چکیده
Abstract Invasive Hieracium plant species are invading the Greater Yellowstone Ecosystem. The potential distribution of orange hawkweed ( aurantiacum) and meadow caespitosum) were estimated using habitat susceptibility models to assist land managers’ management these invasive plants. objectives this study to: (1) develop describing ecosystems invasion, (2) identify indicator hawkweed, (3) determine types where hawkweeds might occur, (4) create maps for planning ground surveys. Models developed a Mahalanobis distance similarity technique from remotely sensed biotic abiotic variables, as well known location data hawkweed. Ground validation was conducted assess model weaknesses subsequent modification. Indicator identified surrogates likelihood presence during survey. Transect collected areas susceptible invasion also used occur. best included eight variables: north–south aspect, east–west slope, NDVI, NDWI, blue spectral band, green precipitation. High (65 + % suitable habitat) consisted 66,000 ha 35,000 5.0% 2.7% area, respectively. Meadow had seven three species, Predicted encompassed nine types, ranging xeric sagebrush steppe wet forests they overlapped except at type. Habitat save costs allow survey prioritization those most invasion.

Elk migration patterns and human activity influence wolf habitat use in the Greater Yellowstone Ecosystem.
Identifying the ecological dynamics underlying human-wildlife conflicts is important for the management and conservation of wildlife populations. In landscapes still occupied by large carnivores, many ungulate prey species migrate seasonally, yet little empirical research has explored the relationship between carnivore distribution and ungulate migration strategy. In this study, we evaluate the...
متن کاملThe Greater Yellowstone Ecosystem: challenges for regional ecosystem management.
An adaptive management approach is necessary but not sufficient to address the long-term challenges of the Greater Yellowstone Ecosystem (GYE). Adaptive management, in turn, has its own particular challenges, of which we focus on two: science input, and stakeholder engagement. In order to frame our discussion and subsequent recommendations, we place the current management difficulties into thei...

The Greater Yellowstone Ecosystem, a 7.6-million-hectare region in the Central Rocky Mountains of the United States, is used to illustrate both the challenges and means to improve problem solving in the natural resources arena. The challenges in this world-famous region are contextual (rapid change, growth, pluralism, complexity, state/federal conflicts, and lack of a common perspective), insti...
