Day 1 - Intro to Low-Tech Process Based Restoration
1. Logistics and Introductions
The workshop kicks off with some introductions and logistics.
2. Background and purpose
These talks are elaborated in Chapter 1 of design manual.
3. Build your first Beaver Dam Analogue exercise
This exercise is elaborated in the Pocket Guide.
4. Introduction to low-tech approaches
5. Guiding Principles
Perhaps the most important aspect to understand about low-tech process-based restoration: the underlying principles:
This talk is elaborated in Chapter 2 of design manual.
Day 2 - Planning and Designing Low-Tech Riparian Restoration
6. Beaver Ecology
In order to take advantage of beaver dam activity (one of the two key process we focus on in low-tech process-based restoration of structurally starved systems), we need to understand a bit about beaver ecology and why they build dams in the first place.
This talk is elaborated in Ben Goldfarb’s new award winning book: Eager - The Surprising Secret Life of Beaver and Why they Matter.
7. Conservation Planning Process
We reframe the process of undertaking low-tech restoration within the NRCS’s Conservation Planning Process. Among the key adaptations of the Conservation Planning Process are learning how to read riverscapes.
- Introduction to Conservation Planning Process & Reading Riverscapes
- Riverscape Valley Setting Excercise - Handout
This talk is elaborated in Chapter 3 of design manual.
8. Planning in Detail
After returning from a field trip where we focused on reading riverscapes and identifying structurally-forced alterations to hydraulic and geomorphic processes, we worked through the planning phase of the CPP in detail with a series of desktop exercises.
- Conservation Planning Process Intro - Slides
- Valley Bottom Mapping & Risks Assessment Exercise - Handout
This talk is elaborated in Chapter 3 of design manual.
Mimicking and promoting wood accumulation and beaver dam activity
We take a break from some of the exercises to focus on some of the science behind mimicking and promoting wood accumulation and beaver dam activity. Specifically, we focus on two Intensively Monitored Watershed Case Studies that have been the catalysts for low-tech process based restoration.
These talks are elaborated in Chapter 4 of design manual.
9. Case Study: Asotin Creek
10. Case Study: Bridge Creek
Extra Case Study Examples
We walk through the LT-PBR design process to prepare participants for doing their own designs in Day 3 in the field:
Example of Vision
- Vision for Phased Implementation
- Simple Indicators for Monitoring
- Concept of Overlapping Complex Zones of Influence
We covered implementation on Day 3 in the field, but here are some overview slides:
This is based mainly on Chapter 6 of the design manual.
A Rancher’s Story: Reintroducing beaver to bring back perennial flow
- A Rancher’s Story: Reintroducing beaver to bring back perennial flow (Wilde et al. (2019)) If you missed it, see a version Jay gave last year here.
Day 3 - Building Low-Tech Restoration Structures
- Design Exercise - (Chapter 4 - Design Manual); Pocket Guide)
- Split into groups, discuss design objectives for their complex, layout project with flags Logistics, Safety & Post Pounding (Chapter 6 - Design Manual); Pocket Guide)
- Hands-on construction of various structures (PALS, Post-Assisted BDAs, Postless BDAs; Chapter 6 - Design Manual) - Design Manual; Pocket Guide)
- Review and critique constructed structures
- Discussions on adaptive management (Chapter 3, 4 & 6) - Design Manual)
- Workshop synthesis (review principles) & where to turn for help
