Invasive Species

Invasive aquatic weeds are advancing throughout the United States. Each year we lose more habitat to the effects of these noxious weeds. Plants like Eurasian Milfoil, Curly Leaf Pondweed, Hydrilla, Water Hyacinth, Flowering Rush and Purple Loosestrife rapidly replace native species in littoral areas of our lakes. They form dense monocultures that impact water quality and habitat as well as posing a threat to other water uses. Federal, state and local agencies are charged with restoring these habitats, but they often do not have the expertise in-house to manage these resources.

AquaTechnex is an expert in the control of these harmful introduced species and in the restoration of the aquatic habitat they impact. The firm is regularly called upon by agencies nationwide to help craft solutions. These solutions start with accurate mapping and assessment of the water body. We then develop a treatment program that will selectively target the invasive plant and allow for the recovery of native aquatic plants.

In addition to operational control efforts, our team is regularly selected by federal and state research organizations to support them in the development of new technologies. Many of these technologies are then implemented as part of our operational programs. Examples include dye studies to simulate herbicide applications to document contact exposure time, using barrier curtains to isolate treatment areas and using aquatic plant assays to optimize herbicide applications.

With over 40 years of experience in this field, we have the talent and tools to get the job done.
