Revegetation-microhabitat relations in the blast zone of Mount St. Helens

Creator:: Gallant, Alisa L.
Abstract:: The Mount St. Helens eruption of May 18, 1980, offered an excellent setting for evaluating early response of ecosystems to disturbance. Prior to the eruption, the area was densely forested with fir, hemlock, and Douglas-fir, and various understory species. During the course of the eruption, hillslopes within a 180 degree...

Selected life history aspects and habitat use by Merriam's wild turkeys in Oregon

Creator:: Lutz, Robert Scott
Abstract:: Habitat use and reproductive success by Merriam's wild turkey (Meleagris gallopavo merriami) were studied in Wasco County, Oregon, during 1981-82. This low density turkey population selectively used forested cover types characterized by a variety of structural features, species, and age classes. They avoided monotypic forested cover types, used non-forested cover...

Fire history in three vegetation types on the eastern side of the Oregon Cascades

Creator:: Bork, Joyce L.
Abstract:: Historic fire return intervals in three different vegetation types dominated by ponderosa pine (Pinus ponderosa Laws.) were determined using fire scarred trees. Dendrochronological techniques were used to achieve accuracy in dating fire scars on samples collected from six 40 acre plots established in each site. Mean fire return intervals (MFRI)...

Mycorrhiza formation and diversity in undisturbed forest and clearcut and burned areas in three forest types in Oregon

Creator:: Brainerd, Richard E.
Abstract:: A greenhouse bioassay was used to compare ectomycorrhiza formation and diversity in soils from undisturbed and clearcut and burned areas in moist mesic, moist montane and dry montane forest types representing a gradient of environmental harshness. It was hypothesized that mycorrhiza diversity decreases with increasing environmental harshness and that stability...
