Effects of a range of biomass removals on long-term productivity of jack pine ecosystems: establishment report.

The long-term loss of forest site productivity is a major concern to associated industries, governments, and the public at large. The establishment of a series of experimental and chronosequence sites, in a range of Plonski's site classes, in north central Ontario jack pine (Pinus banksiana) ecosystems is documented. Baseline data collection methods including pre- and postharvest stand and site characteristics; tree, understorey, woody debris, and forest floor biomass sampling; and vegetation, seedbed, and natural regeneration assessments are presented. This framework will provide opportunities to study the effects of present day forest harvest and site preparation practices on long-term site productivity as well as on vegetation dynamics, succession, and biomass accretion in jack pine ecosystems.
