FIRE EFFECTS
SPECIES: Pinus strobiformis | Southwestern White Pine 



IMMEDIATE FIRE EFFECT ON PLANT : 
Fire damaged stems of young (less than 15 years) southwestern white pine
usually die; older trees (more than 50 years) are susceptible to
scarring [2].

No information was found in the literature about the fire susceptibility
of southwestern white pine seeds stored in caches.  It is possible that
soil may sufficiently insulate cached seeds from fire damage.


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Southwestern  white pine may establish after fire through bird-dispersed
seeds.

While southwestern white pine is known to be an important seral tree
following fire, such as in white fir-Douglas-fir (Abies concolor-
Pseudotsuga menziesii)/Gambel oak habitat types, no information was
found in the literature about southwestern white pine rates of recovery
after fire [51].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
Prediction of natural fuel loadings in southwestern mixed-conifer
forests is difficult; much variation exists within and between stands
[58].  Sackett [59] reported average square diameter and specific
gravity for southwestern white pine and other conifers in different size
classes, making the planar intersect method of fuel evaluation
applicable to southwestern forests.

Regeneration by prescribed fire of mixed-conifer series for wildlife has
been discussed in detail [63].
