This book was released on 1984 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simulation model was developed to estimate postfire changes in the production and value of grazing lands in the Northern Rocky Mountain-Intermountain region. Ecological information and management decisions were used to simulate expected changes in production and value after wildfire in six major rangeland types: permanent forested range (ponderosa pine), transitory range (Douglas-fir, larch, lodgepole pine, western white pine), mountain grassland, sagebrush, pinyon-juniper, and western hardwoods. Changes varied widely in quantity and duration among the range types. The largest decrease in net value was calculated for mountain grassland ($7/acre for a 2-year period). The largest increase in net value was calculated for a ponderosa pine sawtimber stand with 100 percent basal area removal ($36/acre for a l50~year period). The estimates calculated in this study should be useful in land and fire management planning in the Northern Rocky Mountain-Intermountain area.

Book Synopsis Big Sagebrush by : Bruce Leigh Welch
Download or read book Big Sagebrush written by Bruce Leigh Welch and published by . This book was released on 2005 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pioneers traveling along the Oregon Trail from western Nebraska, through Wyoming and southern Idaho and into eastern Oregon, referred to their travel as an 800 mile journey through a sea of sagebrush, mainly big sagebrush ( Artemisia tridentata). Today approximately 50 percent of the sagebrush sea has given way to agriculture, cities and towns, and other human developments. What remains is further fragmented by range management practices, creeping expansion of woodlands, alien weed species, and the historic view that big sagebrush is a worthless plant. Two ideas are promoted in this report: (1) big sagebrush is a nursing mother to a host of organisms that range from microscopic fungi to large mammals, and (2) many range management practices applied to big sagebrush ecosystems are not science based.

Download or read book Countering Misinformation Concerning Big Sagebrush written by Bruce Leigh Welch and published by . This book was released on 2003 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the scientific merits of eight axioms of range or vegetative management pertaining to big sagebrush. These axioms are: (1) Wyoming big sagebrush (Artemisia tridentata ssp.wyomingensis) does not naturally exceed 10 percent canopy cover and mountain big sagebrush (A.t.ssp.vaseyana) does not naturally exceed 20 percent canopy cover; (2) As big sagebrush canopy cover increases over 12 to15 percent, bare ground increases and perennial grass cover decreases; (3) Removing, controlling, or killing big sagebrush will results in a two or three or more fold increase in perennial grass production; (4) Nothing eats it; (5) Biodiversity increases with removing, controlling, thinning, or killing of big sagebrush; (6) Mountain big sagebrush evolved in an environment with a mean fire interval of 20 to 30 years; (7) Big sagebrush is an agent of allelopathy; and (8) Big sagebrush is a highly competitive, dominating, suppressive plant species.

Book Synopsis Changes in Recreation Values After Fire in the Northern Rocky Mountains by :
Download or read book Changes in Recreation Values After Fire in the Northern Rocky Mountains written by and published by . This book was released on 1985 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in recreation values after wildfire in the northern Rocky Mountains were determined by estimating the difference in the present net value of recreation activity with and without fire. To estimate the value of recreation activity at burned and unburned sites, a contingent market valuation approach was used. Hypothetical market transactions were created by soliciting bids from recreationists, which they based on phorographs of recreation sites depicting scenes before and after two kinds of fire--one of low intensity and the other of high intensity. They were asked what they would pay for the situation they most preferred. The results suggest that net value changes in recreation resources are generally low, and possibly insignificant in economic efficiency analyses of fire management programs.

Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.
