“…The number of plots per vegetation type varied slightly depending on the total acreage of these types on the NTS. Results of the initial survey are described in Hansen et al, 2009. In 2009, the black sagebrush and big sagebrush plots were sampled to determine cover and density during a year of drought. The pinyon/black sagebrush and pinyon/big sagebrush sites were not sampled in 2009, due to other monitoring priorities, but it is anticipated that they will be surveyed in 2010.…”

“…The habitat for C. ripleyi var. saniculoides was described as "white ash deposits" (Barneby, 1941 (Photographs by D. C. Anderson, 2009) Based on the review of previous field notes and the results of field surveys conducted this year, there is no evidence that both varieties are commonly or even occasionally found at the same location. There appears to be a clear definition of purple-colored flowers at lower elevations and cream-colored flowers at upper elevations, an observation made by Barneby some 70 years ago.…”

“…Small mammal sampling was conducted as in previous years (see Hansen et al, 2009, for details of trapping; Figure 6-6). Trapping design included two trap lines, one in each comparative habitat, such as a wash and an upland habitat.…”

NSTec), during calendar year 2009. Program activities included (a) biological surveys at proposed construction sites, (b) desert tortoise compliance, (c) ecosystem mapping and data management, (d) sensitive plant species monitoring, (e) sensitive and protected/regulated animal monitoring, (f) habitat monitoring, (g) habitat restoration monitoring, and (h) monitoring of the Nonproliferation Test and Evaluation Complex. During 2009, all applicable laws, regulations, and permit requirements were met, enabling EMAC to achieve its intended goals and objectives.Sensitive and protected/regulated species of the NTS include 43 plants, 1 mollusk, 2 reptiles, 238 birds, and 27 mammals. These species are protected, regulated, or considered sensitive according to state or federal regulations and natural resource agencies and organizations. The threatened desert tortoise (Gopherus agassizii) is the only species on the NTS protected under the Endangered Species Act. Biological surveys for the presence of sensitive and protected/regulated species and important biological resources on which they depend were conducted for 31 projects. A total of 437.58 hectares (ha) (1081.29 acres [ac]) was surveyed for these projects. Sensitive and protected/regulated species and important biological resources found during these surveys included active tortoise burrows, active kit fox (Vulpes velox macrotis) burrows, a predator burrow, mature Joshua (Yucca brevifolia) trees, Mojave yuccas (Yucca schidigera), possibly Tonopah milkvetch (Astragalus pseudiodanthus), Beatley milkvetch (Astragalus beatleyae), Cane Spring suncup (Camissonia megalantha), and cacti. NSTec provided a written summary report of all survey findings and mitigation recommendations, where applicable. All flagged tortoise burrows were avoided during project activities.Of the 31 projects on the NTS, 24 projects occurred within the range of the threatened desert tortoise. NNSA/NSO must comply with the terms and conditions of the Biological Opinion rendered by the U.S. Fish and Wildlife Service (FWS) when conducting work in desert tortoise habitat. No tortoises were found in project areas, nor were any accidentally injured, killed, captured, or displaced during project activities. One desert tortoise was killed by a vehicle along the 5-05 Road in Area 5. Five desert tortoises were removed from roads by NTS personnel to avoid injury or death. In 2009, approximately 3.27 ha (8.08 ac) of tortoise habitat were disturbed. Two projects paid mitigation fees for areas that were disturbed in 2009. On July 2, 2008, NNSA/NSO sent a Biological Assessment to the FWS and entered into formal consultation for a new programmatic opinion for the NTS. That consultation ended on February 12, 2009, when FWS sent the final Biological Opinion to NNSA/NSO. This Opinion covers anticipated activities at the NTS for the next 10 years.There has been an average of 11.8 wildland fires per year on the NTS since 1978 with an average of about 81.6 ha (201.6 ac) burned per fire. In 2009, there were 17 wildland fire...
