Invasive Species

For over 25 years EQR has been controlling non-native invasive plant species in forests, right-of-way, and aquatic settings.  We are currently licensed in Maryland, Virginia and the District of Columbia.   We utilize the best management practices for each species which includes mechanical and chemical control methods.  We are knowledgeable of native and non-native plant species and practice extreme care with the use of herbicides, paying attention to temporal and spatial growth patterns, seasonal control efficacies, as well as microclimate weather, wind and wet locations.  


We comply with the laws of each locale and submit toxic materials permits and critical areas permit when required.  Managing the non-native invasive species when restoring a wetland or stream is crucial to a long-term maintenance program and vital to successful native plant establishment.
