threatened Mohave ground squirrel (Xerospermophilus mohavensis) 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 Mohave ground squirrel to submit their findings to us. People who have questions or comments about the review process should email the Wildlife Diversity Program and include “Mohave ground squirrel” in the subject line. The deadline to submit data and comments is October 28, 2023, to allow sufficient time for evaluation.

The Mohave ground squirrel is a small rodent endemic to the western Mojave Desert of California and has one of the smallest geographic ranges of any North American ground squirrel. It was listed under the original enactment of CESA in 1971. The purpose of a five-year 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 retaining or changing 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.

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 owlobs@wildlife.ca.gov

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!

The CNDDB is ready for a renovation. Much of 2022 was spent preparing for upgrades to our program. This will be a multi-year process. While our users may not see much change in 2023, be aware that we've been working hard behind-the-scenes to modernize and streamline our data processing. Things are under construction! In the meantime, here is a summary of what we have done in 2022, and our goals for 2023:

2022 By the Numbers

• 100,800 total occurrences in CNDDB
  • 500 new occurrences mapped
  • 500 occurrences updated
• 279,300 total source records in CNDDB
  • 6,900 sources added (3,500 records added through the Online Field Survey Form)
  • 2,900 sources processed
• 3,700 total spotted owl records
  • 700 CSO and 3,000 NSO records added
  • 1,300 spotted owl sites updated
  • 317 activity centers updated
  • 27 activity centers added

2022 Accomplishments

• Created new training materials
  • New video that goes over common ways users may access CNDDB and spotted owl data using BIOS and RareFind
  • Updated user guides for the launch of BIOS 6
• CNDDB modernization (ongoing)
  • Plan for new ways CNDDB systems and processes can better serve all interested parties
  • Conducted user survey; results of the survey that you all provided input for directly influenced our assessment of the CNDDB system, tools, and products.
  • Continued the Project Approval Lifecycle (PAL) process for modernizing CNDDB
• Welcomed a new botanist to the program

Goals for 2023

• CNDDB modernization
  • CNDDB will be laser focused on finishing the PAL process for our modernization effort, quickly moving to the implementation phase of the project. For that reason, users may see moments of inactivity in our regular core duties in 2023.
  • Expand CNDDB staff resources to the extent possible
  • Continue CNDDB outreach through our blog or social media

While we are juggling all these goals in 2023, you may see a lull in our data processing. Fortunately, we currently have a way to share data to our subscribers prior to CNDDB processing. Data submitted through the Online Field Survey Form is shared with our users the next month. Therefore, if you detected CNDDB-tracked species while out in the field, please remember to submit your data through our online form. Obtaining quality data is a vital first step to protecting California’s rarest natural resources, and you can help make that happen. As always, you can contact us at any time with suggestions or questions by emailing CNDDB@wildlife.ca.gov. Wishing everyone a wonderful 2023!
