"Western white pine provides habitat for a variety of mammals, birds, and insects. Western white pine comprises less than 1 percent of the winter diet of elk; however, it is browsed by black-tailed deer in the winter when other browse is limited. The seeds of western white pine are an important part of the diet of red squirrels and deer mice.
Western white pine provides nesting, thermal, and foraging cover for a variety of birds; it also provides hiding and thermal cover for elk." 
"Native Americans chewed the resin, wove baskets from the bark, concocted a poultice for dressing wounds from the pitch, and collected the cambium in the spring for food.
Western white pine forests have aesthetic and recreational value. Cones of western white pine are collected for novelty items. The tree is also planted as an ornamental." 
"Western white pine is highly valued as a timber species. Its wood is straight grained, nonresinous, lightweight, and exhibits dimensional stability. These qualities render the wood useful in the production of window and door sashes. The wood is also used in the production of doors, paneling, dimension stock, matches, and toothpicks. The dimension stock works well. It takes nails without splitting, and it takes a nice finish. The wood is also excellent for carving."
