The goals of this study were to: 1) to assess the damage of shot hole borer infestation on vegetation at the San Diego River, 2) to provide baseline post-infestation data on habitat composition and structure at the San Diego River; 3) to determine whether trees in wet areas were more vulnerable to infestation than in dry areas; and 4) to determine whether trees in nutrient-enriched areas were more vulnerable than in unenriched areas. We used these data to assess the effects of shot hole borer infestation on population size and distribution of the endangered Least Bell’s Vireo (Vireo belli pusillus). These data were meant to inform natural resource managers about the status of the infestation and potential effects on Least Bell’s Vireo at the San Diego River and guide management practices as appropriate to reduce the effect of the infestation on this endangered species.
