Below is a very preliminary
and incomplete list of non-native plants that have been observed spreading
out of cultivation in Marion County. Some of these are aggressive invaders that
are extreme hazards to our landscape, whereas others are only trivial nuisances.
Some of these plants have created serious problems in other regions, but have
not yet done so here. Some are common lawn and garden weeds that only move into disturbed soil. Many
are valuable horticultural or agricultural species that are beneficial in the
right places, but interfere with appropriate management of native vegetation if
allowed to grow on natural lands.
The species
highlighted in yellow are the
invasives currently of greatest concern to Marion County public land
managers. Cogongrass, highlighted in
orange, is the focus of MCISMC's efforts.
The
Florida Exotic Pest Plant
Council's 2005 rankings of the most invasive species are given in the
right-hand column.
We are currently seeking funding to expand this table, adding all reported
species, describing
their status in Marion County, evaluating the
risks they present here, and providing information on identification and
control. If your organization might be able to support any of this work,
please contact Linda Duever at
