DFTM Early Warning System
Pheromone Trap Data
A network of Douglas-fir tussock moth pheromone traps is in place throughout the western US. These traps are monitored annually with the expectation that the number of moths caught in the traps will increase for several years prior to the onset of visible defoliation, thus giving land managers an early warning. Learn more about this Early Warning System, or view an overview of DFTM in the Pacfic Northwest.
