In 2019, the North Coast Redwoods District of California State Parks began to implement the Humboldt marten population inventory and monitoring protocol (Slauson and Moriarty 2014) in the Redwood National and State Parks (RNSP) complex with the goal on conducting a complete survey of all park units in the complex within 4 years. In 2019, Del Norte Coast Redwoods State Park and the National Park units adjacent to it were surveyed and Humboldt martens were detected at only one of 36 survey units (Slauson 2021). This single detection occurred on the eastern edge of the park in serpentine forest habitat. In 2020, Prairie Creek Redwoods State Park and the adjacent portions of Redwood National Park were surveyed and martens were detected at 12 (31%) of 39 surveys units (Slauson 2021). In 2021, surveys were conducted in Jedediah Smith Redwoods State Park and in 2022, the final portion of Redwood National Park which included most of the Redwood Creek watershed in the southern end of the Park was surveyed. This report covers the final two years (2021 and 2022) of survey efforts needed to complete the first systematic survey inventory of martens and their predators across all the park units in the RNSP complex.
