C-Lines of Stocking for Southern Bottomland Hardwoods: A Guide to IdentifyingInsufficient Stocking

摘要

A B-line on a stocking chart represents suggested residual stocking afterthinning, or minimum full stocking. A stand at the C-line on a stocking chart will achieve the B-line after a period of growth usually specified as 10 years. Four C-lines that reflect insufficient stocking of southern bottomland hardwoods are presented. These C-line represent 10, 15, 20, and 25 years to reach B-line stocking. Alternative C-lines may be used to determine different silvicultural opportunities--the C-line based on 10 years may be used to identify stands that do not require intervention in the near future; a C-line based on 20 years may be used to identify stands requiring regeneration.
