This Natural Resources Management Plan provides the vision that guides future decisions for the Modini Ingalls Ecological Preserve (MIEP). Current management practices and an access policy are outlined. Available information on the natural resources of MIEP and threats to those resources are identified, along with on‐going and recommended projects. Finally, relevant documents are listed.

Modini Ingalls Ecological Preserve Natural Resources Management Plan

Conservation, management, and protection of harbor seats come under the purview of the Marine Mammal Protection Act (MMPA) of 1972 (Public Law 92-522). A primary directive of the MMPA is to protect marine mammal stocks from declining below their optimum sustainable population. To fulfill this directive in California, the California Department of Fish and Game (CDFG), in cooperation with the National Marine Fisheries Service (NMFS), has been conducting annual, state-wide, aerial surveys of harbor seals to assess the status of the population.

Audubon Canyon Ranch created a database, preliminary inventory, and report of the selected vertebrates of Modini-Ingalls Ecological Preserve, with species profiles, status assessments, and management objectives. Amphibians as a group have experienced declines in recent decades even in protected areas. Jim and Shirley Modini have long had a keen interest in the large mammals and birds of the ranch and as such have worked to document and invite others to document the presence of those animals. In contrast, the amphibians of the ranch are relatively unknown.
