      Douglas-fir Forests of Western Oregon the Young Stand Thinning and Diversity Study was designed to test the effectiveness of modified thinning in acceleration of late-successional structural characteristics. Thinning treatments included: a control, a light thin (typical of standard commercial response following alternative thinning. A second goal is to document the effect of prescribed burning on rare, threatened, or endangered species. We review current literature on studies that address effects of prescribed fire and thinning treatments on understory vegetation The results of this synthesis illustrate several important by: 2.

      of fire behavior, and (2) effects of the thinning and burning on soil moisture and temperature, light, and vegetation. The thin-and-burn treatment, relative to the control, generally resulted in more light, higher soil moisture, higher seasonal soil temperatures, but no short-term effects on oak-hickory by: Without fire, such ecosystems converge toward sterile monocultures. Recent efforts to prohibit fire in fire-dependent communities have contributed to more intense and more damaging fires. For these reasons, foresters, ecologists, land managers, geographers, and environmental scientists are interested in the behavior and ecological effects of fires/5(3).

        Leaf nitrogen content (N mass, %) and leaf mass per area (LMA, g m −2) are two important features that are closely linked to the photosynthetic performance of plants and, thus, the NPP of forest ecosystems. Forest management practices, such as burning and thinning, change stand structure and soil dynamics, which may result in changes in N mass and LMA. The objective of this .   This topic includes information on fuel treatments, prescriptions, and sampling techniques applied to the landscape. It covers implementation of a treatment, description of physio.

Forest managers can apply different possible fuel treatments, such as thinning, pruning or removal of surface fuels, using mechanical tools or prescribed fire, to mitigate the potential wildfire severity, modify stand structure and restore forest functions (Fulé et al., b, Agee and Skinner, ).It is known that altering fuel loads and fuel continuity through Cited by: 7.

Introduction. Ponderosa pine (Pinus ponderosa) and Jeffrey pine (Pinus jeffreyi), alone or in mixed forests with other conifers or broadleaved species, range over approximately 10 million ha of western North America, forming forests of great ecological and social pines are adapted to a disturbance regime of frequent surface fires (Keeley and Zedler,Stephens et al., Cited by: Fire, thinning, and the carbon economy: Effects of fire and fire surrogate treatments on estimated carbon storage and sequestration rate Article in Forest Ecology and Management (8) IMPACTS OF TREATMENTS ON FOREST STRUCTURE AND FIRE BEHAVIOR IN DRY FORESTS Forest managers are increasingly using mechanical treatments in dry forests of the western US in order to produce stands with spatially complex structure while also reducing crown fire potential.

However, there has been a lack of evaluation of these treatments on. prescribed fire and thinning treatments on understory vegetation. The studies’ outcomes are presented in two sets of tables: (1) functional group results, and (2) species-specific results. Managers often are interested in and need to report the effects of treatments on.

The effects of fire could range from underburns similar to those in ponderosa pine, to stand-replacing crown fires. At still higher elevations, cold, moist environments support forests that are apt to be comprised of subalpine fir and Englemann spruce, where average times between fires might range up to several hundred years, with a high File Size: KB.

Fuels reduction efforts like this are especially effective in areas where historic management practices, including fire suppression, grazing and harvesting, caused extensive changes in forest vegetation. treatments in southwestern conifer forests in the United States affect wildlife density and population and qualitative reviews that described effects of thinning and fire on multiple wildlife species (Lyon et al.,Pilliod and Bull,Chambers How do thinning and burning treatments in south-western conifer forests in the United.

Thinning trees/shrubs near homes, combined with a reduction in home flammability by installation of metal roofs, removal of flammable materials adjacent to homes, and other measures can virtually guarantee a home will survive even a severe high intensity forest fire.

Thinning forests for fuels reductions, unless strategically done, is a waste. There are no fuels treatments proposed within this project, therefore this research was not addressed.

Overstory Response to Alternative Thinning Treatments in Young Douglas-fir Forests of Western Oregon Abstract An increase in land dominated by young second-growth Douglas-fir forests in the Pacific Northwest has coincided with heightened concerns over loss of old-growth habitat.

There’s hot debate over whether or not to conduct prescribed burning and mechanical thinning (the manual removal of trees) in our nation’s forests. Supporters of these fuels reduction methods, which remove highly flammable undergrowth, argue that they help lower the severity of wildfires.

Meanwhile, opponents say that the treatments can hurt the environment.
