Candidate Species

General Status Assessment Procedure

Collect, review, and synthesize the existing published and unpublished material on the taxon. Contacts should be made with other Federal agencies, other Service offices and regions, state nongame and Heritage programs, tribal conservation agencies, conservation organizations (e.g. The Nature Conservancy), researchers, and other knowledgeable individuals to obtain a comprehensive and current picture of the taxon. Foreign data must be included for plants and invertebrate species, and is highly recommended for vertebrates, as well. Arrangements should be made with these sources to obtain new data that subsequently become available.

Because the Service can list Distinct Population Segments (DPSs) of vertebrate taxa, the SAR author should consider whether the SAR should assess the conservation status and threats to such geographically delimited subsets of the larger taxon. If initial review of the data indicate that a DPS-level evaluation might be needed, contact the Service to discuss this further.

Draft status assessment reports should be provided to the Service for early review to ensure that all important aspects are adequately covered. The Service will provide the draft to the Regional Office Listing Coordinator, the Regional Nongame Migratory Bird Coordinator if the assessment covers an avian species, or to the Regional Fisheries Resources Team Leader for fish or freshwater mussel species.

An advanced draft of the status assessment report should be sent to the principal data contributors for review, to ensure that their data and recommendations have been correctly interpreted. They should clearly understand that they are reviewing a draft document that is not intended for further distribution.

Completed status assessment reports will become public documents. As such they should contain primarily data and data analysis, as well as recommendations for conservation management, additional research, and improving the assessment. However, recommendations concerning elevation to candidate species status, listing, and critical habitat designation should not be contained in the SAR. The decision on whether to elevate a species to candidate status is made by the Service.

Content and Format Guidelines

Include in the Status Assessment Report:

Title Page - Include the common and scientific name, the geographic area covered, the author's name and office address, and the date of completion.

 

Disclaimer - This paragraph should be included near the front of all status assessment reports that are done, or contracted, by Region 3 for species having the potential for being listed as threatened or endangered:

This document is a compilation of biological data and a description of past, present, and likely future threats to [species common & scientific name]. It does not represent a decision by the U.S. Fish and Wildlife Service (Service) on whether this taxon should be designated as a candidate species for listing as threatened or endangered under the Federal Endangered Species Act. That decision will be made by the Service after reviewing this document; other relevant biological and threat data not included herein; and all relevant laws, regulations, and policies. The result of the decision will be posted on the Service's Region 3 Web site (refer to: http://www.fws.gov/midwest/eco_serv/soc/index.html). If designated as a candidate species, the taxon will subsequently be added to the Service's candidate species list that is periodically published in the Federal Register and posted on the World Wide Web (refer to: http://www.fws.gov/endangered/candidates/index.html). Even if the taxon does not warrant candidate status it should benefit from the conservation recommendations that are contained in this document.

 

1. Common Name (and other common names)

 

2. Scientific Name used in Federal Register (and other scientific names)

 

3. Controversial or unsettled taxonomic issues - Provide details, as taxonomic problems may preclude listing.

 

4. Physical description of the taxon - In addition to the technical description of the taxon, provide a summary of the key characteristics that a biologist (not necessarily a specialist in this taxon) can use to identify individuals of the taxon. A drawing or photo is beneficial.

 

5. Summary of (a) biology and natural history and (b) habitat requirements of the taxon - Include such things as territory size, site fidelity, reproduction, mortality, longevity, and seasonal habitat usage.

 

6. Current and historical range - Include significant breeding, migration, and wintering areas.

 

7. Current and historical population and productivity estimates & trends, broken out by state and province, and for individual local populations, if possible. It is important to distinguish between current (say within the last 10 years) and historical trends; historical trends provide background and perspective, while current trends provide the evidence that listing is warranted or unwarranted. The "ideal" is to describe the current trend (and threats, see below) for each known population unit across the entire range; get as close to the ideal as the data allow.

 

8. Summary of status and threats, organized by the five listing factors shown below. Explain the links between the threats and the taxon's decline; use specific examples. For past and on-going threats, document the extent of declines at specific locations and provide evidence of the causes. For anticipated future threats, assess the likelihood that a site or population will actually be affected, and describe the evidence leading to that conclusion. Use wording that can be directly incorporated into a listing proposal. As with population trends, the recent and on-going threats are more germane to a listing decision than are past or anticipated future threats.

A. The present or threatened destruction, modification, or curtailment of its habitat or range.

B. Overutilization for commercial, recreational, scientific, or educational purposes.

C. Disease or predation.

D. The inadequacy of existing regulatory mechanisms.

E. Other natural or manmade factors affecting its continued existence.

 

9. Current protective status under state/provincial/tribal/Federal laws and regulations.

 

10. Summary of land ownership and existing habitat protection for each population. This summary can be restricted to the most important populations if there are many. If landowners are identified, the addresses and phone numbers of private owners should only appear in an appendix so they can be easily removed from the main document.

 

11. Past and current (and anticipated) conservation activities undertaken for the benefit of the species or its habitat. What has been (is expected to be) the result?

 

12. Management actions (species, habitat, or people management) needed...

 

a. to preclude the need for listing as endangered or threatened;

b. to bring about recovery, if listed.

 

This section should contain sufficiently detailed and comprehensive management recommendations so that they can be promptly undertaken if listing is not recommended or not immediately pursued due to low listing priority. Alternatively, they can become the basis for a recovery outline if the taxon is listed. The actions should be prioritized.

 

13. Research, surveys, and monitoring needed...

 

a. to complete the status assessment and allow for an informed listing decision; include recommendations on surveying and monitoring protocols, if appropriate;

 

b. to bring about recovery, if listed.

 

These needs should be prioritized.

 

14. List of references used in completing the status assessment, including personal communications and "gray literature"

 

15. Name and office of preparer(s) and the date prepared

 

16. List of primary individuals contacted, including addresses and phone/fax numbers. Add this list as an appendix so it readily can be removed to comply with the Privacy Act in the event the status assessment is distributed outside the Service.

 

17. Site specific location information should be attached as a separate appendix so this information can be easily removed if the document is distributed outside of the Service. The inclusion of maps is strongly encouraged.

 

18. Copies of the relevant parts of all important references should be provided.
