Wetland Invasive Species &
Cella (pronounced CHEL-luh). Cella is our invasive species
program mascot, a Galerucella beetle. Cella eats purple
loosestrife - only purple loosestrife, and we are helping Cella
to eat up the purple loosestrife in Wisconsin through our program
"See Cella Chow!"
loosestrife may look lovely, but the invasive plant is unwelcome
in Wisconsin's wetlands. The plant, Lythrum salicaria,
invades wetlands and out-competes the native vegetation, producing
a dense monotypic stand. The plant is a hardy, flowering perennial
that was introduced to North America from Europe. It was brought
over in ship ballast and imported as a popular garden plant and
a medicinal herb. It is reported to be useful for treating diarrhea,
dysentery, sore throats, and leucorrhea, and for washing wounds.

During the 2002 and 2003 summers, WWA, with the support of the
Wisconsin Coastal Management Program and the help of more than
twenty natural resource agencies, conservation and education organizations
and individuals, coordinated road and waterway surveys of 27 Wisconsin
counties. More than 200 volunteers logged found more than 800
infested areas. The results of their initial survey efforts can
be found on the Great Lakes Indian Fish & Wildlife Commission's
- for the 2003 county-by-country reports, click

Thanks to continued funding from the Wisconsin
Coastal Management Program and the American
Transmission Company and new funding from the Great
Lakes Protection Fund, We
Energies Foundation, and Dairyland
Power Cooperative, the program expanded in 2003 in several
important ways . . .
More counties: WWA offered nearly 50 training sessions
throughout much of the state in July and August when Purple Loosestrife
was in bloom and easily sighted. We covered 14 counties that the
2002 survey didn't reach. If you would like to add your county
or community to the updated survey area, WWA can provide you with
a training CD that can help you to conduct your own local survey.
goal is to create a grassroots solution to our growing invasive
species problem. By providing technical and financial support,
we are enabling local lake associations, 4-H clubs, and paddling
groups to take a stake in the health of Wisconsin's waterways.
Another problem species: Phragmites australis,
also called Common or Giant Reed Grass, is another invasive species
that concerns Wisconsin Wetlands Association and the state. We
gathered some data on Phragmites in our coastal counties in the
Grants for local groups: WWA gave away more than $5,000
to groups and individuals to coordinate and conduct research on
purple loosestrife biological control.
Educational materials: Developed as a teacher's resource,
Cella Chow!: A Purple Loosestrife Biological Control Manual for
Teachers is now available as a PDF file from DNR's website
and is also available in print.
