Transcript of Patch and Strip Logging

Patch and Strip Logging The patch and strip logging is the same as clear cutting, but much smaller areas are cut. In patch logging, small patches are
cleared in the forest. In Strip logging, each cutter is given a strip
of land to cut. A strip of forest is always left between
the cutting What is Patch and Strip logging Patch and Strip logging involves the clear-cutting of a thin strip of forest that goes along the river, along the slope. Pro's
~1.~ Less of the forest is gone. Only small patches are gone.

~2.~ From the trees that are not gone, their seeds spread to grow more trees

~3.~ There will be less soil erosion

~4.~ It is more difficult to use larger machines, so the soil will not be as crushed as it would normally would by larger machines Pro's + Con's

~1.~ Expensive because it is difficult to use larger machines 1. Strips and patches of proper orientation and width provide side shading or screening that modifies surface and light conditions during the establishment period, and protects the new trees from wind and exposure during juvenile stages of development.
2. Side lighting from recently cut strips and patches often promotes advance regeneration along edges of the bordering uncut areas, and these seedlings develop rapidly when released by overstory removal.
3. Removal of adjacent strips and patches in a progressive series reduces shading over the previous regeneration area, thereby encouraging the continued development of each previously established age class.
4. By using directional felling and confining skidding to uncut parts of a stand, contractors protect the young trees from logging damage.
5. The well-organized arrangement of age classes facilitates subsequent tending and harvesting operations.
6. Environmental conditions inside the patch and strip openings usually favor species with low to intermediate shade-intolerance, increasing the species richness in a stand.
7. The patterns of development within each strip resemble those in even-aged communities. The result may be an enhancement of some nonmarket values, such as early dominance of herbaceous vegetation and a high initial stem density that provides important habitat for some wildlife species.
8. Creating strip and patch openings reduces interception of snow and rain so that more of the precipitation reaches the ground surface within the regeneration areas. Deeper snow could protect seedlings against winter exposure and animal browsing. One of the most popular machines they use is the spider claw. By: Ryan, Chloe, Miranda, Andrew and Meghan. the end
