Adaptive management of road networks depends on timely data that accurately reflect the impacts of network impacts on ecosystem processes and associated services. In the absence of reliable data, land managers are left with little more than observations and perceptions to support adaptive…

Relationships between land use/cover (LUC) and stream water quality have been well-documented in many environments and at a range of spatial scales. From these analyses, reduced in-stream biological integrity and habitat quality are commonly associated with increasing amounts of anthropogenic…

While numerous scientific publications have used biological data and sometimes decision theory to identify where conservation funds should be invested, studies that examine where money for conservation actually has been spent and how investment patterns have changed through time are scarce. We…

The threat of climate change is a great challenge to sustainable land management (USDA-NRCS, 2010a). Several publications have reported that over the last few decades, rainfall intensities have increased in many parts of the world, including in the United States. Without good, productive soils…

Remote sensing images obtained by remote sensing are a key source of data for studying large-scale geographic areas. From 2013 onwards, a new generation of land remote sensing satellites from USA, China, Brazil, India and Europe will produce in 1year as much data as 5 years of the Landsat-7…

Groundwater is widely used as a source of drinking water in North America. However, it can be contaminated by microbial or chemical agents potentially hazardous to human health. In recent decades, governments have developed better knowledge of groundwater and established measures to protect and…

There is an increasing interest in applying fractal analysis to measure the spatial complexity of remotely sensed images. This study provides an evaluation of the effectiveness of three fractal algorithms (isarithm, triangular prism, and variogram) for characterizing urban landscapes in…

Research conducted in a variety of hardwood regions across the United States has indicated that utilization of small-diameter roundwood is hindered by a lack of markets. Efficient removal of such material could enable silvicultural practices to improve stand conditions and economic return for…

We used data from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) in association with county-level data from the United States Department of Agriculture (USDA) to develop empirical models predicting maize and soybean yield in the Central United States. As part of our analysis…

Private land conservation is becoming a popular policy approach, given the constraints of increasing public protected areas, which include reduced availability of land for purchase, insufficient budgets for acquisition, and escalating management costs of small, isolated reserves. Conservation…

Conservation investment in management of at-risk species can be less costly than a delay-and-repair approach implemented after species receive legal protection. The United States Endangered Species Act candidate species designation represents an opportunity to implement proactive management to…

We examined the utility of nutrient criteria derived solely from total phosphorus (TP) concentrations in streams (regression models and percentile distributions) and evaluated their ecological relevance to diatom and algal biomass responses. We used a variety of statistics to characterize…
