Implementation: Redwood Mountain Grove and Adjacent Proposed Fisher Critical Habitat Corridor


Field surveys were completed in 2022 and 2023 in Redwood Mountain Grove and in an adjacent proposed fisher critical habitat corridor. The data from these surveys indicate that natural regeneration is likely insufficient to support a self-sustaining population of sequoias within Redwood Mountain Grove. Regeneration is also very low in the adjacent proposed fisher critical habitat corridor.

Field data from 2022 and 2023 are available for download below. This data was collected under a field study that was designed and implemented by the National Park Service (NPS), the United States Geological Survey (USGS), United States Forest Service (USFS), and the University of California, Davis. The NPS therefore requests that any use of this data for publication rely on the full data set (i.e., use of a subset of this data is not seen to be appropriate or in keeping with the methods of data collection) and that any user of this data for publication communicate in advance with the scientists who collected the data. The contact information for these scientists can be obtained by emailing SEKI_Superintendent@nps.gov.

Soderberg et al. 2023, in review, is also available for download below. This paper provides an analysis of the attached data, showing that the 2022 regeneration data has a 1.1% probability of the seedling densities being equivalent to those the second year after fire (see page 15).

Given the above, the NPS developed and approved a planting plan for Redwood Mountain Grove and the adjacent proposed fisher critical habitat corridor in early fall 2023 and initiated a planting effort on October 17, 2023. Planting was performed by contractors, youth corps, and partners using hand tools and overseen by NPS ecologists and biological science technicians. The planting plan and approval documents are available below as well as several maps that show the grove boundary, extent of the planted area, as well as areas not planted due to adequate natural regeneration. Please note: exact boundaries of planted and unplanted areas are approximate in these maps due to limitations in accuracy of hand-held units carried by planters; areas indicated as planted on the maps may have smaller areas within them that were not planted but are not shown on the maps.
