Sustainability of vegetation communities grazed by elk in Rocky Mountain National Park
Current management of the worlds' grazing lands in either based on changes in plant species composition or on other management evaluation programs that emphasize changes in net aboveground production. Management is based solely on changes in aboveground production has been criticized as too limited in view, because it ignores root production, nitrogen pools, nutrient processes, and the long-term s

Cascading effects of fire exclusion in Rocky Mountain ecosystems: A literature review
The health of many Rocky Mountain ecosystems is in decline because of the policy of excluding fire in the management of these ecosystems. Fire exclusion has actually made it more difficult to fight fires, and this poses greater risks to the people who fight fires and for those who live in and around Rocky Mountain forests and rangelands. This paper discusses the extent of fire exclusion in the R

How stakeholder roles, power, and negotiation impact natural resource policy: A political economy view
Natural resource management decisions are complicated by multiple property rights, management objectives, and stakeholders with varying degrees of influence over the decision making process. In order to make efficient decisions, managers must incorporate the opinions and values of the involved stakeholders as well as understand the complex institutional constraints and opportunities that influence

SALMOD: A population model for salmonids: user's manual. Version W3
SALMOD is a computer model that simulates the dynamics of freshwater salmonid populations, both anadromous and resident. The conceptual model was developed in a workshop setting (Williamson et al. 1993) using fish experts concerned with Trinity River chinook restoration. The model builds on the foundation laid by similar models (see Cheslak and Jacobson 1990). The model’s premise that that egg and

Managing for biodiversity in young Douglas-fir forests of western Oregon
This project addressed potential contributions of forest thinning to enhancing biodiversity and accelerating development of old-growth characteristics in relatively young Douglas-fir forests typical of those managed according to the Northwest Forest Plan. Studies focused primarily on 32 paired unthinned and thinned stands and 20 associated old-growth stands in the Coast Range and Cascade mountains

Breeding habitat use by sympatric and allopatric populations of Wilson's Warblers and Yellow Warblers
We studied Wilson's Warbler (Wilsonia pusilla) and Yellow Warbler (Dendroica petechia) habitat use in allopatric and sympatric populations in the Rocky Mountains of northern Colorado and southeastern Wyoming in order to better understand the different habitat needs and interactions of these two species. Foraging Wilson's Warblers and Yellow Warblers used very similar habitat, both selecting larger

Influences of herbivory and water on willow in elk winter range
Elimination of large predators and reduced hunter harvest have led to concerns that an increasing elk (Cervus elaphus) population may be adversely affecting vegetation on the low-elevation elk winter range of Rocky Mountain National Park, Colorado, USA. Beaver (Castor canadensis) and their impoundments also have declined dramatically (94%) in the same area over the past 50 years coincident with a

Effects of vegetation management in constructed wetland treatment cells on water quality and mosquito production
The impact of three vegetation management strategies on wetland treatment function and mosquito production was assessed in eight free water surface wetland test cells in southern California during 1998–1999. The effectiveness of the strategies to limit bulrush Schoenoplectus californicus culm density within the cells was also investigated. Removing accumulated emergent biomass and physically limit

Visitor reponse to demonstration fees at National Wildlife Refuges
In response to a request from the United States Fish and Wildlife Service, we examined the likelihood of visitors changing their plans for future visits to National Wildlife Refuges (NWR) because of changes in entrance or use fees. We obtained data for this study from 3,173 respondents from 14 NWRs between 1998 and 2000. Overall, only 8% of all respondents reported potential displacement as a like

Assessing vulnerability to invasion by nonnative plant species at multiple spatial scales
Basic information on where nonnative plant species have successfully invaded is lacking. We assessed the vulnerability of 22 vegetation types (25 sets of four plots in nine study areas) to nonnative plant invasions in the north–central United States. In general, habitats with high native species richness were more heavily invaded than species-poor habitats, low-elevation areas were more invaded th
