The Southwest Watershed Science Team of the Rocky Mountain Station's Air, Water and Aquatic Environments Science Program, and the Team’s predecessor (Watersheds and Riparian Ecosystems of Forests and Woodlands in the Semi-Arid West), have been involved in research on the Upper Verde River since 1993. 

The key roles of four Experimental Forests in the LTSP International Research Program

Publications Posted on: March 23, 2015
Four Experimental Forests were pivotal in piloting the long-term soil productivity (LTSP) cooperative research program - one of the most successful and extensive collaborative science efforts yet undertaken by the USDA Forest Service. Launched on the Palustris, Challenge, Marcell, and Priest River Experimental Forests, LTSP traces to a seminal discussion during a field tour in central Louisiana in 1986. P. E.

EFRs in the Rocky Mountain Research Station: Understanding patterns of forest growth, weather and disturbance [Chapter 2.8]

Publications Posted on: October 02, 2014
How does forest growth integrate weather, insect and disease attach, management actions, and natural disturbance? Which of these has the most impact on forest growth, composition, structure, and change? These questions have animated the activities of scientists of the Rocky Mountain Research Station (RMRS) since its earliest days, and continue to animate our research today.

Soil temperature and moisture dynamics after experimental irrigation on two contrasting soils on the Santa Rita Experimental Range: Implications for mesquite establishment

Publications Posted on: August 24, 2010
We established a large-scale manipulative experiment in a semidesert grassland on the Santa Rita Experimental Range to determine how the recruitment and physiology of woody plants (Prosopis velutina Woot.) are affected by invasive grasses, seasonal precipitation regimes, and underlying soil characteristics.

Spectral reflectance and soil morphology characteristics of Santa Rita Experimental Range soils

Publications Posted on: August 24, 2010
The Santa Rita Experimental Range (SRER) soils are mostly transported alluvial sediments that occur on the piedmont slope flanking the Santa Rita Mountains in Arizona. The major geomorphic land forms are alluvial fans or fan terraces, but there are also areas of residual soils formed on granite and limestone bedrock, basin floor, stream terraces, and flood plains.

Sweet resin bush (Euryops subcarnosus DC ssp. vulgaris B. Nord; or, Euryops multifidis (L. f.) DC.), a South African shrub introduced to Arizona in the 1930s, was discovered on the Santa Rita Experimental Range (SRER) in 1998.

Soil and ecological sites of the Santa Rita Experimental Range

Publications Posted on: August 24, 2010
A soil survey and rangeland resource inventory of the Santa Rita Experimental Range (SRER) was conducted by staff from the Tucson office of the Natural Resources Conservation Service (NRCS) during April and May of 1997. Thirty-two soils series and taxadjuncts were mapped on the SRER and delineated in 24 different mapping units.

Historical and recent flora of the Santa Rita Experimental Range

Publications Posted on: August 24, 2010
The historical flora of the Santa Rita Experimental Range was composed from historical lists of plants collected by various investigators since 1903. Plant accessions were verified from lists of plant specimens housed at the Rocky Mountain Research Station herbarium in Flagstaff, AZ, and the Rocky Mountain National Herbarium in Laramie, WY.
