Begins with a literature review on the habitat, reproduction and establishment, and stand development of black spruce. This is followed by a review of thinning as a silvicultural system, and thinning of black spruce in particular. Concludes with a report of a case study of the growth response of black spruce to various levels of thinning. The study area had been burned by wildfire and is located in the Tyrol Lake Demonstration Forest near Lake Nipigon, Ontario.
ECOLOGICAL SILVICULTURAL SYSTEMS Unleash the natural power and adaptability of forests with this cutting-edge guide For generations, silvicultural systems have focused largely on models whose primary objective is the production of timber, leading to drastically simplified forests with reduced ecological richness, diversity, and complexity. Ecological silviculture, by contrast, focuses on producing and maintaining forests with “all their parts”—, that is, with the diversity and flexibility to respond and adapt to global changes. Ecological silviculture seeks to emulate natural development models and sustain healthy forests serving multiple values and goals. Ecological Silvicultural Systems provides a comprehensive introduction to these approaches and their benefits tailored to diverse types of forests, designed for forest management professionals. It provides a series of exemplary models for ecological silviculture and surveys the resulting forest ecosystems. The result is a text that meets the needs of professionals in forestry and natural resource management with an eye towards sustaining healthy forest ecosystems, adapting them to climate change, protecting them from invasive species, and responding to changing market forces. Ecological Silvicultural Systems readers will also find: Detailed treatment of forest ecosystems in North America, Europe, South America, and Australia A broad field of contributors with decades of combined expertise on multiple continents Discussion of pine woodlands; temperate hardwood forests, boreal forests, temperate rainforests, and more Ecological Silvicultural Systems is a useful reference for professional foresters, wildlife habitat managers, restoration ecologists, and undergraduate and graduate students in any of these fields.
Begins with a literature review on the habitat, reproduction, seedbed requirements, and growth of black spruce, and continues with an overview of black spruce silvicultural systems for Ontario upland sites. Research needs and management considerations are then outlined. Concludes with reports on two case studies of black spruce silviculture at the Leo Vidlak Demonstration Forest near Raith, Ontario. The first study involved two-stage harvesting as an alternative to clear-cutting, and the second explored natural regeneration in stands without advance growth.
After an introduction on stand thinning objectives and methods, this report gives an overview of the habitat and growth characteristics of jack pine and presents a literature review of jack pine thinning. Research needs regarding thinning operations in Ontario and management considerations for jack pine are also outlined. The report concludes with a case study conducted to demonstrate commercial thinning of jack pine with a single grip harvester. The study was carried out at the Seine River Demonstration Forest in north-west Ontario.
