Download or read book Evaluation of Management Techniques to Reduce Sequoia Pitch Moth Damage at Bigfork and Plains Tree Improvement Areas written by Nancy J. Sturdevant and published by . This book was released on 2017 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequoia pitch moth, Synanthedon sequioiae (SPM), can cause significant damage to primarily lodgepole and ponderosa pine trees growing in seed orchards and tree improvement areas, and occasionally in natural forest settings. Management options for SPM in high-value seed orchards are limited. Insecticides have not proven useful in controlling attacks by SPM. Control efforts are mainly accomplished by manually removing larvae from pitch masses on individual trees which is very labor intensive and only partially effective. SPM has a two-year life cycle in Montana and any control method applied needs to be done at a minimum for two-years.

Sturdevant and published by . This book was released on 2016 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequoia pitch moth, Synanthedon sequoiae (SPM), attacks primarily lodgepole and ponderosa pine trees growing in seed orchards, tree improvement areas, and natural forest settings. SPM incidence and damage is usually higher at genetic test sites than in natural forest settings because trees in genetic tests are often growing off-site, which can stress and predispose them to insect and disease problems. Attacks from SPM can weaken trees, cause branch break-offs and even tree mortality when attacks result in girdling. SPM has a two-year cycle in Montana and Idaho.

Download or read book Damselflies of Alberta written by John Acorn and published by University of Alberta. This book was released on 2004-09-21 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: With iridescent blues and greens, damselflies are some of the most beautiful flying insects as well as the most primitive. As members of the insect order Odonata they are related to dragonflies but are classified in a separate suborder. These aquatic insects are a delight to the eye and a fascinating creature of study. In Damselflies of Alberta, naturalist John Acorn describes the twenty-two species native to the province. Exhaustively researched, yet written in an accessible style, the author's enthusiasm for these flying neon toothpicks is compelling. More than a field guide, this is a passionate investigation into one of nature's winged marvels of the wetlands.

Download or read book Hydrological and Biological Responses to Forest Practices written by John D. Stednick and published by Springer Science & Business Media. This book was released on 2007-12-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alsea Logging and Aquatic Resources Study, commissioned by the Oregon Legislature in 1959, marked the beginning of four decades of research in the Pacific Northwest devoted to understanding the impacts of forest practices on water quality, water quantity, aquatic habitat, and aquatic organism popu- tions. While earlier watershed research examined changes in runoff and erosion from various land uses, this study was the first watershed experiment to focus so heavily on aquatic habitat and organism response to forest practices. The Alsea Watershed Study, as it came to be known, extended over 15 years with seven years of pretreatment calibration measurements, a year of treatment, and seven years of post-treatment monitoring. The research was a cooperative effort with scientists from Oregon State University, Oregon Department of Fish and Wildlife, the U.S. Geological Survey, and the U.S. Environmental Protection Agency. Cooperating landowners included the Georgia-Pacific Corporation, the U.S. Forest Service, and a local rancher. It was a remarkable 15-year partnership marked by excellent cooperation among the participants and outstanding coordination among the scientists, many of whom participated actively for the entire period.

Book excerpt: "This conference brought together scientists and managers from federal, state, and local agencies, along with private-sector interests, to examine key concepts involving sustainable ecological systems, and ways in which to apply these concepts to ecosystem management. Session topics were: ecological consequences of land and water use changes, biology of rare and declining species and habitats, conservation biology and restoration ecology, developing and applying ecological theory to management of ecological systems and forest health, and sustainable ecosystems to respond to human needs. A plenary session established the philosophical and historical contexts for ecosystem management."--Title page verso.

Download or read book Wildland Fires and Air Pollution written by Andrzej Bytnerowicz and published by Elsevier. This book was released on 2008-10-06 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between smoke and air pollution creates a public health challenge. Fuels treatments proposed for National Forests are intended to reduce fuel accumulations and wildfire frequency and severity, as well as to protect property located in the wild land-urban interface. However, prescribed fires produce gases and aerosols that have instantaneous and long-term effects on air quality. If fuels treatment are not conducted, however, then wild land fires become more severe and frequent causing worse public health and wellfare effects. A better understanding of air pollution and smoke interactions is needed in order to protect the public health and allow for socially and ecologically acceptable use of fire as a management tool. Wildland Fires and Air Pollution offers such an understanding and examines innovative wide-scale monitoring efforts (field and remotely sensed), and development of models predicting spatial and temporal distribution of air pollution and smoke resulting from forests fires and other sources.
