Scientists within the Upland Hardwood Ecology and Management Research Work Unit 4157, along with many collaborators and partners, have developed applied methods to assess site productivity for application to forest management and restoration projects within the upland hardwood ecosystem.
Arkansas, as with much of eastern North America, was once covered by extensive virgin forests with many big, old trees. Logging, land clearing, wildfire, and urbanization, among other causes, have long since eliminated most of these big trees. However, a handful can still be found in the woods of Arkansas, and many others "live" on in historical photographs, explorer and survey accounts, and scientific publications.
Scientists within the Upland Hardwood Ecology and Management Research Work Unit 4157, along with many collaborators and partners, are developing effective, utilitarian inventory and monitoring methods.
In a cooperative study using NRCS field data collected from 41 stands throughout the southern Appalachian Mountains of western North Carolina, we evaluated the influence of six common soil and topographic variables on site index of two commercially valuable mesophytic tree species: northern red oak (Quercus rubra) and yellow-poplar (Liriodendron tulipifera).
Forest site productivity in the southern Appalachian Mountains is associated primarily with the availability of soil moisture during the growing season; stands on moist sites tend to produce greater amounts of woody biomass than stands on dry sites. Because the occurrence of many tree species in this region tends to be associated with a characteristic soil moisture regime, we hypothesized that the species composition of a sample plot could be used as the basis for assessing its moisture regime and predicting site productivity.
EFETAC and its sister Center, the Western Wildland Environmental Threat Assessment Center, are collaborating with federal and university partners to develop strategic research components for the National Early Warning System. These new tools help forest and natural resource managers rapidly detect, identify, and respond to unexpected changes in the nation’s forests impacted by insects, diseases, wildfires, extreme weather, or other natural or human-caused events.
The Forest Service's Remote Sensing Applications Center
(RSAC) is in Salt Lake City, Utah, co-located with the agency's Geospatial Service and Technology Center. Guided by national steering committees and field sponsors, RSAC provides national assistance to agency field units in applying the most advanced geospatial technology toward improved monitoring and mapping of natural resources. RSAC's principal goal is to develop and implement less costly ways for the Forest Service to obtain needed forest resource information.
FIA is a USDA Forest Service research work unit which collects, analyzes and reports on data pertaining to our forest land in the southern region. This region includes Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, Puerto Rico, South Carolina, Tennessee, Texas, the US Virgin Islands, and Virginia.
Scientists within the Upland Hardwood Ecology and Management Research Work Unit 4157, along with many collaborators and partners, study how fleshy fruit and hard mast availability varies among forest types and age-classes, seasonally, and over time as forests mature.
We are also developing models and tools for land managers to assess acorn or fruit production capability of forest landscapes under different management scenarios.
The Resources Planning Act (RPA) Assessment reports on the status and trends of the Nation’s renewable resources on all forest and rangelands, as required by the Forest and Rangeland Renewable Resources Planning Act of 1974.
