Sustaining the Productivity of Planted Forests
Conversion of natural forests to plantations, particularly in the tropics, has drawn global attention and concern. Moreover, plantation forestry is on the rise, especially in tropical and sub-tropical regions where growth rates are rapid. Even in the United States where even-age silviculture is being de-emphasized on public land (only about 15Oh of all plantings in recent years), the area in ne...
متن کاملA tree-growth model to optimize silviculture
In this paper, we present the description of a simplified model of the dynamic of a mono-specific even-aged forest. The model studied is a tree-growth model based on a system of two ordinary differential equations concerning the tree basal area and the number of trees. The analytical study of this model permits us to predict the behavior of the system solutions. We are trying to highlight the i...
متن کاملObject-Based Classification of UltraCamD Imagery for Identification of Tree Species in the Mixed Planted Forest
This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...
متن کاملChainsaws, Canebrakes, and Cotton Fields: Sober Thoughts on Silviculture for Songbirds in Bottomland Forests
Forested wetlands of the Mississippi Alluvial Valley (MAV) are the most productive of birds, including neotropical migratory birds, of all land uses there. Forest land uses are difficult to maintain in economic competition with annual crops. We compare perspectives of a bird biologist, a wildlife manager, a production forester, and an economic pragmatist to the issue: How can we manage bottomla...
