FIRE EFFECTS
SPECIES: Pinus lambertiana | Sugar Pine 



IMMEDIATE FIRE EFFECT ON PLANT : 
Sugar pine is rated as intermediate in fire tolerance.  Young sugar
pines are susceptible to low- to high-severity fires.  Mature trees can
survive most fires, suffering only bole scorch.  Sugar pine
susceptiblity to secondary attack by insects and disease following fire
is rated as low [3].



DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Sugar pine reaction to a low-severity fire is by seeding on the exposed 
mineral soil, thus enhancing germination.  High-severity fires that occur 
during periods of high stress will generally result in death [3,16].



DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
Prescribed burning has been found to be an effective management
treatment that will destroy infected stands of sugar pine where dwarf
mistletoe and other diseases have rendered stands unmerchantable [1].
Dead sugar pine is susceptible to blue stain fungus in the sapwood;
however, the heartwood is very durable.  Salvagable trees may be found
up to 17 years after being killed by fire [15].
