“…In the long term, net losses of N by combustion and streamwater export will be offset by N-fixation and atmospheric deposition (Smithwick et al, 2005). In contrast to wildfires, low-severity spring prescribed burns did not provide the stream ecosystem with potentially important nutrient pulses (Arkle and Pilliod, 2010). Whereas chronic N inputs from atmospheric or other pollution will lead to detrimental effects on water quality and aquatic organisms, short-term inputs of post-fire N, as often observed after wildfires, may be critical for the productivity of often N-limited aquatic ecosystems while not impairing water quality.…”

“…To determine if certain combinations of landcover types were important predictors of sage-grouse occupancy, we performed a non-metric multi-dimensional scaling (NMS) ordination of landcover data for each plot using PC-ORD 6.09 software (McCune and Mefford 2011). This analysis was conducted as in Arkle and Pilliod (2010), but without transformations. We used the three axis scores v www.esajournals.org generated for each plot (in addition to values of individual landcover variables) as potential predictors in subsequent analyses.…”

. 2014. Quantifying restoration effectiveness using multi-scale habitat models: implications for sage-grouse in the Great Basin. Ecosphere 5(3):31. http://dx.doi.org/10.1890/ES13-00278.1Abstract. A recurrent challenge in the conservation of wide-ranging, imperiled species is understanding which habitats to protect and whether we are capable of restoring degraded landscapes. For Greater Sage-grouse (Centrocercus urophasianus), a species of conservation concern in the western United States, we approached this problem by developing multi-scale empirical models of occupancy in 211 randomly located plots within a 40 million ha portion of the species' range. We then used these models to predict sage-grouse habitat quality at 826 plots associated with 101 post-wildfire seeding projects implemented from 1990 to 2003. We also compared conditions at restoration sites to published habitat guidelines. Sage-grouse occupancy was positively related to plot-and landscape-level dwarf sagebrush (Artemisia arbuscula, A. nova, A. tripartita) and big sagebrush steppe prevalence, and negatively associated with non-native plants and human development. The predicted probability of sage-grouse occupancy at treated plots was low on average (0.09) and not substantially different from burned areas that had not been treated. Restoration sites with quality habitat tended to occur at higher elevation locations with low annual temperatures, high spring precipitation, and high plant diversity. Of 313 plots seeded after fire, none met all sagebrush guidelines for breeding habitats, but approximately 50% met understory guidelines, particularly for perennial grasses. This pattern was similar for summer habitat. Less than 2% of treated plots met winter habitat guidelines. Restoration actions did not increase the probability of burned areas meeting most guideline criteria. The probability of meeting guidelines was influenced by a latitudinal gradient, climate, and topography. Our results suggest that sage-grouse are relatively unlikely to use many burned areas within 20 years of fire, regardless of treatment. Understory habitat conditions are more likely to be adequate than overstory conditions, but in most climates, establishing forbs and reducing cheatgrass dominance is unlikely. Reestablishing sagebrush cover will require more than 20 years using past restoration methods. Given current fire frequencies and restoration capabilities, protection of landscapes containing a mix of dwarf sagebrush and big sagebrush steppe, minimal human development, and low non-native plant cover may provide the best opportunity for conservation of sage-grouse habitats.

“…Prescribed fire treatments were conducted under dry, low-wind conditions in early May 2004 (Parks site) and early May 2006 (Fitsum and Williams sites) using incendiary objects dropped from a helicopter and hand-held drip torches near treatment perimeters. Methods, guidelines, and treatment objectives were the same for all three prescribed fires and are described in Arkle and Pilliod (2010). The Parks treatment burned within a 1052 ha area (29% Unburned-Low, 57% Low, 13% Moderate, and 0.7% High severity).…”
