Willow dock is a perennial herb usually found in wetlands, and occasionally in non-wetland areas such as yellow pine forest, foothill woodlands, chaparral, and valley grassland vegetation communities. It flowers April-June and its only occurrence within the County was documented in the Ventura USGS quadrangle map. This species was the only species out of the seven nominated species that was added to the 2023-2024 LIS Plant List.

What’s New in the Locally Important Species Program 2023-2024!
Read about updates regarding the results of the 2023-2024 annual review, new information provided in the Locally Important Species (LIS) lists, a new submission/removal form for multiple LIS plant species, and the introduction of a plant species watch list.
Ventura County Locally Important Species List 2023-2024 Annual Review
In 2023-2024, there were no submissions for the Locally Important Species (LIS) Animal List. However, during a comprehensive review conducted with the help of our Civic Spark Fellow, Kylie Speth, three species were removed from the LIS animal list because of their listing status by the California Department of Fish and Wildlife (CDFW) – the Pacific Lamprey, Entosphenus tridentatus; California Glossy Snake, Arizona elegans occidentalis; and the Mt. Pinos lodgepole chipmunk, Neotamias speciosus callipeplus. The 2023-2024 LIS Animal List now contains 11 species.
Seven submissions were reviewed by the LIS Plant Committee, with one species, Rumex transitorius or willow dock added for the year (see photo above). There were initially 10 formal submissions for removal from the LIS plant list, but by the end of the comprehensive LIS lists review, a total of 64 plant species were removed due to nominations, federal/ state listing status, and other various factors. The 2023-2024 LIS plant list now contains 235 species from the previous list of 299 species.
Release of the Updated 2023-2024 LIS Lists with New Fields and Formats
The LIS lists are now more user friendly for the California Environmental Quality Act (CEQA) biological assessments reports! All LIS lists contain additional life history information for each species to help streamline data needs for applicants and consultants. This data also includes the name of the United States Geological Survey (USGS) quadrangle map of where the species was documented in the county to help biologists know when these species need to be added to their assessment tables and to brush up on their LIS identification skills before those field surveys! The lists are available in excel format below.
New Excel File Species Data Submission Form Available!
For multiple species submissions, an excel format-based form is now available on the website under our update procedures section. All occurrence data still requires data from peer review publications or CDFW CNDDB occurrence records in the Rarefind viewer or herbarium records an approved iNaturalist record within the CDFW CNDDB iNaturalist program page that has been screened by CDFW biologists to be submitted as separate documentation.
Locally Important Species Watch List
Some years the LIS Plant Review Committee finds there are plant species that did not have enough reliable data or other information available for them to be placed on the LIS list. To increase awareness about those species when observational and specimen collection data is lacking, the County provides for use by the approved Qualified Biologists and other trained botanists, a “Watch List” of these species. See the Watch List Species section below that explains what the watch list is and it’s voluntarily use outside of the LIS program and CEQA review.
Plant Collection Permits
To help promote and encourage the collection of more data on the status of LIS and other rare plants within Ventura County, the County’s approved Qualified Biologists who carry out the primary targeted surveys for LIS are encouraged to obtain a plant voucher collecting permit from the California Department of Fish and Wildlife. Local botanist’s, members of the California Native Plant Society (CNPS) local chapter , and CNPS certified botanists are encouraged to obtain this permit. If new occurrences are officially confirmed in the County, this allows for species to be documented and if the criteria are met, officially removed from the County’s LIS list.
Ventura County’s Locally Important Species Program

There are 2 confirmed occurrences of turbinate sand-verbena in Ventura County.Ventura County’s unique location on the California coastline spans one of only two of the east-west transverse mountain ranges in North America whose biogeography serves as a transition zone between California’s Central and South Coast regions. Ventura is an area that has experienced considerable geologic and climatic changes that have influenced the region during its recent prehistory. As an example, these environmental conditions and geography have created a variety of localized “microclimates” and habitat conditions where several small “relict” populations of plant taxa persist throughout areas of the County, which were presumably more widespread in the past . These factors contribute to surprising flora diversity, where the County contains 25% of all native plant taxa known to occur in California but represents only 1% of its landmass (Magney 2023).
In the late 1990s and early 2000s, local and regional biological experts recognized the unique environmental conditions and diversity present in the Ventura County and worked with the County’s Planning Staff and local leaders to establish protections for the County’s animal and plant species, that were associated with limited, localized, and/or rare habitat types and environmental conditions. The result of those efforts resulted in language within the County’s 1988-2020 General Plan regarding the preservation and protection of Locally Important Species and Natural Communities (Section 1.5-Biological Resources, Goal 1.5.1).
Ventura County’s 2040 General Plan retains those goals and policies today, where Locally Important Species are identified as significant biological resources to be protected from incompatible land uses and development (see Goal COS-1 and Policy 1.1). To ensure consistent identification of Locally Important Species, the listing criteria and process are established in the Biological Resources Section of the Initial Study Assessment Guidelines (ISAGs). Together the General Plan and ISAGs require that the project’s potential impacts to Locally Important Species be included in all biological resource assessments conducted by County approved qualified biologists for California Environmental Quality Act (CEQA) review.
2023-2024 Locally Important Species Lists
CEQA requires that a proposed development evaluate all potential environmental impacts, which includes impacts on any federal, state, or locally designated special status species under the Act, which includes the County’s LIS. These species are evaluated under the County’s ISAGS as potential special status species that may occur on the project site and included in the initial studies or biological assessments conducted on the project site prior to the ISAG’s analysis.

Locally Important Species Criteria and List Update Procedures
The Planning Division periodically reviews and updates the LIS List. The Planning Division maintains a list of plants and animals that meet the criteria for LIS and updates the list on an annual basis if changes are warranted.
Proposals for additions to or removals from the LIS List is conducted by filling out a Data Form below and submitting it to the Planning Division with information that supports the submitted statements about a species’ populations, range, important habitats, and status.
- Animal Data Form
- Plant Data Form
- Excel Data Form (This excel form is for the submission/removal of multiple plant species).
Important Notes for Submissions:
Please include citations for sources of information that support statements about a species’ populations, range, important habitats, and status. Species Data Forms that do not provide citations or supporting documentation will not be considered by the reviewers.
A) All species occurrence data must include one of the following types of documentation: 1) published in a peer review journal or Consortium of California Herbaria, or historic county records/collections; 2) For animal occurrences or a new plant occurrence not yet documented in the Consortium of California Herbaria, provide a documented California Natural Diversity Database (CNDDB) PDF report CNDDB Field Survey Form, or iNaturalist verification via CDFW CNDDB program page to be submitted as separate documentation. The Planning Division is encouraging professional botanists to get a plant voucher collecting permit from the California Department of Fish and Wildlife so that species on the LIS or Watch list can be submitted to an approved herbaria. This allows for species to be officially removed from the County’s LIS list when new occurrences are officially confirmed in the unincorporated areas of the county or for us to learn more about our watch list species.
B) Species considered extirpated will not be considered for listing on the County’s LIS but may be considered by the Review Committee for addition the County’s Watch List.
C) All species with occurrence data within Ventura County, except the Channel Islands will be considered.

Locally Important Species Watch List
The “Watch List” is meant to serve as a field reference for qualified practitioners for potential rare species when observational and specimen collection data is lacking. If these species are encountered in the field, the botany field/community needs a herbarium specimen to be collected and submitted, because not enough is known about the plant’s distribution, life history, or taxonomy in the county. The “Watch List” is posted to the County website and is shared with other organization’s websites such as the California Native Plant Society Channel Islands Chapter for informational purposes and is not part of the Locally Important Species List nor is it used for CEQA review purposes.
