This book was released on 2018-08-14 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Forest Insect and Disease Situation, Lake States, 1956 Insects and disease play an important part in the reduction of our vast forest resource. Each year they cause large losses in timber growth and result in tree mortality. But that is not all: These agents attack the forest from seed to finished product. Stocking levels are lowered, growth is retarded, and trees are deformed, thus reducing both quality and quantity of forest products. The protection of our forests against these destructive agents is the responsibility of everyone concerned with the national economy.

Download or read book Forest Insect Conditions in the Southeast During 1957 Classic Reprint written by William F. McCambridge and published by Forgotten Books. This book was released on 2018-09-10 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Forest Insect Conditions in the Southeast During 1957 Forest insect conditions continued to improve generally in the South east during 1957 (fig. 1) despite the fact that Ips beetles killed an estimated 10 million board-feet during one epidemic period and southern pine beetles destroyed over trees in the Southern Appalachian Mountains. Extremely cold weather in December killed a high percentage of southern pine beetle broods. The black turpentine beetle remained in outbreak status on the Hoffman Forest in eastern North Carolina. In Florida the beetle was much less active than in 1956. The elm spanworm (snow-white linden moth) was the only defoliator in outbreak status, although local infestations of sawflies, especially in Florida, were causing some concern. During 1957 a cooperative insect survey plan for Florida was developed and two semi-annual aerial surveys conducted. These surveys were under the direction of the Florida Forest Service, with the State Plant Board and U. S. Forest Service cooperating. During these surveys over ten million acres of forest land in northern Florida were covered by2.5-percent intensity. The summary of insect conditions presented in this report includes only those infestations which caused, or were capable of causing, serious economic losses. A few minor insects of special interest are also noted. This report is made up to a considerable extent from information submitted directly to this office by cooperators and from reports and information submitted by pest control foresters, especially from Virginia and North Carolina. The summary of formal cooperative reports is presented in table 1. While the number of reports received by this Station in 1957 is less than those submitted in 1956 insect conditions during the year were under much greater scrutiny. In Virginia, field reports from each district are summa rized monthly by the insect and disease specialist in the Division of Forestry. Copies of these reports are submitted to this office. In addition, the associate extension entomologist puts out a monthly economic insect report containing a section devoted to forest insects. A somewhat similar but less formal system exists in North Carolina, and this office is kept informed of all serious infesta tions by frequent written and verbal communication. The State of Florida israpidly developing an extensive reporting system and this year has developed an intensive aerial sampling survey for the detection of insect infestations and for an appraisal of insect losses.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
