Heavy duty aquatic plant harvesters are highly efficient in the management of free-floating, submerged or emergent aquatic vegetation. It offers an environmentally sound solution for the control of nuisance vegetation and excessive aquatic plant growth in all types of waterways.
An aquatic weed harvester works like an underwater lawnmower to cut and collect vegetation to be stored on board the vessel. A conveyor fitted at the front end of the machine can be submerged up to six feet below the water level. One horizontal and two vertical cutting bars are used to cut the vegetation as the machine moves through the water. When the harvester is fully loaded it returns to shore for unloading.
Mechanical aquatic weed harvesters come in a variety of different models available at stock sizes to match the size and scope of a project. A fully customized weed harvester can also be designed to meet exact needs, depending on the type of vegetation, the size of the waterway, the percentage of weeds that need to be removed, and how quickly they need to be harvested.
Mechanical Aquatic Weed Harvesting
Mechanical harvesting is an environmentally friendly and effective management strategy for the removal of nuisance aquatic plants. Aquatic harvesting enables plant-choked waterways to be cleared or channels to be cut through dense areas of vegetation to increase water flow or enhance the recreational use of water bodies.
Harvesting is also a viable option for dealing with algae issues. The removal of large filamentous blooms of algae provides relief for existing algae issues by removing the biomass and thereby reducing the overall nutrient load. Clearing dense vegetation reduces unwanted nutrients such as nitrogen and phosphorous from water bodies and is an essential component of any long-term water restoration plans.
Employing a committed harvesting program to significantly reduce the density and cover of annual aquatic plants will remove generations of seeds from the growing cycle which is highly beneficial in the control of unwanted aquatic vegetation.
Area-selective aquatic harvesting can be employed for the management of habitat structures such as fisheries and other wildlife habitats without drastically altering the vegetation assemblage of waterbodies.
What Happens to Plants after Aquatic Weed Harvesting?
Horizontal and vertical sickle-bar cutters are used to shear plant vegetation and collect it to be conveyed on-board to shore. Harvesting projects can sometimes yield up to 15 tons of vegetation biomass per acre, which is a lot of vegetation to dispose of. That is why it is important to identify and use suitable off-loading sites close to the project site with the appropriate equipment to handle these high plant volumes and keep the process moving. A variety of special equipment such as shore-based conveyer systems and high-speed transport barges are available to facilitate the efficient disposal of aquatic plant material.
The Advantages of Mechanical Aquatic Weed Harvesting
– An alternative option for situations where herbicides are inappropriate or not desired.
– An eco-friendly solution without creating temporary water use restrictions during or after the harvesting process.
– Provides a solution for area selective control of nuisance aquatic species.
– When combined with other control strategies, it enhances the effectiveness of vegetation control
– Effectively removes nutrients and biomass from a waterbodies
– Provides a long-term solution for the removal of certain species
What Types of Aquatic Plants Can Most Effectively Be Removed by Mechanical Harvesting
Although mechanical harvesting can be used to remove a wide variety of different invasive vegetation, it is most effective at removing certain plants like water chestnuts or water hyacinths that form a dense canopy on the surface of water bodies. One or two harvests are typically recommended for season-long control of nuisance aquatic species.
Professional lake and pond management services can help improve water quality and preserve our natural resources, thereby reducing our environmental footprint. Services typically include lake and pond management, aquatic and algae control, fisheries management programs, mechanical harvesting, aeration systems, invasive species management, water quality testing, restoration, and many more.
Other methods of harvesting aquatic nuisance plants include amphibious harvesters, spray boats, algae skimming and removal boats. The latest in harvesting technologies include aquatic plant identification and boat-to-shore conveyors.
Mechanical harvesting is by far the most preferred method for the control and removal of aquatic weeds and also solves many other aquatic problems. Professional harvesting companies can offer expert advice on how to manage waterway issues and provide aquatic maintenance services including weed harvesting and algae removal.
