Wildland Fire on Ecosystems: Effects of Fire on Air
ISBN: 9781973808039 / Angielski / Miękka / 2017 / 88 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Wildland fire is an integral part of ecosystem management and is essential in maintaining functional ecosystems, but air pollutants emitted from those fires can be harmful to human health and welfare. Because of the public and governmental concerns about the possible risk of wildland fire smoke to public health and safety, as well as nuisance, visibility, ozone generation, and regional haze impacts, increasingly effective smoke management programs and air quality policies are being implemented with support from research and land management agency programs. This state-of-knowledge review of...

Christmas Tree Pest Manual (Third Edition)
ISBN: 9781782667391 / Angielski / Miękka / 2014 / 164 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. The newest edition is published by the U.S. Forest Service, Northeastern Area State and Private Forestry. This edition includes a number of new pests, many of them found on fir Christmas trees. The original manual had a strong emphasis on Scotch pine. Most of the original pest descriptions remain in the manual; however, given that Christmas tree growers are growing more fir and other species, new pest problems needed to be addressed.

Modeling Wind Adjustment Factor and Midflame Wind Speed for Rothermel's Surface Fire Spread Model
ISBN: 9781480172197 / Angielski / Miękka / 2012 / 44 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Rothermel's surface fire spread model was developed to use a value for the wind speed that affects surface fire, called midflame wind speed. Models have been developed to adjust 20-ft wind speed to midflame wind speed for sheltered and unsheltered surface fuel. In this report, Wind Adjustment Factor (WAF) model equations are given, and the BehavePlus fire modeling system is used to demonstrate WAF calculation and effect on modeled fire behavior. There are differences in implementation of the same basic wind adjustment models in various fire behavior applications, including the Fireline...

Managing Gambel Oak in Southwestern Ponderosa Pine Forests: The Status of Our Knowledge
ISBN: 9781480144460 / Angielski / Miękka / 2012 / 34 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Gambel oak (Quercus gambelii) is a key deciduous species in southwestern ponderosa pine (Pinus ponderosa) forests and is important for wildlife habitat, soil processes, and human values. This report (1) summarizes Gambel oak's biological characteristics and importance in ponderosa pine forests, (2) synthesizes literature on changes in tree densities and fire frequencies since Euro-American settlement in pine-oak forests, (3) suggests management prescriptions for accomplishing various oak management objectives (for example, increasing diameter growth or acorn production), and (4) provides an...

Wilderness Visitor Experiences: Progress in Research and Management: 2011 April 4-7; Missoula, MT
ISBN: 9781480198760 / Angielski / Miękka / 2012 / 226 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. The Wilderness Visitor Experience Workshop was held at the Lubrecht Experimental Forest near Missoula, MT, April 4-7, 2011. The science and management of wilderness visitors is now more than half a century old. Much has been learned over this period. And yet it seems that enthusiasm for recreation research generally and for wilderness visitor science specifically has been waning recently. With the 50th Anniversary of The Wilderness Act approaching in 2014, it seemed timely to celebrate and capture what has been learned over the past 50 years. We also wanted to revitalize this research...

Wildland Fire in Ecosystems: Effects of Fire on Soil and Water
ISBN: 9781480199118 / Angielski / Miękka / 2012 / 260 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Fire is a natural disturbance that occurs in most terrestrial ecosystems. It is also a tool that has been used by humans to manage a wide range of natural ecosystems worldwide. As such, it can produce a spectrum of effects on soils, water, riparian biota, and wetland components of ecosystems. Fire scientists, land managers, and fire suppression personnel need to evaluate fire effects on these components, and balance the overall benefits and costs associated with the use of fire in ecosystem management. This publication has been written to provide up-to- date information on fire effects on...

Recreation Visitor Research: Studies of Diversity
ISBN: 9781481140294 / Angielski / Miękka / 2012 / 222 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. In 1987, the Pacific Southwest Research Station (PSW) of the U.S. Department of Agriculture Forest Service (USFS) chartered a research work unit to examine outdoor recreation in the wildland-urban interface. The new work unit was established to address the needs of the increasingly diverse recreation visitors to national forests. The four forest supervisors in southern California observed that in the past, most recreation visitors were White. However, that percentage was changing with an increase in diverse visitors. In particular, they noted the increasing numbers of Latino visitors. They...
