Old Growth-Can The Conflicts Be Resolved?

Reference No:

GIS 12-1

Old growth is a hot topic these days, one of the hottest in the resource management arena. How do we use natural resources in a way which sustains natural productivity while meeting the needs of mankind today and in the future?

Although most of British Columbia is forested and much of the province's forest cover is still in an old growth or mature condition, old growth forests are considerably reduced from their original extent and cannot be reproduced under currently prevailing forestry practices.

Old growth is fundamentally an ecological concept, and British Columbia's old growth forests generally conform to conceptual and ecological definitions, but they do not necessarily satisfy existing mensurational and structural criteria, especially in interior zones and at higher elevations.Three representatives of business, government and an environmental group discuss the fundamental issues in this videotaped debate.

Should characterization of old growth be done within the context of an ecological classification, and by using multiple criteria including age, size, disturbance, stand composition, structure, function , minimum area, etc. Development of working definitions for the various old growth forest types is the first requirement for a comprehensive research and management strategy for old growth.

Mapping Potential Old Growth Forests and Other Resources on National Forest and Park Lands In Oregon and Washington

Reference No:

GIS 12-2

The project is divided into several phases, including: (1) production of a GIS database and map of potential old growth forest lands; (2) production of detailed GIS data layers, based on slope, aspect, elevation, hydrology, flight line map, location of research and inventory plots, training site location, crown closure, species, size/class structure, vegetation type, and plant association groups. Methods developed to complete this project are: image classification, polygon creation and accuracy assessment.
