A survey of natural regeneration of Doug1as-fir and associated species was made on 15 staggered-setting cuttings four and five years after logging. These areas were on the H. J. Andrews Experimental Forest which is located in the McKenzie River area of western Oregon. Five types of cuttings were represented: (1)...
The fleshy carpophores of fungi fruiling, on soil and litter were collected from watersheds 2, 3, and 10, IBP sites located in the H.J. Andrews Experimental Forest near Blue River, Oregon (122° W, 44° N). No effort was made to systematize collections: all
carpophores in fresh condition seen were taken....
Forty-nine genera and ninty-eight species of Lichenized fungi are reported from the H. J. Andrews Experimental Forest (Oregon). Substrates, growth form, and type of phycobiont are indicated for each taxon.
Field and laboratory studies are being conducted to describe the hydrologic properties of soil and to determine the timing pathway of precipitation and snowmelt water as it moved through forested soil on a steep slope. Hydrologic properties include hydraulic conductivity, porosity, pore-size distribution, moisture characteristics, stone content, and soil depth....
Populations of mites and.nematodes were monitored on Watershed 10, H. J.
Andrews Forest. A minimum of 50 families and 60 genera of mites are
present, the majority being Cryptostgmata. Population estimates vary
from 5000-350,000 per square meter. Nine categories of nematodes are
present, most belonging to the saprozoic, dorylaimoid, aquatic...
During Biome 1, our primary objective was identification of the dominant fungi involved in litter decomposition. Two survey methods
were used: (1) a survey of macrofungi occurring on Watershed 2 based on fruiting bodies collected and cultures; and (2) a survey of microfungi on decomposing foliage based on cultures isolated...
