Free tree seedlings nc8/7/2023 Poor logging practices can be severe and so irreversible that they cause loss in soil productivity and dam age residual trees which may provide a seed source. Loggers must take extreme care to avoid logging with heavy equipment during periods of soil saturation. In Southern pine regeneration, the harvest is much more than just a logging operation. Harvesting and Logging Skip to Harvesting and Logging Trees killed may often be used for firewood, posts or other wood products. TSI may be done manually, mechanically or with herbicides. TSI is often carried out in stands where all hardwoods exceed 4 inches in diameter or in stands where prescribed burning is not recommended, such as in the management of white pine which is not fire resistant. TSI can reduce undesirable seed and sprout sources and eliminates competition when it is used in certain stands. Prior to the final harvest, crews should kill trees of inferior species, poor form or trees infected with insects and disease. It may be necessary, depending on density of weed competition and amount of fuel, to treat with more than one burn.īurning may begin six to eight years prior to the final timber harvest and be repeated at two- to three-year intervals with the final burn done within two years of the harvest. Eastern white pine is thin-barked and will not tolerate prescribed burning. These species have a thick well-insulated bark when over 4 inches in diameter and 20 feet in height. Prescribed burning may be done in loblolly, shortleaf, longleaf, and pond pine stands. Fire is particularly effective in killing small diameter, thin-barked hardwood species such as maple and sweetgum.īurning excess fuel in pine stands by using prescribed burning also reduces the risk of wildfire. Fire applied under proper fuel moisture and weather conditions is a cost-effective method to reduce weed competition. The two most common preharvest treatments which may be used alone or in combination are: The end result of preharvest treatment is to reduce the need for heavy mechanical site preparation after the regeneration cut. This results in a greater rate of early growth and survival of regenerated stands. Preharvest treatments lower the cost of reforestation by reducing competition from cull hardwoods and other weeds.
