Research on CNLM Preserves

The Center for Natural Lands Management (CNLM) values science-based information in guiding management practices. CNLM preserves harbor endangered, threatened, and rare species, all of which are vulnerable to stochastic events. We strive to manage the native species so as to ensure even small populations have the best opportunity for longterm viability. Some ‘research' activities are typically undertaken by CNLM preserve managers. These include surveys of native species, habitat types, and exotic invasives; GIS mapping of various biological and geographic features; structured comparisons of weed control methods; and monitoring of listed species (or contracting for this activity if the preserve managers do not have the appropriate permit or time available).

We value the information associated with research by external researchers on our preserves, particularly when it has the potential to inform preserve management practices. Our review process ensures that methods are not only reasonable and appropriate for the preserve, but frequently can result in the improvement or expansion of the research proposal, based on the preserve manager's insights on the species and habitats involved. Early engagement between CNLM staff and researchers also helps to ensure that the resulting information will become a permanent record in CNLM's institutional memory and appropriately applied to preserve management.

Current Research by External Researchers
As of June 2008, there were 11 research projects in progress on CNLM preserves, with several others in review. As results become available, more information will be provided on these webpages.

Information for Researchers  
We encourage and facilitate research by external researchers on CNLM preserves when the research (a) poses no appreciable risk to the species, biological processes, or abiotic environment; (b) will result in information that contributes to effective conservation of CNLM preserves or other natural areas; and (c) does not require prohibitive oversight or contributions from CNLM. ‘Research' is interpreted as monitoring, mapping, making collections, or on-site research of any kind.

Because of the large number of CNLM preserves, researchers may find it helpful to use the ‘search' box to query for particular species or habitat types of interest.

Because our preserves harbor State and/or federally protected species, we take precautions to manage the risk to these species from any onsite (including research) activity. During the initial contact, we establish the objectives and methods of the proposed research, assist the researcher in finding appropriate sites within the identified preserve or recommend additional or alternative preserves, and discuss the sensitivity of onsite biological resources. We also coordinate research projects so as to avoid conflicts. Once we have determined that the research is acceptable, we provide further information on site characteristics and access conditions, as appropriate.

We require researchers to limit CNLM liability, provide acknowledgement of CNLM assistance in resulting reports and publications, and provide copies of related reports and publications. These requirements are described in our ‘Site Access for Research Agreement' (SARA)—a legal agreement that we have developed for this purpose. A suitable representative for the researcher signs this agreement before research commences on the preserve. Although the agreement is prepared as quickly as possible by CNLM, researchers should allow a month prior to the commencement of research so as to provide time for review by their institution, agency, or company (if applicable). At this time, no fee is imposed by CNLM for consultation for research and administration of the agreement, although that policy may be revisited pending review of CNLM expenditures on such activities.

Researchers proposing to conduct research on listed (State or federal) species are responsible for obtaining appropriate permits from the U.S. Fish and Wildlife Service and/or the California Department of Fish and Game. Researchers will be required to provide proof of permits prior to the conduct of research on CNLM preserves.
