Abstract
The present disclosure relates to systems and methods related to the suppression of invasive plant species by laying down a fabric over beds of such invasive plants. A watercraft with a fabric laying mechanism is provided with the mechanism automatically guiding the fabric from a fabric stockpile to a frame that spreads the fabric prior to the fabric being laid over the underwater plant bed. The watercraft may be provided with a device for dispensing material over the fabric that has been laid down to weigh down or hold down the fabric. Preferably, the fabric is biodegradable and the material is natural to the area. In one implementation, the fabric (e.g jute burlap) is coarsely woven from natural plant fibers.
