In the Outdoors

So much of our appreciation of the natural beauty and outdoor opportunities available in BC relies on having a healthy environment where native species thrive. As an outdoor enthusiast, you can play a key role in protecting our province from invasive species by changing a few simple habits. 

We encourage you to take as many of the following steps as possible:

1. Learn to recognize the plants and other organisms you see in the outdoors. Invasive species tend to pop up in areas that we frequent – like dog walking trails and local parks, or along roadsides and in ditches. If you’re unsure about a creature or plant you don’t recognize you can:

  • Take a photo and e-mail us at
  • Call us at 1-888-933-3722 and we can link you with your local Invasive Species Committee
  • Use the provincial government’s Report-A-Weed service to report a suspected new sighting of an invasive plant species in BC.
  • Report ALL sightings of mussels (ie. zebra and quagga mussels) to the B.C. Conservation Officer Service (RAPP): 1-877-952-7277

2. Prevention:

  • On the land – Learn how specific invasive species can hitch a ride on gear, boots and firewood on our T.I.P.S. and Invasive Plants pages. Source firewood within a 50-mile radius of your campsite to keep invasive seeds out of your favourite natural areas. Learn more about easy steps you can take while camping, using trails, working in the field, or on your property through our Play Clean Go and Buy it Where you Burn it programs. 
  • On the waterClean-Drain-Dry – Clean off plant and animal parts and mud from your boat and equipment before entering or leaving a recreational area. Boaters should drain water from boat bilges, live wells and buckets and keep equipment clean and dry before travelling to help stop the spread of invasive aquatic wildlife that can damage recreational areas.

3. Take Action! Enhance our efforts by becoming an ISCBC member, joining your Regional Committee or making a donation to ISCBC

4. Resources: Take advantage of the wealth of information such as brochures, TIPS sheets, posters and other materials available in our Resources section. If we don’t have the information you need, try one of our partner organizations.

Thank you for being mindful about invasive species while enjoying BC's outdoors.
