surrounding areas should be assessed. An up-to-date inventory will provide information needed to accurately identify conservation and management needs. Since J. acutifilosa populations are found in Fall Creek and Jenny Creek, part of the Klamath River Drainage, additional populations may be present in appropriate habitat of sub-drainages of the Klamath River Drainage. Klamath River sub-drainages that occur on Medford BLM land and in close proximity to J. acutifilosa records include: Skookum Creek, Oregon Gulch, Lincoln Creek, Salt Creek, Dutch Oven Creek, and Mill Creek. Additional sub-drainages that may host this species on the Rogue Siskiyou National Forest include: Grizzly Creek, Hoxie Creek, and Green Creek. Management: Preventive management actions to protect J. acutifilosa habitat is important as this species prefers larger springs and limnocrenes which are dependable water sources often utilized for human development and fish hatcheries. Management for this species could include mitigating damage to springs in this area from irrigation, domestic use, and/or stock water supply. Land managers could also monitor activities associated with roads and railroads, which often lead to water diversion and spring degradation in this area. Grazing effects (e.g., destroying vegetation, damaging soil and stream banks, increased sedimentation and erosion) have also been documented and steps could be taken to reduce these impacts. Threats that degrade water quality and riparian habitats for this species can be mitigated by managing active grazing sites in riparian areas through implementing suitable buffers and installing fences, limiting road construction, and preventing erosion and sedimentation. These management actions would stabilize springs and creeks, protecting and improving existing habitat.
