Perenial Pepperweed – Invasive Weed

“Invasive Weeds” are non-native plants that crowd our native and desirable species important to Warm Springs People and Wildlife.

Perennial Pepperweed forms infestations that can turn into monocultures.  Accumulations of its semi-woody stems degrade nesting habitat.  By displacing other species it threatens wildlife habitat and hay production.  It reproduces by seed and root fragments.  Hand pulling along with planting competitive vegetation reduces seed production.
