General information
Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.
MLRA notes
Major Land Resource Area (MLRA): 101X–Ontario-Erie Plain and Finger Lakes Region
Most of the MLRA is a nearly level to rolling plain. Low remnant beach ridges are commonly interspersed with a relatively level lake plain in the northern part of the area. Drumlins (long, narrow, steep-sided, cigar shaped hills) are prominent in an east-west belt in the center of the area. The Finger Lakes Region consists of a gently sloping to rolling till plain. Elevation increases gradually from the shores of Lake Ontario and Lake Oneida to the Allegheny Plateau, the southern border of the area. The bedrock underlying this area consists of alternating beds of limestone, dolomite, sandstone, and shale of Ordovician to Devonian age. Most of the surface of the area is covered with glacial till or lake sediments. The texture of the lake sediments is silt, loam, or sand. Ancient beaches, formed at different lake levels, form ridges along the shoreline of Lake Erie and Lake Ontario. Stratified drift (eskers and kames) and glacial outwash deposits are in many of the valleys. A large drumlin field occurs in the Finger Lakes Region.

Ecological site concept
Landform/Landscape Position:
The site occurs in depressions within lake plains. Slopes range from 0 to 2 percent.
Soils:
The site consists of very deep, poorly drained and very poorly drained soils formed in glacial outwash deposits. Soils are typically moderately coarse to coarse textured. Representative soils are Barre, Canadice, Canandaigua, Fonda, Getzville, Granby, Lakemont, Madalin, Raynham, Shaker, and Uwihreh mapped within MLRA 101.
Vegetation
The reference community coincides with NatureServe's Black Ash - Red Maple Swamp Forest (CEGL007441).
