  1. Vegetation Management Alternatives Section IV.What are the social Issues associated with using silviculturally effective alternatives? Dr. Stephen Wyatt Université de Moncton, campus d'Edmundston

  2. What are the cost implications? What are the social Issues? • This section will summarize of the social issues associated with the use of vegetation management alternatives. • Published literature will be reviewed and summarized.

  3. Vegetation Management Alternatives Section V. What are the cost implications of silviculturally effective alternatives? F. Wayne Bell, Jenn Dacosta, Andree Morneault, Bill Towill, John Winters, and Al Stinson, Ontario Ministry of Natural Resources Chander Shahi, Krishna Homagain, Nancy Luckai, and Jason Dampier, Lakehead University Magaret Penner, Forest Analysis Ltd.

  4. What are the cost implications?Background Very few studies have examined the cost effectiveness of vegetation management alternatives in North American boreal forests.

  5. What are the cost implications?Approach Stand level analysis • Stage I: Collect field data and develop longer-term growth models • Stage II: Benefit-cost analysis (BCA)

  6. What are the cost implications?Stage I – Growth and Yield • Six studies, 14 site/treatment combinations with 100 experimental units • Located across the Planning Area of Ontario • Include white spruce, black spruce, and jack pine • Established between 1990 and 1994

  7. What are the cost implications?Stage I – Growth and Yield • Six studies, 14 site/treatment combinations with 100 experimental units • Include white spruce, black spruce, and jack pine • Established between 1990 and 1994

  13. What are the cost implications?Stand-level Modeling • Inputs were compiled by study and treatment • For plantations the inputs were taken from the data collection and include planted stock species, density and Dbhq and ingress species composition, density and Dbhq. • Projections using yield curves are based on empirical relationships fit to data collected from permanent sample plots in Ontario and Quebec (Penner et al., 2008). • Gross merchantable volumes were calculated using the minimum standards in the Ontario Ministry of Natural Resources scaling manual (OMNR, 1995).

  14. What are the cost implications?Stage II – Economic Analysis Benefit-Cost Ratio (BCR) - present value of the benefits expected throughout the life of a management option or project, divided by the present value of the costs That is:
