Dog-strangling vine is an invasive perennial herbaceous plant in the milkweed family (Asclepiadaceae). It is spreading rapidly and causing damage to ecosystems in southern Ontario. Dog-strangling vine invasions can harm biodiversity and the economy in a number of ways. It forms thick mats of vegetation which hinder recreational activities, choke out native species, and negatively impact managed woodlots.
