This study outlines a pragmatic professional-judgment assessment of the potential for using low-tech process-based restoration (LTPBR) approaches for restoring riverscapes with beavers in Park County, Colorado. The method allows professionals to apply knowledge and data from many sources in the evaluation of current beaver activity, capacity, limit...

This paper presents a new way of thinking about stream restoration as an ecological healing process, rather than as an engineering design-build exercise. We present an operational definition of ecological health for application to streams and show how it can be applied as the diagnosis, treatment, and ongoing care of impaired stream ecosystems. O...
Conference Paper

This paper is intended to reinvigorate a discussion of ethics and incorporation of ethical thought into stream management plans and decision-making. I begin with the apparent dilemma of whether we manage streams for human desires versus stream ecosystem health. I then introduce concepts from contemporary environmental ethics including natural value...

The importance of biological drivers in stream restoration. Examples of process-based restoration on beaver-mediated streams in the Rocky Mountain headwaters.
Conference Paper

We explored the concepts of equilibrium and stability and their role in stream assessment and restoration. The Natural Equilibrium Paradigm—the idea that streams naturally strive towards an optimally stable form that balances flow and sediment transport—is the underlying premise of stream stability definitions that presume static channel morphology...
Conference Paper
Full-text available
Prior to human disturbance, many of Colorado's small alluvial headwaters streams were naturally anastomosed wooded beaver streams or broad grassy wet meadows best described as Stage 0 in Cluer's and Thorne's 2013 Stream Evolution Model. Restoring natural Stage 0 streams provides greater hydrological, ecological, and habitat benefits compared to sta...
Conference Paper
Full-text available
Today's dominance of entrenched single-thread channels with dry, disconnected riparian zones Southern Rockies headwaters alluvial streams is at least partially due to widespread anthropogenic conversion from native beaver streams. The conversion is explained using Cluer and Thorne's 2013 Stream Evolution Model (SEM) as a shift from Stage 0 to Stage...

Goals: 1. To understand the history and basis of equilibrium theory in fluvial geomorphology 2. To understand the implications of the natural equilibrium paradigm in definitions of stream stability, stream functional assessment, and stream restoration.
