Effects of riparian zone buffer widths on vegetation diversity in southern Appalachian headwater catchments
In mountainous areas such as the southern Appalachians USA, riparian zones are difficult to define. Vegetation is a commonly used riparian indicator and plays a key role in protecting water resources, but adequate knowledge of floristic responses to riparian disturbances is lacking. Our objective was to quantify changes in stand-level floristic diversity of riparian plant communities before (20...
متن کاملCan structural and functional characteristics be used to identify riparian zone width in southern Appalachian headwater catchments?
We characterized structural and functional attributes along hills lope gradients in headwater catchments. We endeavored to identify parameters that described significant transitions along the hills lope. On each of four catchments, we installed eight 50 m transects perpendicular to the stream. Structural attributes included woody and herbaceous vegetation; woody debris and forest floor mass, ni...
متن کاملRiparian zones in southern Appalachian headwater catchments: Carbon and nitrogen responses to forest cutting
There is little understanding about the role eastern US forested headwater riparian areas play in protecting aquatic habitats and water quality from impacts of side slope forest harvest. To better understand this important riparian area function, we selected three sites frommanagement units with a 2-age regeneration silvicultural prescription located on the Nantahala National Forest, North Caro...
متن کاملDoes stream flow structure woody riparian vegetation in subtropical catchments?
The primary objective of this study was to test the relevance of hydrological classification and class differences to the characteristics of woody riparian vegetation in a subtropical landscape in Queensland, Australia. We followed classification procedures of the environmental flow framework ELOHA - Ecological Limits of Hydrologic Alteration. Riparian surveys at 44 sites distributed across fiv...
متن کاملEfficacy of riparian buffers in mitigating local population declines and the effects of even-aged timber harvest on larval salamanders
ARTICLE INFO ABSTRACT Artide history: Keywords: Desmognathus quadmmculatus Ellrycea wilderae Headwater stream Riparian buffer Salamander larvae Sedimentation Headwater streams are an important and prevalent feature of the eastern North American landscape. These streams provide a wealth of ecosystem services and support tremendous biological diversity, which is predominated by salamanders in the...
