Plain Language Summary
In late July of 2016, strong winds swept trillions of spruce budworm moths from their outbreak range in eastern Quebec through the Atlantic region. There were so many moths that the event was detected by Environment Canada’s weather radar. The citizen science program Budworm Tracker was introduced in 2015 to help scientists better understand how these mass dispersal events might impact the rise and spread of budworm outbreaks. Although most of the moths in 2016 ended up in northeastern New Brunswick, citizen scientists determined that the dispersal of spruce budworm moths probably ranged as far as Cape Breton, Nova Scotia, and Maine, USA. Understanding how spruce budworm populations spread during outbreaks is a key component in developing the early intervention strategy being used to contain budworm spread in Atlantic Canada.
