VALUE AND USE
SPECIES: Pinus leiophylla var. chihuahuana | Chihuahua Pine 



WOOD PRODUCTS VALUE : 
Although of minor commercial importance due to its limited distribution,
Chihuahua pine is used for lumber [22,26,37,39,68].  The best grades of
Chihuahua pine are as good as ponderosa pine for commercial purposes
[30].  The wood of Chihuahua pine is durable but not strong, soft to
hard, light, and straight-grained [39,55,70].


IMPORTANCE TO LIVESTOCK AND WILDLIFE : 
In oak-juniper-pinyon woodland of southeastern Arizona, 36 breeding bird
species foraged for insects on Chihuahua pine and Mexican pinyon
needles; this level of use was higher than would have been expected from
random foraging patterns [4,5].

Chihuahua pine seeds are eaten by thick-billed parrots [68].

Chihuahua pine is codominant with Arizona walnut in open riparian
communities in southeastern Arizona, which acorn woodpeckers use for
nesting [52].

Mexican spotted owls are yearlong residents of oak-pine forests, in
which Chihuahua pine occurs [27].


PALATABILITY : 
NO-ENTRY


NUTRITIONAL VALUE : 
NO-ENTRY


COVER VALUE : 
NO-ENTRY


VALUE FOR REHABILITATION OF DISTURBED SITES : 
Chihuahua pine was planted with 37 other pine species in trials on
sandhill sites in northwestern Florida.  It did not survive [14].


OTHER USES AND VALUES : 
NO-ENTRY


MANAGEMENT CONSIDERATIONS : 
Chihuahua pine was evaluated for suitability as a timber tree at the
Wind River Arboretum in Wyoming.  It was winter-killed after 5 years [60].

Different Chihuahua pine habitat types have differing productivity.
Types located in well-watered positions such as on lower slopes or
alluvial terraces achieve maximum productivity at 80 years.  Drier
habitat types reach maximum productivity at about 100 years [50].

Equations to estimate understory production have been developed for the
oak-pine forests in which Chihuahua pine occurs [26].

Sampling methods that classify riparian communities to which Chihuahua
pine belongs are discussed in the literature [65].

Chihuahua pine was included in a breeding program that studied pollen
production at the Eddy Arboretum in California.  Chihuahua pine produced
pollen during May for 1 year [21].

Chihuahua pine is susceptible to dwarf mistletoe (Arceuthobium gillii
ssp. gillii).  Dwarf mistletoe infection of Chihuahua pine causes
reduced growth rates, increased mortality, and reduced seed production,
and predisposes Chihuahua pine to attack by insects and fungi [31].
