- Forest Stand Development Patterns in the Southern Appalachians. Copenheaver, Carolyn A.; Matthews, Jeff M.; Showalter, Julia M.; Auch, Walter E. // Northeastern Naturalist;2006, Vol. 13 Issue 4, p477
Composition of southern Appalachian forests are influenced by disturbance and topography. This study examined six stands in southwestern Virginia. Within each stand, a 0.3-ha plot was established, and all trees and saplings were measured and aged. Burned stands had lower densities of saplings...
- Spatial pattern of trees influences species productivity in a mature oak—pineÂ mixed forest. Ngo Bieng, Marie Ange; Perot, Thomas; de Coligny, François; Goreaud, François // European Journal of Forest Research;Nov2013, Vol. 132 Issue 5/6, p841
Spatial pattern has a key role in the interactions between species in plant communities. These interactions influence ecological processes involved in the species dynamics: growth, regeneration and mortality. In this study, we investigated the effect of spatial pattern on productivity in mature...
- A WaLK IN THE WOODS. Cowan, Mary Morton // Appleseeds;Oct2003, Vol. 6 Issue 2, p30
The author lives in the northeastern United States. He identifies a few common trees of the northeastern woods. Beech trees of all ages have smooth, light-gray bark. One can recognize the sugar maple by the deep U-shaped notches on its large leaves. Eastern white pines are the tallest evergreen...

- America's Forests. Stone, Lynn M. // America's Landscape;2003, p18
The article describes the forests of the United States. Most U.S. mountains are covered with dense forests. The woods of the northern U.S. are largely covered with forests of spruce and pine. In the south, the nation has a true subtropical forest.

- Conflicting views at the gene pool. // Canadian Geographic;Dec90/Jan91, Vol. 110 Issue 6, p12
Discusses the debate that centers around the preservation of the older stand of white pines in Ontario. Why the trees have survived; Differing views of how to preserve them; Size of trees.
- Changes to preindustrial forest tree composition in central and northeastern Ontario, Canada. Pinto, F.; Romaniuk, S.; Ferguson, M. // Canadian Journal of Forest Research;Jul2008, Vol. 38 Issue 7, p1842
Preindustrial forest composition for >180Â 000 km2 throughout central and northeastern Ontario was recreated from Ontario Crown land survey notes (1816â€“1955) and compared with existing forest composition derived from current Forest Resource Inventories (1998â€“2009) in each of Site...
