Weed Control Research

Ecological Control of Invasives

An integral part of ecological restoration projects is the removal and long-term control of invasive plants and weeds.  We conduct research into techniques that lower the overall cost of invasive plant control while meeting the effectiveness requirements of a healthy landscape. By paying close attention to how invasive weeds establish themselves, especially with regard to the timing of seed production, we can effectively combat invasive species without excessive expense.

Multiple invasive plant control techniques are being evaluated, including:

  • using native plants to out-compete invasive weeds
  • controlling the production and dispersal of invasive plant seed
  • non-manufactured chemical controls
  • improved methods of manual control
  • optimal timing of control regimes, including pre-emergent treatments

Top 5 Invasive Weed Species Research Priorities

  1. Ficaria verna (lesser celandine) 
  2. Microstegium vimineum (Japanese siltgrass)
  3. Rosa multiflora (multiflora rose)
  4. Phragmites australis (common reed)
  5. Alliaria petiolata (garlic mustard)
