Get on Top of Invasives Early

The Boundary is flush with spring growth. Wildflowers are coming out in force among the grasses, shrubs, and trees. Arrowleaf balsamroot is blooming in the local grasslands and is easily sighted along Highway 3. Saskatoons and wild strawberries are also putting out blossoms, readying for summer fruits. Unfortunately, our beautiful native species are not the only plants taking advantage of the sunshine and rain. Invasive plants are also well into their spring growth. Now is a great time for property owners to identify any unwelcome species and make a management plan.

There are a few priority species for which Boundary residents should be watchful. If left to their own devices these invaders will outcompete native species which can lead to a loss of biodiversity and degraded land quality. In addition, some of these plants are toxic and pose a danger to people, pets, livestock, and wildlife.

Leafy spurge is one of the plants included in the RDKB New Invaders Program which covers treatment costs up to 5 acres or $500 on private land. Leafy spurge is toxic to livestock and can cause severe skin irritation and even blindness in the case of external contact. Hoary cress is another new invader which competes fiercely with native plants and can take over pastures and hay fields, forming monocultures in some areas. Identifying invasive species early on and acting swiftly to eradicate or control their populations is important to protecting our local ecosystems. A few plants can turn into a big problem in a matter of a year or two.
