Electronic Field Guide » Invasive Plant Management » General Recommendations

Prepared by Emily Rauschert (Plant Science)

  • A pre-construction inventory of the areas that will be disturbed should be performed to assess which invasive plants are already present, how to best manage them, and what control will likely be necessary. Plants that reproduce from rhizome/root segments should receive a high priority for treatment before disturbance to limit their spread.
  • Because disturbance is a critical factor in most invasions, care should be taken to minimize disturbance and to use existing disturbed areas when possible.
  • All equipment should be cleaned before moving into new uninvaded or sensitive areas.
  • Certified weed-free seed, soil, gravel, and mulch should be used to avoid the introduction and establishment of new problem species.
  • Disturbed areas should be surveyed annually at the appropriate time of year to detect early infestations. This monitoring should continue for 5 years after work ends or after the last individual invasive plant is seen.
  • Appropriate management of the invasive plant populations depends on which species are present. Different species require action at different times of the year, with different chemical or mechanical methods.
