Fusiform rust, is the most damaging disease of slash and loblolly pines throughout the southeastern United States. This disease causes stem, branch and trunk cankers (galls) to form on infected trees.
- Critical Force for Buckling Tree Stems
-
Tree strength and stiffness can resist significant forces and not fail. A large proportion of this strength lies with the thickness (diameter) of the stem. Stem buckling occurs when an exerted force begins and continues to bend the stem beyond recovery.

- Forested Wetlands: Regulations Affecting Management
-
Acknowledging the importance of forested wetland ecosystems, all levels of government have developed guidelines and regulations for silvicultural activities in wetlands.
- Forest Pest Control Perspective
-
Many of the pest problems in forests are present because of past forest practices. Exploitive harvesting has left nonmerchantable trees, brush, and nonstocked lands covered with weeds that prevent regeneration of desired species. Present forest managers are now adopting management methods that minimize the creation of new pest problems.
- Constructing Wetlands During Reclamation to Improve Wildlife Habitat

- Center for Biodiversity and Conservation
-
Forest fragmentation from urban sprawl is a site-level phenomenon; however, it affects conservation of biodiversity at landscape and regional scales. Impediments to conservation occur when crossing jurisdictional and agency (local, state, and federal) boundaries.
- Biology and host associations of redbay ambrosia beetle (Coleoptera: Curculionidae: Scolytinae), exotic vector of laurel wilt killing redbay trees
-
The redbay ambrosia beetle and its fungal symbiont, Rafaelea sp., are new introductions to the southeastern United States responsible for the wilt of mature redbay, Persea borbonia (L) Spreng., trees. In 2006 and 2007, we investigated the seasonal flight activity of X. glubratus, its host associations, and population levels at eight locations in South Carolina and Georgia where infestations ranged from very recent to at least several years old.

- Gypsy Moth Damage
-
The gypsy moth is the most important defoliating insect of hardwood trees in the Eastern United States. Since the turn of the century, millions of dollars have been spent in efforts to control or eliminate gypsy moth populations and to retard natural and artificial spread. In the early decades of this century, outbreaks occurred only in New England; today defoliation by the gypsy moth is far more severe and widespread.
- Timber and the Economy of Alabama
-
Alabama's first residents called themselves "the thicket clearers," or "AlaBamas." The forest, once viewed as an impediment to agriculture, is now recognized as the backbone of the state economy. Trees from the forest feed an industry that directly employs more than 49,000 workers, indirectly provides employment for thousands more, and is the leading contributor to the gross state product.

- How to Save Dutch Elm Diseased Trees By Pruning
-
Dutch elm disease (DED), caused by the fungus, Ceratocystis ulmi, is the most devastating shade tree disease in the United States. Healthy elms can become diseased by 1) elm bark beetles that carry the fungus from elm to elm, or 2) through root grafting with already infected trees. Along with wilt symptoms, streaking (sapwood discoloration), a characteristic internal symptom of the disease, progresses rapidly down from limbs inoculated by bark beetles (Allison 1978).
