Douglas-fir forest with mixed understory. Douglas-fir-dominated forest is characterized by a significant component of hardwood trees, usually California bay (Umbellularia californica), but tanoak (Lithocarpus densiflorus) or individual coast live oaks (Quercus agrifolia) may be shrub understory is highly variable, but is usually moderate to very dense. heavy cover or debris dictate it, slash burning should be done; otherwise not. Burning tends to favour Douglas Fir reproduction in compe-tition with Hemlock, Cedar, Spruce and the Balsam Firs, particularly after partial cutting. But slash disposal in general is extremely difficult following partial cutting, and may do more harm than good.
Residential service is billed quarterly in advance. Curbside recycling is not available at this time, however, recyclable materials can be taken to free drop off locations throughout the county. We provide per-can or tote collection of normal household refuse (municipal solid waste) and yard waste, excluding. Since previous studies show conflicting results regarding the impact of clear-cutting and slash burning on soil respiration rate, which varied with site conditions and fire intensity, there appears clear need to improve the understanding of the effects of clear-cutting and slash by: 1.
A variation of clear-cutting in which a strip of trees is clear-cut along the contour of the land, with the corridor narrow enough to allow natural regeneration within a few years. After regeneration, another strip is cut above the first, and so on. From the summary 'Slash was burned at three different intensities on north and south slopes of logged-off Astoria silt 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.

Lopping is the cutting of limbs, branches, treetops, small diameter trees, or other woody plant residue into lengths so that the remaining slash will lie close to the ground.

After 8 years the slash piles had scarcely begun to rot and were a distinct fire danger. Kittredge and Belyea (7), working in the Adirondacks where 75 percent of the trees that had been cut were spruce, found slash evident on all areas that had been cut less than 14 years, and on one area 30 years after cutting.
The forestry slash – scrap timber, branches and off cuts left behind in a felling area – that crashed through houses near Tolaga Bay early Monday morning was a. Munger and Matthews (1 ) determined that fine fuels in Douglas-fir slash plots aver- aged 64 cords per acre, or 5 tons.
We estimated the fine fuels on our study areas ranged from tons per acre in addition to the measured tonnages shown in table 1. statement of the minimum requirements for the management of Douglas fir based on our own findings and those of other organiza- tions working with similar forest conditions.
- Slash Fires 1. The burning of slash is usually necessary as a protective measure. Steve DeCook, DNR Fuels Specialist, Northeast Region In the last few years, a significant effort has been underway to improve the health of Washington’s forests and reduce fuel loading by reducing stems per acre.
Funding from state and federal agencies is available through cost-share programs to help landowners thin, prune, and clear excess brush from.
Forest regeneration needs to be applied under the direction of silvicultural prescriptions and the context of silvicultural systems.
Management interventions should be implemented if the current or expected stand conditions are unfavourable for target species to achieve management objectives. To illustrate these concepts, this paper uses coastal Douglas-fir (Pseudotsuga menziesii var Author: Qinyu Cai.
Smoke from these fires is suspected as a trigger of asthma and other breathing complications. If the pile is dry, a fire can burn out of control, jeopardizing the entire woodlot. Better to scatter slash and let nature take its course.

A large number of the loggers in the Douglas fir redon practice clear cutting, that is, cutting everythin on the area to be logged. One can readily imagine the amount of waste which will result from this practice.

The forests of the future should be composed to a large degree of this species, and in the Douglas fir type proper forest management will be directed toward this end. Other species, such as hemlock, cedar, and silver fir, will come in to some extent; it would not be easy to prevent them, even if.

Two ground-based timber harvesting methods have been commonly used for beetle-kill salvage treatments after a bark beetle epidemic in northern Colorado.
A “lop and scatter” method uses a mobilized stroke delimber to delimb and buck trees at the stump, leaving tree tops and limbs on the forest floor, while a whole-tree harvesting method brings the entire tree to the landing where it is Cited by: 6.
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:. Douglas-fir beetles (Dendroctonus pseudotsugae) can kill large-diameter trees (8" diameter or greater).
Douglas-fir beetles have an earlier flight schedule. Adults emerge and find new host material as early as April at lower elevations or after mild winters. Douglas-fir .Non Technical Summary Harvesting of southern pine forests often results in large quantities of slash that can be challenging to manage.
As is true of most aspects of forest operations, there is no one-size-fits-all approach for dealing with slash. In fact, there are several options commonly used in southeastern forests, each with its own advantages and disadvantages.Most of the old-growth stands in the Douglas-fir region Rave developed over years since their origin.
The most common age classes are probably between and years in the Cascade Range. Stands with Douglas-fir trees over l years old are occasionally encountered, however (Hemstrom and Franklin ).
