Even-Aged vs. Uneven-Aged Silviculture: Implications for Multifunctional Management of Southern Pine Ecosystems
We evaluated evenand uneven-aged silvicultural options for slash pine (Pinus elliottii Engelm.) using empirical data and the Forest Vegetation Simulator (FVS) model. Data were collected from a mature unthinned slash pine plantation in a flatwoods site in Florida, and used to simulate six scenarios of evenand uneven-aged silvicultural regimes applied to slash pine stands, including a no-action o...
متن کاملUneven - aged Management for Longleaf Pine : Freedom to Choose
Longleaf pine once was present on 90 million acres of the southern landscape, ranging from coastal Virginia to east Texas and from central Florida to the mountains of Alabama. On nearly two-thirds of that area, longleaf pine grew in nearly pure (single-species) stands maintained by frequent, low-intensity surface fires of both natural and human origin. The remaining one-third of that area was s...
متن کاملOptimal Management of Naturally Regenerating Uneven-aged Forests
A shift from even-aged forest management to uneven-aged management practices leads to a problem rather different from the existing straightforward practice that follows a rotation cycle of artificial regeneration, thinning of inferior trees and a clearcut. A lack of realistic models and methods suggesting how to manage uneven-aged stands in a way that is economically viable and ecologically sus...
متن کاملInstitutional mapping of Oregon coastal watershed management options
Institutional mapping is a technique that builds on the logic of Geographic Information Systems (GIS). In GIS, coverages placed over a base map show spatial relations. Social institutions are more difficult to ‘‘map’’ physically. Institutional mapping uses three social coverages—scale, power, and capital. Four sets of institutions affecting watershed management—salmon restoration, water quality...
