Urban Forestry will continue with management of Dog Strangling Vine in High Park over the next 3-4 weeks this summer. Staff have been strategically and actively managing a small number of areas of vegetation within High Park for over 20 years. The majority of these efforts are focused on Woodland and Savannah sites that have rare species and high-quality understories that are at risk of being outcompeted by a number of invasive species.
Dog Strangling Vine management is undertaken by trained Urban Forestry staff using a variety of methods, including hand digging of individual plants and herbicide application to individual stems as part of integrated pest management. Dog strangling vine management is performed over the summer months in preparation for the annual spring burn and spring/fall plantings, aiming to increase biodiversity and enhance ecological function. Additionally, these invasive species management efforts aim to minimize damage to the ecosystem caused by various invasive species, not to eradicate these species.
Herbicide warning signs will be posted 24 hours prior to herbicide treatment and signs will be removed 48 hours after treatment. If people see the signage they should remain on trails. The signs have additional information about the invasive species being managed and a phone number for any public enquiries.
