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: This problem analysis describes a variety of human-resource interaction issues & identifies related social science R&D needs that serve as the foundation for the Alaska Communities & Forest Environments Team within the Pacific Northwest Research Station. The document lays out a research agenda that focuses on understanding relations between human communities & natural resources. The agenda is divided into four sub-topics: (1) communities in transition; (2) collaborative planning & stewardship; (3) sustainable tourism & outdoor recreation; & (4) cultural orientations to & uses & values of natural resources, including traditional knowledge, indigenous property rights, & tenure systems.

Download or read book Residual Activity of Carbaryl Protected Lodgepole Pine Against Mountain Pine Beetle Dillon Colorado 1982 and 1983 written by Marion Page and published by . This book was released on 1985 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most destructive insect that attacks lodgepole pine (Pinus contorta Dougl.), a species valued for multiple uses throughtout North America. The effective residual life of carbaryl, applied as a 2 percent suspension of Sevimol to the bark of lodgepole pine to prevent attack by mountain pine beetle, was evaluated near Dillon, Colorado. Trees (9,568) treated in 1982 under operational conditions were used to assess the efficacy of the treatment for one and two beetle flight periods after insecticide application. Estimated mortality of untreated trees was 0.91 percent compared with 0.074 percent for trees treated 16 months earlier with carbaryl. Residues of carbaryl were estimated at 359 ppm 16 months after application. When exposed to intense beetle pressure, bolts from trees treated 13 months earlier suffered fewer attacks and had shorter mean egg gallery length than did bolts from untreated trees; bolts from trees sprayed 3 months earlier suffered no attacks. Apparently a 2 percent suspension of carbaryl applied to the bole of lodgepole pine was effective in protecting lodgepole pine from mountain pine beetle for the flight period 3 months after application and even provided protection for a second flight period 16 months after treatment. I The results suggest that protection cost and I insecticide use could be reduced by 50 percent during a 4-year outbreak.

Download or read book Human Impacts to Fire Regime in Interior Alaska written by La'ona DeWilde and published by . This book was released on 2003 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A thorough analysis of human impacts on interior Alaska's fire regime demonstrates that human activities have effects in populated areas. Two approaches were used to determine impacts: I examined three regions with very different populations, and also one large region to analyze suppression, ignition, and vegetation interactions. The Fairbanks Region, with a large human population and an extensive road system, differs from two other regions with low human populations and few roads. In the Fairbanks Region, humans have impacted fire regime by causing more fires in certain fuel types and doubling the length of the fire season. The Fairbanks Region, with a higher level of suppression than the other two regions, has less area of land burn, even after controlling for fuel type and a higher number of human ignitions. In areas designated for high protection, there is less area burned and more human caused starts. For interior Alaska as a whole, human ignitions and suppression have only a minor effect on fire regime, and climate strongly influences the total area burned. However, in populated areas and areas designated for high protection, human ignitions account for most of the area burned, and less area bums overall due to suppression"--Leaf iii.
