The need for this study was identified following years of operational development and implementation of the treatment. Questions have been asked of the project sponsors regarding the ecological justification, and expected impact to long and short term timber supply. The licensees have already proven that short term timber supply has been increased due to the ability to operate in areas which were difficult to attain public support, heavily netted down, or completely excluded from the previous timber supply analysis. This net down occurred due to forest health factors such as the western hemlock looper event, visual sensitivity constraints, and wildlife habitat and other biodiversity needs. The forest estate modelling which was completed during the Tesera Scenario Planning Process of the Robson Valley EFMPP, further reinforced this gain in short term timber supply due to partial harvesting treatments, but also identified the need to better understand the medium and long term silvicultural feasibility of such harvesting. Further discussion in the winter of 2002/2003 resulted in the development of a preliminary, internal feasibility and opportunities report. This study forms part of the outcome of that report which showed that the treatment in question is unique to the province, in addition to such widespread application in the study area. The ability to analyze the main responses to the treatment will be afforded after sufficient growth has accumulated. As previously stated in the project design, this will be after about year 3 to 5 (fall of 2006 to 2008) when an initial analysis of diameter response, height response, natural recruitment and mortality will be completed. Ongoing re-measurements every 5 years will allow for development of trends, and even provide empirical input for growth and yield modelling. At this point we can confidently say that 28 long term sample plots have been successfully established within operationally innovative silviculture and harvesting areas of the Robson Valley and Dome Creek areas.
