Most higher plants have evolved with an obligatory symbiotic relationship with my corrhizal fungi. Epigeous mycorrhiza formers have their spores dispersed by air currents, but hypogeous mycorrhizal fungi are dependent upon small mammals as primary vectors of spore dissemination. Mammalian mycophagists defecate within the coniferous forest ecosystem, spreading the viable...

The response of western hemlock (Tsuga heterophylla [Raf.] Sarg.) to two methods of site preparation for planting was compared. One site was cleared of mature brush by the "brown-crush-and-burn" method. The other was partially cleared by spraying with herbicides. Seedlings lifted and planted in December, January, February, and April were...
Monitoring soil density on three sites during repeated trips with a high-speed skidder showed that: During the first 20 trips, soil density primarily increased between depths of 2 to 4 inches; Density increased most during the first few trips; Density continued to increase slowly in amount and depth with the...
