Thinning

Thinning may be done to increase the resistance of the stand to environmental stress such as drought, insect infestation, extreme temperature, or wildfire.An early thinning would encourage trees to develop wider crowns, increase trunk diameter and be more stable against threats like snow breakage or windthrow.Epicormic shooting is a risk when thinning is carried out tardily, which can lead to tree branchiness and the presence of knots in the resultant timber harvest, again reducing value.Norway spruce on a suitable site have responded well in terms of growth increment, to late thinnings (after 50 years)[4] whereas other species have not for example slash pine.[8] In agriculture and gardening, thinning is the selective removal of flowers, fruits, shoots, and seedlings or young plants to allow adequate space for the remaining organs/plants to grow efficiently.In large-scale farming, techniques like precision seeding and transplanting can eliminate the need for thinning by starting plants at their optimum spacing.
