Provisional, Forested Ecological Sites in the Northern Appalachians and Their State-and-Transition Models
No full textOn the Ground•The identification of unique areas of vegetative potential across the Northern Appalachians is complicated by a long land-use history of vegetation management.•We introduce provisional ecological sites and associated state-and-transition models for the region, which can be differentiated by latitudinal drivers of: precipitation and temperature; local parent material and resulting soil differences; and landscape position, slope, or aspect.•Identification of ecological sites and associated States or Phases in the Northern Appalachians provides land managers with quantifiable benchmarks for assessing forest compositional shifts due to natural or anthropogenic disturbance

Insights and Approaches for Mapping Soil Organic Carbon as a Dynamic Soil Property
No full textSoil organic C (SOC) content is one of the most dynamic of soil properties. In this study, we examined the effects of land use change on SOC pools for a single soil series and developed a mapping approach to relate SOC dynamics to land use change. Six paired sites, consisting of adjacent agricultural field and forest within a single delineation, were sampled and the SOC pools determined. The average forest SOC pool (157 Mg ha-1) was significantly higher (P \u3c 0.05) than the field pool (103 Mg ha-1), supporting the importance of land use on SOC pools. We propose the development of a SOC phase based on land use to map such differences. Master O and A horizon data should be used to establish SOC phases. Data can be obtained from existing soil surveys, updates, or C accounting activities. Land use classes can be identified with digital imagery and SOC phases can be assigned to all mapping units. Mapping units sampled for C accounting can be resampled to detect patterns and rates of change. This approach provides a robust data set to effectively map and model SOC pools and change across the landscape. © Soil Science Society of America, 5585 Guilford Rd., Madison WI 53711 USA All rights reserved
