The dataset supports a larger study that examined the impacts of three tackifiers (guar, psyllium, and polyacrylamide) on growth of two dryland mosses (Bryum argenteum and Syntrichia ruralis). Moss fragments were grown in petri dishes and subjected to individual tackifiers in one of three possible concentrations (0.5x, 1x, or 2x) of the respective manufacturer's recommended application rate. Distilled water was used as a control treatment, giving a total of ten treatments (nine tackifier-concentration combinations and a water control). Bryum fragments were watered four times daily for six weeks and Syntrichia fragments were watered twice daily for five weeks, after which the experiments were concluded. Shoot length, shoot number, gemma presence, protonema presence, bound sand mass, and moss organic matter mass were all measured at the end of the experiments. This dataset reports all measurements and calculations related to Bryum argenteum and Syntrichia ruralis and additional information describing mass determinations.

This dataset reports mass adjustment ratios (average non-moss organic matter mass in milligrams per 1 milligram of bound sand mass) that were used to subtract non-moss organic matter mass from total organic matter mass measurements, ultimately calculating moss organic matter mass per fragment at the end of the experiment. Total organic matter mass was determined by placing fragments and attached substrate in a furnace and burning off organic matter. The post-furnace weight was subtracted from the pre-furnace weight to calculate total organic matter mass, with the remaining weight representing the bound sand mass. A separate experiment was performed without moss fragments, but with tackifier and sand, and subjected to the same furnace process to determine the proportion of total organic matter mass made up of sand organic matter and tackifier. Bryum and Syntrichia were grown on different sand types, which were composed of different amounts of organic matter and resulted in different adjustment ratios for Bryum and Syntrichia experiments.

This dataset contains data supporting the paper: DeCrappeo, N.M., DeLorenze, E.J., Giguere, A.T., Pyke, D.A., and Bottomley, P.J. Fungal and bacterial contributions to nitrogen cycling in cheatgrass-invaded and uninvaded native sagebrush soils of the western USA (accepted at the journal Plant and Soil). The purpose of the study was to evaluate the relative contributions of soil bacteria and fungi to inorganic nitrogen (N) cycling in sagebrush and cheatgrass-invaded soils using a 15N isotope dilution experiment. Soils were collected from sagebrush and cheatgrass rhizospheres at six paired sites in southwest Idaho and southeast Oregon. In order to partition the contribution of each microbial group to N cycling, soils were treated with isotopically labeled N sources and protein synthesis inhibitors. Bronopol and cycloheximide block protein synthesis in bacteria and fungi, respectively; nitrogen can still be taken up by the organisms, but the organisms are unable to assimilate the nutrient into biomass. Laboratory incubations were carried out to study the partitioning of N to microbial biomass and dissolved inorganic nitrogen pools, which were then used to calculate the following nitrogen transformation rates: gross mineralization, net mineralization, ammonium consumption, and net nitrification.

A 30 meter integer grid derived from USGS GAP data published in 2010 of sagebrush land cover within 120 meters of conifer land cover. It is one of several inputs used in the BLM FIAT analysis completed March 2015. FIAT was developed using a process designed to identify strategies that ameliorate threats to Greater Sage-Grouse (GRSG; Centrocercus urophasianus) and their habitats. While the assessment is applicable across the range of sage-grouse, the analysis is limited to Western Association of Fish and Wildlife Management Agencies’(WAFWA) Management Zones III, IV, and V (roughly the Great Basin region) because of the significant issues associated with invasive annual grasses and the high level of wildfires in this region. It incorporates emerging science, regional findings, and local data in identifying management opportunities that counter detrimental ecological trends in wildfire, invasive annual grasses, and conifer expansion. The purpose of the assessment is to identify potential project areas and management strategies in highly valued greater sage-grouse habitats which, if implemented, would reduce the threats to greater sage-grouse.
