Effect of preharvest understory treatment and group opening size on four-year survival of advance reproduction in the Boston Mountains of ArkansasThis article is part of a larger document. View the larger document here.
The purpose of this study was to examine survival of regeneration in small openings. Six forest stands were located in 1990 and three understory treatments were applied to each in early 1991. In each stand, six sizes of openings were created in 1992 ranging in size from 0.025 ac to 0.50 ac. Understory treatments consisted of: 1) no control of competing regeneration, 2) mechanical control of competing regeneration (cut stems), and 3) chemical control of competing regeneration (cut stems sprayed with herbicide). Only northern red oak appeared to exhibit a response to treatments with increased survival as intensity of understory control increased and as opening size decreased. We attribute these results to the wide fluctuation in seedling populations and the short time interval between opening creation and post-treatment measurement.
