Spatial accuracy assessment in natural resources and environmental sciences: Second International Symposium

This international symposium on theory and techniques for assessing the accuracy of spatial data and spatial analyses included more than ninety presentations by representatives from government, academic, and private institutions in over twenty countries throughout the world.

Biomass flow in western forests: Simulating the effects of fuel reduction and presettlement restoration treatments

Fuel treatment silviculture and the resulting long-term flow of biomass were examined using data from selected western stands. An uneven-aged management regime with reserve trees was modeled, using a canopy closure of 40 percent for the dominant trees as a target and a harvest cutting cycle of 20 years. Fuel reduction treatments in currently overstocked stands resulted in an initial peak of removal for the first and second cutting cycles.

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

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.

Capturing subregional variability in regional-scale climate change vulnerability assessments of natural resources

Natural resource vulnerability to climate change can depend on the climatology and ecological conditions at a particular site. Here we present a conceptual framework for incorporating spatial variability in natural resource vulnerability to climate change in a regional-scale assessment. The framework was implemented in the first regional-scale vulnerability assessment conducted by the US Forest Service.

Coming to a landscape near you: Natural resource changes in the Interior West

In the coming decades, population growth, economic growth, and associated land-use changes - in concert with climate change - will influence forests and rangelands in the Interior West. Society’s demand for ecosystem goods and services continues to increase as human and biophysical change alter the productive capacity of these lands.

Cross border waters: Fragile treasures for the 21st Century; Ninth U.S./Mexico Border States Conference on Recreation, Parks, and Wildlife; 1998, June 3-6

This conference brought together scientists and resource managers from government, universities, and private organizations in the United States and Mexico. In a continuing international forum, participants exchanged information on existing or potential cooperative projects, agency functions and programs, and issues were concerning natural and cultural resource management in the border states.

Coastal management at Ojo de Liebre, Baja California Sur

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)

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)

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

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.
