Modélisation de la remontée de la cime du pin gris
|Abstract:||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.|
