Total 14 Parcels 16,598.88 2 Soil Types and Plant Communities 2.1 Soil Types in the Analysis Area Aridisols Aridisol are soils that are too dry for the growth of mesophytic plants. The lack of moisture greatly restricts the intensity of weathering processes and limits most soil development processes affecting the uppermost layers of the soils. These soils often accumulate gypsum, salt, calcium carbonate, and other materials that are easily leached from soils in more humid environments. They have properties typical of soils in arid regions and are low in organic matter. Aridisols are mainly found in valley bottoms, but may occur at higher elevations. They do not have water continuously available during the growing season and typically have a water stress period of about 3 months. Aridisols tend have a finer texture than the other two orders. Entisols Entisols are found on recent landscapes, such as alluvium and disturbed sites. Soil texture tends to be more gravely and well drained. Entisols are mineral soils that are very young and have not yet developed appreciable accumulations of soluble salts and lime. Soil horizon development is typically minimal. They occur in both the valley bottoms and higher elevations. In the mountains these tend to make up the steeper, more erodible soils, whereas at lower elevation they tend to be found in areas of deposition such as alluvial fans and floodplains. Though these sites are typically xeric, they are not as dry as the Aridisols. Inceptisols Inceptisols, like Entisols, are new, poorly developed soils characteristic of recent landscapes. Well-defined soil horizons are mostly absent, though, unlike Entisols, Inceptisols often have the beginnings of B Horizon development apparent. This B Horizon is often cambic in nature, but may consist of duripans, fragipans, or calcic horizons. Microbiotic Crusts Microbiotic crusts are a complex mosaic of cyanobacteria, green algae, lichens, mosses, microfungi, and other bacteria found throughout the Great Basin and Project Area. Cyanobacterial and microfungi filaments weave through the top few millimeters of soil, gluing loose particles together and forming a matrix that stabilizes and protects soil surfaces from erosive forces. Microbiotic crusts retain soil moisture, discourage invasion by annual species, reduce win and water erosion, fix atmospheric nitrogen and contribute to soil organic matter. These crusts can be impacted

  • Germination and Seedling Establishment of Spiny Hopsage (Grayia Spinosa [Hook.] Moq.)
    AN ABSTRACT OF THE THESIS OF Nancy L. Shaw for the degree of Doctor of Philosophy in Crop and Soil Sciences presented on March 19, 1992 Title: Germination and Seedling Establishment of Spiny Hopsage (Grayia Spinosa [Hook.] Moq.) Abstract approved:_Redactedfor Privacy von r. ULdUe Reestablishment of spiny hopsage(Grayia spinosa [Hook.] Moq.) where depleted or lost on shrub steppe sites can improve forage, plant cover, and soil stabilization. The objectives of this study were to: 1) determine direct-seeding requirements; 2) develop optimum germination pretreatments; and 3) examine dormancy mechanisms in spiny hopsage fruits and seeds. The effects of seed source, planting date,and site preparation method onseed germination and seedling establishment (SE) were examined at Birds of Prey and Reynolds Creek in southwestern Idaho. Three seed sources were planted on rough or compact seedbeds on 4 dates in 1986-87 and 3 dates in 1987-88. Exposure to cool-moist environments improved spring SE from early fall (EF) and late fall (LF) plantings. Few seedlings emerged from early (ESp) or late spring (LSp) plantings. SE was low at: 1 site in 1986-87 and atboth sites in 1987-88, probably due to lack of precipitation. For the successful 1986-87 planting, seedling density was greater on rough compared to compact seedbeds in April andMay, possiblydue to improved microclimate conditions. Growth rate varied among seed sources, but seedlings developed a deep taproot (mean length 266 mm) with few lateral roots the first season. Seeds were planted on 3 dates in 1986-87 and 1987-88, andnylon bags containing seeds were planted on 4 dates each year to study microenvironment effects on germination (G), germination rate (GR), and SE.

Surface disturbances during exploration activities will consist primarily of the creation of new exploration roads, drill pits, and sumps. At any given time within the 17,316-acre EPO Area, a maximum of 100 acres of unreleased Proposed Action-related disturbance will exist. Release of reclaimed lands 3 Geology & Minerals --- Localized Short-term Negligible Not Significant could occur as early as the third growing season as stated in the BLM and NDEP bond release policy. Overall, it is anticipated that the program will be conducted over 10 years with total unreleased disturbance not exceeding 100 acres at any point in time and with a total project reclaimed disturbance not exceeding 200 acres (based on concurrent reclamation being released for future phases of exploration activities). Changes in runoff distribution would be negligible and the overall effect on surface water resource would be negligible. The Proposed Action is expected to have a negligible effect on snowmelt recharge to shallow groundwater within EPO Surface Water Localized Short-term Negligible Not Significant Area. BMPs to control stormwater, sediment erosion, and protect surface water resources from pollution related to surface disturbance activities would be implemented to reduce the potential for temporary effects to water quality.

Biological parameters 2.1 Distribution S. spinosior spp. blainei is reported as occurring in Nye and Lincoln Counties, Nevada, and Iron County, Utah, United States of America (Anderson, 2001; Kartesz, 1999). The Utah Natural Heritage Program does not consider the taxon to be present in Utah (Franklin, pers. comm., 2002). Taxonomic uncertainty regarding this taxon confounds the issues related to its distribution. According to Dr. Morefield, Nevada Natural Heritage Program, “the descriptions and circumscriptions of S. blainei, S. nyensis, and S. schlesseri are highly inconsistent within and among the recent treatments” (NatureServe, 2002). The treatment given in the CITES Cactaceae Checklist has been followed for the purposes of this proposal. In addition the taxon will be considered as occurring in Utah until the disagreement over distribution has been definitely resolved.
