The impact of the new harvesting methods on soil with respect to soil disturbance is largely unknown. One objective of this study was to determine the extent of soil compaction and disturbance to the organic cover of the soil resulting from the use of mechanical harvesters and rubber-tired skidders during logging operations in north-central Maine.

The family includes those pore fungi whose fruiting bodies are tough, leathery or woody and whose pore layer usually cannot be separated easily from the context. The pores on the undersurface are only exterior openings of tubes bearing spores and in each species these tube mouths, or pores, are a definite shape and size. Occasionally pore walls will break up giving the appearance of teeth or gills. Fruiting bodies can be sessile, stemmed, effused-reflexed or resupinate (Fig . 2). Members of the family can be either perennial or annual, with the annual species growing during the summer and maturing that …
