The purpose of this design manual is to provide restoration practitioners with guidelines for implementing a subset of low-tech tools—namely beaver dam analogues (BDAs) and post-assisted log structures (PALS)—for initiating process-based restoration in structurally-starved riverscapes. While the concept of process-based restoration in riverscapes has been advocated for at least two decades, details and specific examples on how to implement it remain sparse. Here, we describe ‘low-tech process-based restoration’ (LT-PBR) as a practice of using simple, low unit-cost, structural additions (e.g. wood and beaver dams) to riverscapes to mimic functions and initiate specific processes. Hallmarks of this approach include:
- An explicit focus on the processes that a low-tech restoration intervention is meant to promote
- A conscious effort to use cost-effective, low-tech treatments (e.g. hand-built, natural materials, non-engineered, short-term design life-spans) because of the need to efficiently scale-up application.
- ‘Letting the system do the work’ which defers critical decision making to riverscapes and nature’s ecosystem engineers

Registration Closed - Due to COVID-19, the NRCS, Working Lands for Wildlife Low-Tech PBR Field Workshop Series was switched to a virtual webinar format. This year’s in-person trainings would have reached 100 invited participants in two events. The equivalent publicly offered workshops are normally $900 to $1100 per person. Thanks to the NRCS Working Lands for Wildlife partnership, this virtual workshop is available for anyone interested on August 11-14, 2020. We can accommodate up to the first 1000, and you can pick and choose from five modules. Those that can’t make those dates can take advantage of self-paced recordings, exercises and content after the workshop. Thank you NRCS!
