“…Most erosion resulting from forestry is from poorly constructed and maintained roads, especially if traffic moves perpendicular to drainage ditches or natural contours of the land (Askew and Williams 1984;Yoho 1980). Sandy uplands soils are susceptible to gully erosion (Figure 15), which channels water movement and carries the sandy soils into lower-lying areas (J. Murian, pers.…”

Longleaf pine woodlands on military installations support multiple uses, including the Department of Defense (DoD) training and testing mission; threatened, endangered, and sensitive species (TES) conservation; and forest commodities (e.g., timber, pine straw) production. This report documents strategies to manage TES and their habitats on a plant community basis, using methods that apply to multiple species, and using methods that apply across the southeastern region of the United States. This report combines the pine flatwoods and sandhills communities because they have several features that link them. Ecological descriptions are provided for each community, along with available information about community occurrences on DoD installations throughout the southeast region. Known occurrences of plant and animal TES associated with longleaf pine woodlands on DoD lands are also reported. Known and potential impacts to the integrity of longleaf pine woodlands as TES habitat, and to associated species are reported. Impacts may be related to habitat fragmentation, or changes in community composition, structure and function due to altered fire regime, hydrologic patterns, soil stability and structure, groundcover integrity, or the invasion of exotic or pest species. Management recommendations are made within an ecosystembased, adaptive management context.

“…Most erosion from forestry results from poorly constructed and maintained roads, especially if traffic moves perpendicular to drainage ditches or natural contours of the land (Yoho 1980;Askew and Williams 1984). It is possible that similar effects occur as a result of military vehicle movement, since careful road placement and maintenance are not the highest prioirities in battlefield simulation exercises.…”

Military training and testing mission requirements make up the highest priority land uses on Department of Defense (DoD) lands. The U.S. Armed Forces require realistic, relatively natural, and expansive areas for adequate training. Training activities can lead to degradation of sensitive natural resources, but they also produce benefits. An ecosystem-based approach to managing threatened, endangered, and sensitive species (TES) and other natural resources provides DoD with an efficient, effective, and flexible framework for evaluating impacts, assessing natural resources, and generating management solutions to potential conflicts between training and TES conservation. Any increase in understanding about the habitat requirements of listed TES species will assist training and natural resource personnel in complying with the Endangered Species Act while avoiding restrictions on the military mission. This report is to be used by DoD natural resource policymakers, installation land managers, and the natural resource research community, in conjunction with associated documents produced by this SERDP work unit to (1) develop ecosystem-based approaches to describe natural communities and TES habitat in relation to military activities, (2) evaluate military-related effects on those communities, (3) develop community-based strategies for supporting both military land use and TES habitat management, and (4) develop management solutions for military impacts to natural communities when management for TES habitat is a priority for a particular location.

“…The ecosystem is altered but continues to meet jurisdictional wetland criteria; t therefore, the practice is exempt from permit requirements under the Clean Water Act [29]. Some lands converted to pine plantations produce remarkably high water quality [30]. On mineral soils, the major problem appears to arise from increased sediment in ditches soon after construction and from surface material added to logging roads [30,31].…”

Wetlands have been intricately linked with humankind throughout the ages. Evidence of rice culture dates to the earliest age of humans, long before the era of historical records. Drain-field and raised-field agriculture occurred in wetlands throughout large areas of Mesoamerica before Hispanic exploration of the region. About 40% of the world's population uses rice as a major staple; rice culture currently occupies about 15% of the world's wetland area. Wetlands are valued for high biological productivity; as filters, sinks, and transformers for sediments, nutrients, and pollutants; and as buffers between aquatic systems and human activities on upland areas. Because of their varied ecological functions, wetlands are of interest to ecotoxicologists as potential sites for detoxifying pollutants. Estimates are that wetlands occupy about 3 to 6% of the world's land area. Attempts to define, delineate, monitor, and regulate the use of wetlands in the United States have proven to be extremely complex. Considerable progress has been made in classifying and monitoring changes in wetland areas on a nationwide basis, but less success has been achieved in defining and delineating wetlands. The United States experience should be a useful model for developing countries to study as they attempt to deal with wetland management and protection. As long as the world's population continues to grow at exponential rates, it seems highly probable that pressure to use wetlands to meet society's demands will increase. Consequently, opportunities to set aside reserves will decrease, and the role that wetlands play in maintaining quality of life will depend more and more on our collective ability to develop and promote compatible uses on wetlands.
