Individual Management Plan Updates

When the Suisun Marsh plan was certified in 1977, it required an individual management plan (IMP) for each private duck club. The IMPs were originally developed by the U.S. Department of Agricultural Soil Conservation Service and certified by the San Francisco Bay Conservation and Development Commission (BCDC) in 1984. The original IMPs were created to provide managed wetlands water management guidelines for waterfowl food crop production and habitat management. These Plans had not been updated for over 35 years and lacked flexibility for adaptive habitat management, changes in environmental and regulatory constraints, and did not provide detailed background resources for landowner to reference.

The 2021 update of the Individual Ownership Adaptive Habitat Management Plans (IOAHMPs) provides a more flexible and practical framework for landowner’s wetland management and incorporates new science that has been developed over the past 35 years. Additionally, the 2021 IOAHMPs can readily be updated as club improvements occur, or future regulatory and environmental conditions change. The goal of the 2021 IOAHMP is to provide a managed wetland landowner with an overview describing existing conditions, operations, and guidance to support a diversity of waterfowl and wildlife habitats. The Plan includes a conservation map, soils map, elevation model, summary of water control structures, analysis of the water management program, and evaluation of the current conditions of levees, ditches, and water control structures.


Plan Example and Supporting Documentation

Suisun Resource Conservation District Board of Directors held a special meeting to conduct a public hearing on April 14, 2021 regarding an Amendment to SRCD’s component of the Suisun Marsh Local Protection Program (LPP). The public hearing was continued on August 11, 2021 where the Board adopted SRCD’s Amendment to the LPP consisting of 124 updated IOAHMPs. These 124 updated IOAHMPs were certified by BCDC on March 17, 2022. A management plan for the SRCD owned property, Lower Joice Island, is linked below as an example.
