Long-term effects of mechanical harvesting on Eurasian watermilfoil [electronic resource] / by Scott Painter. Burlington, Ont. : Aquatic Ecology Division, National Water Research Institute, Canada Centre for Inland Waters, [1986]. [21] p. : ill.

"Eurasian watermilfoil is a nuisance aquatic invaded plant which has invaded many lakes and rivers in Canada. Mechanical harvesting is generally agreed to be the most ecologically sound control method but is criticized because multiple harvests may be required each growing season and no long-term effect on regrowth may be apparent. Environment Canada’s research has examined the short and long-term effects of mechanical harvesting. A previous NWRI report (#85-36) outlined the observed response of milfoil to 19 different harvesting strategies. The most effective cutting scenario was a June/September double cut. A four year long-term harvesting experiment using the June/September double cut strategy was initiated in 1981"--Management perspective.
