Thinning Jack Pine in the Nebraska Sand Hills
Abstract:Two remeasurements of thinning plots in the Nebraska National Forest jack pine plantations of 1903 indicate that the heavily thinned stand with 696 trees per acre has made a gain in volume of 58 per cent compared with the unthinned stand with 2,098 trees per acre. The moderately thinned stand with 1,480 trees has made a 41 per cent gain, and the lightly thinned with 896 trees a 31 per cent gain. Both the accelerated growth and the stronger wood structure, as results of thinning, suggest the advantage of heavy thinnings to concentrate the growth on a smaller number of individual trees which will have a more nearly sufficient supply of moisture.
