Noxious Weed Control

Noxious weeds are some of the greatest threats to native ecosystems. Plants like knotweed (Polygonum spp.), old man’s beard (Clematis vitalba), and Robert geranium (Geranium robertianum) harm natives by shading out the growth of young plants. Others like tansy ragwort (Senecio jacobaea), poison hemlock (Conium maculatum), knapweed (Centaurea spp.), and giant hogweed (Heracleum mantegazzianum) can actually pose threats to humans and livestock due to high levels of toxins.

Our team of ecologists have spent years battling these troublesome invaders and utilize a wide and holistic array of tools known as integrated pest management or IPM.

Integrated pest management, contrary to popular belief, does not consist solely of spraying herbicide. We use manual control to physically remove undesirable plants, cultural control, biological control using natural pest enemies, and chemical control for those toughest weeds.
