>Abstract: The presence of purple loosestrife plants in wetlands can
> displace wildlife species from this form of habitat.
> Herbicide use and seeding of competitor plant species
> were evaluated as control measures against purple loosestrife.
> Results showed that the herbicide used was effective in
> reducing the frequency of purple loosestrife by 44% and its
> population density by 94%. However, introduction of
> competitor plant species did not reduce have significant
> effect on purple loosestrife.
