Per the comment letter we received on December 19, 2019, RES is providing this adaptative management plan to address the low stem density/poor growth problem. Comment: An Adaptive Management Plan (AMP) should be provided for the low growth/density areas and the area that exhibits characteristics of open water, rather than a wetland complex. Plan: RES plans on addressing the low stem density/poor growth problem by replanting the areas using species and planting methods that are known to be successful in standing water. The areas onsite that are exhibiting the low stem density/poor growth have surface water up to 18 inches deep present year-round. Table 1 below outlines the species and amount of trees RES will plant. RES plans on planting 1,400 whips and 1,300 livestakes/poles which represent about 380 stems per acre, and 2,700 trees total. Table 1. Planting species and quantities for Arrington Bridge III mitigation bank. Species Type Size (ft) Amount Bald cypress Whip 4 750 Water tupelo Whip 2 150 Green ash Whip 4 500 Black willow Livestake 3 750 Buttonbush Livestake 3 50 Black willow Pole 6 500 Whip Total 1,400 Livestake/Pole Total 1,300 Grand Total 2,700 A combination of livestake approaches will be used. Three -foot -tall livestakes will be inserted directly into the soil, ensuring some buds remain above the water level. Additionally, livestake poles that are six feet in length will be planted in the deepest pool onsite, near VP 11. Planters will ensure buds remain above the water level and the poles will discourage use of the open water by waterfowl. res.us 0 Whips (two- to four -foot -long bareroot trees) will be prepped before planting by removing the lateral roots and trimming the tap root down to nine inches before they are stick planted directly into the soil by pushing them into the ground up to their root collar. The stick planting method outlined in the "Riparian & Wetland Tree Planting Pocket Guide For North Carolina 3rd Edition" will be followed. This method works best where soil is saturated and likely to remain saturated throughout the growing season. Stanturf et al, explains that the trimming of the root system allows the tree to quickly begin growing a water -adapted root system upon re -growth. Trees that are not trimmed will drain a large amount of energy shedding their old root system before developing one better for standing water. Additionally, planting without a hole gives the stems better contact with the soil around them and reduces the chances of the stems floating out of the soil. RES plans to perform the replanting by the beginning of the 2020 growing season. Once work is completed, RES will provide written notification to the IRT along with photo documentation to inform work has been completed. A map is attached to show the areas that will be replanted. RES plans to keep the existing vegetative success criteria (260 stems per acre by Year 5 and 210 stems per acre by Year 7) and will monitor vegetation in MY6 to capture an extra year of data.

A few of us met with RES last week, and there was a brief mention of some of the methods they planned to use to mitigate the open water area. Please provide any comments within 15 days (March 10th). At the conclusion of the 15-day comment period, pending there are no concerns, I will issue the Year 4 Monitoring Credit Release, as outlined in my October 31, 2019 email.
