Topographic Factors Affecting The Tree Species Composition Of Forests In The Upper Piedmont Of Virginia, Rachael C. Brown, Todd S. Fredericksen
Virginia Journal of Science
There are many factors that influence forest species composition and many are linked to topographical features. This study, conducted on the Ferrum College campus in the Upper Piedmont Physiographic Province of Virginia revealed three major forest types associated with topographic factors using cluster analysis and detrended correspondence analysis . The first type of forest occurred mostly on northeastern slopes on toe slope topographic positions and was mainly composed of tulip tree (Liriodendron tulipifera) and red maple (Acer rubrum). The second type of forest was found on shoulder and side slope positions and was composed mostly of …

Insect Pests Of Forests. 2. Tussock Moths And Bag-Shelter Moths, Clee Francis Howard Jenkins
Journal of the Department of Agriculture, Western Australia, Series 4
TWO native caterpillars which sometimes attract attention are the larvae of the tnssock moth and the bag-shelter moth.
Neither insect is a serious forest pest in Western Australia, but the tussock moth sometimes does restricted damage in orchards and home gardens and the bag-shelter caterpillars cause some defoliation of wattles and eucalyptus.
