The distribution and abundance of populations limited at multiple spatial scales

Publications Posted on: December 16, 2019
We use mathematical programming to explore long-term equilibrium population distribution and abundance effects arising from a single-patch reaction-diffusion model when ecological factors limit carrying capacity at two different spatial scales. Both homogeneous and heterogeneous habitat patches are investigated under passive diffusion conditions.

Visitor perception of wilderness recreation carrying capacity

Publications Posted on: May 31, 2018
Presents results of a study of wilderness users in the Bob Marshall, Bridger, High Uintas, and the Boundary Waters Canoe Area (BWCA) to determine their perception of, and reaction to, problems such as crowding, littering, and conflicts between user groups, and to management actions to alleviate such problems.

Bob Marshall Wilderness Complex (BMWC) 1982 visitor characteristics, attitudes, and use patterns

Datasets Posted on: March 15, 2018
The data included in this publication include visitor characteristics, attitudes towards the wilderness experience, and use patterns for wilderness visitors to the Bob Marshall Wilderness Complex (BMWC) in 1982. Visitors were asked to provide contact information for a mail-back survey.

MODIS-based annual production estimates from 2000-2015 for rangelands in USFS grazing allotments in Region 5

Datasets Posted on: March 15, 2018
This data publication contains an ESRI grid dataset describing annual productivity and drought in the non-forest domain of Region 5 (California) of the United States Forest Service (USFS). Production data were generated from the Rangeland Vegetation Simulator (RVS).

Visitor use density and wilderness experience: proceedings; 2000 June 13; Missoula, MT

Publications Posted on: May 12, 2016
The workshop was convened to assess progress and offer further ideas regarding scientific contributions to (1) understanding relationships between visitor use density and wilderness experiences and (2) applying such knowledge to decisions about use limitation in wilderness and parks. The first paper provides an overview of the topic and the papers presented at the workshop.

Use patterns and visitor characteristics, attitudes, and preferences in nine wilderness and other roadless areas

Publications Posted on: March 23, 2015
Presents a summary and analysis of data from a survey of visitors to eight wildernesses and related areas in the Montana and Idaho Rockies and to one wilderness in the California Sierra Nevadas.

Carrying capacity for species richness as context for conservation: a case study of North American birds

Publications Posted on: July 03, 2013
We evaluated the leading hypotheses on biophysical factors affecting species richness for Breeding Bird Survey routes from areas with little influence of human activities.We then derived a best model based on information theory, and used this model to extrapolate SK across North America based on the biophysical predictor variables.

Capacity reconsidered: Finding consensus and clarifying differences

Publications Posted on: October 05, 2011
In a world where populations and resource demands continue to grow, there is a long history of concern about the "capacity" of the environment to support human uses, including timber, rangelands, fish and wildlife, and recreation.

Wilderness solitude: Beyond the social-spatial perspective

Publications Posted on: September 19, 2011
The current scholarly and management approach to wilderness solitude has relied on substitute measures such as crowding and privacy to measure solitude. Lackluster findings have been only partially explained by additional social-spatial factors such as encounter norms, displacement, product shift, and rationalization.

Limiting recreational use in wilderness: Research issues and management challenges in appraising their effectiveness

Publications Posted on: September 19, 2011
Limits on the overall number of recreationists permitted to enter or visit wilderness, national park backcountry or whitewater rivers have been formally established for about 30 years. Such limits have usually been established to protect biophysical or social conditions from unacceptable impacts in the face of rapidly rising amounts of visitation.
