GBF 2019 Phrag Report

9 Township of Georg i an Bay (Honey Harbour, Present Island, Quarry Island, Wolverine Beach to Macey’s Bay, Severn Sound to Port Severn, Georgian Bay National Islands Park, Lily Pond, Cognashene, Wah Wah Taysee, Twelve Mile Bay) The program results are strong: In 2019, 38% of the invasive Phragmites sites on the shorelines of Georgian Bay Township (GBT) received management. Specifically, of the 359 sites that GBF mapped on 480 km of shoreline, 112 sites were cut; removing 12,179kg of biomass, and noting 26 sites were eradicated (this is in addition to the 36 sites that were eradicated prior to 2019). To achieve this, resources included hosting eight community cuts and reaching out to 200+ community members. GBF’s team consisted of a supervisor and three local post-secondary students dedicated to the Township of Georgian Bay, specifically in Honey Harbour and Cognashene, and were joined by two other GBF students as needed. GBF staff continued to build relationships with local homeowners and businesses in the community. At this point, GBF notes that the majority of these stands are manageable (79% or 282 stands are under 10 m 2 ) verses areas like Tay, where we are seeing many stands well over 40m 2 . This is a risk for GBT if the stands are left unaddressed in areas like Honey Harbour; and it will be much more costly and time-consuming to manage. To date in GBT, there are 112 stands that while reduced will likely need to be cut again, and 221 that have received no treatment. Sites take about 2 to 5 years to eradicate depending on their size and density. All 359 stands have been analyzed and a 5-year management plan has been developed. We have seen success in Honey Harbour and Cognashene, but we need to expand our capacity to more community control in Honey Harbour and extend more control measures down to the Severn
