AgForest of Georgia, owned by Chris Polk of Greensboro, Georgia, has been hired by a landowner in Jasper County to thin 124 acres. Forest Thinning is the calculated removal of timber from an existing stand with predetermined objectives in mind. Thinning is done to promote the growth and development throughout the life of the timber on a tract. It also protects from the infestation of pine beetles and other insects that can be harmful to timber and cause it to die.
Two different Thinnings are required for efficient growth and the best value for timber. The first thinning can be done on a planted tract or on a natural tract of wood. This first thinning only a few selected rows are harvested, but certain trees from other rows are selected as well. The trees are selected by the size of the timber on the tract. Trees need to have a diameter of at least six inches and a live crown of 35 or lower which typically occurs around 13 to 15 years of age. The trees that are removed on the remaining rows are the genetically weaker trees that may be forked, crooked, or have signs of disease.
Chris Polk of Greensboro, Georgia also performs a second thinning 5-7 years after the 1st thinning, or when a basal area of 120 is reached. During a 2nd thinning, the basal area will be cut down to about 50-70 trees. The remaining trees will grow into large saw timber or pine poles. 1st and 2nd thinning are done to insure that the land owner is giving the timber on the property the best conditions to mature. These thinnings also improve habitat for wildlife.
Chris Polk of Greensboro believes without thinning timber growth will become stagnant and the value of the timber will be diminished. AgForest of Georgia uses the most up to date harvesting techniques in order to harvest the timber efficiently with minimal disturbance to the property and the property owners.
