Download or read book Introduction to Forest and Shade Tree Insects written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehenisive text approaches the subject from an ecological/evolutionary biological perspective. The assumption is that one cannot study forest insects without understanding the dynamics of the relationship between an insect and its host plant. This relationship includes knowing what factors control forest insect populations such as food, food quality, tree vigor, host selection, and symbiotic relationships. The authors also discuss tree-injuring insects from the perspective of their influence on tree physiology and growth as well as economic and commercial effects. The book represents a "modern" approach to the topic of forest and shade tree insects; is well-illustrated; and includes a comprehensive primary reference list.

Download or read book Hardwood Reforestation and Restoration written by Daniel Gagnon and published by MDPI. This book was released on 2019-04-25 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardwood-dominated temperate forests (mostly in Eastern North America, Europe, North East Asia) provide valuable renewable timber and numerous ecosystem services. Many of these forests have been subjected to harvesting or conversion to agriculture, sometimes over centuries, that have greatly reduced their former extent and diversity. Natural regeneration following harvesting or during post-agricultural succession has often failed to restore these forests adequately. Past harvesting practices and the valuable timber of some species have led to a reduction in their abundance. The loss of apex predators has caused herbivore populations to increase and exert intense browsing pressure on hardwood regeneration, often preventing it. Particularly important are fruit, nut and acorn bearing species, because of their vital role in forest food webs and biodiversity. Restoring hardwood species to natural forests in which they were formerly more abundant will require a number of forest management actions (e.g., resistant hybrids, deer exclosures/protectors, enrichment planting, underplanting, etc.). Similarly, reforesting areas that were once natural forests will also require new silvicultural knowledge. Global warming trends will intensify the need for interventions to maintain the diversity and function of temperate hardwood forests, as well as for increase hardwood reforestation.
