Patches of problem species that represent more than 5% cover of wetland or upland areas should be.:spot mowed to prevent seed set and treated with :herbicide at .art appropriate time.. 4: If possible and reasonably feasible, a: controlled burn should be conducted once between thethird and fifth year.. Year 6 (and beyond) Maintenance 1.

If possible and reasonably feasible, a controlled burrs should be:conducted every three to five years. 3. WETLAND REPLACEMENT STANDARDS Total credit to meet replacement :requirements is 4:6676 acres. The goal. of the Wetland Replacement Plan (created wetlands and associated. upland buffer) is to createlenhance over 1.0522 acres: of functioning mitigation wetland with "Medinin Quality rated plant communities. as defined by MnR.AM, along with 1.41.0 acres of upland buffer establishment/preservation with a predominance of native, non-invasive vegetation. All credit is expected to be granted once performance requirements are met. NOTE: For outlot upland areas, the goal is to establish an upland. plant community with a. predominance of native non-invasive species;. replacement area performance standards and monitoring criteria do not apply.. For the replacement areas,. the success of management efforts will be determined by comparing the observed (C) development of the vegetative communities to expected (E) performance standards for each monitoring year. The replacement plan will. be considered acceptable when the observed conditions are consistent with the performance standards as outlined in the. table on the last page of this document. Certification. of the replacement plan and an end -to -monitoring may be granted when the fallowing performance criteria are met. Tar,aet Veuetation Target Vegetation shall be comprised.of three components: (l) minimum aerial coverage of native/non-invasive species, (2) number of native plant species (species richness), and (3) percent of.all plant species that are FAC indicator status or wetter. Per MaMM; a Medium. quality rated shallow marsh plant community will,have at least 2 species of native aquatic plants (FACW or wetter) as dominants; and/or purple. loosestrife comprises 20 to:5il percent cover; and /or cattails comprise 40 to 85 percent cover. 4
