Numerous non-native species infest our wetlands, green spaces, gardens, and back alleys. Many of them are considered invasive. Because they can be extremely harmful to natural, agricultural, and urban environments, Provincial laws require these species be prevented, eradicated, or controlled. 

There will be a workshop at Police Point Park Nature Centre Saturday, May 4, from 11 a.m. – 4 p.m. Compounding the problem is most people now consider them a normal part of our nature reality. 

Left unchecked urban infestations can act as reservoirs delivering a continual invasion to native grasslands and cultivated areas where this problem is already rampant. 

These intruders must be stopped - working together we can accomplish this objective. To meet our goal, the Interpretive Program and Grasslands Naturalists will cohost this workshop focusing on these problem plants and animals. We encourage gardeners, landowners, renters, and anyone who loves nature to attend. Attendees can discover how to recognize these species and get rid of them, and learn about attractive alternatives to use. We hope the workshop will bring together a knowledgeable and empowered group ready to report invasive species whereabouts, help remove them, and assist neighbors who need aid. 

The workshop will have two sessions. The early session will feature short presentations from experts combating these species locally and provincially. The late session will have learning tables staffed by numerous groups to discuss a variety of relevant topics. 

The event is free but please register at by May 1 so we can determine food and space needs. Lunch will be provided to those attending the full workshop. 

A big thank-you goes out to the Medicine Hat & District Horticultural Society, the South East Alberta Watershed Alliance, Blondie’s Gift & Garden Centre, Windmill Garden Centre & Butterfly House, Animal World, and Rod Wilson with Royal LePage Community Realty for providing funds for this event.
