An inter-agency working group on water soldier was formed in 2008 to help coordinate research, monitoring, control and prevention strategies. Agency groups include: Ontario Ministry of Natural Resources and Forestry, Ontario Federation of Anglers and Hunters, Ministry of the Environment, Conservation and Parks, Trent University, Lower Trent Conservation, and Parks Canada.

2019 Monitoring

July-August: Monitoring of Lake Seymour, Crowe Bay, Percy Reach and Glen Ross was conducted. A 50 m x 50 m grid was overlaid and at each point intercept, the presence/absence and abundance of water soldier was recorded. The results from the monitoring have revealed the 2018 herbicide treatment was a success. 2019 monitoring efforts revealed:

Lake Seymour: 38% reduction of water soldier (37.47 ha in 2018 to 23.33 ha in 2019)

Crowe Bay: 71% reduction of water soldier (3.86 ha in 2018 to 1.12 ha in 2019)

Percy Reach: 55% increase* of water soldier (38.63 ha in 2018 to 60.06 ha in 2019)

Glen Ross: 4% reduction (6.24 ha in 2018 to 5.97 ha in 2019)

*Note: Monitoring area in Percy Reach was also increased in 2019

August:  The Water Soldier Open House’s were held on August 28th and 29th at the Campbellford Community Resource Centre and the Trent Port Marina to inform the public of the monitoring and control efforts planned for the fall of 2019.

October:  As part of this project, the use of the herbicide Reward ® (active ingredient – diquat) is proposed to control the water soldier populations throughout the infestation area.
