Dogwood Anthracnose and its Spread in the South

In the 15 years since it was first reported in the United States, dogwood anthracnose (caused by Discula destructive sp. nov.) has spread rapidly and caused serious losses among flowering dogwoods (Cornus florida L.), particularly in the South. Infection begins in leaves and spreads to twigs and branches, which die back. Main-stem infections cause cankers, which kill the trees. In the South, infection is most likely at higher elevations and on moist to wet sites. Shade increases risk of infection and mortality. High-value trees can be protected by mulching, pruning, and watering during droughts, and applying a fungicide.

Dogwoods for American Gardens

Seventeen species of dogwood are native to the United States, with about 50 throughout the northern hemisphere of the world. The familiar species we call “flowering dogwood,” Cornus florida, is related to many others. This publication discusses those of ornamental value.

Growing and Maintaining Healthy Dogwoods

The natural range of dogwoods extends from Maine to the Gulf of Mexico. The trees color cities and countrysides white with dazzling displays in the early spring. Although they are most spectacular in spring, part of the attraction of dogwoods lies in their year-round beauty. They are truly a four-season plant, displaying rich green luster in the summer followed by deep red leaves in the fall. Bright red clusters of seeds decorate the tree in the winter months.

Identifying Oak Trees Native to Tennessee

Twenty distinct species of oak are native to Tennessee. Correctly identifying oaks can sometimes be challenging, even for well-trained foresters and botanists. This publication on identifying oak trees will introduce you to brief recognizable features or “BRFs.” BRFs (pronounced briefs) are easy to remember and will help you distinguish between different oak species. Using BRFs, this publication summarizes key features that will allow speedy and accurate identifi cation of Tennessee oaks.

Managing Oak Decline

Oak decline is a slow-acting disease complex that involves the interaction of predisposing factors such as climate, site quality and advancing tree age.

Managing for Hardwood

Forestry is one of the top three industries in North Carolina, where approximately 62 percent of the state's 32.2 million acres are forested. Approximately 67 percent of the forest land consists of hardwood or mixed pine-hardwood. Benefits from hardwood forests include watershed protection, wildlife, timber, recreation, and aesthetics. Increased demand for hardwood, due to tighter controls on federal lands and the hardwood exports, has increased the need for management of existing hardwood stands.

Oak Shelterwood: A Technique to Improve Oak Regeneration

The oak shelterwood method has been developed to enhance the regeneration potential of oaks growing on intermediate and high-quality sites. The method involves a well-timed mid-story removal to improve the number and vigor of oak advance regeneration and a subsequent overstory removal to facilitate regeneration of the stand.

Southern Hardwood Management

Hardwood forests represent an extremely diverse and valuable assemblage of species. To some, hardwood management is a confusing and difficult concept to grasp. Unfortunately, past harvests in many hardwood stands removed only the best quality stems of a few select species, leaving poor quality often less desirable species in the wake. Because of past practices in many hardwood stands, some may not believe that hardwood forests can be properly managed for pulp, lumber, water quality, aesthetics, wildlife habitat, and a host of other amenities. We hope this publication will serve to expand the private forest landowners' horizon to the possibilities of hardwood management.

Treatments for Improving Degraded Hardwood Stands

Popular sentiment is that the small trees in the lower canopy when released will become the large trees of tomorrow. The largest and best trees are repeatedly harvested leaving the smaller, inferior trees to perpetuate the next stand. In reality, the trees being released are probably of similar age as those being cut. These released trees are incapable of continued growth with their small, spindly crowns. The consequence of removing only highly valued trees with each harvest is a hardwood resource with ever lower levels of economically valuable trees.

Yellow-Poplar: Characteristics and Management

Yellow-poplar is one of the top commercial hardwood species in the United States because of its availability, rapid growth, large size, excellent form, early natural pruning, and the good working quality of the wood.
