The article discusses a study on the rapid removal of symptomatic trees in Manitoba and its impact on Dutch elm disease (DED) infection rates. Selected areas were coupled on the basis of geographic proximity, population size, and area under DED management. To select a treed urban region within each community as a study area, aerial imagery was used. The rate of compliance with the target time of removal of infected trees was found to be quite high in all communities from 2004 to 2009.
