Dear Colleagues:

NOAA’s National Marine Fisheries Service (NMFS) Southwest Regional 
Office (SWR) is requesting assistance to collect information on pinniped 
haulout sites in California.

Documenting the location and seasonal use of pinniped haulout sites is 
important for managing activities that may impact pinnipeds and also for 
prioritizing research needs. NMFS-SWR, in collaboration with 
NMFS-Southwest Fisheries Science Center, has created an interactive GIS 
database that will provide a comprehensive inventory of pinniped haulout 
sites in California, based primarily from an extensive review of 
literature and from contributions from fellow researchers.

We are requesting assistance from pinniped researchers and others who 
are willing to share their information on pinniped haulout information 
in California. We understand the sensitivity of sharing data, but we 
want to make sure that the database incorporates both historical and 
current information on pinnipeds in California. Many pinniped surveys 
are conducted at the end of the breeding season when the majority of the 
animals are hauled out. Much can be inferred about dispersal of 
pinnipeds by comparing movement between the breeding and non-breeding 
seasons. However, less is known about dispersal within the breeding and 
particularly, during the non-breeding season. Thus, we hope that with 
your assistance, we will be able to compile year-round information on 
pinniped haulout sites in California. Primarily, we are interested in 
information (past and present) on: 1) species; 2) location (e.g., name 
of area and/or latitude/longitude); 3) counts; 4) date and time 
observed; 5) whether the area was/is used as a rookery or non-rookery; 
and 6) age class. Any other additional information would also be greatly 
appreciated. We also request that you include reference information, so 
that this may be included in the database as well.

Presently, the database will only be accessible to NMFS-SWR staff as we 
continue to develop this database and collect information. The 
information in the database will be evaluated and updated on an annual 
basis. In the future, we may want to make a restricted version of this 
database available to the public (likely to include the GIS map, species 
and location), but we will notify participating researchers prior to 

If you have information on pinniped haulout sites in California, but are 
unsure about disseminating data, please feel free to contact me so that 
we may discuss alternatives.

Please contact me with any questions.

Thank you in advance for your time.
