Disturbance response:
Fire: Red maple is favored when fire is suppressed
and, in many of the forests where it occurs it has increased in dominance
dramatically during the past decades. The fire interval for red maple is
long (many decades to centuries) and low-intensity surface fires are typical.
A thin-barked species, red maple is susceptible to damage, topkill and
mortality from fire. Saplings are more susceptible than larger, thicker-barked
individuals. Fire effects vary according to season of burning; red maple
is most susceptible in late spring to early summer. Topkilled seedlings
and trees sprout vigorously and rapidly from dormant buds on the root crown.
Seedling establishment may occur from surviving trees onsite or from offsite
seeds carried by wind. This species may assume increased prominence after
a single (unrepeated) fire. Prescribed fires, particularly multiple fires,
have been used to control red maple but as trees become larger and bark
thickens, they become more resistant.
Air pollution: Red maple is tolerant to intermediate
in sensitivity to sulphur dioxide and tolerant to ozone, but response varies
among populations. Symptoms of foliar injury have been noted in areas of
high ambient ozone. Seedlings of red maple exhibited reduced height growth
under controlled fumigation with ozone.
