CARBON AND NITROGEN CYCLING IN GIANT CANE (ARUNDINARIA GIGANTEA (WALT.) MUHL.) RIPARIAN ECOSYSTEMS
… giant canebrakes to become critically endangered ecosystems. Increasing evidence suggests the loss of canebrakes has directly impacted riparian ecosystems, resulting in increased soil erosion, poorer water quality, and reduced flood control. Cane's ecological importance has led to an increased …

A Comparison of Wildlife Monitoring Techniques in Riparian Ecosystems of the Western United States
<p>Many riparian restoration projects in the western United States have not implemented monitoring plans. This lack of wildlife monitoring has resulted in a loss riparian ecosystem services and missed opportunities to conserve them. Data collected from wildlife monitoring assists researchers, …

Riparian willow decline in Colorado: interactions of ungulate browsing, native birds and fungi
… spp.) are critical components of Rocky Mountain riparian ecosystems. They provide food for ungulates and beavers; habitat for resident and migratory bird populations, and amphibians; and are integral components of the structure and function of montane riparian ecosystems. In Rocky Mountain …

Impacts of the invasive reed Arundo donax on biodiversity at the community-ecosystem level
… species that mostly impacts on sensitive riparian ecosystems. Arundo is also invasive in South Africa, though less is known about its ecology, biology, and impacts. Since California and the Western Cape of South AFrica have similar Mediterranean-type climates, we could assume that the …

Impacts of elk management and riparian condition on songbirds in Rocky Mountain National Park
… the western U.S. is having cascading effects on ecosystems. As in other western parks, riparian willow (Salix spp.) communities in Rocky Mountain National Park (RMNP) are declining as a result of a trophic cascade involving the local extinction of wolves (Canis lupus) and an exponential increase …

Habitat, landscape, and climate effects on riparian predator-prey interactions in a human-dominated ecosystem
… links between terrestrial and aquatic ecosystems, and may be particularly important in riparian ecosystems with highly variable habitat features in human-dominated landscapes. Climate models predict an increased frequency of summer drought and spring flooding events in the Midwestern …

Effective Mitigation of Sedimentation on Riparian Riverbeds and Salmonid Populations After Dam Removal
<p>Riparian ecosystems rely on longitudinal connectivity of their streams and tributaries to maintain a healthy ecosystem. Longitudinal connectivity is especially important for salmonid populations, which and rely on longitudinal connectivity to reach spawning habitat. Dams prevent longitudinal …

A multi-scale, hierarchical approach to map the location and condition of riparian zones in the southern Rockies ecoregion
Riparian zones are important for their contribution to biodiversity and ecosystem services, especially in the western United States where riparian zones occupy a small proportion of the landscape but support a majority of the biodiversity. Riparian zones are currently threatened by multiple …

Resident Participation in Watershed Management: Preference for Riparian Landscapes, Attitudes, and Behaviors- Case Study of Cedar River Watershed, Washington
… of urbanization and flooding with many other riparian ecosystems in the Pacific Northwest. Restoration of the watershed is not only beneficial to the ecological health of the River, but to the flood mitigation of private riverfront properties. Therefore, engaging the residents along the river …

Effects of herbivory as an ecological constraint of willow growth at a restored riparian corridor
<p>A critical component of nearly all riparian restoration projects is the rapid successful recovery of native vegetation. The dynamic conditions and diverse biotic community supported by riparian ecosystems can present numerous constraints to restoration efforts. This study investigated stunted …

Lessons learned from urban river restoration projects: application of restoration treatments on the Los Angeles River.
… management, to return many ecosystem services to riparian ecosystems. Additional objectives were to compare 1.) costs and 2.) ecosystem service restoration success between eight main on-site and eight off-site alternative treatments applicable to urban rivers. Restoration success was evaluated …

Monitoring and Managing River Corridors in the Midst of Growing Water Demand
Rivers and their surrounding riparian and subsurface ecosystems, known as river corridors, are important landscape features that provide a myriad of ecological and societal benefits. While the importance of riverine flooding has been widely acknowledged and extensively studied, very little research …

Environmental Flow Regime Recommendations for the Promotion of Salicaceae Seedling Recruitment in California’s Central Valley
… major repercussions on the processes that drive riparian ecosystems. Repercussions to river processes are manifested in the degradation of riparian forest health. This is evident in the rivers of California’s Central Valley, where altered flow regimes are present in all of its major rivers. As a …

Initial response of riparian vegetation to dam removal on the Elwha River, Washington
<p>"Riparian zones, the interfaces between terrestrial and aquatic ecosystems, provide numerous ecosystem functions such as wildlife habitat, erosion control, nutrient and energy storage, buffering of sediment and pollution, and maintenance of biodiversity. Worldwide, riparian ecosystems are …

NATURAL REGENERATION DYNAMICS AND SURVIVAL INFLUENCED BY ABIOTIC AND BIOTIC FACTORS IN A BOTTOMLAND HARDWOOD FOREST
<p>Riparian ecosystems are vital to the landscape, providing critical services including water filtration and purification, flood and erosion control, carbon sequestration, biodiversity support, and aesthetic value. Bottomland hardwood forests, however, are threatened by invasive species, land …

Water flow and heat transport modelling at the interface between river and aquifer
… ecological health and resilience of streams and riparian ecosystems. Solute and heat exchange across this interface is driven by the advection of water. Characterizing the flow conditions in the streambed is challenging as flow patterns are often complex and multidimensional, driven by surface …

Vegetation colonization within exposed reservoirs following dam removal on the Elwha River, Washington
"Riparian ecosystems are important for ecological functioning of rivers, and are significantly impacted by dams. With over 50% of large dams in the U.S. beyond their life expectancy, dam removal is increasingly being considered to eliminate aging infrastructure and restore ecosystems. There have …

Management and Mother Nature: piping plover demography and condition in response to flooding on the Missouri River
Globally, riparian ecosystems are in decline due to anthropogenic modifications including damming, channelization and the conversion of the floodplain for human use. These changes can profoundly affect riparian species as many have adapted to the historical dynamism of these ecosystems. On the …

Conservation implications of the invasion of southern Africa by alien organisms
Alien species known to be invading untransformed ecosystems in southern Africa, and, more particularly, those inside nature reserves, were identified. The extent and ecological impacts of these invasions were assessed. Their control within reserves was also evaluated. Research approaches used were; …

A damming history: an analysis on the legacy effects of beaver dams on the composition and structure of a montane riparian ecosystem
… (Castor canadensis) increases heterogeneity in riparian systems through dam-building activities, resulting in diverse wetland complexes. This study explored the impact that historic, off-channel beaver dams have on the structure and composition of the surrounding vegetative communities. …
