wildlife, rare plant communities or ecosystems. To avoid indirect impacts to water quality, appropriate erosion and sediment control best management practices will be implemented during the construction phase and preservation of 25 -foot wetland buffers will occur to the greatest extent possible. Phase 2 construction and grading activities may affect 15.3 acres of forest for additional campground space and gravel access roads. Phase 2 will not result in impacts to fish, wildlife, rare plant communities or ecosystems. To avoid indirect impacts to water quality, appropriate erosion and sediment control best management practices will be implemented during the construction phase and preservation of 25 -foot wetland buffers will occur to the greatest extent possible. Aiding the spread of invasive species or noxious weeds will be avoided by implementing BMPs. Avoidance efforts will include the following BMPs: using weed -free mulch when applicable; proper disposal of soils disturbed by the Project and known to contain a seed base of a prohibited invasive species and noxious weeds; and application of a native seed mix soon after grading or construction has been completed to avoid presenting colonization opportunities. d. Identify measures that will be taken to avoid, minimize, or mitigate adverse effects to fish, wildlife, plant communities, and sensitive ecological resources. Wetland habitat will be protected by establishing vegetated buffers where practicable and installing silt fence and other erosions control BMPs as appropriate. The MnDNR has provided a general list of recommendations for avoiding and minimizing short- term construction impacts to Blanding's turtle (see Appendix Q. The following MnDNR recommendations are part of the Project's design to avoid short-term construction impacts to the Blanding's turtle: • If found on site, turtles that are in imminent danger will be moved, by hand, out of harm's way. Turtles that are not in imminent danger will be left undisturbed. • Silt fencing will be established to exclude turtles from construction areas near wetland habitats with the potential to support Blanding's turtles. The silt fencing will be removed after the area has been vegetated. • Trenches created during construction will be checked for turtles prior to being backfilled. • Graded areas will be revegetated with native grasses and forbs where practicable. • Terrain will be left with as much natural contour as possible. In addition, MnDNR provided the Project with a Blanding's turtle flyer to be distributed to contractors to inform them of the turtle's potential presence and provide typical construction BMPs. This flyer will be provided to applicable contractors. 14. Historic properties: Describe any historic structures, archeological sites, and/or traditional cultural properties on or in close proximity to the site. Include: 1) historic designations, 2) known artifact areas, and 3) Page 18
