Abstract

Tree and site characteristics were compared between 19 groups of Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco (Pinaceae), infested by Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, and 19 uninfested groups to identify individual or combinations of characteristics associated with Douglas-fir beetle attacks. Of the tree characteristics, diameter, height, age, phloem thickness, bark thickness, and a standardized variable consisting of diameter divided by the last 10 years growth rate (DBHTYG) showed significant differences. None of the site characteristics showed significant differences between infested and uninfested areas. Two models, identified through discriminant analysis, placed 84 and 87% of the data in the correct infestation groups. These models included the variables diameter, height, phloem thickness, aspect, and DBHTYG in various combinations. The results were confirmed using a jackknifed cross-validation approach. These variables have potential for use in the development of a biological process model of tree and stand susceptibility to the Douglas-fir beetle.

Résumé

Les auteurs ont comparé les caractéristiques liées aux arbres et aux sites de 19 groupes de douglas, Pseudotsuga menziesii (Mirb.) Franco (Pinaceae), infestés par le dendroctone du douglas, Dendroctonus pseudotsugae Hopkins, à celles de 19 autres groupes de douglas non infestés en vue d’identifier les caractéristiques ou les ensembles de caractéristiques reflétant une prédisposition aux attaques par le ravageur. Parmi les caractéristiques liées aux arbres, des différences significatives ont été relevées dans le cas du diamètre, de la hauteur, de l’âge, de l’épaisseur du phloème, de l’épaisseur de l’écorce et d’une variable normalisée déterminée par le rapport du diamètre au rythme de croissance des dix dernières années (DBHTYG). Dans le cas des caractéristiques liées aux sites, aucune différence significative n’a été relevée entre les sites infestés et les sites non infestés. Deux modèles, établis par analyse discriminante, ont permis de ranger 84 et 87% des données dans les groupes d’infestation appropriés. Ces modèles intégraient les variables diamètre, hauteur, épaisseur du phloème, aspect et DBHTYG en diverses combinaisons. Les résultats ont été confirmés par validation croisée à l’aide de la méthode du jacknife. Ces variables pourraient orienter l’élaboration d’un modèle des processus biologiques influant sur la vulnérabilité des arbres et des peuplements au dendroctone du douglas.
