all grow quickly and spread easily. If le unchecked,
they can cause all sorts of problems, including:
• Create human health concerns due to large mats
that increase mosquito breeding habitat.
• Restrict recreational activities and make boating,
swimming and fishing impossible.
• Restrict water flow, which can impede irrigation,
flood control and hydroelectric operations.
• Limit biodiversity when large masses of the plant
out-compete native plant species.
• Block sunlight and reduce dissolved oxygen in the
water, which makes the water unsuitable for
aquatic organisms.
