During the summer of 1976 and winter of 1976-77, understory production was measured in 3 old home sites and in 12 other timber strata in the Upper Coastal Plain of South Carolina. These strata differed in stand composition, condition and age. Summer production in old home sites ranged from 496-922 kg per ha,. and winter production from 128-433 kg per ha. Relatively open canopies probably contributed to high yields. Winter yields from known deer food species were substantially greater in old home sites, range 40.1-303.4 kg per ha (X=207). Japanese honeysuckle (Lonceriajaponica) was abundant...

Seasonal prediction models for understory production from simple overstory measurements were developed using regression analysis. During the summer of 1976 and winter of 1976-1977, production of understory vegetation was recorded by species or species groups in timber stands on the Savannah River Plant using a 100% clip method. Overstory density and basal area were also recorded. Sampled timber stands ranged from pine regeneration sites with measurable overstory (stems > 3 cm dbh) to immature sawtimber of pine and upland hardwoods. Quadratic equations using basal area of all stems...

Repellents were tested in 1970 in an effort to control white-tailed deer (Odocoileus virginianusl damage to plantea loblolly pine (Pinus taeda) seedlings on areas converted from mature pine with hardwood understory to large even-aged pine plantations. Test sites represented various site preparation methods that, after planting, were receiving extensive deer damage in Sumter County, Alabama. The most promising chemical deer repellents, according to previous studies, and two non-chemical deterrents (plastic bags and clipped seedlings) were tested In this study, Arasan, Z.I.P., andZAC were...
