Deer and Cattle Diets on Heavily Grazed Pine-bluestem Range
We studied dietary overlap between captive white-tailed deer (n = 3) (Odocotleus tir@nlanus) and cattle (n = 4) for 3 years on 2 rotationally burned, 54-ha longleaf pine (Pinus paZustris)-bluestem (Andropogon spp.) pastures in central Louisiana. A third of each pasture was burned each year in late February. One pasture was grazed heavily (61-77% herbage use) yearlong; the other was grazed heavi...
متن کاملThe Longleaf Pine Ecosystem
INTRODUCTION Of the southern pines, many consider longleaf pine (Pinus palustris Mill.) the most valuable in terms of wood-product quality, aesthetics, and resistance to fire, insects, and disease. Longleaf pine ecosystems once occupied more than 90 million acres of the Lower Coastal Plain of the Southeastern United States from southern Virginia to central Florida and west to eastern Texas (Fro...
متن کاملTop Grafting Longleaf x Slash Pine F1 Hybrids on Mature Longleaf and Slash Pine Interstocks
-Top grafting is used to accelerate the breeding cycle of loblolly pine (Pinus taeda L). Scions, collected from seedlings as young as 1 year from seed, are grafted onto mature interstocks of the same or a related species. Male and female strobili production often begins 1 or 2 years after grafting, thus potentially decreasing the generation time by several years over conventional accelerated br...
متن کاملInfluence of supplementation method on forage use and grazing behavior by beef cattle grazing bluestem range.
Two 25-d trials (late summer and early winter) were conducted to determine the influence of supplementation method on forage use and grazing behavior. Fifteen ruminally and 12 esophageally fistulated steers (316 and 400 kg, respectively) were blocked by weight and assigned randomly to one of three treatments: 1) self-feeding supplement (via Calan gates) with salt as a limiting agent; 2) daily h...
متن کاملLongleaf Pine Seedling Production
Longleaf pine is a highly desirable species, resisting fire, insects and pathogens, and produces quality solid-wood products, but regeneration of the species has been difficult. Natural regeneration is feasible only on a small portion of the area considered to be longleaf pine type. Therefore, artificial regeneration must become a reliable means of regenerating the species if restoration of the...
