After an area is harvested it is treated to make regeneration of the site more effective. This treatment is called site preparation. Millson Forestry Service provides many types of site preparation. The type of site prep applied to a site depends on topography, soil type, soil depth, and regeneration method. We also site prep areas that are being converted from farm land back to forested land.
A popular method of site preparation is the power disk trencher. A power disk trencher produces a result similar to a plow on a farm. The disks on the back of the machine create shallow trenches to expose mineral soil while pushing aside any debris. The exposed mineral soil is a suitable micro-site for planting and the reduction in debris reduces competition for light and other necessary resources.
The Bracke is a similar type of site preparation except that this method creates small treated patches instead of furrows. The primary advantage in this type of site preparation is that it is non-continuous, thus lessening the chance of erosion on a susceptible site.
On sites where the productive soil is covered by organic and debris layers, with minimal topography, shear blading can be used. A bulldozer clears strips throughout the block. The operator attempts to remove the debris and organic layers of soil without removing the mineral layer. One advantage of this method is that it can be used in the winter whereas the other two methods can only be utilized when the soil is not frozen.
When harvesting and hauling has been completed there are many branches and other woody debris left on the site. In some cases, these branches and debris (called slash) can occupy over 10% of the area of a block. This area is unavailable for regeneration since insufficient amounts of light are available to plant life underneath the slash. Millson Forestry Service uses various types of equipment to pile this slash to increase the amount of productive area for regeneration. These large piles may also be burned in order to further increase the area available for regeneration.
