Location and Habitat

Location Accuracy (meters):

0-25

Habitat Type:

Grassland/Meadow - Meadow, open, grasses dominant

Habitat Type Notes:

This area is grassland/meadow transitioning into shrubland/meadow with autumn olive and bush honeysuckle slowly expanding. The spoil hill is leftover soil/rock removed from the spillway during construction in the 1970's that was open meadow for many years, now with a mowed path allowing access. Non-native cool-season grasses dominated the area. Small pockets of native wildflowers have been planted along the path, and native red cedar are also prevalent. The lower areas are moist to wet much of the year. Three small vernal pools have been developed in the area.
