Leader Damage in White Spruce Site Trees in Northeastern British Columbia Nigh, G.D.

Abstract: Anecdotal information suggests that damage in leaders of white spruce [Picea glauca (Moench) Voss] is less in the Boreal White and Black Spruce (BWBS) biogeoclimatic zone than was found in a previous study in the Interior Cedar- Hemlock (ICH) and Sub-Boreal Spruce (SBS) zones. The purpose of this project was to confirm or refute this assertion. Forty-six 0.01-ha stem analysis plots were established in managed stands in the BWBS zone and data from those plots were combined with data collected previously from the ICH and SBS zones. The stem of one sample tree per plot was split, and the heights of the nodes demarcating the ends of the annual height growth were measured. Leader damage was noted. The height growth model that was fit to the ICH/ SBS data was based on the combined data set. Indicator variables allowed the parameter estimates of the model to vary across the two projects. The analysis indicated that the effect of damage on height growth was the same for both the ICH/SBS and BWBS data, but the growth parameters were different. There were fewer incidents of damage in the BWBS data than in the ICH/SBS data. This should result in less biased site indices in the BWBS zone than in the ICH and SBS zones.
