Research Objective

Project Description

To establish the Prairie Weed Monitoring Network (PWMN), network of federal researchers, provincial specialists, and academics guiding weed biovigilance for the prairie region; to complete the seventh set of weed abundance surveys in the prairie provinces since this series of provincial surveys began in the mid-1970s; to complete the fifth set of pre-harvest herbicide-resistant weed surveys in the prairie provinces since this series of provincial resistance surveys began in the early-2000s; to complete the third set of post-harvest herbicide-resistant kochia and Russian thistle surveys in the prairie provinces since this set of provincial surveys began in the early-2010s; to complete a spatial risk assessment for the evolution of herbicide-resistant weeds in prairie cropping systems by integrating data from weed surveys, species-specific biology, cropping systems, and herbicide sales/use; to develop tools to forecast weed community behavior and range shifts in response to management factors and climate change.
