Modélisation de la remontée de la cime du pin gris

by Power, Hugues

Abstract (Summary)
Jack pine crown recession was studied using data from stands varying in age, density and site index. The resulting model should be included in the CROBAS forest growth model. As a first step, several crown height equations were derived from previously published results and from a stepwise selection. These equations were then derived with respect to age to estimate crown recession rates. Predicted crown recession rates were then compared to a data set of crown recession values calculated from dated branch mortality. The proposed method of using the time was able to explain a significant amount of the observed crown recession rate. Height growth and stand competition seem to be the main factors that influence crown recession rate.
