The British Columbia Forest Service (BCFS) is in charge of managing provincial woodlands.
Among its goals is make sure these forests are handled because productively as you possibly can through a province-wide silviculture system.
In the same way farmers practise the art and science of agriculture to enhance the efficiency of food plants, foresters practice the art and technology of growing woods – or silviculture – to boost the productivity of tree crops.
Silviculture in B.C. requires many different activities including:
Vegetation administration is, of the many silviculture activities, often the the very least comprehended because of the average man or woman. This pamphlet explains why and exactly how foresters practise plant life management in B.C.
Conifers such Douglas-fir, hemlock, spruce, pine, cedar and fir are trees of large commercial price. Like farm or yard crops, these trees need big levels of light, nutritional elements and liquid to cultivate well. However in the early phases of growth, numerous less important trees and a lot of brush types supply powerful competitors of these crucial components. Their growth needs to be managed.
The goal of vegetation administration, after that, should advertise the development of essential crop trees by delaying the rise of contending brush and woods of small commercial value.
The BCFS is providing plant life administration high-priority on one or more million hectares of productive woodland land currently ruled by non-crop development. Further, the BCFS wants this one one-fourth of this around 200 000 hectares harvested every year would go back to clean unless appropriate action is taken.
If woodland supervisors don’t exercise plant life administration when you look at the framework of overall silvicultural attempts, the ensuing lumber loss will have really serious consequences for future years economy of B.C.

You can find five primary options for managing the growth of brush and trees of reduced commercial price:
Handbook techniques make use of hand-held cutting tools eg sequence saws, brush axes or girdling tools (used to eliminate bark from stems). One advantage is they can be utilized selectively to deal with specific woods and brush. However, manual methods tend to be labor intensive and as a consequence, pricey. Often, they truly are efficient for a short while because slashed woods and plants usually resprout and may require retreatments. One of the greatest drawbacks of hand-held cutting resources may be the risky of damage from sharp blades.
Mechanical techniques utilize heavy gear such crawler tractors with attachments for mowing, raking, crushing and chipping. Mechanical methods can help clear a big location in a short time however they are usually limited to planning sites for growing. They generally can compact the soil or cause erosion. They seldom eliminate plant roots which resprout.
Burning up practices are widely used in B.C. to reduce slash and debris ensuing…
