Research
Natural Areas
Researc h Natural Areas include relatively undisturbed areas of the national forest that form a
long-term network of ecological reserves designated for research, education, and the
maintenance of biodiversity. This designation applies to both established and proposed research
natura l areas.
Research Natural Areas are selected to preserve a spectrum
of relatively pristine areas that
represent a wide range of natural
variability within important natural ecosystems and
environments, and areas that
have unique characteristics of scientific importance. Research
Natural Areas are also selected for one or more of the following reasons:
• To serve as reference areas for evaluating the range of natural variability and the impacts
of management in similar environments.
• To protect and maintain representative or key elements of biological diversity at the
genetic, species, population, community, or ecosystem levels.
• To serve as areas for the study of ecosystems and ecological processes including
succession.
• To provide onsite and extension educational activities.
• To serve as baseline areas for measuring ecological change.
Uses that retain the research values for which the site is designated are appropriate.
Established
Research Natural Areas include:
• Cahuilla Mountain
• Fisherman's Camp
• Hall Canyon
• Horse Meadow
• Millard Canyon
Recommended Research Natural Areas include:
• Arrastre Flat
