[[August]] and [[September]] are the main seasons for when western white pines become ripe. When the cones are ripe they will turn a yellowish color. At the age of 7 the western white pine is able to produce its cones, and it can keep this process up until its 70 years old. The cone beetles are the trees worst fear they can cause practical to almost complete failure in the cone production. There are also moths that can cause a loss in seed growth. The seeds can survive harsh conditions when off of the branches of the western white pine; they can still be useable even after a whole winter. Studies found that you can keep the seeds viable for 20 years off the branch if you store them at -18C (0F) to -15C (5F) | [[August]] and [[September]] are the main seasons for when western white pines become ripe.

The Western White Pine will occur in mostly Idaho and Northern Rockies. If you search for a Western white pine you will most likely see the pine in lower elevations growing. In Vancouver you will find many white pines because of the drier parts.[http://www.bcadventure.com/adventure/wilderness/forest/westwhite.htm]Western Mountain ranges thrive on white pines; they will grow on the mountain ranges from southern British Columbia and southwestern Alberta. Also Montanan and eastern Oregon. These types of species will grow in many different soils, but the best soils for these pines are deep, well-drained and medium texture drained soils. The pine grows from sea level to about 2,500 feet above sea level.[http://www.bcadventure.com/adventure/wilderness/forest/westwhite.htm] | The Western White Pine will occur in mostly Idaho and Northern Rockies.

The western white pine was brought into the production line in 1920. The largest recording was in 1937 when 563 million broad feet was produced. But in 1980 the cutting amount was shortened the production was 200 million feet annually. [http://www.fpl.fs.fed.us/documnts/usda/amwood/258wwhpi.pdf]The leading state in producing white pine wood is Idaho. It also is the leader in plywood production. In the mid 1920’s there was put out a major Impact about introducing a pathogen, they have tried to make it to white blister. The method was shortly shut down in 1968 because it took to much effort to keep this processing to going. The biggest threats to the western white pine that could make them die are fire, insects, and diseases. [http://www.fpl.fs.fed.us/documnts/usda/amwood/258wwhpi.pdf]The tree is somewhat fire resistant, but not fully resistant. There is a disease that is very common that will infect the western pine its called the “blister rust”. The disease will occur when the roots start to deteriate and then this makes the tree unable to get water to the vital organs in the tree. | The western white pine was brought into the production line in 1920.
