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. |
