Land Stewardship in the 21st Century: The Contributions of Watershed Management; 2000 March 13-16; Tucson, AZ

Publications Posted on: May 12, 2016
The purpose of this conference was to increase awareness through exploration and evaluation of global, national, and regional perspectives about the potential contributions that watershed management can make to the conservation, sustainable development, and use of natural resources in ecosystem-based land stewardship in the 21st century. The conference consisted of 2 and a half days of synthesis papers.

Coastal management at Ojo de Liebre, Baja California Sur

Publications Posted on: October 05, 2012
We analyzed the biotic, abiotic, and human components interacting at the coastal zone of the Ojo de Liebre Lagoon, Baja California Sur, Mexico. Using geographic information systems, satellite images, and the main biological, physical, and socioeconomic components, we developed an environmental characterization of the zone.

Sustaining flows of critical resources: One example (Abstract)

Publications Posted on: October 05, 2012
Growth of communities throughout the west accelerates into the 21st century, resources that were once unseen and unused, except, perhaps, by ranchers, are in increasing demand. This trend is particularly apparent on the Public Land.

A regional plan to protect open spaces, water quality, fish and wildlife habitat (Abstract)

Publications Posted on: October 05, 2012
1978, voters in the Multnomah, Washington, and Clackamas counties approved the creation of the first elected regional government, Metro to oversee land use planning and manage the urban growth boundary, and be consistent with state land use goals.

Attributes of successful stock water ponds in southern Arizona

Publications Posted on: October 05, 2012
The attributes of 20 ponds (or stock tanks) on the Nogales Ranger District of the Coronado National Forest were studied in detail by groups. Two contrasting groups, judged to be either functional (n = 11) or nonfunctional (n = 9) were used in the study. Differences between the groups were evaluated on the basis of attributes of the ponds themselves, the contributing watersheds, and the local climate and modeled hydrology.

Arizona watershed framework in the Verde River watershed

Publications Posted on: October 05, 2012
The Arizona Department of Environmental Quality, Water Quality Division drafted a six-step approach to guide its staff and local participants in developing and implementing watershed management plans. From January 1999 through June 2000, the draft Arizona Statewide Watershed Framework will be tested in Arizona's Verde River watershed.

Burned area emergency watershed rehabilitation: Program goals, techniques, effectiveness, and future directions in the 21st Century

Publications Posted on: October 05, 2012
Following wildfires, burned areas are assessed by special teams to determine if emergency watershed rehabilitation measures are required to restore watershed function and minimize damage to soil resources. The objective of burned area emergency rehabilitation (BAER) treatments is to restore watershed condition and reduce erosional losses on hillslopes, in channels, and on road surfaces and peripheral areas such as ditches.

Soil and vegetation changes in a pinyon-juniper area in central Arizona after prescribed fire

Publications Posted on: October 05, 2012
Prescribed fire has been used as an inexpensive and rapid method for disposing of slash following fuelwood sales in pinyon-juniper sites. Soil heating during a fire has a direct effect on soil nutrients and microbial activity. The potential for understory cover quantity and quality, along with soil nutrient changes should be the determining factors in management decisions to use prescribed fire for slash disposal.

The role of fire in management of watershed responses

Publications Posted on: October 05, 2012
Hydrologic responses of watersheds are strongly related to vegetation and soil disturbances. Many of the storage and transfer components of the global hydrologic cycle are altered by the occurrence of fire. The major effect of fire on the hydrologic functioning of watersheds is the removal of vegetation and litter materials that protect the soil surface.

Wetland storage to reduce flood damages in the Red River

Publications Posted on: October 05, 2012
The restoration of previously drained wetlands to store water was not found to be an economically feasible strategy to reduce flood related damages in two sub-watersheds of the Red River Valley (the Maple River Watershed in North Dakota, and the Wild Rice Watershed of Minnesota). Restoring wetlands, while providing full ecological services, was less feasible, even considering additional (nonflood related) benefits of wetlands.
