Box 2750 Asheville, NC 28802 File Code: 2530 -3 Date: NC DWR, 401 & Buffer Permitting Unit 1650 Mail Service Center Raleigh, NC 27699 -1650 Dear NC DWR, This letter is to request Section 401 Water Quality Certification from the North Carolina Division of Water Quality for U.S. Forest Service project: Buck Creek Stream Restoration Proiect. Located on the Nantahala National Forest, Nantahala Ranger District in Macon County, North Carolina, this project is situated on Buck Creek and Little Buck Creek, in the Little Tennessee River Basin. The Forest Service is proposing to reduce in- channel erosion and sedimentation within Buck Creek and Little Buck Creek (Macon County) by stabilizing eroding stream banks. A trackhoe will be utilized to restore natural contours (dimension, pattern and profile) of Buck Creek, Little Buck Creek, and one unnamed tributary of Buck Creek. Excavated soil will be relocated on site to a stable location and native vegetation will be reestablished. Best management practices to prevent nonpoint- source water pollution will be utilized to protect water quality throughout the duration of the project. Approximately 184 feet of stream restoration would be required in Buck Creek and 150 feet in an unnamed tributary, and approximately 60 feet of stream restoration would be required in Little Buck Creek; a total of 394 feet of stream channel. Natural channel design concepts would be implemented to design channel dimension, pattern and profile using reference reach data from the up and down stream reaches. The following stream work is proposed: Site 1: A. Restore natural drainage at an old road crossing. Reestablish natural dimensions of the gulied tributary. Implement erosion control measures, including native plants, mulch, and place coir matting on stream banks. Plant native trees and shrubs for long -term stabilization along the stream channel with species beneficial to wildlife. B. Remove existing undersized stream crossings on the tributary and construct a natural bottom ford to provide aquatic passage while still allowing mowing access to the wildlife field. C. Stabilize 54 feet of stream bank on Buck Creek to a 2:1 slope and place seed, mulch and coir matting on the bank. Site 2: Construct a log vane in Buck Creek to reduce erosion of right bank and improve pool habitat. Site 3: Construct a log vane and a bankfull bench in Little Buck Creek to reduce erosion of right bank.

Project Description 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: Site 1. One old woods road contains a non - functional wooden culvert. A nearby wildlife field contains a small unnamed tributary of Buck Creek. The stream banks are steep and eroding into the tributary and into Buck Creek. In addition to the tributary, a section of Buck Creek channel bank in the wildlife opening is eroding where fill material was placed historically. Site 2. A section of Buck Creek is experiencing high stream bank erosion adjacent to a planted white pine stand. The stream channel has widened and has created mid- channel depositional bars. Site 3. A section of stream bank along Little Buck Creek has sloughed off into the creek. This area continues to erode into the stream. 3b. List the total estimated acreage of all existing wetlands on the property: 0 acre of wetlands. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: Approximately 184 feet of stream restoration would be required in Buck Creek and 150 feet in an unnamed tributary to Buck Creek, and approximately 60 feet of stream restoration would be required in Little Buck Creek; a total of 394 feet of stream channel. 3d. Explain the purpose of the proposed project: The goals and objectives of this project are to improve the health of the stream ecosystem by improving channel stability and habitat quality, along with improving riparian and streamside vegetation conditions. This will be accomplished with the construction of instream structures using trees found on site fashioned to protect eroded stream banks and create high quality aquatic habitat features. The desired condition is to have high quality riparian areas and aquatic habitat features that maintain hydrologic function, enhance stream stability, and minimize erosion. The proposed action is needed at this time, at these locations, because taking no action would lead to further erosion and sedimentation which, in turn, would cause further damage to aquatic habitat and the maintenance of designated uses. Page 4 of 14 3e. Describe the overall project in detail, including the type of equipment to be used: A trackhoe will be utilized to restore natural contours (dimension, pattern and profile) of Buck Creek, Little Buck Creek, and one unnamed tributary of Buck Creek. Excavated soil will be relocated on site to a stable location and native vegetation will be reestablished. Best management practices to prevent nonpoint- source water pollution will be utilized to protect water quality throughout the duration of the project. Approximately 184 feet of stream restoration would be required in Buck Creek and 150 feet in an unnamed tributary, and approximately 60 feet of stream restoration would be required in Little Buck Creek; a total of 394 feet of stream channel. Natural channel design concepts would be implemented to design channel dimension, pattern and profile using reference reach data from the up and down stream reach. See "Project Description" for details. The following stream work is proposed: Site 1: Tributary to Buck Creek: 1. Restore drainage at the old road crossing. 2. Lay back eroding bank to a 2:1 slope, minimum, along a 120 feet channel section, maintaining existing trees on bank. 3. Implement erosion control measures, including native seed, straw mulch, and coir matting on stream banks. 4. Plant trees and shrubs for long -term stabilization along the 170' section of channel using shrub species beneficial to wildlife. 5. Remove existing crossings and construct a ford for mowing access. Buck Creek: Lay back about 54 feet of right bank of Buck Creek to a 2:1 slope to reduce erosion. Road Access: Waterbar lower 300 feet of the road accessing the site. Site 2: Site 3: Construct a log vane in Buck Creek to reduce erosion of right bank and improve pool habitat. Construct a log vane and a bankfull bench in Little Buck Creek to reduce erosion of the right bank. All exposed soil would be seeded, mulched, and planted with live stakes and/or potted native vegetation. 1. Jurisdictional Determinations 4a.

Impact Justification and Mitigation 1. Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Temporarily increases in turbidity are likely from the work during construction. Potential adverse impacts would be avoided by minimizing excessive excavation and adhering to the State turbidity standard. Stream work is expected to be completed over a two week period. b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. A. Minimize the area and degree of soil disturbance that reduces infiltration capacity and permeability, and destroys protective forest floor and ground cover. B. All hazardous materials will be stored outside of flood -prone areas and surrounded with sediment fence to reduce the risk of materials reaching the river. C. Work activities would not be scheduled on rainy days. D. Heavy Equipment Operation. 1. All equipment shall be cleaned before entering the project area and stream, so as to reduce the risk of fine grained sediment and oils and grease from entering the stream. This would also reduce the risk of invasive weed spread onto the Forest. 2. Do not operate on wet soils when they are most susceptible to damage and erosion. 3. Operate heavy equipment on slopes less than 12 percent so as to reduce the risk of soil erosion. Avoid operating heavy equipment on over - hanging stream banks. 4. Move large woody debris in a manner that minimizes disturbance of the forest floor, exposure of mineral soil, or degradation of stream bank stability. E. Install sediment fence to trap potential sediment. Stabilize any disturbed area at the end of each workday. F. Re- vegetate exposed soils as soon as possible to take advantage of the loose soil conditions for seeding. 1. Exposed soil will be covered with straw mulch or erosion control matting at the end of the project. Matting will be secured in place with stakes and live stakes where conditions allow. 2. Temporary seeding will occur on all bare soil within five days of ground disturbing activities to provide long -term erosion control. 3. Stabilize channel banks with a native seed mix as work is completed. G. Do not move sediment trap devices until the vegetation in the disturbed areas has been established. H. During on -going operations inspect the site frequently; inspect occasionally during inactive periods. 1. Check for potentially damaging or failing situations that may cause unacceptable water quality impacts. 2. Correct failing situations as soon as practical. I. Conduct visual inspections of Buck Creek, Little Buck Creek, and the tributary while the work is being conducted to maintain acceptable turbidity levels. Use a skilled heavy equipment operator, trained in stream restoration and construction of in- stream structures. Instruct the operator to minimize disturbance to the streambed. 2.

BAIL visor USDA iW OW America's Working Forests - Caring Every Day in Every Way Printed on Recycled Paper ` O. United States Department of Agriculture Forest rvice Southern Region Decision Notice September 2012 and Finding of No Significant Impact Buckwheat Nantahala Ranger District Nantahala National Forest Macon County, North Carolina Buckwheat Decision Notice and Finding of No Significant Impact Buckwheat USDA Forest Service Nantahala Ranger District, Nantahala National Forest Macon County, North Carolina Decision and Rationale Decision Based upon my review of the alternatives, I have decided to select Alternative B of the Buckwheat Environmental Assessment (August 2012 EA). The Selected Alternative will: Regenerate approximately 173 acres in 11 separate stands using a two -aged method of regeneration. In the two -age method a new stand is regenerated while leaving a sparse overstory of trees that creates a second age class to the next rotation. Enough of the mature stand is removed to ensure that enough light reaches the forest floor to sustain growth and development of the new stand. Approximately 20 square feet of basal area per acre is left. Den trees and hard mast producing trees are the favored leave trees. Logging in all units would be accomplished by using conventional ground -based systems that skids the logs on the ground to a designated landing. Waterbar and seed skid trails, landings, and roads with an appropriate seed mixture following completion of logging activities. After harvesting, conduct site preparation for natural regeneration by chainsaw felling of residual nonmerchantable woody vegetation. Maintain the landings and roads as wildlife openings. At least two growing seasons prior to harvesting stands 8 -24, 19 -36, 19 -37, 22 -32, and 78 -37 (totaling about 85 acres), cut individual grape and smoke vines in these stands, then spray the cut surfaces with tripclopyr amine herbicide mixed 50/50 in water, or treat them with triclopyr ester /mineral oil in a backpack streamline spray. The vine control work is needed in order to prevent prolific growth from existing vines immediately after units are harvested. The objective is to reduce grapevine and smokevine competition to newly - regenerating trees, not to eliminate vines from the stands. In each stand, existing grape arbors will be left, up to V2 acre per 10 acres. After the first growing season, conduct timber stand improvement in all the newly- regenerated stands (about 173 acres) by controlling undesirable reproduction on stump sprouts (stump sprout clumps only — no single stems) of red maple, striped maple, silverbell, sourwood, dogwood, yellow poplar, and blackgum and individual grape and smoke vines as needed. Accomplish this work by backpack streamline spray application of triclopyr ester and imazypr mixed in mineral oil. Conduct contract slash -down work totaling 38 acres in stands 80 -16, 80 -17, and 80 -18, removing most of the over -story vegetation except for a few leave trees (15 -20 square feet of residual basal area) to simulate a two -aged regeneration harvest area. Follow the slash - down with a hot prescribed burn to accomplish site preparation. Plant the areas with pitch pine seedlings on a ten foot by twelve foot spacing. Use triclopyr herbicide, mixed in a 20% solution with mineral oil, up to four times as needed (in the early years subsequent to new stand establishment), to release the new seedlings from competing faster growing brushy vegetation and vines. This work may be necessary to allow time for the newly- established seedlings to outcompete faster - growing, brushy vegetation. Conduct slashing treatments followed by planting northern red oak seedlings on a ten foot by twelve foot spacing to ensure the survival of 300 oaks per acre on eight acres in stand 18 -37. Use triclopyr herbicide, mixed in a 20% solution with mineral oil, up to four times as needed (in the early years subsequent to new stand establishment), to release the new seedlings from competing faster growing brushy vegetation and vines. This work may be necessary to allow time for the newly- established seedlings to outcompete faster - growing, brushy vegetation. • Plant oak and /or blight resistant American chestnut seedlings in regeneration areas depending on need Decision Notice & Finding of No Significant Impact 2 Buckwheat and seedling availability. Prior) to planting, conduct pre - harvest site preparation in the selected locations using an appropriate herbicide ( triclopyr or glyphosate). After planting, conduct herbicide release at the planted locations as needed in each of several (up to five) follow -up years. The planted sites would be evaluated by Nantahala district personnel for seedling survival and competitive performance. While oak planting and post - planting herbicide treatments are not normally needed, they are approved should the need arise. Continue the prescribed fire program already established for the Buster Vinson unit (114 acres) and initiate a prescribed fire program on the Orchard unit (231 acres). These prescribed burns are for the purpose of wildlife habitat improvement and fuels reduction by reducing the amount of dead fuels on the ground and encouraging the growth of new young grasses and forbs for a source of wildlife food. They are low to moderate understory burns and would consume much of the forest floor litter but not the underlying duff. • Spray saplings in harvest unit skid trails (postharvest) with triclopyr 4E to lengthen the time that grasses occupy the skid trails, which produces more golden winged warbler habitat over time. • Disc, burn, and apply herbicide to all existing wildlife openings in the area that are in poor condition. Follow this treatment with the seeding and establishment of new grasses and forbs in an appropriate wildlife seed mixture. • Conduct treatments for watershed habitat improvement at Buck Creek and one of its unnamed tributaries. • Restore natural hydrological function and plant species diversity in nine areas of riparian flats along area streams totaling 74 acres. Restore surface flow patterns by recontouring old roadbeds. Shrubs and some small trees would be removed by cutting with hand - tools. Stumps of the cut vegetation would be sprayed with glyphosate or triclopyr herbicide to inhibit sprouting. • Control invasive species by spraying a triclopyr or glyphosate herbicide solution along all system roadsides. This treatment would be applied as many tunes as necessary. • Conduct roadside thinning along all existing FS system roads for approximately 15 -30 feet on each side. This is for the purpose of increasing sunlight to the roads and reducing the drying time of water on the road surfaces. Design Criteria Design criteria are outlined in the EA (Section 1.2, Chapter 1). In summary, the design criteria include: Proposed actions would meet the Partial Retention Visual Quality Objective (VQO) (LRMP Amendment 5 pages III- 79 -83) in the MA 2 and 4 parts of the project area. Direction for the Partial Retention VQO is for management activities to be visually subordinate to the characteristic landscape and to meet the VQO within two growing seasons after treatment. The proposal would follow standards in LRMP Amendment 10 (USDA Forest Service, 2000 and as revised in 2010) to minimize the risk of incidental take and conserve habitat for the Indiana Bat. It would comply with the terms and conditions listed in the U.S. Fish and Wildlife Service's Biological Opinion (B.O., April 2000). Retain as many snags and den trees as practicable. Designate and retain living residual trees in the vicinity of one third of all large ( >12 inches dbh) snags with exfoliating bark to provide them with partial shade and some protection from windthrow. Limit openings in the upper canopy to single tree gaps within 30 feet each side of intermittent streams, with at least 75 feet distance between openings. Leave up to ten well- formed dogwood, serviceberry, and other soft -mast producers per acre during site preparation. • A clump of trees would be left to protect the seep in stand 8 -17. Brushy edges of 50 -100 ft around existing wildlife openings will be established by heavy thinning or 2- aged regeneration depending on site conditions. In the Buster Vinson prescribed burn, there are three rock outcrops suitable for the green salamander, a NFsNC forest concern species. Green salamanders were found in one of the rock outcrops. Forest Service records show that this area has been burned two times in the past. One rock outcrop is located in a drain and is very moist. All three areas will be burned under low to moderate fire conditions and receive a backing fire so as to retain existing shade conditions. • Use brush barriers, silt fence, or hay bales to prevent visible sediment from entering streamcourses as Decision Notice & Finding of No Significant Impact 3 Buckwheat needed. Revegetate all exposed cut and fill slopes within 30 days of initial disturbance. Revegetate and /or mulch disturbed soil at stream crossings the same day. Restrict operations to periods of dry weather. Comply with the forest practices guidelines and standards in the North Carolina Forest Practices Guidelines Related to Water Quality (BMPs). Apply herbicides according to labeling and site - specific analysis; all formulations and additives must be registered with EPA and approved for Forest Service use. Use application rates at or below those listed as typical rates in the Record of Decision for the Final Environmental Assessment on Vegetation Management in the Appalachian Mountains (ROD, FEIS -Veg. Mgmt.); use selective rather than broadcast applications. Forest Service supervisors and contract representatives must be certified pesticide applicators. Sign treated areas in accordance with FSH 7109.11. Application would be consistent with USDA Forest Service herbicide risk assessments (USDA Forest Service 2007a). • Apply no herbicides within 100 feet of public or domestic water sources; those not having an aquatic label will not be applied within 30 feet of perennial or intermittent streams. Mix herbicides at the District work center and dispense into application equipment on National Forest land at least 100 feet from surface water. In addition to the above measures, apply all standards and guidelines for the appropriate MAs, as found in the LRMP, as amended. Also, apply all 99 mitigating measures found in the ROD, FEIS -Veg. Mgmt., and incorporated in the LRMP by Amendment #2 in July 1989, as needed Best Available Science My decision is based on a review of the project record that shows a thorough review of relevant scientific information, a consideration of responsible opposing views, and the acknowledgment of incomplete or unavailable information, scientific uncertainty, and risk pursuant to 40 CFR 1502.9(b), 1502.22, and 1502.24. Rationale The purpose and need for the proposal is disclosed in Section 1.2, Chapter 1 and is to improve the existing condition of the following: wildlife habitat, tree species diversity, timber resources, forest health, watershed conditions, recreational safety and access, and riparian areas within the Buckwheat Project area, in accordance with the Forest Plan goals, objectives and direction. The proposed activities move this vicinity of the Forest toward the desired future conditions established in the Forest Plan. In addition, the projects in the alternative will go towards meeting restoration goals for the Nantahala and Pisgah National Forests (see Section 1.2.3 EA). Altefnative B best meets the purpose and need and restoration goals as follows: Direction in the Forest Plan reads, in part, to "Assure a regular and sustained flow of habitats across the Forests through space and time for diversity and viability of plant and animal populations." The proposed harvest activities would accomplish the need to increase early successional habitat by increasing the percentage of young forest. Harvest activities will contribute to mixed ages of stands throughout the project area. • Silvicultural treatments will prepare and regenerate harvested areas for the development of future stands, and thinning and release treatments to improve tree growth and promote development of young trees. • Post- and pre - harvest regeneration and release treatments will improve stand stocking and species composition. • Prescribed burning is needed to improve wildlife forage, provide a more open understory and midstory for wildlife species, and to reduce the dominance of shade tolerant tree species in the understory and therefore increase species diversity. • Existing wildlife food plots and linear food strips are needed to provide grass /forb habitats and shrub habitats for wildlife species requiring those habitats. The proposed activities are in accordance with Forest Plan direction to "use vegetative management practices, including commercial and noncommercial timber harvest, to accomplish fish and wildlife habitat objectives" (Forest Plan, p. III -24). Forest Plan direction is to provide at least 0.5% of Management Areas 2A and 4D in grass /forb openings. • NNIS treatments along roads and areas that extend into forest stands will contribute to restoration of viable native plan communities. In reaching my decision, I reviewed the purpose and need for the project and the alternatives considered in detail in the EA. I then carefully weighed the effects analyses of the alternatives analyzed in detail and the public comments received on the EA. The Buckwheat Interdisciplinary Team (IDT) conducted field surveys, database queries, and other localized analyses in order to Decision Notice & Finding of No Significant Impact 4 Buckwheat determine effects the alternatives considered in detail could have on the area's ecology, including threatened, endangered, and sensitive species. During their analyses, they took a hard look at past, present, and reasonably foreseeable future actions that could be combined with expected effects from the Buckwheat proposal. I believe they provided me sufficient analyses and conclusions to make a reasoned decision. I believe the Selected Alternative will move resources in the project area towards the desired future condition, achieve the purpose and need for the project, and addresses public concerns. Other Alternatives Considered In addition to the Selected Alternative B, I considered two other alternatives in detail: Alternative A — No Action, and Alternative C A comparison of these alternatives can be found in Chapter 2 of the EA. Alternative A - No Action Under Alternative A, current management plans, such as existing wildlife management, wildfire suppression, general road maintenance, and special use authorization operations would continue to guide management of the project area. I did not select this alternative for several reasons. This alternative would not have provided and improved wildlife habitat;; used herbicides to control /manage non - native invasive populations; controlled /managed competing vegetation; improved water quality and aquatic habitat; or created ESH. I believe active management is needed to move the area towards the Forest Plan's desired future condition. Alternative C Alternative C would include all of the treatments proposed in Alternative B, with the exception of two -age regeneration treatments in four areas: 8 -17 (19 acres), 19- 36 (24 acres), 22 -33 (13 acres), and 78 -37 (14 acres), producing 103 acres of early successional habitat as opposed to the 173 acres proposed under Alternative B. While Alternative B falls short of the desired condition for early successional habitat and grass /forb openings, Alternative C produces even less. Accordingly, Alternative B best meets the objectives of the Forest Plan while also increasing age class diversity. Public Involvement This proposal has been discussed at public meetings aat the Nantahala Ranger District office on October 4, 2010 and January 31, 2012. The proposal was provided the public and other agencies for comment during scoping that was initiated on February 16, 2012. A formal 30-day Notice and Comment period began on July 7, 2012, and ended on August 6, 2012. A total of four members of the public provided written comments on the EA. I carefully reviewed and weighed all comments received during the development of this decision and used them to guide my decision. Comments are addressed in the EA (see Response to Comments, Appendix D Chapter 5). Finding of No Significant Impact After considering the environmental effects described in the EA, I have determined that these actions will not have a significant effect on the quality of the human environment considering the context and intensity of impacts (40 CFR 1508.27). Thus, an environmental impact statement will not be prepared. I base by finding on the following: 1. My finding of no significant environmental effects is not biased by the beneficial effects of the action (Chapter 3). 2. There will be no significant effects on public health and safety and implementation will be in accordance with project design features (Section 1.2.3, Chapter 1; Chapter 3). 3. There will be no significant effects on unique characteristics of the area, because there are no park lands, prime farmlands, wetlands, wild and scenic rivers, or ecologically critical areas in the project area, nor would it violate local law or requirements imposed for the protection of the environment (Chapter 3). 4. The effects on the quality of the human environment are not likely to be highly controversial because there is no known scientific controversy over the impacts of the project (Chapter 3). 5. We have considerable experience with the types of activities to be implemented. The effects analysis shows the effects are not uncertain, and do not involve unique or unknown risk (Chapter 3). 6. The action is not likely to establish a precedent for future actions with significant effects, because the project is site specific and effects are expected to remain localized and short-term (Chapter 3). 7. The cumulative impacts are not significant (Chapter 3). 8. The action will have no effect on districts, sites, highways, structures, or objects listed in or eligible for listing in the National Register of Historic Places (Section 3.10, Chapter 3). The action will also not cause loss or destruction of significant scientific, cultural, or historical resources (Section 3.10, Chapter 3). A heritage report was completed for this project which found that there were no archeological sites eligible for the National Register of Historic Places. The report was sent to the State Historic Preservation Office (SHPO) on June 21, 2012 and issued de facto Decision Notice & Finding of No Significant Impact 5 Buckwheat concurrence on July 23, 2012. The Tribal Historic Preservation Office (THPO) concurred with the report on July 16, 2012. 9. The June, 29, 2012, Biological Evaluation (Appendix B, Chapter 5) concluded: A. Implementation ofAlternative A, Alternative B, or Alternative C of the Buckwheat Project would have no effects to any threatened or endangered aquatic species because none occur within the aquatic analysis areas and the effects of the proposed actions would dissipate prior to reaching habitats suitable for these species. B. Implementation ofAlternative A, Alternative B, or Alternative C of the Buckwheat Project would have no effects to any threatened or endangered plant species because none were located within the proposed activity areas. C. Implementation of Alternative A, Alternative B, or Alternative C of the Buckwheat Project is not likely to adversely affect the Indiana bat (Myotis sodahs) because all standards and guides for the protection of this species, as listed in Amendment 10 of the Land and Resources Management Plan, will be followed. The project will have no effect on any other federally proposed or listed terrestrial animal species. Furthermore, implementation of Alternative A, Alternative B, orAlternative C would have no effects to any other threatened or endangered terrestrial wildlife species because none occur within the analysis areas. D. The USDI Fish and Wildlife Service concurred with the determinations of effect in a letter dated July 12, 2012. 10. The action will not violate Federal, State, or local laws or requirements for the protection of the environment. Applicable laws and regulations were considered in the EA. The action is consistent with the Nantahala and Pisgah National Forests Land and Resource Management Plan Amendment 5. Findings Required by Other Laws and Regulations My decision to implement the Selected Alternative is consistent with the intent of the long -term goals and objectives listed on pages III -1 and III -2 of Forest Plan Amendment 5. The project was designed to meet land /s/ Michael L. Wilkins MICHAEL WILKINS Nantahala District Ranger and resource management plan standards and incorporates appropriate land and resource management plan guidelines.

Site #1: Site #1 is located off a spur road from FSR 4591 on a tributary to Buck Creek (GPS point N35.127038, W083.239332). This area was likely farmed in the past and the stream was channelized down to Buck Creek for almost 200 feet. The area is currently a maintained wildlife field. One old woods road contains a non - functional wooden culvert. The wildlife field contains a small unnamed tributary of Buck Creek. The stream banks are steep and eroding into the tributary (Photo 1) and into Buck Creek (Figure 2). In addition to the tributary, a section of Buck Buck Creek, Macon County, Watershed Improvement Project Page 1 Creek channel bank in the wildlife opening is eroding where fill material was placed historically (Photo 2).

The goals and objectives of this project are to improve the health of the stream ecosystem by improving channel stability and habitat quality, along with improving riparian and streamside vegetation conditions. This will be accomplished with the construction of instream structures using trees found on site fashioned to protect eroded stream banks and create high quality aquatic habitat features. The desired condition is to have high quality riparian areas and aquatic habitat features that maintain hydrologic function, enhance stream stability, and minimize erosion. The proposed action is needed at this time, at these locations, because taking no action would lead to further erosion and sedimentation which, in turn, would cause further damage to aquatic habitat and the maintenance of designated uses.
