Urban Riparian Areas: Ecological And Streamside-Ordinance Assessments
… have been established in many urbanizing areas; however, there has been a paucity of assessments of the effectiveness of such ordinances. A quantitative assessment of the ecological impairments in an urban river system can provide a key component in a basin-scale management plan. A study …

Desired Future Conditions of Riparian Areas on Southeastern National Forests
… management on public lands. I evaluated DFCs of riparian areas on national forests in the southern Appalachian mountains and evaluated a process for involving the public in development of DFCs for riparian areas on the Jefferson National Forest. First, I identified the major components, …

Examination of small mammal diversity in the riparian areas of Walden, Tennessee
… B. Examination of Small Mammal Diversity in the Riparian Areas of Walden, Tennessee Thesis under the direction of Robert D. Keller, Ph.D., Assistant Professor of Biology It has been hypothesized that riparian zones are prime conservation habitats and can be used as indicators of general ecosystem …

Organic Matter Processes of Constructed Streams and Associated Riparian Areas in the Coalfields of Southwest Virginia
… Appalachian headwater streams in coalfield areas are prone to mining disturbances, and compensatory mitigation is required in cases of documented impacts. Stream construction on reclaimed mines is a common mitigation strategy. Streams constructed as compensatory mitigation are meant to …

Extent And Distribution Of Montane Riparian Zone Vegetation And Representation In Protected Areas In The Sky Island Region Of The Southwestern United States
… most vertebrate biodiversity is dependent on riparian areas for all or some of their life cycles. Riparian vegetation is threatened by human impacts and climate change. Though riparian vegetation along rivers and major perennial streams is already mapped in this region, vegetation in ephemeral …

The Training, Use, and Water Quality Effects of Riparian Proper Functioning Condition Assessment in Nevada
The limited spatial extent of riparian systems in Nevada belies their importance to the production of ecosystem services by the landscape as a whole. Management of these systems is complicated by legacy effects of historic management, contrasting and often conflicting perspectives among …

Riparian management: an exploration into connecting the biophysical and social sciences
… actual uptake of this integration has been slow. Riparian areas are complex interfaces between terrestrial and aquatic environments and their sound management provides great opportunities to mitigate the impact of catchment activities on the ecological health and water quality of streams and …

Impacts of Fire on Bats in the Central Appalachians
… in this portion of the central Appalachians. Riparian areas are particularly important for bats, and serve as foraging and drinking areas, roost sites, and travel corridors. Because fire impacts dry upland and mesic riparian areas differently, is possible that fire will impact bats differently …

Fantastic Birds and Where to Find Them
… of Willow Flycatchers migrate between the riparian landscapes in the western and southwestern United States to the riparian areas in tropical dry forests along the Pacific coast of Central America. The predictive model of potential habitat suitability will be corroborated on the ground by …

Bat Activity Across Urban Forest Plantings in Lexington, Kentucky
… 10 years in age, plantings within 100 m of riparian areas, and at plantings with a perimeter-to-area ratio of 420 m/ha or smaller for all phonic groups, except hoary bats (Lasiurus cinereus) which exhibited habitat affinities counter to this. AIC model selection suggested that while various …

Impact of Large Herbivore Use in Meadows on Lentic Function, Wetland Extent and Vegetation Hydric Status
… and wild horses disproportionately favor riparian areas over uplands when seasonal temperatures are high or upland vegetation becomes dry, especially in flatter, more accessible terrain. Long-term trampling by excess or prolonged stocking can cause damage to riparian roots, reducing the …

Habitat selection by the elegant trogon (Trogon elegans) at multiple scales.
… and Santa Rita mountains used both upland and riparian areas, and selectively used sites with dense vegetation within those areas. At the microsite scale, nest sites of trogons were primarily located in sycamore trees in riparian areas. Successful nests could be discriminated from unsuccessful …

Vegetation community development eight years after harvesting in small streams buffers at the Malcolm Knapp Research Forest
Riparian areas connect terrestrial and aquatic environments. The objectives of this research were to compare the vegetation community composition and structure eight years after harvesting and to explore successional trends among buffer widths at year eight after disturbance and in a …

HABITAT USE AND THE EFFECTS OF DISTURBANCE ON WINTERING BIRDS USING RIPARIAN HABITATS IN SONORA, MEXICO
Riparian systems are important for breeding bird communities and are highly used as migratory corridors; however, their importance for wintering birds has not been assessed systematically. In order to assess the value of riparian areas for birds wintering in Sonora, data from 1,816 standard point …

Effects of Land Use on Hellbenders (Cryptobranchus alleganiensis) at Multiple Levels and Efficacy of Artificial Shelters as a Monitoring Tool
… as forest cover increased in collective upstream riparian areas, primarily as the result of increased recruitment of new adults to local populations (rather than increased apparent survival of adults). Populations in lesser forested areas were declining and composed largely of relatively old …
