Non-Native Invasive (NNI) Species management is a growing
component of environmental mitigation projects. Stream corridors and
wetland sites are dynamic ecosystems subject to a wide range of
environmental influences from throughout the surrounding watersheds.
These ecologically volatile areas are exposed to the introduction of
NNI from anywhere in the upstream watershed.
a long term commitment to control of NNI, mitigation sites can be
quickly overwhelmed with a monoculture of undesirable plants.
Monocultures do little to promote the variety of habitat required by
wildlife, and they arenít as effective at protecting water quality
as a diverse plant community. EQR has long recognized that by
controlling NNI, we are protecting and promoting vegetative
diversity as a critical component of our healthy ecosystems.
Our control efforts cover a wide range of management techniques
including physical removal, cutting, and a range of herbicide
application measures. As each project is unique as to target plants,
place in the landscape, and required timing of treatments, control
efforts are selected that recognize those unique aspects. Non target
impacts are reduced through the use of hand removal in and around
desirable vegetation. In wetlands, when herbicide use is required,
only EPA Aquatic Use labeled herbicides are used.
EQRís Invasive Species Management Plans utilize an ecosystem
approach to invasive species management. The approach targets all
the weeds identified on a project, not only a primary species of
concern. With over 14 years experience in NNI control, EQR
understands that disturbed mitigation sites are extremely vulnerable
to the aggressive reproductive potential of invasive species.
A sampling of our NNI projects appears below.
