The Harmful Effects of Milfoil on Belgrade Stream
Once established, variable-leaf milfoil is extremely difficult to remove. Harvesting can sometimes exacerbate the spread by creating more fragments. As many homeowners and long-time recreational users of the stream already know, this highly-invasive plant has created many difficult challenges.
Ecological Damage of Milfoil
Displaces Native Plants:
It grows rapidly, forming monocultures that outcompete native plants for light and nutrients.
Oxygen Depletion:
Dense mats prevent wind from oxygenating deep water and, upon decomposition, consume nearly all dissolved oxygen, creating anoxic conditions that kill fish.
Reduced Biodiversity:
The infestation decreases the quality of fish spawning areas and significantly reduces the number of native fish and macroinvertebrates.
Habitat Alteration:
It creates stagnant, thick vegetation that serves as ideal breeding grounds for mosquitoes.
Recreational & Economic Damage of Milfoil
Impedes Recreation:
Dense beds make fishing, swimming, and boating difficult, as plants wrap around boat motors and entangled swimmers.
Reduces Property Value:
Infested water bodies often see reduced waterfront property values (by as much as 20–40%) and high management costs.
Rapid Spread of Milfoil
Fragmentation:
The plant spreads quickly when pieces (fragments) break off—via boat traffic or wind—and grow into new plants, allowing it to colonize new areas.
“Belgrade Stream has developed the worst infestation in the entire state. Efforts are underway to protect and restore this valuable waterway.”
