Demonstration Restoration Measures in Tributaries of the Vindel River Catchment Ecology and Society
Holmqvist, Daniel; Vindel River Fishery Advisory Board; daniel.holmqvist@lycksele.se.
Some ecological restoration projects include elements of trial and error where new measures are repeatedly tried, evaluated, and modified until satisfactory results are achieved. Thereafter, the resulting methods may be applied on larger scales. A difficult step is judging whether developed “best-practice” methods have become reasonably ecologically functional or whether further experimentation “demonstration” methods can lead to yet better results. Here, we use a stream restoration project as a case study for evaluating methods and abiotic effects and outlining stakeholder support for demonstration restoration measures, rather than only using best-practice methods. Our work was located in the Vindel River system, a...

Reza; University of Memphis; pezeshki22@yahoo.com; Wilson, Glen V.; USDA ARS National Sedimentation Laboratory; GVWilson@msa-oxford.ars.usda.gov; Wu, Weiming; University of Mississippi National Center for Computational Hydroscience and Engineering; wuwm@ncche.olemiss.edu; Dabney, Seth M.; USDA ARS National Sedimentation Laboratory; sdabney@msa-oxford.ars.usda.gov.
The restoration of potentially species-rich stream ecosystems in physically unstable environments is challenging, and few attempts have been evaluated scientifically. Restoration approaches that involve living and dead native vegetation are attractive economically and from an ecological standpoint. A 2-km reach of an incised, sand-bed stream in northern Mississippi was treated with large wood structures and willow plantings to trigger responses that would result in increasing similarity with a lightly degraded reference stream. Experimental approaches for stream bank and gully stabilization were also examined. Although the project was initially successful in producing improved aquatic habitat, after 4 yr it had failed to effectively address issues related...
