Lake Erie Protection Fund Grant Project Final Reports Available

The Ohio Lake Erie Commission announces that the latest round of Final
Reports for Lake Erie Protection Fund (LEPF) grant projects are now
available upon request. The four latest reports listed below as well as all
previous reports are available for viewing at the Library of the Ohio Lake
Erie Commission and the Ohio EPA's Resource Center. To view a comprehensive
list of all available reports, visit the Commission's web site at:
www.epa.state.oh.us/oleo and click on Lake Erie Protection Fund>Final
Reports. To receive a full copy of a specific report, please contact the
Commission at: oleo@www.epa.state.oh.us or call: 419/245-2514.

The Lake Erie Protection Fund was established in 1992 to help finance
research and implementation projects that help protect, preserve, and
improve the quality of Lake Erie. During the last 9 years, over $6 million
has been raised for LEPF projects through sales of the Lake Erie License
Plate and other donations.

The Ohio Lake Erie Commission is comprised of the directors of the Ohio
Environmental Protection Agency and the Departments of Natural Resources,
Agriculture, Health, Transportation, and Development. The Commission was
established for the purpose of preserving Lake Erie's natural resources,
protecting the quality of its waters and ecosystem, and promoting economic
development in the region.

     LEPF 97-23
1. Ottawa River Restoration Project, Casey Stephens, Project Director, City
of Toledo; Division of Environmental Services, Toledo, OH.

The City of Toledo conducted a sediment demonstration-capping project within
a 2.5 acre portion of the Ottawa River, located in northwest Ohio. The
project involved the construction and field-scale testing of different
sediment-barrier designs (caps) along a particular section of the river
known to have elevated levels of PCBs and other contaminants in the
sediments. A principal component of each of the cap designs tested in the
Ottawa River was AquaBlok, a remedial technology developed by New Waste
Concepts, Inc. with Hull & Associates providing the technical assistance and
primary engineering/environmental consulting on the project. AquaBlok is a
patented product resembling small stones that is comprised of a solid, dense
core surrounded by a clay mineral-based coating fixed with polymers. When
applied through a water column and across the surface of contaminated
sediments, AquaBlok acts as a low-permeability and erosion-resistant,
cohesive barrier between the sediments and overlying deepwater or wetland
ecosystems. This project demonstrated capping technology in a flowing-river
environment. Among other field studies, AquaBlok has proven to be effective
in reducing organism exposure to contaminated sediments while offering a
viable substrate for re-establishment of flora and fauna.

2. Pilot Project for Evaluation of Standard Biotic Metrics in Urbanized
Dr. B. Michael Walton, Project Director, Department of Biological,
Geological & Environmental Sciences; Cleveland State University, and Drs.
G.V. Sgro, W.B. Clapham, Jr. and J. J. Johansen, Department of Biological
Sciences;  John Carroll University.

The goal of this project was to compare the performance of biological
metrics and indices as predictors of the effects of urbanization on
ecosystem integrity. Biological metrics and indices were compiled for three
urban/suburban streams. A suite of land use metrics for the watershed was
also compiled from a GIS database. The intent was to evaluate the covariance
among the biological and land use metrics and to assess the most significant
variables affecting the sensitivity of the biological metrics to variation
in landscape characteristics. This project was a pilot of a larger project
for developing predictive models of the effects of the urban landscape on
biological metric scores. The purpose of this pilot project was to indicate
where future efforts may be fruitful and refines the ability to set goals
for urban streams leading to the development of management tools which can
assist in the decision process of remediation efforts.

SG 107-99
3. Daily Foraging Habits of Adult Double-Crested Cormorants as Indicators of
Distribution in Western Lake Erie, Michael Bur, Project Director, and Martin
Stapanian, USGS; GLSC-Lake Erie Biological Station; Tom Seamans and Brad
Blackwell, USDA-Wildlife Services; and Jeff Tyson, Ohio DNR-Sandusky Fish
Research Station.

The population of double-crested cormorants has increased dramatically in
recent years and has been a concern of natural managers and fishers in
western Lake Erie.
The regional controversy is that cormorants may have a negative impact on
fish populations by depleting stocks of game fish (e.g., walleye, yellow
perch, and smallmouth bass.) This project was a radiotelemetry near-shore
study with the objectives being: (1) locate and quantify foraging flocks in
a section of the western Lake Erie basin; and (2) estimate foraging range
and temporal activity patterns of nesting cormorants. Eighteen adult
cormorants nesting on Middle Island, ON. were successfully tracked from May
through October 1999, using aerial and surface telemetry. The researchers
found that gizzard shad, emerald shiner and freshwater drum are the three
most important prey for cormorants. There was no significant association
between the locations of foraging cormorants and the historical densities of
the fish species in Lake Erie. A sound management plan for cormorants in
Lake Erie requires more detailed studies of the associations between
locations of foraging flocks of cormorants and densities of fishes.

4. Disturbance, Vegetation, and Floristic Diversity in a Lake Erie Coastal
     Craig Davis, Ph.D., Project Director and Bradley A. Welch, Graduate
     Associate, The Ohio State University; School of Natural Resources.

Development activities in Lake Erie's western basin have disrupted critical
marsh-lake disturbance patterns. As a result, native plant species richness
has waned while aggressive species abundance has escalated. This project
mechanically disturbed a diked marsh section of East Harbor to activate the
seed bank and the section reconnected to the harbor. In doing so, the
disturbance caused an increase of 12% species richness in the three years
following the disturbance, and the number of species listed as rare or
endangered in Ohio also increased. The project proved the abundance of
Phragmites australis was significantly curtailed. Species richness and
aggressive species abundance have returned to pre-disturbance levels. The
long-term control of Phragmites australis may benefit, not only the wetland
plant community, but also the Park and its visitors through future
educational and recreational activities.
