The herbicide treatments (of beach areas) are proposed to occur during the period of June 1, 2016 to May 31, 2019.
Pending further discussions with stakeholders and the outcome of current mechanical efforts, herbicide treatments may expand over time to include sites located in Sturgeon Banks and on the central east coast of Vancouver Island, including Comox, Courtenay, Deep Bay, Denman Island, Hornby Island and Sea Island.

Proposed local areas to be sprayed include all beach areas from Bowser to north of Comox, including all of Denman and Hornby Islands. Map showing areas affected:

This is for the eradication of invasive intertidal cordgrasses (Spartina anglica, S. patens, S. densiflora).
This application seeks approval to apply herbicide to invasive Spartina under a time limited federal Emergency Use Registration for the product Habitat (a.i. imazapyr), in combination with surfactant Ag-Surf II (a.i. alcohol ethoxylate).

This cordgrass was introduced to the estuaries of Oregon with shipments of oysters and has been seen dominating and crowding out native vegetation there.[ Likely shipments of oysters to this area have also caused contamination of beaches with cordgrasses.
