AQUATIC PLANTS
In moderation, aquatic plants provide many benefits to aquatic
systems by producing oxygen, providing habitat for fish and other
aquatic organisms, stabilizing bottom sediments and reducing
shoreline erosion.
Problems exist when aquatic plants become too dense and create
ecological and recreational issues. Excessive plant growth can
impede biological interactions, reduce water quality and have
impacts on residential property values.
ASSESSMENT
A number of factors can contribute to excessive aquatic plant
growth. In most cases, several factors have combined to create the
problem. Although excessive nutrients can impact aquatic plants and
algae growth, the introduction of exotic plant species is responsible
for the majority of aquatic plant issues.
Exotic aquatic plants are plant species that are not originally from
this region. Once introduced to a waterbody they can quickly
dominate a system. They have few natural controls and often
crowd out native plant species, interrupt biological interactions and
negatively affect water quality.
To determine what factors are contributing to excessive plant
growth, a vegetation survey is recommended to assess the types,
density and distribution of vegetation in the water body. This survey
allows us to establish a Management Plan and track the results of
management efforts.
It is also recommended to assess the water quality characteristics, as
this will give us a baseline of nutrient levels, water clarity, dissolved
oxygen and other parameters that can be assessed throughout the
Management Program.
