Sawtooth Oak Planting Trials with Site Preparation

Data are presented on the survival and growth response of planted 1-0 sawtooth oak seedlings to 4 site preparation treatments on loamy and sandy soils following clearcutting of the residual forest stands. The 4 site treatments were: (1) control, (2) burn, (3) chopping with a Marden chopper, and (4) KG blading followed by disking. In early April 1975, 12 sawtooth oaks were planted in each treatment plot. In October 1980, 6 growing seasons after planting, the average tree survival dropped from 76% in 1978 to 68% on the sandy soil, but remained at 84% on the loamy soil Average tree height was...

Forage Yield Increased By Clearcutting And Site Preparation

Total forage yield (TFY) on a pine-hardwood forest site in east Texas was sampled before and I growing season after clearcutting (1972 and 1973), also I and 3 growing seasons after planting site preparation by burning, choping, or KG blading (1974 and 1976). Total forage yield was only 359 kg/ ha in the uncut forest, but 2217 kg/ ha after clearcutting. On control plots (no site preparation), TFY peaked in the first growing season after clearcutting with 2917 kg/ ha, but by 1976 decreased to 1983 kg/ ha. On burned plots, TFY peaked the first growing season after burning (3540 kg/ ha) and...

Fruiting Of Browse Plants Affected By Pine Site Preparation In East Texas

Pine planting sites prepared by burning yielded 120 kg/ha of browse fruits thethird growing season after site treatment. Control plots yielded 74, KG-bladed plots 57,and chopped plots 41 kg/ha, Blackberries, American beautyberry, sumac, Sebastian bush,muscadine grape, blueberries, and southern wax-myrtle were the principal species. Mostfruit was available in summer and fall, but some persisted through winter and spring.Fruit production was related to the number and average height of the fruiting browse species.

Browse Quality Affected by Pine Site Preparation in East Texas

An east Texas pine-hardwood forest was clearcut in 1972, and selected sites were burned, chopped, KG bladed, or left untreated in the winter of 1973-1974. Crude protein, calcium, and phosphorus content in leaves and twigs of four browse species were measured in April, September, and November after site preparation. Among site treatments, burning usually resulted in highest nutrient contents, followed by chopping, control, and KG blading. The levels of crude protein and phosphorus in all browse were highest in April, but declined in deciduous plants as the seasons advanced; evergreens held...
