Riparian Rule Analysis: Context
Throughout analysis, ODF worked with:
– Board advisory committees:
• Regional Forest Practices Committees,
• Committee for Family Forestlands,
–stakeholders
–partner agencies
![Page 10: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/10.jpg)
Rule Analysis: RipStream Predictions
• Based on vegetation plots, shade and stream temperature data
–Estimates of harvest-related warming
–Predictions of proposed harvest effects on temperature
–Measure of confidence in model results
Developed in consultation with external review team, professional statisticians
![Page 11: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/11.jpg)

Rule Analysis: Geographic Extent
• Two aspects of where rules could apply:
–Geographic Regions in W. Oregon
– Stream Extent: which small & medium streams
• Only streams with salmon, steelhead, or bull trout (SSBT)
• Fish streams
• Combination of SSBT and F streams
• Largely policy questions, science provides minimal direction
![Page 14: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/14.jpg)
Rule Analysis: W. Oregon Geographic Regions • Information from Systematic Review • Implications of current policy as identified in rule BOTH equivocal
![Page 15: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/15.jpg)
Rule Analysis: Stream Extent
Guidance:
• Rule analysis objective:
Establish riparian protection measures (Small, Medium F streams) to meet PCW
• PCW [OAR 340-041-0028 (11)(a)]:
–“…applies to all sources taken together at the point of maximum impact where salmon, steelhead or bull trout [SSBT] are present.”
– Indicates need contributing waters (i.e., upstream)]
Board bookends (small & medium streams): SSBT to all F
![Page 16: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/16.jpg)
Rule Analysis: Stream Extent - upstream Challenges: 1. Distance upstream of main stem: some science, lots of variance
Remaining temperature change downstream of harvest
![Page 17: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/17.jpg)
Rule Analysis: Stream Extent - upstream
Challenges:
2. Tributaries: volume-weighted flow (complicated modeling, much uncertainty) plus challenge #1
3. All sources taken together: timing of heat load arrival from multiple streams at point of maximum impact
Minimal scientific direction; Board policy call
![Page 18: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/18.jpg)
Summary of Information provided to Board
For each prescription: • Predicted temperature change with measure of
confidence • Equivalent fixed width of buffer • Large wood recruitment, decrease in shade, fish
response • Additional encumbered acres by georegion
ownership, stream type (SSBT or all Fish) • Land and Timber Value of these additional
encumbered acres

1. Watershed- and Reach-scale Studies
A. Watershed studies (e.g., Hinkle, Alsea, Trask)
– More info on why/process at a site
– Few sites, less inference beyond sites
B. Reach-scale studies (e.g.,RipStream)
– More sites, greater inference across landscape and “population”-level effects
– Less info on why/process
C. Study types = complimentary
![Page 43: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/43.jpg)
Conclusions: RipStream & Other studies
1. Wide range in shade & temperature responses to harvest-adjacent buffers, yet clear relationships exist:
– Shade with basal area, buffer width
– Temperature with buffer width
2. Temperature & shade variability:
– Appears to decrease with increasing: buffer width, basal area
– Reason to assess effectiveness across landscape for robust statistics

South-sided Buffers
• 1 study, 3 sites; temperature change: 0.0-1.4 °C
• Additional Encumbered Acres & Value, large wood recruitment
• Numerous assumptions, thus put bounds on values
![Page 47: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/47.jpg)
Fish Response
• Responses from 5 fish biologists • One biologist convened 2 panels of 12
additional fish biologists • State and federal agencies, landowners,
environmental community • Matrix Responses: { + - 0 ? } • Complexity, uncertainty of response at stream
reach level • Different assumptions, metrics
![Page 48: Riparian Rule Analysis for Oregon Board of Forestry · –Oregon Board of Forestry (“Board”) finding of degradation (PCW)→ began rule analysis (Jan. 2012) –Rule objective](https://reader033.vdocument.in/reader033/viewer/2022050508/5f999ddcb4776f561367129a/html5/thumbnails/48.jpg)
• Common themes: • Existing temperatures matter
• Different starting points affect responses
• Complex issue, particularly when not taking into
account other factors (large wood availability, climate change, cumulative effects, other stream characteristics)

ORS 527.765 Factors to Consider
a) Beneficial uses of waters: SSBT b) Effects of past practices on beneficial uses: RipStream
sites were second growth; WRC results c) Appropriate practices of other forest managers: other
states, Oregon State Forests, Systematic Review d) Feasibility
i. Economic: info from ODF ii. Institutional: ODF staff iii. Technical: RFPCs
e) Natural variations in geomorphology, hydrology: Systematic Review, breadth of RipStream sites, Geographic Regions

• Attain Desired Future Conditions
• Avoid unintended consequences

Board Considerations & Origin of Analysis Framework
• Current FPA policy framework already intertwines
– Meeting the PCW to the maximum extent practicable
– Riparian desired future condition
• Board expressed desire to consider unintended consequences
– Economic impacts
– Active management of riparian areas & large wood placement
– CZARA disapproval
– Data extrapolation
– Complex or layered scientific assumptions

Geographic Extent Policy Considerations
• Insufficient science to support empirical Board decision
• Reaffirm or alter current policy re: rule specific to geographic region and stream size?
–Reaffirm policy – Limit rule analysis to Coast Range, assume a risk-intolerant position re:extrapolating RipStream results.
–Alter policy – Assume risk-tolerant position relative to RipStream results, include 2+ regions and/or define new region(s), and/or establish a single protection standard across all streams regardless of size.
• CZARA Disapproval

Recommendations
• The Department recommends that the Board discuss the policy issues, using the above framework and all the information it has received to develop a set of prescription components that meet the PCW criterion to the maximum extent practicable, consistent with the ORS 527.765 factors and required ORS 527.714 findings.
• The Department also recommends that the Board include more than one prescription choice, e.g., a no-cut prescription, a variable retention prescription, and/or alternate prescription approach to increase forestland owner flexibility and minimize unintended consequences.
