Flooding Frequency Alters Vegetation in Isolated Wetlands
Kim H. Haag, Terrie M. Lee
2006, Fact Sheet 2006-3117
Many isolated wetlands in central Florida occur as small, shallow depressions scattered throughout the karst topography of the region. In these wetlands, the water table approaches land surface seasonally, and water levels and flooding frequency are largely determined by differences between precipitation and evapotranspiration. Because much of the region is...
Strength in Numbers: Describing the Flooded Area of Isolated Wetlands
Terrie M. Lee, Kim H. Haag
2006, Fact Sheet 2006-3118
Thousands of isolated, freshwater wetlands are scattered across the karst1 landscape of central Florida. Most are small (less than 15 acres), shallow, marsh and cypress wetlands that flood and dry seasonally. Wetland health is threatened when wetland flooding patterns are altered either by human activities, such as land-use change and...

Effects of Streambank Fencing of Near-Stream Pasture Land on a Small Watershed in Lancaster County, Pennsylvania
Daniel G. Galeone, Dennis J. Low, Robin A. Brightbill
2006, Fact Sheet 2006-3112
This study indicated that a small buffer width along a stream in pasture land can have a positive influence on surface-water quality, benthic macroinvertebrates, and near-stream shallow ground-water quality. Overland runoff processes that move suspended sediment to the stream were controlled (or reduced) to some extent by the vegetative buffer...
Data Delivery and Mapping Over the Web: National Water-Quality Assessment Data Warehouse
Richard W. Bell, Alex K. Williamson
2006, Fact Sheet 2006-3101
The U.S. Geological Survey began its National Water-Quality Assessment (NAWQA) Program in 1991, systematically collecting chemical, biological, and physical water-quality data from study units (basins) across the Nation. In 1999, the NAWQA Program developed a data warehouse to better facilitate national and regional analysis of data from 36 study units...

Palila Restoration: Lessons from Long-term Research
Water Resources Division, U.S. Geological Survey
2006, Fact Sheet 2006-3104
BACKGROUND The palila (Loxioides bailleui) is a member of the Hawaiian honeycreeper family of birds (Drepanidinae), which is renowned for the profusion of species - many with bizarre bills and specialized feeding habits - that radiated from a single ancestral type. Most of the 57 or so honeycreeper species are extinct,...
