Noxious weeds are aggressive invaders that harm native plant communities, reduce agricultural productivity, degrade wildlife habitat and can carry harmful insects or diseases. In partnership with the Grand County Division of Natural Resources and the Middle Park Conservation District, the Town of Grand Lake can help residents and business owners identify and manage these invasive plants effectively. Weed management is not a one-time task--effective control requires persistent effort over several years. Working together, we can protect our ecosystem and preserve the beauty of Grand Lake.

The four most common noxious weeds found in Grand Lake:

• Scentless & Mayweed Chamomile,
• Oxeye Daisy
• Canada, Musk, & Bull Thistle
• Common Mullein 

After removing noxious weeds, revegetating with native or adapted plants is one of the best defenses against re-infestation. Native grasses, wildflowers, and shrubs are beautiful, low-maintenance once established, and support pollinators and wildlife. You can find a full list of plants well-adapted to our montane environment (mountains above 7,500’ of elevation) on the Colorado Native Plant Society website.
