Invasive Species Awareness Week – Protecting Our Lands from Harmful Weeds

Invasive Species Awareness Week is here! This annual initiative highlights the importance of recognizing and managing invasive species to protect our ecosystems, agriculture, and local landscapes. In the County of Newell, invasive weeds pose a significant threat to native plant life, pasturelands, and waterways.

What Are Invasive Weeds?

Invasive weeds are non-native plants that spread aggressively, outcompeting local vegetation and reducing biodiversity. They can also be harmful to livestock, increase fire risks, and interfere with crop production. Once established, these species are difficult and costly to control.

Troublesome Weeds in Our Region

Here in the County of Newell, some of the most problematic invasive weeds include:

• Burdock – Known for its large leaves and burr-like seed heads, burdock can choke out native plants and become a nuisance to livestock.
• Purple Loosestrife – A water-loving plant that invades wetlands, reducing habitat for fish and birds.
• Yellow Toadflax – A deceptively pretty but aggressive spreader that takes over pastures and roadsides.
• Baby’s Breath – Commonly seen in floral arrangements, this plant spreads rapidly in dry soils and competes with native grasses.
• Knapweeds – A variety of knapweeds plague our area, harming rangelands and reducing forage quality.
• Milkweed – While beneficial for monarch butterflies, milkweed can be toxic to livestock if consumed in large quantities.
• Foxtail – This grass is hazardous to pets and livestock, as its barbed seeds can cause serious injuries.
• Kochia – A highly drought-resistant weed that spreads quickly, often forming dense stands in fields and ditches.
• Canadian Thistle – A deep-rooted weed that spreads aggressively through both seeds and underground roots.
• Tall Buttercup – Toxic to cattle and difficult to control once it takes hold.
• Scentless Chamomile – This daisy-like plant can quickly overrun disturbed soils, reducing crop yields.
• Downy Brome (Cheatgrass) – A highly invasive grass that dries out early in the season, creating a major fire hazard and competing with native grasses for resources.

What Can You Do?

• Learn to Identify – Recognizing invasive weeds is the first step in preventing their spread. If you spot them on your property, act quickly.
• Report Infestations – If you see a large outbreak, report it to the County so we can provide guidance and control measures.
• Use Prevention Strategies – Clean your equipment, vehicles, and boots when moving between locations to prevent seed spread. Avoid planting non-native species in gardens.
• Take Action – Regular mowing, hand-pulling, and appropriate herbicide applications can help keep invasive weeds in check.

By staying informed and proactive, we can work together to protect our lands from the harmful impact of invasive species. Let’s do our part to keep the County of Newell beautiful and sustainable for future generations!
