Canadian Journal of Forest Research, Vol Number 6, pp. Busse, Matt D.; Riegel, Gregg M. Response of antelope bitterbrush to repeated prescribed burning in Central Oregon ponderosa pine forests.
Postfire logging recoups the economic value of timber killed by wildfire, but whether such forest management activity supports or impedes forest recovery in stands differing in structure from historic conditions remains unclear. The aim of this study was to determine the impact of mechanical logging after wildfire on soil bacterial and fungal communities and other measures influencing soil Cited by: Silviculture involves managing and handling the forest in view of its silvics. Silviculture imitates a natural change - such as a windthrow, beetle infestation, or fire. However, silvicultural methods harvest forest products for human use rather than wait on nature to burn them, eat them, or blow them down.

Gardening in Central Oregon's climate Behind the beauty of the High Desert landscape lie many factors that create challenges for gardeners. Some of the main factors that contribute to difficulties include temperature, precipitation, soil types, elevation, USDA hardiness zones and microclimates.
Silvicultural treatments represent disturbances to forest ecosystems often resulting in transient increases in net nitrification and leaching of nitrate and base cations from the soil.
Response of soil carbon (C) is more complex, decreasing from enhanced soil respiration and increasing from enhanced postharvest inputs of by: In central Oregon, both ponderosa and lodgepole pines are associated with pumice soils.
In eastern Oregon, ponderosa pine is more often associated with basalt- and andesite-derived soils; while lodgepole pine, western larch, interior Douglas-fir, mixed conifer, and spruce-fir types are associated with volcanic ash soils (Geist and Strickler ).
Effects of Silvicultural Practices on Soil Carbon and Nitrogen in a Nitrogen Saturated Central Appalachian (USA) Hardwood Forest Ecosystem January. Samples were collected from the soil surface down to a one meter depth from each of 45 soil profiles, and soil samples were obtained at 10 different soil depths of 0–10, 10–20, 20–30, The results showed that the movement of vehicles had a major impact on the soil condition, while the silvicultural treatment had a clearly defined impact, but one which was quickly recoverable.

The study area lies at elevations of ft., is mantled with pumice deposits 1/2 ft. deep, and has precipitation totals of in. Six plant communities were identified in the Pinus ponderosa and Abies concolor zones; they were, in order of increasing effective moisture content: (1) P.

Highlights Biological soil crust lichen communities are poorly known. We studied 59 sites in Oregon, USA to examine environmental gradients associated with biotic crust lichen communities. Species-rich biotic crust lichen sites were scattered throughout the region.
Richness was weakly negatively related to abundance of shrubs of disturbed sites, Gutierrezia and Chrysothamnus.

SOILS AND FARMING PATTERNS OF THE CENTRAL PUMICE REGION R. GORDON Farm Advisory 0 ff icer, Taupe INTRODUCTION TAUPO has evolved as a region of New Zealand with unique features. The volcanic ash covered some 9, square miles and the soils which developed, though young in geological age, were.
Silviculture is an applied science that requires a synthesis of knowledge about forest dynamics, mensuration, ecology, plant physiology, soils and entomology.
It is in the practice of silviculture that much of the scientific knowledge about forests is applied. If there is adequate moisture, grand fir in central and eastern Oregon grows on pumice and other shallow, exposed soils. On the Mendocino Coast of California grand fir occurs on soils of pH 5.
Elevation: Grand fir occurs at elevations up to 6, feet (1, m) in the Cascade Range and northern Rocky Mountains [14,71]. for lightweight aggregate in Oregon, but process ing of the pumice is necessary to obtain a suitable size distribution of the particles.
INTRODUCTION During two weeks in Octobera field in vestigation of the pumice deposits of the Klamath Indian Reservation, Klamath County, Oreg., was made by geologists of the Geological Size: 1MB. Effects of Silvicultural Practices and Wildfire on Productivity of Forest Soils a high heartwood to sapwood ratio persist the longest.
These results point out the hazards of extrapolating research infor-mation from one ecosystem type to another. Interactions Soil porosity, organic matter, and surface soil volume are highly interdependent.Soil Management as Silviculture.
Because tractor piling does impact the soil layers through displacement and compaction, tractor piling of logging debris can adversely affect tree growth (Bosworth ). Soil bulk density recovery on compacted skid trails in central Idaho. Soil Science Society of America Journal. Forest management practices that lead to frequent entries appear likely to compact these volcanic ash soils.
Depending on logging patterns, large areas could be impacted without careful planning It appears that compaction effects are long-lasting and cumulative, thus the risk of reducing long-term site productivity is a : Robert T.
