Quercus falcata
Southern Red Oak

Mature Height: 70-128'     Longevity: 275 years

1-7 Water Range
Soil moisture tolerated by tree

6-8 Temperature Range
Hardiness Zones in which tree naturally occurs.

DEFENSE     Soil Moisture Key
1: References concur that tree most often found in dry uplands. However a few indications that tree can succumb to drought.

7: No flood tolerance reported. Presence along streams identified. Hydric indicator for tree is FACU-. Close relative called cherrybark oak found in wetter areas which leads to confusing commentary in some literature. Biggest trees on fertile stream bottoms.

DEFENSE
Base Score: low (Big Tree) = 3
Identification in Silvics Manual & Fire Effects (FEIS) database as a fire susceptible tree. Tree also grows relatively slowly & lives short life (ie long proportion as very susceptible sapling). Assign "low" big tree value.
Final Value = 3

DEFENSE
Base Score: ???
Very little data. Deep roots & strong wood lead to positive impression of wind strength. Tree also of moderate size & not a forest giant (w/ long juvenile life). Will assign high value but not highest.
Final Value = 4
