The effects of burning cycles and pine basal area levels were assessed on natural pine regeneration and hardwood development in uneven-aged stands of loblolly andshortleafpines (Pinw taeda L. and P. echinata Mill.). The treatments included an unburned control and prescribed winter burrs at 3-, 6-, and 9-yr intervals. Basal area treatments were 9, 14, 18, and 23 m2 ha-’ for the merchantable-pine...

Imazapyr, metsulfuron methyl, imazapyr plus metsulfuron methyl, and hexazinone plus metsulfuron methyl were aerially applied over newly planted and l-year-old loblolly pine seedlings for the control of blackberry (Rubus species), composites (Compositae), sumac (Rhus copallina L.), and trumpet vine [Campsis radicans (L.) Seemann]. The study was installed at three locations with three replication...

Effect of Termination of Long-term Free Air CO2 Enrichment on Physiology and Carbon Allocation in a Loblolly Pine Dominated Forest

Forest operations such as harvesting, thinning, and site preparation can affect the hydrologic behavior of watersheds on poorly drained soils. The influence of these operations conducted on organic soil sites can be more pronounced than on mineral soil sites due to the differences in bulk density and soil moisture relationships that exist between mineral and organic soils. This article reports ...

Changes in aboveground net primary production (ANPP) are relevant to forest management, ecosystem ecology and carbon budget. It is believed that ANPP reaches a maximum young stands then gradually declines as age. Intensive silvicultural treatments such competing vegetation control fertilization have been widely used pine plantations the southern US shown large early growth gains. The effects of...
