Vantage to Pomona Heights Chapter 4 <br />230 kV Transmission Line Project FEIS Environmental Consequences <br /> PAGE 4-55 <br />RESOURCE CATEGORY SENSITIVITY POTENTIAL IMPACT FROM THE PROPOSED PROJECT <br />Sagebrush/Perennial Grassland (Breeding, Late <br />Brood-rearing/Summer, and Winter Habitat) High Reduction in quality habitat that is slow to recover from <br />disturbance. <br />Greater Sage-Grouse lek – within > 4 miles from <br />the proposed transmission line and within suitable <br />habitat <br />Moderate <br />Disturbance and displacement of breeding grouse; <br />increased predation; behavioral avoidance; reduction in <br />breeding habitat. <br />Greater Sage-Grouse Connectivity Habitat <br />Management Unit High Reduction in habitat (abundance and quality) that serves <br />as a movement corridor between seasonally used areas. <br />Non-forested Riparian, Intermittent Stream <br />(Breeding and Late Brood-rearing/Summer <br />Habitat) <br />Moderate <br />Reduction in habitat that could serve as suitable <br />seasonal habitat, especially during breeding and <br />summer. <br />Bitterbrush/perennial grassland (Potential <br />Breeding and Late Brood-rearing/Summer <br />Habitat, depending on surrounding vegetation) <br />Moderate <br />Reduction in habitat that could be used as breeding and <br />late brood-rearing/summer habitat <br />Sagebrush/Annual Grassland (Winter Habitat) Moderate Reduction in disturbed habitat that could provide <br />potential suitable seasonal habitat. <br />Greater Sage-Grouse Expansion Habitat <br />Management Unit Low Reduce habitat (abundance and quality) that could serve <br />as expansion areas for Sage-Grouse. <br />Perennial Grassland (Potential Summer Habitat, <br />depending on surrounding vegetation) Low Reduction in habitat that could be used as summer <br />habitat. <br />Annual grassland, noxious weeds, <br />rabbitbrush/annual grassland, <br />developed/disturbed (Unsuitable Habitat) <br />Low <br />Reduction in unsuitable vegetation or disturbance in <br />developed/disturbed areas. <br /> <br /> <br />Table 4.3-3 Summary of Impacts to Wildlife Resources <br />IMPACT PROJECT ATTRIBUTE <br />POTENTIAL IMPACT <br />AND WILDLIFE <br />RESOURCE EFFECT <br />IMPACT CATEGORY <br />AND LONGEVITY <br />Direct injury and/or <br />mortality to vegetation <br />(habitat) <br />Vehicle and human <br />trampling during construction <br />and maintenance. <br />Destruction, mortality, and <br />injury to vegetation, reduction <br />in habitat quantity and quality. <br />Biological disturbance and <br />Biological change. <br /> <br />Short-term in areas adjacent to <br />the Project right-of-way (ROW). <br /> <br />Long-term in areas associated <br />with clearing and grading for <br />access roads and transmission <br />structures. <br />Direct injury and/or <br />mortality to wildlife <br />Vehicle and human <br />trampling during construction <br />and maintenance. <br />Destruction, mortality, and <br />injury to wildlife species. <br /> <br />Species with limited mobility <br />or that occupy burrows or <br />nests are most susceptible. <br /> <br />Destruction of nests. <br />Biological change. <br /> <br />Short-term within the footprint <br />from construction and structures <br />and in areas adjacent to the <br />Project ROW. <br /> <br />Long-term for access roads.
