Digital mapping of ecological land units using a nationally scalable modeling framework

Ecological site descriptions (ESDs) and associated state-and-transition models (STMs) provide a nationally consistent classification and information system for defining ecological land units for management applications in the United States. Current …

Prioritizing land for investments based on short- and long-term land potential and degradation risk: A strategic approach

The response hierarchy of “Avoid \textgreater reduce \textgreater reverse” is increasingly acknowledged as the best strategy for prioritizing actions designed to address land degradation at hectare to national scales. This hierarchy is based on the …

Applying fingerprint Fourier transformed infrared spectroscopy and chemometrics to assess soil ecosystem disturbance and recovery

The assessment and monitoring of soil disturbance and its effect on soil quality (i.e., ability to support a range of ecosystem services) has been hindered due to the shortcomings of many traditional analytical techniques, including high cost, …

Breaks in MODIS time series portend vegetation change: Verification using long-term data in an arid grassland ecosystem: Verification

\textcopyright 2017 by the Ecological Society of America. Frequency and severity of extreme climatic events are forecast to increase in the 21st century. Predicting how managed ecosystems may respond to climatic extremes is intensified by uncertainty …

Capturing spatial variability of biogeochemical mass exchanges and reaction rates in wetland water and soil through model compartmentalization

\textcopyright 2015 American Society of Civil Engineers. A common phenomenon observed in natural and constructed wetlands is short-circuiting of flow and formation of stagnant zones that are only indirectly connected with the incoming water. …

Hyper-temporal remote sensing for digital soil mapping: Characterizing soil-vegetation response to climatic variability

Indices derived from remotely-sensed imagery are commonly used to predict soil properties with digital soil mapping (DSM) techniques. The use of images from single dates or a small number of dates is most common for DSM; however, selection of the …

Effect of spatial image support in detecting long-term vegetation change from satellite time-series

\textcopyright 2016, Springer Science+Business Media Dordrecht(outside the USA).Context: Arid rangelands have been severely degraded over the past century. Multi-temporal remote sensing techniques are ideally suited to detect significant changes in …

Uncoupling the complexity of forest soil variation: Influence of terrain indices, spectral indices, and spatial variability

Growing concern over climate and management induced changes to soil nutrient status has prompted interest in understanding the spatial distribution of forest soil properties. Recent advancements in remotely sensed geospatial technologies are …

Fate of nitrate in seepage from a restored wetland receiving agricultural tailwater

Constructed and restored wetlands are a common practice to filter agricultural runoff, which often contains high levels of pollutants, including nitrate. Seepage waters from wetlands have potential to contaminate groundwater. This study used soil and …
