FIRE EFFECTS
SPECIES: Tsuga canadensis | Eastern Hemlock 



IMMEDIATE FIRE EFFECT ON PLANT : 
Low-severity fire readily kills seedlings and saplings of eastern
hemlock, and may also kill larger trees.  A low-severity ground fire in
a northern hardwoods community in south-central New York killed 93
percent of the eastern hemlock saplings.  Sixty percent of the mature
eastern hemlock died or were badly injured as a result of the fire [58].
The presence of fire scars indicates that larger trees have thick enough
bark to survive low-severity surface fires [18,36].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Eastern hemlock appears to invade burned sites over time.  In the Pisgah
Forest in southwestern New Hampshire, 80 percent of old-growth hemlock
germinated within the first 37 years after a major fire in 1665 [23].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
NO-ENTRY
