Baldcypress (Taxodium distichum) and pondcypress (Taxodium distichum var. imbricarium) are two species commonly found in forested wetland ecosystems of the southeastern United States. Both species can improve water quality, provide wildlife habitat, mitigate flood waters, and help control erosion, making them ecologically important trees. However, baldcypress and pondcypress are both hosts for the baldcypress leafroller (Archips goyerana), a native defoliating pest first documented in southeastern Louisiana in 1983. Baldcypress leaf roller defoliation events can cause reduced tree growth, crown dieback, and, in some cases, host tree mortality. But what do we know about this pest and how do we reduce its impact?
