This book was released on 1994 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report providing a subjective assessment of the scope, applicability, and overall reliability of existing published references related to natural regeneration of white, Engelmann, and black spruce in North America and a synopsis of references on the subject. The references are listed alphabetically by author for each of 563 references, based on a dBASE IV database coded according to 105 keywords. The database allows the user to search geographically, by species of spruce, by forest section within Canada, or by any of the keywords listed. The emphasis is on white spruce in a boreal mixedwood setting but also includes information on natural regeneration of Engelmann spruce and upland black spruce, plus a limited amount of Norway spruce. Most of the references are from the 1990s.

Download or read book Alternative Silvicultural Systems for Ontario s Boreal Mixedwoods written by Christopher Herbert Richard Wedeles and published by Sault Ste. Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1995 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarises the potential use of alternative silvicultural (harvesting) systems on the productivity of boreal mixedwood forests. Begins with an overview of the ecology of boreal mixedwoods, including physical environment, stand dynamics, and landscape ecology; then provides detailed reviews of modified clear-cutting systems (including strip cutting, patch cutting, and seed-tree cutting), shelterwood systems, and selection systems (including group selection and individual tree selection). Also briefly discusses the environmental considerations that are associated with these systems (effects on soil, water resources, wildlife, and aesthetics). Concludes with a discussion of areas of uncertainty in the application of alternative systems and the perceived problems that have limited their use in boreal mixedwoods.

This book was released on 2001 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bibliography was produced to assist foresters and scientists interested in modelling boreal forest succession at broad scales. It contains more than 600 citations describing existing knowledge on succession in North American boreal forests, and the current state-of-knowledge in modelling succession, with particular emphasis on broad scales. References on succession in boreal forests are grouped by geographic and taxonomic categories. This bibliography also provides information on theories and concepts of succession modelling, issues of scale in modelling succession, the spatial process of propagule dispersal, and the probalistic modelling of forest succession. An author index is provided to help users located citations of interest.
