A moratorium was placed on harvesting in the interior Douglas-fir dm2 variant in the E. Kootenay Trench in 1993, due to shortfalls in attaining old growth targets. This deferral protected stands from harvest, but did not ensure the maintenance of historic old growth structure, composition and ecological function. Therefore 2 sites were released from the moratorium for restoration treatments in 1995, and treatments were undertaken to modify the stocking levels, species composition, and the understory to approximate pre-settlement stand conditions, using partial cutting and prescribed fire on a regular cycle. This particular project entailed setting up permanent sample plots and collecting monitoring data in one of the sites (Strauss Road) order to monitor the rate of overstory release, the success of the underburn at effecting desirable plant community and species shifts, the rate and quantity of conifer ingress, and the maintenance, recruitment and use of wildlife trees and wildlife tree patches. Data collection was done in 30 hectares of treated area, and 30 hectares of control area, using the Permanent Sample Plot protocol (BCMOF 2000). This monitoring is necessary to determine the success of the treatments and the timing of further treatments. This project was a priority for the MOF because restoration of fire-maintained (NDT4) ecosystems is a legal requirement under the Kootenay-Boundary Higher Level Plan order.
