GBF 2021 - Phragmites Report

22 Ontario Parks GBF has collaborated with Massassauga Provincial Park and Friends of Massassauga Provincial Park for the past 4 years. This yead, control withn the park was wholly managed by the park as stands were so diminished. Massassauga has 26 stands of Phragmites within the boundary. This park is heavily used by canoeist, kayakers, and campers that are not always aware of the damage caused by invasive species. GBF has heard reports of spread due to portage routes which is why it is important to stay with the mapping and control in this high used area. Due to control efforts over the past few years and high water levels in 2020, 22 stands are now in the monitor/ eradicated stage and 4 sites were controlled. The 4 sites which received control include Port Rawson (near site 215), Miron Island (near Halo Island), Conger Lake, and a new stand in Lough Bay. Pointe au Baril Marine Patrol GBF has helped train the Marine Patrol over the years – but now they have taken complete control over management. Here is an extract from the Pointe au Baril Islanders Association Marine Patrol Report 2019, written by Tom Wunderlich and Chris Lusty, supervised by Bill Culp and Emma Berton. This summer the Marine Patrol monitored a total of 13 Phragmites stands around the Pointe au Baril area. Before the end of July, the cottagers with Phragmites were emailed about the optimal cutting dates for this summer and to ask if they needed assistance or training. This year the cutting dates were from August 6 th to 20 th . A separate email was sent to cottagers whose stands did not grow this year, they were directed to thoroughly check their site, and monitor it for the next few years. Due to COVID-19 GBF recommended that no large group cuts be attempted to keep people social distanced. Luckily, there were no stands in this area large enough to necessitate a big group. The stands at Bonnie Island (Sturgeon Bay), Mud Channel, and the Berton’s (A316) did not grow back this year suggesting that the removal efforts have been successful. Monitoring of these sites should continue in the future to ensure Phragmites does not come back. There was also a stand at Cradle Island in Shawanaga Bay where a past stand had been cut. Unfortunately, there were no coordinates, and the Patrollers were unable to find the stand, this suggesting that it too has been eradicated. The stands at Chicken Channel, Frederick’s Inlet, and Cambria Island had very little Phragmites and took less than half an hour to cut. These sites are close to eradication and may not grow back next year. A stand at Desmasdons and in Upper Shawanaga, were cut taking one hour or less. These stands likely need another year or two of cutting before they are eradicated. Four new sites were found this year, two of which are suspected to be native. These sites in Upper Shawanaga, and White Island/Wawonaissa will need to be checked by a member of the GBF to confirm their native status. The two new invasive stands were found by the Hot Dog Stands south of E19, and on a path at the Ojibway Club. The stand by the hot dog Stands was cut by the patrollers, Doug Muir, head of Ojibway maintenance sprayed herbicide on the second stand.
