A Biodiversity Atlas of the Lake Huron to Lake Erie
This Biodiversity Atlas tells the story of the natural
communities found in the Lake Huron to Lake Erie Corridor.
The Corridor is made up of the St. Clair River, Lake St. Clair
and Detroit River, as well as the watersheds of southwestern Ontario
and southeastern Michigan that drain into these great waterways.
Water in the Corridor flows from the mouth of Lake Huron through the
St. Clair River, Lake St. Clair and the Detroit River, into Lake
Erie. The tributary rivers, creeks, streams and drains in the
watersheds connect the surrounding lands to the Corridor.
This Atlas is organized according to elevations above sea level -
from lower to higher - from the open waters and tributaries to the
shoreline and lakeplain, and finally to the ecosystems of the
interior lands that drain into the Corridor.
A wide variety of life forms - biodiversity - make the Corridor
unique. The glacial history, climate, soils and water resources have
created a landscape that is home to an incredible diversity of
natural communities: forests, savannas, grasslands and wetlands.
Within these natural communities live species that have global
A goal of everyone involved in producing this Atlas is that
readers will gain a better understanding of this amazing region, and
a desire to play an active role in caring for it.
