Research natural areas on national forest system lands in Idaho, Montana, Nevada, Utah, and western Wyoming : a guidebook for scientists, managers, and educators by Angela Evenden( )

4 editions published in 2001 in English and held by 386 WorldCat member libraries worldwide

This guidebook is intended to familiarize land resource managers, scientists, educators, and others with Research Natural Areas (RNAs) managed by the USDA Forest Service in the Northern Rocky Mountains and lntermountain West. This guidebook facilitates broader recognition and use of these valuable natural areas by describing the RNA network, past and current research and monitoring, management, and how to use RNAs
Collaborative management and research in the Great Basin : examining the issues and developing a framework for action( )

4 editions published in 2008 in English and held by 255 WorldCat member libraries worldwide

The Great Basin is one of the most imperiled regions in the United States. Sustaining its ecosystems, resources, and human populations requires strong collaborative partnerships among the region's research and management organizations. This GTR is the product of a workshop on "Collaborative Watershed Research and Management in the Great Basin" held in Reno, Nevada, November 28 through 30, 2006. It provides an overview and individual issues papers describing critical research and management issues facing the Great Basin. It also includes summaries of workshop sessions on (1) developing collaborative management and research programs and (2) devising mechanisms for organization and communication. Co-sponsors of the workshop included the University of Nevada, Reno, Desert Research Institute; Great Basin Cooperative Ecosystems Studies Unit; Utah State University; Agricultural Research Service; Bureau of Land Management; State of Nevada, Department of Wildlife and Game; USDA Forest Service, Region 4; USDA Forest Service, Rocky Mountain Research Station; and U.S. Geological Survey

Effects of environmental conditions on germination and early seedling development in Agropyron spicatum by Angela Evenden( Book )

1 edition published in 1983 in English and held by 1 WorldCat member library worldwide

This research evaluated the germination and early seedling development response of two sources of bluebunch wheatgrass (Agropyron spicatum) to a wide range of environmental conditions. Seeds collected near John Day, Oregon and Secar seed obtained from the Soil Conservation Service were used in the investigations. Evaluation of the germination response to conditions of controlled temperature and moisture stress revealed similarities and differences between the two sources. Seed of both John Day and Secar germinated over the widest range of water potentials at 20 C. In all temperature regimes, rate of germination and total percent germination declined as moisture stress increased. As temperature moved away from the optimum 20 C, seeds were less able to germinate at increasing levels of moisture stress. Secar seed germinated better than John Day seed at higher levels of moisture stress when temperatures were favorable. At high temperatures (30 C), germination of Secar was suppressed at all levels of moisture stress, where John Day germinated well at 30 C and lower levels of moisture stress. The effects of several soil moisture regimes on seedling development of the two sources of bluebunch wheatgrass were studied in a greenhouse trial. Soil moisture conditions were the same for all treatments through the emergence period, and John Day seedlings emerged faster than Secar seedlings. Since moisture was adequate at the onset of the study, all seedlings had an opportunity for initial growth and to develop good seminal root systems. Since John Day seedlings emerged first, they had a longer period for growth which resulted in larger herbage and root biomass production than in Secar. As soil moisture decreased, however, the rate and amount of seedling growth for both sources was suppressed. When seedlings were in the three-leaf stage and exposed to surface soil moisture above field capacity, adventitious roots were initiated. Secar seedlings developed adventitious roots sooner than John Day seedlings and produced significantly more and longer adventitious roots than John Day seedlings. Subsurface soil moisture above field capacity provided a favorable environment for rapid extension of adventitious roots once initiation had occurred. Secar seedling development was also related to soil moisture and air temperature in a field study, and findings were similar to the results of the greenhouse study. Seedlings subjected to several weeks of dry soil conditions did not develop well. Most seedlings did not develop three leaves until the tenth week after planting when rainfall increased soil mositure to field capacity. This moisture also stimulated initiation of adventitious roots. However, at the end of the 10 week study adventitious root system length averaged only 5.6 cm, and at this depth these roots would be very susceptible to drying conditions

Species-specific phenological responses to winter temperature and precipitation in a water-limited ecosystem( )

Abstract : Phenology is the study of seasonal biological events such as flowering, leaf-out, insect emergence, and animal migration. Long-term observational studies at numerous temperate zone sites have found that the timing of phenological events responds to temporal variation in climate. To assess the phenological effects of climatic variation on California's flora, The California Phenology Project (CPP) was established in 2010 to develop and to test monitoring protocols and to create tools to support long-term phenological monitoring and education in several California national parks. The CPP uses standardized protocols developed in collaboration with the USA National Phenology Network (USA-NPN) to track the phenological status of 30 plant species across key environmental gradients (e.g., latitude, elevation, and precipitation). To date, over 860K phenological records collected by trained citizen scientists, natural resource managers, and park interns participating in the CPP have been contributed to the National Phenology Database. Observations recorded up to twice per week during the first 40 months of monitoring by the CPP were of sufficiently high resolution to detect associations between local climatic conditions and the onset of targeted phenophases. Here, we present analyses of four of the most intensively-monitored species: Baccharis pilularis (Asteraceae), Quercus lobata (Fagaceae), Sambucus nigra (Caprifoliaceae), and Eriogonum fasciculatum (Polygonaceae). We examined the effects of monthly climate parameters during a four month window (December to March), including mean minimum temperatures (Tmin), total monthly precipitation, and their interactions, on the onset dates of four phenophases per species. Stepwise regressions explained a high proportion (30-99%) of the variation in the onset date of each phenophase. Species and phenophases differed, however, with respect to the strength and the direction of the relationship between each month's conditions (Tmin and/or precipitation) and the timing of vegetative and reproductive phenophases. Given the high climatic variation represented among the monitored sites and among years (2011-2013), it was possible to detect significant associations between local, recent winter conditions and the onset dates of subsequent phenophases, although interactions between monthly conditions were also common. These patterns permit preliminary predictions regarding how these species will respond to future winter warming and intensifying drought
