    Fire Ecology of Pacific Northwest Forests is a historical, analytical, and ecological approach to the effects and use of fire in Pacific Northwest wildlands. James K. Agee, a leading expert in the emerging field of fire ecology, analyzes the ecological role of fire in the creation and maintenance of the natural forests common to most of the. Excerpt from Some Effects of Logging and Slash Burning on Physical Soil Properties in the Corvallis Watershed Other workers in the Douglas-fir region have explored the influence Of logging and slash burning on soils, using somewhat different approaches to the problem. Recently, Tarrant studied the effect of slash burning on rate of water percolation, Size of pore spaces, and bulk.

From the summary 'Slash was burned at three different intensities on north and south slopes of logged-off Astoria Burning Douglas-fir slash book loam in the coastal mountains of Oregon.

Samples of soil were collected two days after burning and thereafter at seasonal intervals for a year. Soil moisture and water-holding capacity were reduced significantly during the year. influence of slash burning on regeneration, other plant cover & fire hazard in the douglas-fir region, a progress report [morris, w.g.] on *free* shipping on qualifying offers.

Morris. Foliar analyses of Douglas fir needles was made in an attempt to evaluate soil fertility and productivity changes caused by logging and slash-burning. No statistically significant differences were found between means of nitrogen, potassium, phosphorus, calcium, and magnesium values of Douglas fir needles from trees growing on logged and logged and slash-burned by: 1.

The Effect of Logging and Slash-burning on the Nutrient Content of Douglas Fir Introduction This study was a portion of a research program to determine how site changes caused by logging and burning of a forest ecosystem affect regenera-tion and productivity of future stands.

One of. A study of the effects of exposure (aspect and slope angle) and natural shade on the moisture content of Douglas fir logging slash indicates that, throughout most of the fire season, such effects are not great enough to be of practical significance in slash hazard rating. In the latter part of the fire season, however, when slash burning is usually done, fuels on north-facing.

The study was conducted on two Douglas fir clear-cuts, one logged in and slash burned in and the other was logged in and slash burned in All sampling was done in ; one and two years after slash burning.

The surface of soil blocks from three sites of the Coastal Western Hemlock Zone were burned at two intensities and planted separately with seeds of Douglas-fir, western hemlock, and western redcedar.

Steele and William R. Beaufait (page images at HathiTrust; US access only). We measured soil heating and subsequent changes in soil properties between two forest residue disposal methods: slash pile burning (SPB) and air curtain burner (ACB).

The ACB consumes fuels more efficiently and safely via blowing air into a burning container. Five burning trials with different fuel sizes were implemented in northern California, : Woongsoon Jang, Deborah S.

Remove the soil from around the base of the pine tree stump by using a shovel. When the bulk of the soil is clear, switch to a hand shovel, and remove the soil from between and around the main. These forests are quite productive and certainly capable of growing medium and large-sized Douglas-fir, ponderosa pine, western larch, and western white pine.

But logging methods in favor during most of the 20 th century led to the removal of the largest and most fire tolerant trees over fairly large areas. Douglas fir trees are considered to be native, but as toby hemenway points out in his book: native to when.

Before the white folks showed up in the US, the douglas fir was considered by the natives as the invasive weed. They would burn them regularly. Anybody else have information along these lines?. Color/Appearance: Black Spruce is typically a creamy white, with a hint of yellow.

Grain/Texture: Black Spruce has a fine, even texture, and a consistently straight grain. Rot Resistance: Heartwood is rated as being slightly resistant to non-resistant to decay. Workability: Easy to work, as long as there are no knots present.

A Guide to Managing Douglas-fir Beetles on Private Property Author: Ministry of Forests Subject: Populations of Douglas-fir beetles (Figure 1) are currently high in the Kootenay Boundary Region.

This beetle infests and kills Douglas-fir trees wherever they grow in British Columbia, especially in the interior regions of the province. Slash is the leftover tree limbs, tops and other residue left by logging activities.

Slash piles are disposed of by burning or chipping. Pile burning: Slash is piled together and burned during safe conditions, usually during the winter after it has been left to season (dry).

Some owners assume slash disposal is a pre-requisite for the completion of any operation. Not true. How logging slash is managed should be part of any written contract, including the type of machinery (dozer, excavator, manual) and method of disposal (windrows, piles, on the landings) or none at all.

Also, burning the slash is a separate issue. A prescribed fire is the planned use of low-intensity fire to achieve very different goals given certain weather, fuel and topographic conditions (Fernandes et al., ).It is seen as a primary, integrated vegetation management option to mitigate wildfire activity and, thereby, of reducing wildfire carbon emissions (Bennet et al., ).Today, one of the primary objectives of prescribed fires Cited by: Douglas-fir Manual The late Leith Knowles, the driving force behind recent Douglas-fir research.

The purpose of the completed logging projects was to thin mistletoe infested douglas-fir, improve overall forest health and reduce the threat of catastrophic wildfire.

Depending on weather conditions, the pile burning may start as early as mid-October but burning operations may. Forest Practices Act. Helping Landowners. Replanting Forests. Non-Motorized Trails. Motorized Trails. Forest Benefits. About Oregon's Forests. Agency Home Page Feature Box 1.

Forest Service research forester Stephen F. Arno discusses why fire management is impeded today and says we need to look at the history of fire policy in tandem with the development of the science of disturbance ecology to gain a better understanding of the issue.

Numerous books. Wood, in the strict sense, is yielded by trees, which increase in diameter by the formation, between the existing wood and the inner bark, of new woody layers which envelop the entire stem, living branches, and process is known as secondary growth; it is the result of cell division in the vascular cambium, a lateral meristem, and subsequent expansion of the new cells.

Even a broadcast slash fire in a clearcut does not give a uniform burn over the whole area. Tarrant (), for instance, found only 4% of a ha slash burn had burned severely, 47% had burned lightly, and 49% was unburned.

Burning after windrowing obviously accentuates the subsequent heterogeneity. INITIAL STAGES OF SECONDARY SUCCESSION IN THE COASTAL DOUGLAS-FIR AND WESTERN HEMLOCK ZONES (logging and slash-burning) rather than on the rate of succession in weed populations after Author: Dieter Mueller-Dombois.Douglas fir forests of the western Cascades were treated the same as the ponderosa pine forests to the east.

In the s, biologists demonstrated that slash burning was harmful to forest regeneration, but laws passed to prevent fires required that slash be torched.In the important Douglas Fir region of western Washington and western Oregon, a large proportion of the lands cut over in the last 20 years have failed to re-stock satisfactorily; this is due partly to uncontrolled fire and partly to other factors.

Douglas Fir produces seed abundantly, with complete crop failures only every 4th and 5th year, but much seed is destroyed by rodents, birds, and Cited by:
