. Assessment of aquatic macroinvertebrates in USFS / BLM Lands of the Crooked and Sage Creek Watersheds [electronic resource]. Bycatches; Bycatches (Fisheries); Evaluation. Pinev Creek (BLM Section YL Prl84) Ecoregion: Bighorn-Pryor Foothills/Wyoming Basin (Typical) Aquatic Ecological System Type: Small Transitional Foothills Stream (AES COOly) Key Environmental Factors: Riparian Grazing & Cattle Use—slight impacts in the BLM section, some pocking and hummocking, none in the USFS spring outflow area. High discharge spring about 500m upstream. Rare or Unique Species: Reported Yellowstone cutthroat trout in reach (USFS pers. comm.). No SOC rare invertebrate species, but a good quality cold-water assemblage dominating the macroinverts. Rare Features: No rare features documented, except a high discharge spring about 500m upstream pumping out pure snowmelt @ 5 degrees C. Riparian Ranking: BLM= 19 (79%) Functional At Risk Riparian Condition (FAR) Geomorphology: Rosgen B3 Substrate looks very similar to Crooked Creek canyon sites including moss covered cobbles. Introduced/Exotic Aquatic Species: None documented Overall Ecological Site Condition: Good (2007 & 2008) Macroinvertebrate Community: A good quality & fairly diverse community of 29 taxa, including 9 cold-water obligate taxa, despite some obvious sediment and grazing issues within the reach. Macroinvertebrate Community Quality: MT MMI= Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Stagliano, David M; Montana Natural Heritage Program; United States.
