Available in PDF, EPUB and Kindle. Book excerpt: Canada has assisted in formulating the scheme for the control of forest reproductive material moving in international trade. The object of the scheme is to encourage production and use of forest tree reproductive materials that have been collected, processed, raised and distributed in a manner that ensures their trueness to name. Forestry Canada is the designated administrative authority for this scheme. Its forestry centres are the responsible certifying authorities. Since certification may protect the seed trade and enhance the value of seed products it is essential that the procedures of seed certification be well defined and strictly applied. The purpose of this manual is to provide practical instructions to ensure that certification procedures are properly executed.

Download or read book The Woody Plant Seed Manual Part I written by Franklin T. Bonner and published by Lulu.com. This book was released on 2015-05-09 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive handbook on the seeds of trees and shrubs produced by the USDA Forest Service was USDA Misc. Pub. 654, Woody-Plant Seed Manual. The manuscript was ready for publication in 1941, but World War II delayed publication until 1948. The boom in tree planting in the 1950s and 1960s created a large demand for seeds and exposed the gaps in our knowledge concerning production and quality of seeds of woody plants in general. The 1974 Handbook proved to be very popular both in this country and abroad, leading to five printings and translations in several other languages. More than a quarter-century after its publication, however, numerous advances in tree seed technology have dictated that a new revision is needed; the result is the current volume. Part I contains information on how to get seeds and raise seedlings. Get Your Copy Now.

Download or read book Pine Wilt Disease A Worldwide Threat to Forest Ecosystems written by Manuel M. Mota and published by Springer Science & Business Media. This book was released on 2008-08-28 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine wilt disease (PWD) is unquestionably a major threat to forest ecosystems worldwide. After seriously affecting Eastern Asian countries, the challenge is now in Europe, following its detection in Portugal in 1999 and its subsequent spread. For foresters, these were really very bad news and, in order for adequate action to be taken, scientists had to teach politicians about the seriousness of the problem. That is never an easy task, but it was successfully done at that time, mainly by the continued effort of Professor Manuel Mota. The challenge of having political decisions based on good science is fundamental for the success of any program, but especially in dif?cult situations such as those arising by the introduction of harmful organisms in new ecosystems. The success of the dialogue between science and policy requires intelligent partners from each side, which is not always necessarily the case... Examples of lack of recognition of problems raised by science are unfortunately abundant throughout the history of science. The recent recognition of the efforts of the Intergovernmental Panel on Climate Change (IPCC) and Al Gore with the - bel Prize, and the continued failure in taking appropriate actions by major political players is a dramatic modern example of the dif?culty of this dialogue...
