- Abstract
The article presents a study which examines the relationship between tree abundance and patterns of mortality in three size classes during the recent extended drought in southwest Colorado, northern New Mexico and northern Arizona. The influence of tree density and basal area on bark beetle infestations and direct drought impacts is examined using logistic regression models. According to the study, the severity of the regional drought has masked density-dependent patterns visible in less severe drought conditions.
