Maps and a brief overview of the project were presented by Wildlands and DMS at the parking area along the farm road near the downstream culvert crossing on Shake Rag Branch. From there, the group proceeded to walk the site with the goal to see representative portions of the project. 1. Paul asked Wildlands to describe any concerns they have about the project. Wildlands responded that though the site has demonstrated good stem density, the tree height has lagged for which the main cause appears to be deer browse and some competition with herbaceous vegetation. Joe described actions that the Wildlands stewardship team has taken to boost growth and give the stems a competitive advantage by adding soil amendments and repellex tablets, and conducting ring sprays in areas of dense tall fescue. Jake also asserted that there were some lessons learned in regard to managing pasture grasses during construction that has been improved upon for newer projects. 2. Another concern that was discussed was the encroachments that have occurred along the unfenced portions of the lower conservation easement boundary. Wildlands confirmed that the mowing encroachments documented in the MY3 (2022) monitoring report have been resolved by adding posts and communicating with the landowner. Jake and Matthew described additional encroachments that were first observed in January 2023 due to landowner waterline activities that caused some disturbance SHAKE RAG Mitigation Site – Meeting Notes Wildlands Engineering, Inc. page 2 SHAKE RAG Mitigation Site MY4 IRT Site Walk of the vegetation within the portion of the UT4 easement adjacent to the farm road. Joe described actions taken to resolve the new encroachments which included reseeding and replanting container trees in those areas. The waterline, an overflow line from an upslope spring box, was redirected into the adjacent easement break near the culvert crossing (outside of the CE). Wildlands has had several successful discussions with the landowner to emphasize the importance of not disturbing any part of the conservation easement. Mimi confirmed that this will be documented in the MY4 (2023) monitoring report. 3. The group then walked to the UT4 crossing to observe where the new encroachments occurred and view the improvement in vegetation. 4. Continuing up the valley along the UT4, IRT members observed several examples of successful ring sprays with no collateral damage to the planted stems. It was noted that though some of the planted stems are small, they are healthy and showing signs of vigorous new growth this year. 5. The group walked up to the jurisdictional start of UT4 where baseflow was observed. IRT members noted some discontinuous flow under larger rock structures, but the stream was not exhibiting stability issues. Mac asked if the stream was monitored for flow. Mimi responded that since it is classified as perennial, there was no required monitoring for continuous flow and that there is a gage located downstream used to document bankfull events. 6. The group then walked back towards the lower Shake Rag Branch crossing and up the main stem’s valley to the UT3 confluence. On the way, the group noted liking the large culverts and also the wetland area in the vicinity of UT8. Jake described the repairs that occurred in April 2022 to address several localized instances of dislodged, piping structures and shifted riffle material. The repairs were observed to be functioning with some flow going under a few structures. IRT members asked about reasons for the damage. Wildlands described that large storms and tropical depressions that had come through the region during MY1 and MY2. Jake added that the substrate material size class used during construction that was harvested on site was variable and sometimes lacked mid-range size classes that may have aided in embedding the cascade riffle structures and that it could have been helpful to import material during construction. 7. Continuing up UT3, improvements in herbaceous coverage were observed near VP2. Joe described stewardship efforts which consisted of reseeding with a cover crop mixes for the last three seasons and spraying the area with compost tea beginning this year. 8. IRT members expressed interest in seeing a representative example of a steep headwater stream where no restoration work was done. The group decided to walk up to the upper reaches of Shake Rag Branch to view a reference condition for the site where seasonal flow conditions could be observed. Andrea brought up the topic of aquatic organism passage and whether some discontinuity of flow is a habitat issue for these headwater systems. Steve added that there is difficulty in determining the best design approach depending on the slope and drainage area for first order streams. Jake described some lessons learned working on steep headwater tributaries to utilize in the future such as limiting the number of pools and importing material with a better size class variety. 9. Walking back down Shake Rag Branch Reach 2, Wildlands noted the successful treatment of previously dense pockets of invasive species including tree of heaven (Ailanthus altissima) and multiflora rose (Rosa multiflora). 10. The group walked back to the parking area and circled up to summarize the main discussion points during the site walk. SHAKE RAG Mitigation Site – Meeting Notes Wildlands Engineering, Inc. page 3 SHAKE RAG Mitigation Site MY4 IRT Site Walk a. Steve was overall pleased with the site and though the low seasonal flow resulting in seeping under steep structure drops may be a habitat issue, it does not seem to be a stability issue. He indicated that he did not see a need to require any intervention scheme. (As a side note, Wildlands does do some minor handwork when piping issues are identified and thought to be due to construction related issues and not just low summertime flows). b. Erin requested that Wildlands be sure to document all the management actions done to address low stem heights in monitoring reports and was pleased with the progress of efforts to address prior conservation easement encroachments. c. Paul requested that Wildlands continue to document encroachment issues and keep a log of communications with the landowner regarding easement compliance discussions. This will allow for an easier transfer to DEQ stewardship when the history of the site is well documented. Paul also noted that it is preferable for these communications to remain internal between Wildlands and the landowner before needing to involve DMS. d. Andrea had left and was not present for summary discussion. The meeting concluded at 3:30 PM. All Attendees listed have been copied by email.
