Continue genetic studies with the goal of clarifying relationships between S. idahoense and S. sarmentosum, and between occurrences (de facto populations) of S. sarmentosum. Information gained through such studies will likely inform management of the species. See Section V. Inventory, Monitoring, and Research for specific recommendations. Camping/recreation Eliminate impacts from camping, recreation, and motor-vehicle access within occupied and suitable habitat. Potential actions: Post signs. Remove and rehabilitate areas with fire rings or other signs of impactful recreation. Install boulders, fencing, gates, or other barriers to prevent motor-vehicle access to habitat. Revise Forest Plans when S. sarmentosum conservation conflicts with management direction. Conduct environmental education designed to increase public awareness of special habitats. This may involve periodic patrols of occupied habitat to detect impactful behavior, and disseminate information to recreationists. Habitat-Disturbing Management Activities Conserve all known occurrences of the species on public lands included in this Conservation Strategy. Potential actions: Conduct pre-project surveys in habitat (preferably during the S. sarmentosum blooming period) to increase the probability that occurrences are detected. Evaluate potential impacts of habitat-disturbing activities on S. sarmentosum occurrences and habitat. Implement management activities (including prescribed fire) within S. sarmentosum occupied habitat only when the benefit to the occurrence is considered to be greater than the impact to the occurrence (i.e., loss of individuals or habitat). Short-term impacts from management activities to occurrences and habitat may be permitted if long-term benefits are expected. Under no circumstances should management activities threaten the persistence and/or viability of an occurrence. Create no brushing/no parking zones around roadside occurrences. Other opportunities or actions and Habitat Conservation Maintain or improve occupied and suitable habitat. Potential actions: Implement habitat restoration projects that maintain the open conditions of occupied and suitable habitat by removing small trees and shrubs. When appropriate to meet site specific occurrence recommendations, consider removing larger trees in meadow habitat,

INVENTORY, MONITORING, and RESEARCH Inventory Sisyrinchium sarmentosum is cryptic, and may be easily overlooked or misidentified when not in the blooming/fruiting stage, a circumstance that may have led to under-detection during past surveys. In addition, the wide range of variability within S. idahoense, and the fact that the two species are sometimes found together, may have led to under-detection of the rare species in mixed occurrences. For these reasons, it is recommended that known occurrences of S. idahoense be re-visited and searched for S. sarmentosum. Below are listed inventory needs, by National Forest.
