Topography, disturbance and climate: subalpine forest change 1972-2013, Rocky Mountain National Park, USA
… forest plots originally surveyed in 1972-73 in Rocky Mountain National Park (RMNP) to investigate changes in species composition and structure and assess species migration during the past 40 years. I specifically considered forest change and migration in the context of topography, disturbance …

Impacts of elk management and riparian condition on songbirds in Rocky Mountain National Park
… effects on ecosystems. As in other western parks, riparian willow (Salix spp.) communities in Rocky Mountain National Park (RMNP) are declining as a result of a trophic cascade involving the local extinction of wolves (Canis lupus) and an exponential increase in elk (Cervus elaphus). In …

Assessing vegetation reestablishment on disturbed high mountain lakeshores following historic dam removal in Rocky Mountain National Park, Colorado, USA
… In 1982, then-79-year-old Lawn Lake Dam in Rocky Mountain National Park failed, resulting in three deaths, and extensive monetary damages and destruction of natural resources within the Park. This was followed by a policy decision to remove three dams in the Park between 1988 and 1990, …

Cheatgrass (Bromus tectorum L.) management and native plant community recovery on sites selectively treated with Imazapic in Rocky Mountain National Park
… subalpine plant communities and ecosystems of Rocky Mountain National Park (RMNP). Cheatgrass aggressively invades disturbed sites and competes with native plant species by rapidly establishing a root system capable of depleting soil moisture and available nitrogen, making cheatgrass control a …

Monitoring amphibian populations and the status of wood frogs and boreal chorus frogs in the Kawuneeche Valley of Rocky Mountain National Park
… probabilities, from 2004 to 2006 in a valley in Rocky Mountain National Park. I also evaluated hypothesized relationships between occupancy and attributes measured at multiple spatial scales. Erin Muths and Barry Noon were co-authors on this chapter. Breeding wood frogs occupied approximately 12% …

Riparian willow dynamics and their interaction with environmental and biological factors in the elk winter range of Rocky Mountain National Park (Colorado) - a multi-scale analysis
… in two valleys of the elk winter range of Rocky Mountain National Park (Colorado). Studies at the individual, population, and landscape scale were conducted, and results from these studies were incorporated into a spatial, process based model (SAVANNA). Morphological and physiological …

Using Repeat Photography to Examine Change in a U.S. National Park Gateway Community: A Case Study of Estes Park, Colorado
<p>Since the creation of the National Park Service in the United States, tourists from around the world visiting America's national parks are served by gateway communities. Gateway communities are the towns and cities that border public lands and protected spaces. The impact of our visits on these …

Soil-plant-herbivore interactions and nutrient dynamics in semi-arid grazing systems in northeastern Brazil and western USA
… to areas where all trees were removed. In Rocky Mountain National Park (RMNP), Colorado, we found that herbivores had a significant influence on nutrient pools, fluxes between pools, and also on ecosystem structure by possibly reducing the ability of Salix shrubs to take up N from the …

Groundwater-surface water exchange within montane and alpine regions of the Front Range and Rocky Mountains, Colorado
… will diminish a crucial storage of water in mountainous regions and thus decrease water availability to Front Range communities and to agricultural regions in the Midwest. To characterize how water resources and quality will alter with time and with this hydrologic change, I have examined …

A damming history: an analysis on the legacy effects of beaver dams on the composition and structure of a montane riparian ecosystem
… study was conducted in the Kawuneeche Valley of Rocky Mountain National Park, Colorado. Field methods focused on vegetative surveys around historic, off-channel beaver dams, the Colorado River, and its major tributaries. Observed beaver sign was classified by age (historic, recent/current, …

Riparian willow decline in Colorado: interactions of ungulate browsing, native birds and fungi
Willows (Salix spp.) are critical components of Rocky Mountain riparian ecosystems. They provide food for ungulates and beavers; habitat for resident and migratory bird populations, and amphibians; and are integral components of the structure and function of montane riparian ecosystems. In Rocky …
