Download or read book Generic Forest Health Surveys Guidebook written by British Columbia. Ministry of Forests and published by Ministry of Forests. This book was released on 2001 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guidebook is intended to assist field practitioners in determining forest health issues and the incidence of forest health factors in high-hazard forest ecosystems. The first section describes the attributes of hazard & risk rating and briefly outlines some available hazard & risk rating systems. Section two covers forest development plan-level surveys, and includes procedures for landscape-level forest health factor surveys. Topics covered include aerial overview surveys, classification of damage, map processing, survey for pest incidence, and windthrow risk evaluation. The final section reviews stand-level surveys. Appendices include a glossary, example inventory data & field data forms, and a table of damage agents & associated pest severity ratings.

Available in PDF, EPUB and Kindle. Book excerpt: Effective management of tree health problems depends on early detection and recognition of symptoms. This guide includes 140 photographs of symptoms from more than 50 tree species, which can be used as a basis for demonstrating the effects of pest (biotic) and non-living (abiotic) influences on trees. It is not designed as an identification guide to insect pests and diseases of trees, but rather seeks to enable a preliminary diagnosis and assessment of potential problems, in order to promote better planning and more effective management of forests and trees.

Book excerpt: This manual has been prepared to act as a reference guide for data collection & compilation of stocking and free-growing forest surveys conducted to meet the legal obligations described in the Forest Practices Code of British Columbia Act, the Silviculture Practices Regulation, and the Woodlot Licence Forest Management Regulation. The manual is written to correspond to the chronological sequence in which surveys are conducted, beginning with file review & office preparation, through basic field procedures, to the final survey report that is submitted to the Ministry of Forests. The manual also describes the best management practice for silviculture surveys in British Columbia. Appendices include a glossary, additional details on some field procedures, and a list of links to Ministry field cards & forms.

This book was released on 1997 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the project reported in this document is to review and evaluate the use of remote sensing applications to assess forest health and sustainability. After an introduction discussing the concept of forest health and relationships between stress, strain, and damage, section 2 reviews the factors most likely to cause plant stress, the manner in which the stresses are manifested, and methods for detecting or determining those factors (both environmental and man-made). Section 3 focuses on the manifestations or markers of stress, related factors, and other indicators of health and vigour. This leads to a review of the role of remote sensing technology for supplying such information in section 4, which describes such tools as cameras, imaging spectrometers, satellite-borne sensors, and geographic information technologies. Section 5 reviews applications where remote sensing could contribute to forest health studies, and identifies the most promising technologies. A design framework for forest health monitoring is then outlined, and some general implementation strategies are suggested. Specific project stages and pilot studies are also proposed which are intended to develop essential methodologies or test new approaches to forest health remote sensing. Finally, financial implications of various project options are assessed. The appendix includes discussion of temporal and spatial considerations for monitoring forest health and sustainability.

Download or read book Field Guide to Diseases and Insects of the Rocky Mountain Region written by U.s. Department of Agriculture and published by Createspace Independent Pub. This book was released on 2012-10-19 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This field guide details the most commonly encountered diseases and insects of forest trees in the Rocky Mountain Region. Descriptions of diseases, insects, and physical injuries focus on the most diagnostic features of each. Photographs, line drawings, and tables are used to illustrate and emphasize characteristics described in the text. Diseases and insects in plains hardwood trees are not covered in depth. Ornamental trees are sometimes affected by the diseases or insects included in this guide but may not be specifically mentioned as hosts. This guide presents diseases and then insects. Entries are arranged according to the part of trees typically damaged by the agent described. The disease section describes dwarf and true mistletoes, decays (including root diseases and stem decays), cankers, wilts, rusts, foliage diseases, shoot blights, and abiotic injuries and miscellaneous diseases. The insect section describes bark beetles, defoliators, wood borers, sap-sucking insects, gall formers, mites, and bud and shoot insects. At the end of the guide is a subject index, a host-pest index to damaging agents by tree species and part of the tree affected, and a glossary of terms. The host-pest index provides a rapid means of assessing the number and variety of agents described for each tree species. This field guide applies to the USDA Forest Service's Rocky Mountain Region, which includes Colorado, Wyoming, South Dakota, Kansas, and Nebraska. Additional hosts, diseases, and insect pests may be encountered outside this Region that are not included here, and a few of the diseases and insects included in this guide may not be seen in other areas. Plant pathologists and entomologists are available to assist resource managers with identification of insects and pathogens encountered in the forests.
