Changes in Stand Structure Following Prescribed Burning in a Loblolly-Shortleaf Pine Forest
Abstract:Prescribed burnings were applied as backfires in the summer and in the winter in the hilly upper Coastal Plain region of Alabama. The burnings were repeated after three years. For pines of 4 inches d.b.h. and up, summer burning on ridges caused significant losses (relative to the control plots) only in the 4-, 5-, 6-inch class and only during the first two years after the initial burning. Summer burning on slopes caused continuous losses in the 4-, 5-, 6- inch class throughout the 9-year measurement period, and caused losses in the 7-, 8-, 9-inch class during the two years following the second burning. The losses in the 7-, 8-, 9-inch class were attributed, however, to lack of ingrowth following damage to the 4-, 5-, 6-inch class by the initial burning. Winter burning caused significant losses only in the 4-, 5-, 6-inch class and only on slopes, but these losses were continuous for the 9-year measurement period.
