SUMMARY:Forest Pest Damage from the Carbon Sequestration Perspective
DESCRIPTION:Both native and non-native forest insects and diseases across the contiguous United States are reducing the ability of the nation’s forests to capture and store carbon dioxide. This webinar will describe a study published in Fall 2021 in Frontiers in Forests and Global Change that calculated forests damaged by insects sequestered 69% less carbon than undamaged forests\, while those affected by disease sequestered 28% less carbon. The webinar will briefly cover the overarching findings of the study\, and then go into depth on what it means from the invasive forest pest perspective- including how to bring this issue to light when discussing prevention and management of forest pests\, and what improvements to current actions could further mitigate these sequestration losses.

SUMMARY:Breeding for EAB-Resistance: What Does the Future Look like for Ash?
DESCRIPTION:EAB threatens the survival of ash trees in the U.S. where it is a common hardwood species especially in riparian and wetland forests. Ash was also used extensively for soil conservation (including wind breaks) and in urban green spaces and streets. Surviving\, or “lingering”\, ash trees that had maintained healthy canopies for at least two years after all other large ash trees had died were identified in natural forests long-infested by EAB. EAB egg bioassay experiments confirmed that these trees have an increased level of resistance due to defense responses\, including death of early instar larvae\, larvae with significantly lower weights\, or leaves less preferred for feeding by EAB adults. This webinar discusses research now being done to further understand this phenomenon and other findings to develop tree-improvement programs that could be successful in producing EAB resistant seed. Longer term goals include combining the best performing progeny from many families into a second generation seed orchard\, so that the seed produced may be used for restoration plantings.
