History of watershed research in the Central Arizona Highlands

Publications Posted on: August 01, 2018
The Central Arizona Highlands have been the focus of a wide range of research efforts designed to learn more about the effects of natural and human induced disturbances on the functioning, processes, and components of the region's ecosystems.

Priest River Experimental Forest

Publications Posted on: May 11, 2018
Priest River Experimental Forest was among the first experimental forests set aside as a forestry research center in September 1911. The forest served as the headquarters for the Priest River Forest Experiment Station until 1930 when the forest was incorporated into the Northern Rocky Mountain Forest and Range Experiment Station. The forest is currently administered by the Intermountain Research Station.

Drought, tree mortality, and wildfire in forests adapted to frequent fire

Publications Posted on: January 23, 2018
Massive tree mortality has occurred rapidly in frequent-fire-adapted forests of the Sierra Nevada, California. This mortality is a product of acute drought compounded by the long-established removal of a key ecosystem process: frequent, low- to moderate-intensity fire. The recent tree mortality has many implications for the future of these forests and the ecological goods and services they provide to society.

Fuel treatment impacts on estimated wildfire carbon loss from forests in Montana, Oregon, California, and Arizona

Publications Posted on: August 15, 2012
Using forests to sequester carbon in response to anthropogenically induced climate change is being considered across the globe. A recent U.S. executive order mandated that all federal agencies account for sequestration and emissions of greenhouse gases, highlighting the importance of understanding how forest carbon stocks are influenced by wildfire.

Chapter 8: The future

Publications Posted on: June 12, 2009
Research in the vegetation types of the Central Arizona Highlands has evolved, for the most part, from single resource evaluations (increased water yield) to evaluations that consider the multiple benefits of vegetation management treatments. The papers presented in this publication have demonstrated that vegetation can be managed to increase water yields, while providing timber, forage, recreation, wildlife, and other amenities.

Chapter 7: Changing values of riparian ecosystems

Publications Posted on: June 12, 2009
Riparian ecosystems in the Central Arizona Highlands, and throughout the Southwest in general, provided the necessary water for humans, livestock, and agricultural crops during settlement by Europeans in the late 1800s. Other resources available in these moist environments included wildlife and fish, livestock and wildlife forage, and shade. Trees were often used for fuel, poles, and building materials.

Chapter 6: Creating a basis for watershed management in high elevation forests

Publications Posted on: June 12, 2009
Higher mountains and plateaus in the Central Arizona Highlands generally support southwestern mixed conifer forests, associated aspen and spruce-fir forests, and a small acreage of grasslands interspersed among the forested areas.

Chapter 5: Interdisciplinary land use along the Mogollon Rim

Publications Posted on: June 12, 2009
The amount of water stored in the Salt River Project reservoirs during the middle 1950s was low and, as a consequence, apprehension arose among some residents of the Salt River Valley that a serious water shortage would soon occur. Groundwater supplies in the Valley were also being rapidly depleted, and pumping costs were steadily rising.

Chapter 4: Managing chaparral in Yavapai County

Publications Posted on: June 12, 2009
Yavapai County in central Arizona supports extensive stands of chaparral in the Bradshaw Mountains, Mingus Mountain, and the Santa Maria Range. Chaparral occupies about 400,300 acres of the Prescott National Forest (Anderson 1986). These chaparral communities provide a wide range of benefits including watershed protection, grazing for wildlife and domestic animals, recreational opportunities, and wildlife habitat.

Chapter 3: Providing water and forage in the Salt-Verde River Basin

Publications Posted on: June 12, 2009
The Salt-Verde River Basin, covering about 8.4 million acres of the Central Arizona Highlands, supplies most of the water for the Salt River Valley in addition to providing other multiple use values. Mixed conifer, ponderosa pine forests, and a portion of the pinyon-juniper woodlands predominantly occupy the higher-elevation watersheds.
