Download or read book Saproxylic Beetles written by Jörn Buse and published by Andersen Press (UK). This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The group of saproxylic beetles consists of thousands of different species exhibiting a rich variety of form as well as varied life-cycle strategies. They play an important role in decomposition processes and thus for nutrient-cycling in natural ecosystems. Based on contributions given at the conference this book contains contributions about research on conservation ecology of saproxylic beetles as well as results from recent faunistic surveys in different European regions. It comprises aspects of saproxylic beetle ecology, faunistics, diversity and conservation issues. International experts report on their activity, management strategies and new approaches in saproxylic insect conservation. There are a lot of people doing research on saproxylic beetles in different countries of the world, but this seems to be a little bit disorganized. Hopefully, these European conferences will lead to a better, more international network. The contributions included in this volume cover a broad spectrum of research on saproxylic beetles, organized in three main chapters: "Saproxylic beetle assemblages and regional surveys" include "Oaks in Norway," showing the abundance and composition of red-listed species of beetles in hollow oaks. Further reports on regional surveys deals with a spruce primeval forest in Romania, a hardwood floodplain forest in the Czech Republic, and the Gartow region of Lower Saxony, a hotspot of saproxylic beetle diversity in north-western Germany. "Saproxylic beetle ecology and implications for their conservation" deals with ecological studies of single species, e.g. Limoniscus violaceus, Lucanus cervus, Osmoderma eremita and the worldwide distribution of the genus Cucujus. "Advances in methodology and databases" discusses new techniques in trapping and the development of databases. This volume gives a nice overview of the actual research on saproxylic beetles in Europe and I wish the next conference in 2010 a successful meeting; maybe some people from the UK or even overseas should be invited.

Download or read book Review of Log Sort Yards written by John Rusty Dramm and published by . This book was released on 2002 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a general overview of current log sort yard operations in the United States, including an extensive literature review and information collected during on-site visits to several operations throughout the nation. Log sort yards provide many services in marketing wood and fiber by concentrating, merchandising, processing, sorting, and adding value to logs. Such operations supply forest products firms with desired raw materials, which helps improve their bottom line by reducing the number of marginal logs processed. Ultimately, sorting logs leads to better use of the available timber resources. Successful log sort yards are self-sufficient and have well-established markets and a steady supply of wood. Log sort yard concepts and analyses described in this report have broad applications.

This book was released on 1975 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The forest manager must balance all the interacting and often conflicting factors influencing residue management and decide on the best course of action. He needs to determine optimum volume, size, and arrangement of residues to leave on an area after logging, then to select the harvesting methods and residue management alternatives that best provide these conditions. Cramer (1974) summarized environmental effects of forest residues management for major forest types in the Pacific Northwest, but types of treatment were not listed and only minor attention was given to hemlock-spruce forests. Residue management guidelines have been prepared for Oregon and Washington (Pierovich et al. 1975) but the hemlock-spruce type is not discussed as a separate entity. Alaska is not included in either report. This report provides a detailed look at residue management throughout the north Pacific coastal fog belt, including Oregon, Washington, British Columbia, and Alaska. The approach is a general look at forest residues as part of the ecosystem, then a closer look at dead and decaying material after logging, considering fire hazard and the silvicultural, physical, chemical, and esthetic effects of this material. Residue treatments are described, evaluated, and recommended. The report is intended to provide an improved scientific framework for management decisions. The coastal environment is more moist than other parts of the Pacific Northwest. Generally, fire danger is low and the need for residue treatment to reduce fire hazard is limited to special situations. Northward into Alaska, increasing summer precipitation relegates fire danger to a subordinate management problem. Hemlock-spruce residue volumes may range up to 250 tons per acre (560 metric tons per hectare) when an old-growth timber stand is defective and has a high proportion of western red cedar, but volumes may be less than 50 tons per acre (112 metric tons per ha) with more complete utilization of sound young timber. The trend is to less residue volume as defective timber is replaced by vigorous young stands and utilization improves. Residues often dominate the post-logging environment and are a major factor influencing forest regeneration. Fresh residue intercepts natural seed fall or aerially sown seed and prevents seedling establishment; but later, as it decays and with moisture present, it becomes a suitable seed bed for hemlock and spruce. Advance regeneration, usually hemlock, grows on decaying residue material and almost invariably is intermixed with fresh logging residue. Its fate is determined by residue treatment. When residue treatments expose mineral soil, they influence species composition favoring several species. These ecological relationships between forest residues and conifer seedlings can be used by forest managers to influence density and species composition of the new timber stand. A common problem in hemlock-spruce is too many seedlings. When advance regeneration is prolific, harvesting plans and residue treatments should be designed to destroy some of the seedlings. Overstocking with post-logging regeneration can be reduced if the logging operation is planned so that fresh slash covers an appropriate portion of suitable seed beds. In special situations, individual factors carry heavy weight in residue management decisions. For soils with high erosion potential, a protective mantle of organic material should be left. At least the small residue material should be left on nutrient-deficient soils to add to the nutrient capital. Residue should be kept out of stream channels. In Oregon and Washington, broadcast burning of residues in heavy brush areas helps to control the brush and open up the area for planting. Mistletoe-infested seedlings should be classed as residue and destroyed as part of disease control programs. Special attention should be given to residue management in recreation and scenic areas. Large, continuous areas of logging slash should be avoided because of fire hazard. Smoke management plans should be followed. Treatments are needed when residue volume is too great, because the residue will interfere with seedling establishment and intensive management of the new stand.
