Research (by others) on CNLM Preserves
Information for Researchers
We encourage and facilitate research (e.g., monitoring, mapping, collecting samples) by external researchers on CNLM preserves if the research:
- Poses no appreciable risk to the species, biological processes, or abiotic environment;
- Will result in information that contributes to effective conservation of CNLM preserves or other natural areas;
- Does not require excessive CNLM oversight or other CNLM resources
Because of the large number of CNLM preserves, researchers may find it helpful to review our species and habitat links or use our search functions.
Furthermore, since our preserves do harbor state and/or federally protected species, we take precautions to manage the risk to these species from any onsite (including research) activity very seriously. During the initial consideration of proposed research activity, we establish the objectives and methods, assist the researcher in finding appropriate sites within the identified preserve, recommend additional/ alternative preserves, discuss the sensitivity of onsite biological resources, and coordinate research projects to avoid conflicts with conservation values, stewardship activities or other ongoing research projects. Once we have determined that the proposed research is acceptable, we provide further information on site characteristics and access conditions, as appropriate.
We require researchers to limit CNLM liability, include acknowledgement of CNLM’s assistance in any reports/publications, and provide copies of related reports and publications for our records. These requirements are described in our ‘Site Access for Research Agreement’ (SARA)—a legal agreement that we have developed for this purpose. An appropriate research representative is required to sign this agreement before research commences on the preserve. Although the agreement is prepared as quickly as possible by CNLM, researchers should begin the agreement process at least two months prior to the commencement of research (to provide time for review by their institution, agency, or company, if applicable). CNLM does not require a fee for consultation related to the research or administration of the agreement as long as there is no for-profit interest involved (CNLM retains the right to review and change this policy in the future).
Investigators proposing to conduct research on listed (state or federal) species are required to obtain appropriate permits from the U.S. Fish and Wildlife Service and/or the California Department of Fish and Wildlife. Proof of permits are required prior to initiating any research on CNLM preserves.
