, Fraxinus americana, Prunus serotina, Elaeagnus umbellata, and Rosa multiflora.
Crataegus mollis is the most commonly occupied corticolous substrate, weathered dolomite is the most common saxicolous substrate and weathered wood is the most common lignicolous substrate.
The woody vegetation consists mainly of thickets of Crataegus mollis.
The woody vegetation includes second growth woodlands (Celtis occidentalis, Crataegus mollis, Maclura pomifera and Populus deltoides) as well as a few groves of oaks (Quercus alba, Q.
Lichens were more common in sunnier areas along edges of woods or on open grown Crataegus mollis and Rhus glabra.
Second growth forests (Acer negundo, Crataegus mollis, Gleditsia triacanthos, Maclura pomifera, Populus deltoides, Prunus serotina, and Ulmus americana) cover most of the remainder of this site.
Scattered second growth woodlands (Acer negundo, Celtis occidentalis, Crataegus mollis, Fraxinus pennsylvanica var.
