Forest Ecosystem Restoration and Management
New and improved tools and technology are needed to successfully restore and manage ecosystems in the South, where population growth and demographic shifts are accelerating changes to forest ecosystems. Forest Ecosystem Restoration and Management will provide landowners with the awareness and ability to produce a wider array of economic, ecologic, and social benefits.
•Identifying and mapping the chromosomes of trees using genetic markers and genes is a part of the ongoing multi-agency National Science Foundation Plant Genome Project. With its relatively small genome and 19 pairs of chromosomes, poplar has been considered a model species for forest tree genetics and genome research. (more...)
•Conventional methods for determining forest site quality that use tree age and height relationships are laborious to apply and often provide inaccurate estimates when used in upland oak forests. Alternative techniques based on tree species composition are well suited for forest management planning and are easily combined with routine stand examination inventories. (more...)
•SRS researchers are evaluating silvicultural treatments currently used by the Daniel Boone National Forest, KY in relation to impending infestations by gypsy moth and the related disease complex, oak decline. (more...)
•Studies of Neotropical migratory birds (birds that migrate between the United States and Central and South America) have found declines in both distribution and overall population numbers in Southeast, where they have been tied to habitat fragmentation in breeding grounds and to deforestation of the over-wintering areas. (more...)
•Cryphonectria parasitica is the fungal plant pathogen that causes chestnut blight. The introduction of C. parasitica from Asia into North America in the early 1900s resulted in the death of billions of American chestnut trees in what is still often referred to as one of the worst ecological disasters in U.S. history. (more...)
•Upland hardwood researchers based in the Cumberland Plateau region are participating in three large-scale studies on the effects of forest management on wildlife, designed to: (1) examine how habitats change after disturbances; (2) determine how communities of birds, mammals, reptiles, and amphibians respond to small localized changes in temperature and moisture; (3) determine the effects of forest disturbance on food available to wildlife and diet choices; (4) determine effects of forest disturbance on amphibians that breed in ephemeral ponds; and (5) examine how communities of birds, mammals, reptiles, and amphibians change over time in response to changes in the structure of their habitats. (more...)
•Despite the high number of endangered and sensitive bats in the Southeast, few studies of forest bat habitat use have been conducted in the region. To meet habitat requirements for bats, forest managers need information on the most important factors determining bat habitat use. (more...)
•A SRS study conducted at Fort Benning, GA, is examining the effects of midstory reduction efforts on the health of longleaf pine forests. Early results suggest that stand thinning by mechanical shredding of woody plants is an effective way to rapidly alter forest structure. (more...)
•The oak forests of the Ozark Highlands, one of the region’s greatest and most highly treasured resources, are not regenerating themselves. Oaks are being replaced by more shade-tolerant, less desirable species. Regenerating oak species is particularly complex because the process is affected by a broad set of factors. (more...)
•Forests of the Interior Highlands of Arkansas, Oklahoma, and Missouri are being affected by oak decline and an unprecedented outbreak of a native beetle called the red oak borer. The SRS unit in Arkansas has been at the forefront in detecting, monitoring, and resolving this serious forest health event, as shown by the recent publication of three papers that summarize findings to date. (more...)
•As part of a study of forest management treatments started on the Ouachita National Forest in 1991, SRS scientists monitored small mammal populations in stands where four regeneration treatments were applied?single-tree selection, group selection, shelterwood, and clear-cutting?and compared these to small mammal populations in unharvested controls. (more...)
•A better understanding of the interactions between trees and forest soils is necessary to effectively manage and enhance forests at the landscape scale. Two recent research products provide important new insights into how trees affect soils and vice versa. (more...)
•Across the Southeast, land managers are challenged to restore longleaf pine forests to support red-cockaded woodpeckers and associated species of concern, while retaining critical habitat features, including mature trees. (more...)
•The demand for longleaf pine seedlings continues to increase, but tree nurseries have problems producing uniform high quality seedlings in the large numbers needed. As a result, container longleaf pine planting stock varies widely in both production quality and size; widespread planting of variable quality longleaf planting stock has led to many sapling longleaf trees being blown down by wind storms (windthrow). (more...)
•Habitat for cavity-nesting wildlife such as the endangered red-cockaded woodpecker is closely tied to the availability of standing dead trees (snags). Large snags are particularly important because they provide possible habitat for both large and small cavity excavators. (more...)
•SRS scientists and cooperators have been investigating the ecology, status, and management of the Louisiana pine snake (Pituophis ruthveni), one of the rarest vertebrates in the United States, for more than a decade. (more...)
•After centuries of forestry, the simple aboveground growth of trees is now reasonably easy to predict. Today’s researchers and managers, operating in a time of changing climate and forest management practices, need more information about what happens below ground to accurately predict growth. (more...)
•Long-term studies of the effects of prescribed fire in longleaf pine stands have been conducted in central Louisiana on the Palustris Experimental Forest and Kisatchie National Forest for over 80 years. Study plots include longleaf pine forests that range in size from seedlings to large poles. (more...)
•The southern pine beetle is the most destructive insect pest of pines in the Southeastern United States. Individual pine trees that discharge large quantities of oleoresin (resin) when wounded are considered to be most resistant to attack by this aggressive bark beetle. (more...)
