The Great Lakes coastal zone is utilized for spawning,
rearing, foraging and as over-winter refuge for a variety of Great
Lakes fishes. These
habitats have received only limited study.
This makes it difficult to evaluate how impacts to these areas could
affect Great Lake fisheries. A wide variety of methods for measuring
habitat quantity and quality are available.
However, methods differ in terms of accuracy, spatial and temporal
resolution, cost, and applicability to the Great Lakes
region. These differences make it
difficult to accurately gauge what method may be most appropriate for a
particular research or management objective. In this report, we identified and
critiqued the effectiveness of existing techniques used for fisheries habitat
assessment, classification, rehabilitation, and management in the Great Lakes,
and provided analysis that could be helpful for allocating research and
management efforts in the Great Lakes lower riverine and nearshore
regions. We identified several areas
that should receive greater attention: real-time monitoring data in large
coastal rivers and estuaries; detailed local channel habitat data for coastal
rivers; large river floodplain structure and function; high resolution
bathymetry and substrate mapping for the Canadian nearshore
zones; identification of the optimal methods for using remotely sensed data to
inventory coastal wetlands; further research using remote data to estimate
coastal productivity and water quality; and development of a Great lakes
Coastal Habitat Assessment Framework.
The report identifies technologies and protocols that could be used to
address these needs and suggests several pilot projects that could
significantly accelerate the development of coastal habitat inventories,
assessment, and science in the Great Lakes
