A results-based system for regulating reforestation obligations: Some developments in 2003

In a recent paper, we described a multi-block approach to the regulation and management of reforestation (P.J. Martin, S. Browne-Clayton, and E. McWilliams (2002), "A results-based system for regulating reforestation obligations," Forestry Chronicle 78(4): 492–498). Under the multi-block approach, indicators are devised that portray the degree to which the condition of regeneration on harvested areas is consistent with forest management goals. A population of harvested areas is sampled. The current levels of the indicators are estimated and compared to threshold values. If observed levels exceed threshold levels, the population is considered adequately reforested and all reforestation obligations are met. In this paper, we describe some recent enhancements of this concept and demonstrate how the multi-block approach provides characteristics desirable in a regulatory regime. By shifting the focus of reforestation regulation from the stand level to the level of a population of harvested areas, the multi-blo...
