Since then, the Reforestation of grand fir problem has decreased in a stands with Douglas fir would few areas, but grown progres seem to solve the problem sively more severe in many others. Now the aphid is dis tributed from southern Brit ish Columbia to Crater Lake National Park in Oregon. It appears to be confined to the west side of the Cascade range, and climate seems to be its most important limiting factor. What the aphid lacks in size (it measures about 1/25 inch in length) it makese up for in numbers. Two to four generations per year are com mon in Oregon, and one fe male can produce up to 10,000 offspring in a two-generation year. Populations of the Bal sam Woolly Aphid consist en tirely of females. There are never males. Reproduction Is carried out without fertiliza tion through a process called parthenogenesis. Reproduction in this way is very efficient and huge numbers can be pro duced. The aphids get part of their name from a white material that can be seen covering the Now hoar thia... insects and their eggs on the bark of the tree. In heavy in Hapo yair halidayi festations. the wool looks like frost on the tree arc happy days. The aphid inserts its thread like mouth parts through a thin place on a tree’s bark. This "sucking tube ” Is two or three times its body length. Salivary injections at the feed ing point are what cause or stimulate the abnormal tree growth. There are basically two ways in which the insects infest a tree by crown attacks and trunk attacks. In one the aphids infest the twigs in the crown. This causes swelling around the buds called gouts. Eventually bud growth Is in hibited and the tree slowly Ore.

The subalpine fir is not particular ly valuable as a timber tree. It will be missed mast by those who see it as the symbol of the high wilderness; for whom its spire-like shape suggests a sense of eternity and peace. The Baslam Woolly Aphid is a rapidly approaching threat to the Olympic National Park and the newly formed North Cascades National Park. These recreational forests may soon suffer the fate of Rainier and Crater Lake National Parks where the alpine fir is already doomed, unless a workable so lution can be found soon Peace on earth good will toward men..
