Monitoring of subtidal fish and invertebrates inside and out of no-take safety zones at SAN clemente island, CA

Naval Auxiliary Landing Field San Clemente Island (SCI) is designated as an Area of Special Biological Significance and under Executive Order 13158, all Areas of Special Biological Significance were deemed National Marine Protected Areas. The Marine Life Protection Act Amendments of 2004 required the effectiveness of all National Marine Protected Areas, California State Marine Protected Areas, and Areas of Special Biological Significance to be reevaluated to design new Marine Protected Areas that together function as a statewide network. The 1999 and 2004 amendments of the Marine Life Protection Act (Chapter 10.5 of the California Fish and Game Code, §2850-2863) directed the state to reevaluate and redesign California's system of Marine Protected Areas and requires monitoring of those Marine Protected Areas. All of the Channel Islands, including SCI, were considered for designation of Marine Protected Areas.

In 2010, the U.S. Coast Guard (USCG) established permanent safety zones (Federal Register Vol. 75, No. 97) off the shore of SCI in order to conduct training essential to successfully accomplishing U.S. Navy missions relating to military operations and national security. The safety zones are intended to protect the public from hazardous, live-fire, and testing operations, and to ensure operations proceed as scheduled. With the establishment of safety zones, the Navy withdrew such areas from unrestricted public use in favor of utilizing these areas for military training.

To achieve compliance with the SCI Integrated Natural Resource Management Plan (INRMP), Executive Order 13158, and to avoid designation of a state Marine Protected Area, the SCI INRMP boundary was extended to align with the safety zone boundaries established by USCG. As agreed with the State and the INRMP, these safety zones act as defacto Marine Protected Areas and are monitored similarly to the South Coast Marine Protected Areas. In 2012/2013, baseline Remotely Operated Vehicle surveys and bathymetric mapping efforts were conducted at SCI to support safety zone monitoring.

The work under this proposed Cooperative Agreement will build on the baseline 2012/2013 Remotely Operated Vehicle surveys and 2019/2020 continued long-term monitoring efforts to continue to evaluate changes to fishes and invertebrates inside and outside no-take safety zones. The objective of this project is to continue long-term monitoring of fishes and invertebrates in order to evaluate the ecological changes within the SCI safety zones with a focus on evaluating differences between the no-take safety zones and those that are open to fishing consistent with the California Department of Fish and Wildlife Marine Protected Area Monitoring Action Plan (California Department of Fish and Wildlife and California Ocean Protection Council, 2018; https://www.wildlife.ca.gov/Conservation/Marine/MPAs/Management/Monitoring/Action-Plan).

Brief Description of the Anticipated Work:

This Cooperative Agreement includes three Base Tasks. The first base task is to conduct subtidal, imagery-based habitat surveys for fishes and selected invertebrates based on species observed in 2024/2025. The second base task is to conduct spatial analyses (including, but not limited to, habitat suitability models) on the fish and invertebrate data combined with existing bathymetric maps of the seafloor. The third base task is to develop a preliminary report with a summary of the surveys. The specific requirements for each Base Task are described below.

1. Survey Subtidal Habitat for Demersal Fishes and Invertebrates:

The Recipient shall conduct imagery-based subtidal surveys for fishes and selected invertebrates with protocols approved by the Cooperative Agreement Technical Representative (CATR). Surveys shall focus on, but are not limited to, species identified in the 2012 - 2015 and 2019/2020 Remotely Operated Vehicle surveys and to the best extent practicable sample at previously surveyed sites.

The Recipient shall be responsible for scheduling and coordinating field activities such as surveying with the CATR, and other necessary island personnel. The Recipient shall be responsible for providing information necessary to obtain security passes for all personnel and vehicles requiring access to the Navy installations at least one month prior to surveys. The Recipient shall submit the information necessary to obtain the security passes at least one month in advance of initial access. The CATR will assist in obtaining the security passes.

2. Conduct Comprehensive Spatial Analyses of Patterns in the Distribution of Demersal Fishes and Invertebrates:

The Recipient shall conduct comprehensive spatial analyses of imagery-derived data, combined with habitat classification maps of the subtidal environment. Analyses shall be conducted using the current best practices and the appropriate software for such analyses.

3. Draft and Final Technical Report:

The draft and final preliminary report shall be submitted in accordance with Section J. Submittals and Schedules. The report shall be in scientific format and include the following: 1) Title page showing title, date, cooperative agreement number, Pacific Fleet Representative and Cooperative Agreement Technical Representative contact information; 2) Sub-title page showing title, prepared by and for listings, date and recommended citation; 3) Table of contents; 4) Abstract or Executive Summary; 5) Introduction; 6) Methods; 7) Results; 8) Discussion; 9) Conclusions (to include synthesis with previous work and recommendations for future study); 10) Legible copies of the field notes, data forms and other information.
