A Prescription for Old-Growth-Like Characteristics in Southern Pines
نویسنده
چکیده
Recent interest in adding old-growth reserves conflicts with a projected increase in the demand for forest commodities. However, managing for old-grorvthlike characteristics may permit timber production from stands designed to be similar to primeval forests. A silvicultural strategy based on presettlement forest conditions is being tested on 120 ac of mature loblolly (Pinus taeda) and shortleaf (Pinus echinata) pine on the Crossett Experimental Forest in Arkansas. Reference conditions from historical photographs, surveyor notes, old explorer journals, early research papers, and technical reports guided the prescription's design. A combination of harvesting, prescribed burns, and competition control should gradually produce structure similar to pine-dominated presettlement forests. Timber yield and natural attributes will be monitored and compared to traditional silvicultural practices to develop flexible prescriptions that can be modified later, if appropriate.

Silvicultural Considerations in Managing Southern Pine Stands in the Context of Southern Pine Beetle
Roughly 30 percent of the 200 million acres of forest land in the South supports stands dominated by southern pines. These are among the most productive forests in the nation. Adapted to disturbance, southern pines are relatively easy to manage with even-aged methods such as clearcutting and planting, or the seed tree and shelterwood methods with natural regeneration. In addition, most species ...

A collection of subfossil wood of Pinus sylvestris (Scots pine) was exposed to X-ray densitometry. The collection of 64 samples from the southern boreal forest zone was dendrochronologically cross-dated to A.D. 673-1788. Growth characteristics were determined by performing density profiles including the following parameters: minimum density, earlywood and latewood boundary density, maximum dens...

Indirect genetic selection for early growth and disease resistance of southern pines has proven remarkably successful over the past several decades. However, several benefits could be derived for southern pine breeding programs by incorporating ideotypes, conceptual models which explicitly describe plant phenotypic characteristics that are hypothesized to produce greater yield. The potential be...
