Monitoring
Trent-Severn Waterway
Each year from June – August, sections of the Trent-Severn Waterway are monitored for the aquatic invasive plant, water soldier. Teams from the Ontario Federation of Anglers and Hunters, Parks Canada, and the Ministry of Natural Resources systematically monitor using a 50m x 50m point intercept, recording the presence/absence and abundance of water soldier. The results from monitoring help inform treatment success and needs.
