Water Soldier Control

 

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, Ontario Ministry of Environment and Climate Change, Trent University, Lower Trent Conservation, United States Army Engineer Research and Development Center, Parks Canada and Ontario Invasive Plant Council.

September 2015, Pre Herbicide Treatment

July 2016, Post Herbicide Treatment

In October of 2016, the water soldier herbicide treatment was completed by SOLitude Lake Management (formerly Allied Biological). 117.87 hectares of water soldier were treated in Lake Seymour, 6.41 hectares were treated in Crowe Bay and 5.96 hectares were treated in Percy Reach over the two days. In early spring the Ontario Federation of Anglers and Hunters and the Ministry of Natural Resources and Forestry will be on the water performing the post treatment monitoring, assessing the success of the fall treatment. 

2016 Monitoring

May: The Water Soldier Surveillance Protocol was implemented to systematically catalogue the extent and distribution of water soldier in the Trent-Severn Waterway.

May-June: Reconnaissance was completed from below Lock 14 in Campbellford to lock 8, and the presence/absence and abundance of water soldier was recorded.

July-August: Monitoring of Percy Reach, Crowe Bay and Lake Seymour was conducted. A 50 meter by 50 meter grid was overlaid on the three water bodies and at each point intercept, the presence/absence and abundance of water soldier was recorded.  The following map was produced to illustrate the distribution of water soldier in the Trent-Severn Waterway.

July-August: Wildlife Habitat Canada awarded the Ontario federation of Anglers and Hunters with a grant that allowed the working group to test the efficacy of shade cloth enclosures on leading edge populations of water soldier. One population in Percy Reach and two populations in Crowe Bay were treated with shade cloth enclosures for two months. The 10 foot by 10 foot enclosures were fashioned with rebar, landscape fabric and zip ties to prevent sunlight from entering the covered water soldier plants. After the two months of being enclosed, all the water soldier plants under the enclosures were deceased.

September: The Water Soldier Annual Open House was held in Campbellford to inform the public of the monitoring results from 2016 and to inform about the proposed herbicide treatment for the fall, 51 members of the public came out to the information session.

October: Water soldier populations within the project area are being treated with the herbicide Reward (Diquat Dibromide) by Solitude Lake Management. Treatments tentatively start on the morning of October 18, 2016 in Percy Reach and Crowe Bay and will move onto Lake Seymour October 19 and 20.

Additional Partners

The Invasive Species Centre awarded a grant to the Ontario Federation of Anglers and Hunters in 2015 to be used for monitoring, surveillance, outreach and control.  National Fish and Wildlife Foundation has awarded a grant to the Ontario Federation of Anglers and Hunters to support the outreach, surveillance and control of invasive water soldier project in 2015. The Ministry of Natural Resources and Forestry has awarded the Ontario Federation of Anglers and Hunters with funding to control water soldier in the Trent- Severn Waterway.
