AQUATIC INVASIVE SPECIES REMOVAL


Since 2011, Aquatic Plant Management (APM) has been working with Lake Associations and Lake Districts across the Midwest to prevent proliferation of Eurasian Watermilfoil (EWM), Curly Leaf Pondweed (CLP), and various other aquatic invasive species. Using various eradication methods, APM has the knowledge and experience to operate under a variety of subsurface conditions and EWM/CLP densities.

APM has documented success working with riparian owners to clean their lakes of invasive species. Our most successful approach involves identifying and eradicating pioneering colonies. It is imperative that these new colonies are quickly removed before the invasive plant has a chance to develop other colonies that ultimately, upon reproduction, will infest a new part of the lake. Our specialty is a natural non-chemical manual extraction of aquatic invasive plants without the potential negative effects that other options may introduce.

HAND HARVESTING

Our internally developed strategies for hand-pulling are highly effective at minimizing re-growth of EWM. One of the most important techniques is minimizing the diver’s disturbance of the plants and sediment underwater. We do this by moving carefully and deliberately, keeping our fins and snorkels away from the plants and bottom. Skilled and experienced divers are paramount to minimizing fragmentation. To further prevent the negative effects of fragmentation we use a pool net to collect any leftover fragments.

DIVER-ASSISTED SUCTION HARVESTING (DASH)

Diver-Assisted Suction Harvesting, or DASH, provides an efficient and effective method of aquatic invasive plant removal. DASH has been proven successful in its ability to remove large, high-density beds of EWM from a variety of lake bottom conditions in a relatively short amount of time. Surface-supplied air allows our divers to remain underwater for an indefinite amount of time, greatly improving efficiency and allowing for a more systematical approach to colony removal. Once underwater, a team of two divers removes the roots of the plants and feeds them into a 50-foot suction hose. The entire plant is then transported via suction hose to the deck of the boat, at which point they are pumped directly into large mesh bags for collection. Due to the nature of DASH, the risk of plant fragmentation during transport to the boat is nearly eliminated.

 

 

RESIDENTIAL SERVICES


Aquatic Plant Management LLC also provides residential hand-harvesting services to homeowners, property managers, and summer camps around the Northwoods of Wisconsin. Our services allow you to reclaim your shoreline, providing you with a weed-free swimming area, ready to be enjoyed by friends and family.

SUBMERGED AQUATIC PLANT REMOVAL

  • Removal of native nuisance and invasive plants
  • Complete root removal, critical in preventing regrowth

FLOATING AQUATIC PLANT REMOVAL

  • Removal of floating weed mats and floating fragments of submerged plants
  • Especially helpful in areas with high boat traffic, in bays, or around channels

DANGEROUS OBJECT REMOVAL

  • Removal of dangerous objects located in or around swimming areas
  • Examples include broken glass, sharp rocks/sticks, cans, bottles, or any other debris considered a risk to swimmers

DIVER-ASSISTED SUCTION HARVESTING

  • Depending on the target species, some people may qualify for diver-assisted suction harvesting
  • Produces dramatic, lasting results in a short amount of time
