The influence of the proximity of urbanization and agriculture to stream water quality is often difficult to quantify. The objectives of this study were to (1) compare the influence of far-field land-use, encompassing a watershed drainage area, to a near-field, 200-m buffer on each side of the stream in an attempt to determine on which zone of influence land-use has the largest impact on water quality, and (2) incorporate the EPA's Rapid Habitat Assessment Protocol (Barbour et al., 1999) to characterize the riparian and channel characteristics of a stream that influence water quality, which can improve New York State's monitoring protocols. Impacts were assessed through biological, chemical, and physical-habitat...
A new avian richness evaluation method (AREM) was developed and tested for assessing lowland wetland and riparian habitats of the Colorado Plateau. AREM rapidly scores habitats for avian richness from simple observations of habitat characteristics. AREM's predictions were compared with original field data from 76 sites on the Colorado Plateau during the breeding season. Species predictions and detections were highly indicative of the breeding avifauna in regional wetlands studied. AREM has implications for use in mitigation calculations, detection of impaired wetland quality, selection of appropriate indicator species, targeting habitat enhancements, wildlife-based classification of wetland habitats, and assisting...
