Stream Survey and Functional Condition Assessment

  • Client: Elko District, BLM, Elko County, NV
  • Date: Aug 2011 to Dec 2011
  • Info: Blue Mountain Environmental was contracted by the Bureau of Land Management, Elko District, to monitor riparian conditions and fisheries habitat within various grazing allotments.

Thirty-seven miles of waterways in nine different drainages were assessed to monitor the effect of livestock grazing on riparian condition and fisheries habitat. The Proper Functioning Condition assessment (BLM TR1537) was utilized as a qualitative process to evaluate hydrology, vegetation and erosion and deposition processes within each waterway while the Aquatic Habitat Inventory and Monitoring Level III Survey Procedures (Elko Revised Handbook 6720-1) provided detailed information about fisheries habitat and grazing impacts. Waterways occurred within five different grazing allotments, which had undergone different ecological processes such as fire and historical overgrazing. Survey work required accessing extremely remote areas within and adjacent to the Jarbone Wilderness and assessing conditions on perennial, intermittent and ephemeral drainages. Repeat photographs, survey notes and GPS data were collected to contribute to future monitoring efforts.
