Invasive Phragmites

Since 2021, FOCA has been supporting our member Associations with funding and technical support for projects that fulfill the goals of the Green Shovels Collaborative.

On-the-ground projects undertaken by FOCA member Associations have included management, removal, and control plans for invasive Phragmites, as well as educational and awareness programming. 

Invasive Phragmites has been called Canada’s WORST invasive species. Management and eradication of invasive Phragmites has become an increasing cost for municipalities across Ontario.

Phragmites is a very tall and fast-growing perennial grass now covering nearly 17,000 hectares of shoreline, wetlands and roadsides. It creates ecological dead-zones and impacts at-risk species.

June 25, 2024 – FOCA’s partners at the Invasive Species Centre (ISC) have announced the 2024 Phragmites DNA Screening Program is back, to help site managers determine if the plant they have is native or invasive Phragmites, or a hybrid. Applications are particularly encouraged from areas in central and northern Ontario where native Phragmites is more frequently observed, and from newer site managers in other regions. Learn more from ISC here.

In related news, ISC encourages everyone to refer initially to the visual identification traits explained in the journal article of McTavish et al (source of the image at the side): June 2023 – Best morphological [outwardly visible] traits for rapid and simple separation of natural and introduced common reed (Phragmites australis) are described as follows; consult the article link for more information:

  1. % of leaf sheaths retained on old dead standing stems (if more than 50% still attached, likely invasive; if less than 30%, likely native)
  2. ligule height: remove a leaf from the middle of the plant and measure the basal tissue – a darkened membranous band where the leaf meets the stem; exclude any light-coloured hairy fringe at the top of the band (refer to images in the journal article, Figure 3): if greater than 0.35mm, the native species is indicated
  3. stem colour (dark red pigmentation indicates native stems)
  4. fungal stem spots indicate the native variety (but not all native plants display these spots, so the absence of spots is not conclusive)
  5. glume length (from ligule to tip of leaf) and leaf length comparisons, with the native variety tending to have a longer lower glume and/or shorter leaf length (see article, Figure 3 for details)

May 28, 2024 – Ontario scientists are using caterpillars to combat an invasive aquatic plant (CBC News – Hamilton) – Since 2021, Jones’s team has released over 21,000 caterpillars and larvae at around 30 locations across Ontario such as this. The Canadian Food Inspection Agency approved two moth species, Lenisa geminipuncta and Archanara neurica, for use as biocontrol in 2019. The caterpillars only eat phragmites, Jones said, and as they grow, they’ll “hopefully” munch through three or four stems and “do a fair amount of damage to the phragmites.” The scientist is working with Ducks Unlimited Canada, the federal department of Agriculture and Agri-Food Canada, the University of Toronto, and the Centre for Agriculture and Bioscience International in Switzerland.

May 2, 2024 – new round of program funding for 2024 projects: associations are encouraged to apply by May 30th for funding from the Green Shovels Collaborative for projects to take place this year, to help map and manage invasive Phragmites. There is an emphasis this year on collaborative plans – so applying together with adjoining lakes or regionally may increase your chances.

March 2024 – review the posted video recordings of the Ontario Invasive Plan Council‘s virtual event with experts in the field providing information on invasive Phragmites management:

View an earlier FOCA webinar: Invasive Phragmites (June 2021). Join FOCA and Brooke Harrison of Georgian Bay Forever, discussing invasive Phragmites: its characteristics, its spread, and its controls. (Online, 1 hour)

During the webinar, attendees asked how to report areas of invasive Phragmites spotted along highways. The answer is to contact the Ontario Ministry of Transportation online, or call 416-235-4686 (Toll Free 1-800-268-4686).

Following successful projects by FOCA member Associations undertaken in 2022 with Green Shovels Collaborative  funding (learn more about the Collaborative below), FOCA was pleased to announce that we have funded a new round of  2023 proposals from our member Associations for on-the-ground projects focused on invasive Phragmites management, starting this summer and to be completed by February 2024.

Tackling the problem of invasive Phragmites (European Common Reed):

FOCA is part of the Green Shovels Collaborative of conservation organizations that have a shared interest in protecting nature and the economy. The Green Shovels Collaborative includes:
  • Federation of Ontario Cottagers’ Associations
  • Nature Conservancy of Canada
  • Ontario Federation of Anglers and Hunters
  • Invasive Species Centre
  • Ducks Unlimited Canada
  • Ontario Invasive Plant Council.

With funding support from the Ministry of Natural Resources and Forestry, one goal of the Green Shovels Collaborative was to prepare a Strategic Framework for Phragmites Management in Ontario. The document was released in late 2021 in draft format, for public feedback:
