A healthy understory commmunity is a key factor in maintaining the biodiversity of longleaf pine (Pinus palustris) stands, and there appears to be a strong relationship between the occurrence of fire and the condition of the understory vegetauon. Generally, the understory is healthier in burned…

Although the silvicultural use of prescribed fire has been researched for almost 70 years, new advances are still being made. These advances are primarily the result of (1) a better understanding of fire as an ecological process and (2) the use of this knowledge to restore declining ecosystems,…

Detailed airborne measure ments of smoke plumes from seven prescribed burns of forest biomass residues leftover from timber harvests in Washington and Oregon are described. Measurements of particle size distributions in the plumes at 3.3 km downwind of the burns showed a prominent peak in the mass…

Research has developed guides for consistent natural regeneration of longleaf pine by a shelterwood system. Key measures include hardwood control by fire and other means, timely preparatory and seed cuts, seed crop monitoring, seedbed preparation, protection of established seedlings, prompt removal…
