Common Tansy (Tanacetum vulgare), also known as Bitter Buttons, Cow Bitter, Mugwort, or Golden Buttons growing in the East Kootenays of British Columbia. Native to Europe, it was first introduced to North America as a medicinal herb. Amongst many other uses, it has traditionally been used as an insect repellent. Growing in North America, it forms dense patches and outcompetes native plants.

Lacking natural predators and diseases, invasive plant species grow and spread rapidly throughout native ecosystems. Once established, invasive plants are very difficult to control and they choke out native species. This greatly affects wildlife habitat and rangeland. On a global scale, invasive pant and animal species are considered to be the second largest contributor to the loss of biodiversity, next to the loss of habitat.
