Title: Plant Composition in Lake Munson and Lake Hiawatha


1
Plant Composition in Lake Munson and Lake Hiawatha
  • How does plant composition of Lake Munson compare
    to a more pristine lake?

  • Victor Wiley
  • Kevin Green

Background Information
  • Lake Hiawatha is part of the Bradford Brooks
    Chain of Lakes, an important recreational area.
    The Chain is formed as water flows from Lake
    Cascade into Lake Hiawatha, then to Lake Bradford
    and on into Grassy Lake. Magnificent cypress
    trees surround these lakes. The waters are very
    tannic and acidic.
  • Leon County began the restoration of Lake Munson
    by constructing a storm water treatment facility
    at Lake Henrietta. The facility treats runoff
    before it enters Lake Munson. In addition, Munson
    Slough was upgraded and stabilized from the
    restored Lake Henrietta to the beginning of Lake
    Munson.

Research Question
  • How does plant species diversity and abundance
    differ between Lake Hiawatha and Lake Munson?

4
HYPOTHESIS
  • Lake Hiawatha gets water from natural runoff and
    thus will have higher species diversity and more
    plants overall.
  • Since Lake Munson is a more polluted lake,
    drawing water from urban runoff, it will have
    fewer species and fewer plants in the environment
    because of the urban pollution.

5
Procedure
  • Specify 3 different points along the shore of
    each lake.
  • With a stake mark 7 meters to the left and right
    of the point.
  • At these two points mark 2 meters on and off
    shore with a stake.
  • Divide this created quadrat into three sections
    with string so there are six sections, 3 onshore
    and 3 offshore.
  • Identify and count the number of each plant
    species in each section of each quadrat.

Discussion
  • Sometimes plants clumped together in one
    particular quadrat which is why there may be
    plants in one quadrat but half the number in the
    next.
  • It is obvious that some plants belong on either
    land or water because they show in the data on
    either QL or QW but not both.
  • Large numbers usually indicate that the plant was
    small and plentiful.
  • We noticed a greater variety of plants at Lake
    Munson. Lake Hiawatha only had a few plant
    species but was very abundant when it came to
    those plants.

9
Improvements
  • We could have more than one type of plant
    Identification just in case a plant isnt in one
    book.
  • Have more than one person count plants each time
    for a more accurate count.

10
Conclusions
  • Our hypothesis stated that because Lake Munson is
    polluted, the more fragile plants that cant
    handle the pollution in Lake Munson would survive
    in a less polluted Lake Hiawatha along with the
    more durable plants who can handle both lakes.
    However, our initial survey found that Lake
    Hiawatha had fewer plant species possibly due to
    being out-competed for nutrients by the large
    Cypress trees in the lake.
  • We would need to make a more complete survey of
    both Lakes before being able to draw a
    generalized conclusion to our research question.
  • We could also improve our investigation by
    determining how much of the plant composition at
    both lakes was native versus exotic species.

Possible Sources of Error
  • Counting errors
  • Misidentifying different plant species
  • Mismeasuring quadrants
