For three weeks in the summer of 2016, Calgary Parks used goats to control weeds in a portion of West Nose Creek/Confluence Park. Approximately 100 goats ate invasive weeds, including Canada thistle, and in doing this, helped encourage biodiversity, the growth of native vegetation and enhanced the health of this natural area. This pilot is part of an integrated approach to managing invasive species.
The goats were monitored and managed 24 hours a day by a professional shepherd, herding dogs and horses.
The focus of this pilot was to determine if goat grazing is a viable land management tool for managing invasive weed species in City parks, and it is important that Calgary Parks comply with The City of Calgary Land Use Bylaw and The Responsible Pet Ownership Bylaw. We were able to use goats in this pilot because of a specific land use designation that permits livestock grazing in this park.

Why we used targeted grazing
Targeted grazing has proven to be an effective land management tool in other municipalities. It is cost effective, and offers numerous benefits, including:
- an environmentally friendly and effective method to manage invasive plant species; and
- a feasible solution for controlling weeds near water bodies and on slopes.
Now that the pilot is complete, we will be conducting an assessment and performing a data evaluation to determine project’s effectiveness. If successful, the initiative may be expanded to other natural areas in the city.
