| E | 235439 | 141 | Produce Other Reports | Other Reports for BPA | Building on FY16—FY21 work and reporting (Johnson 2016, 2017, 2018, and 2019 ; Diefenderfer and Johnson 2021 ), three research elements and one manuscript element will be undertaken for WE 141. Travel for WE 141 (pending appropriate safety evaluations) will involve one 3-day one-person trip from Sequim to Astoria vicinity for the ongoing reed canarygrass control experiment, one 3-day two-person trips Sequim/Portland for meetings, and four 3-day two-person trips to Astoria for surface elevation table monitoring.
1. Reed Canarygrass (RCG) Experiment – A six-year field experiment on reed canarygrass control methods is currently underway by the Columbia Land Trust at restoration projects at Kandoll Farm (commenced in 2016) and Kerry Island (commenced in 2017). (See the formal experimental design in Appendix C, Johnson 2016.) Preliminary results were delivered in October 2018 (see Appendix B in Johnson 2018), during a CEERP science seminar on April 17, 2019 (https://youtu.be/_JWtuU_qMN0), in October 2019 (see Appendix A in Johnson 2019), in January 2021 (see Appendix A in Diefenderfer and Johnson 2021), and during a virtual session of the National Conference on Ecosystem Restoration in July, 2021 (speaker, I. Sinks; moderator, A. Borde; https://conference.ifas.ufl.edu/ncer2021/documents/NCER-2021-Agenda.pdf).
During summer 2022, PNNL will sample vegetation at one study site: Kerry Island (fifth year after the initial treatment). The experiment is scheduled to be completed with that final summer vegetation sampling, although sampling may occur in the future to assess the effects of relaxation of control measures. For FY22, PNNL will produce a draft manuscript on the RCG experiment results for peer-reviewed publication and include it by reference in the annual report for Project No. 2002-077-00.
2. Groundwork for Implementing the Large Woody Debris (LWD) Study Plan – The ecological function of LWD in estuaries is poorly understood. ERTG (2012 ) listed LWD as a key uncertainty in CEERP. The 2018 CEERP Synthesis Memo (Johnson et al. 2018 ) noted, “…the considerable uncertainty about the use of LWD in restoration projects should be the subject of focused investigation.” Using ERTG (2016 ) as a basis, we drafted a study plan to address the ecological function of LWD in estuarine channels during FY19 and iteratively improved it through discussions with CEERP restoration practitioners, wetland restoration engineers, incorporation of the prey resource in addition to the fish resource, and further literature review regarding methods. The study plan emphasizes linkages between large wood placement and effects on food webs supporting juvenile salmon, including sampling for fish, insects, water currents, channel cross-sections, and other parameters within a formal statistical design (Diefenderfer and Johnson 2021, Appendix D). During FY20, we began preparations for implementing the LWD study plan by assessing the availability of planned restoration sites with LWD placement for potential study areas. In August of FY21, methods testing is planned in a reconnaissance visit to a wetland with large wood in the channel.
The plan does not specify the study site(s) and collaborating project sponsor(s), although sites with existing large wood placement were inventoried. Supporting the feasibility study for identification of sites/sponsors and implementation planning will be the focus of FY22 work. Study sites may be existing sites with the addition of LW according to the study design, or new sites where the design is implemented. The time horizon to implement a LWD study could be 3-5 years starting with FY22–FY23. For FY22, PNNL will produce a progress report on groundwork for implementing the LWD study plan and include it as an appendix in the annual report for Project No. 2002-077-00.
3. Collaborative Analysis of Sediment Pin Data
Technical review of the reported CEERP restoration sediment accretion rate data during FY21, by request of the ERTG, found that Level 3 data collected by sponsors has been delivered according to contracts but not analyzed and reported unless the site is selected for Level 2 data collection, meaning the last comprehensive report was for data collected in 2016 in Synthesis Memorandum II (Johnson et al. 20186). Sites to be restored are behind dikes and have subsided in the absence of sediment supply, so the assumption is that sediment accretion is beneficial for the resumption of ecosystem processes. Accretion is also viewed as a means of mitigating the risk of sea level rise or flow changes that could impact restored wetlands. However, a positive accretion rate depends on sediment supply which in turn is limited by the reservoir system.
For this analysis, collaboration with sponsors who collect Level 3 data in accordance with the AEMR framework will be central because it has been shown that localized, observational information is crucial to explaining sediment accretion rates (Diefenderfer et al. 2021, Supporting Information, Data Set 1 ). Spatial patterns and temporal trends will be examined at multiple scales—within site where data permit, at the reach scale, tidal river versus estuary, and LCRE-wide. The recently introduced new metric, 7-day average daily maximum depth (7DADMD)8, will also be calculated using Level 3 water surface elevation and land elevation data where available. The utility of the data for physics-based models of reference wetland complexes will be evaluated.
4. Manuscripts – Publishing the results of RDC research in the peer-reviewed literature is fundamental to a strong scientific basis for CEERP. To date, four RDC-related manuscripts have been published, as summarized in the following table. (Note, in some cases, studies in addition to RDC contributed to the manuscript.) During the FY22, we will complete and submit manuscript on a spruce swamp reference model (#6) and the large wood and plant productivity manuscripts, now combined (#8). We will respond to comments from the peer-review process for manuscript (#7), as received. We will summarize progress and status of RDC-related manuscripts in the FY22 annual report for Project No. 2002-077-00. | $108,110 | 36.63% | 11/01/2022 | 10/31/2023 |

| H | 235442 | 157 | Collect/Generate/Validate Field and Lab Data | Surface Elevation Tables (SETs) | A more reliable method than sediment pins may be needed to accurately and precisely measure sediment accretion rates in wetlands in the LCRE. Although the sediment pin method (Roegner et al. 2009) is an inexpensive means of obtaining estimates of surface sediment accretion or erosion in wetlands, the method has known deficiencies, such as not remaining stationary. Surface elevation tables (SETs) are a state-of-the-art method for measuring surface sediment accretion rates.
“When attached to a bench mark pipe or rod, the SET provides a constant reference plane in space from which the distance to the sediment surface can be measured by means of pins lowered to the sediment surface. Repeated measurements of elevation can be made with high precision because the orientation of the table in space remains fixed for each sampling” (from https://www.usgs.gov/science/regions/northeast/maryland/science/surface-elevation-table?qt-science_center_objects=0#qt-science_center_objects).
During FY18–FY21, PNNL installed eight SETs representing tidal river and estuarine system zones, and energetic conditions including bay, main stem river, and tributary to the extent possible, and a gradient from marsh to forested wetland. To validate the sediment accretion stake method, and thus provide a level of confidence for the large existing dataset for sediment accretion, some SETs were placed at Ecosystem Monitoring Program long-term study sites where stakes have already been in place for multiple years. SET data will also directly inform wetland restoration and any future morphological modeling of the system. During FY23, we propose to continue making surface elevation measurements at most of the sites four times in the course of the year (January, April, July, and October). FY23 will be the 2nd year when SETs will be deployed at all eight sampling locations for a full year. We anticipate at least five years of data collection, i.e., through FY24, to obtain SET data over a range of river discharge conditions. For FY23, we will document the SET field activities along with preliminary sediment accretion/erosion data and include it as an appendix in the annual report for Project No. 2002-077-00. | $95,258 | 32.27% | 11/01/2022 | 10/31/2023 |
