SHORELINE PLANTING PROJECT!
A
group of more than 2 dozen North Carolina Wildlife Federation, Lake Norman
Wildlife Conservationists (LNWC), Duke scientists, and Island adopters met Aug.
23 to plant 1,100 water willows, 100 black willows and 60 maidencane on the
shorelines of several Lake Norman islands in a collaborative habitat restoration
effort.
This is the
BACKGROUND
When Duke Energy built the Cowans Ford Dam in the 1960's, the primary goal was
the generation of electric power. This requires the raising and lowering of lake
water levels dependent on electric power demands. This leaves shorelines on Lake
Norman at varying water levels at different times of the year. Because of a
general lack of fertility of the lake's substrate, shoreline aquatic vegetation
is almost nonexistent.
Island and main lake shorelines are suffering continually from erosion generated
by increasing boat wakes. Plants to help stabilize the islands and main
lake shorelines from increasing bank erosion while providing habitat for aquatic
species such as fish and amphibians have been trialed over the past 3 years.
TRIALS
In 2006, Hugh Barwick and his staff decided to trial a likely looking candidate
species known as water willow. The plant thrives in water depths to a
maximum of just three feet to areas of moist soil on the shorelines. It
spreads into colonies but does not present a boating hazard. Water willow
stems extend above the water level just a few feet.
It is hoped that the plants will anchor the shoreline soil, lessen waves from
boat wakes, and provide cover for aquatic animal species.
Project lead, Hugh Barwick of Duke Energy, said that this year's plantings were
focused on Islands N-1, N-26 and N-27 in order to concentrate the cuttings and
eliminate the blue cylinder enclosures-called cages-previously used to prevent
grazing by aquatic animal life, probably turtles.
Last year's plantings of black willow did not survive as well as the water
willows, Barwick said. "Given drought conditions, there was good survival
of water willow, especially in cages, but some outside of cages, as well,"
he said.
"The weather was nice and the water levels perfect" for the project,
Barwick added.
According to Tim Gestwicki, deputy director of conservation for the NCWF, the
planting effort is an aquatic habitat enhancement project that is part of the
Island Habitat Program. Support came in part from the Catawba Habitat
Enhancement Program (HEP) fund.
SUMMARY
The North Carolina Wildlife Federation, LNWC, and Duke Energy are committed to
establishing aquatic vegetation and shoreline plants on Lake Norman to help
control destructive wave action and provide habitat for fish and other aquatic
species.
A Big Thank You! to all the volunteers
(Mtn Island Lake Wildlife Stewards partnered with the harvest) who assisted with
the project. We will keep you updated on the successes and next phases.
