3: Found in some uplands but apparently does not tolerate very dry conditions. Only low or marginal drought tolerance indicated.

7: Does not tolerate very wet conditions and no real flood tolerance indicated. Most common in mesic well-drained areas.

DEFENSE (from Distribution Maps)

TOTAL SCORE (6.1): Same score as American Basswood and places in right ballpark as growth comparisons identified in Silvics Manual.

TOTAL SCORE (7.6): Occurrence on much broader range of soil orders increases shade tolerance score over American Basswood.


   

2   Fire Strength

2   Wind Strength

DEFENSE
Base Score: none-low (Big Tree) = 2-3
Tree is identified as very susceptible to fire with generally poorer descriptions of fire resistance in Silvics Manual & lower rating in NRCS Plants database. Lack of other information to boost rating as was done with American Basswood. Will assign lowest Big Tree.
Final Value = 2

DEFENSE
Base Score: ???
(Same as American Basswood) Very little data. Wood is listed as soft & light and tree apparently susceptible to decay when damaged. Tree can grow very tall and not particularly long lived. Tree also appears to do better in sheltered areas. Will assign 2nd lowest value or lower mid value.
Final Value = 2
