An Integrated Habitat Classification and Map of the Lake
Erie Basin Data Catalog
Terrestrial, inland lakes and tributaries, and wetlands habitat
subcommittees worked together to identify common variables and/or geospatial
datasets that would apply to all “land-based” environmental
zones and functions. Similarly, the coastal margin, nearshore, and open-lake
offshore habitat subcommittees worked together to identify common variables
and/or geospatial datasets that would apply to all “waterbased”
environmental zones and functions.
The table below summarizes “common”
environmental variables or datasets that were identified during the
workshop discussion. Attributes for each environmental zone are crosswalked
into these common variables on the left side and the variables are linked
to their descriptions and repective data sets listed below the table.
Not all variables are represented with map data as of yet, but we hope
to fill these gaps in the near future.

Integrated US/Canada Habitat Zones
Habitat zones were delineated by combining Lake Erie watersheds
with isolines queried from a bathymetric grid and converted to polygons.
Terrestrial areas (land, lakes, and streams) were mapped with polygons
representing the coastal margin (water depths 3 m or less), nearshore
areas (water depths 3 m to 15 m), and offshore areas (water depths 15
m and greater).
