invasive plant species including, but not limited to, diffuse knapweed, musk thistle, or <br />Dalmatian toadflax until reclamation of this area is deemed complete. <br />Remaining Actively Filled Areas (5.3 Acres) <br />The remaining 5.3 acres area is still being actively reclaimed with fill and grading <br />operations. Continued filling of the mine and associated grading will keep much of the <br />area free of invasive plant species. Application of herbicide in late summer/early fall on <br />dense patches of invasive plant species not within areas of active filling and grading can <br />occur as needed to reduce the seed source for adjacent lands. Exact timing of herbicide <br />depends on growth of rosettes in late summer/early fall, typically coinciding with late <br />growing season precipitation. <br />Final grading and seeding of the mine, after completion of fill activities, will require <br />seeding of appropriate native plant species. The seeded area will require periodic <br />management, on an as needed basis (likely annual for three to five years post seeding) of <br />invasive plant species such as clipping and bagging flowers and herbicide treatments <br />within the seeded area until reclamation of this area is deemed complete. It is also <br />recommended that the newly seeded areas be temporarily excluded from cattle grazing <br />through the use of fences until vegetation is established. This will ensure seeded areas <br />develop suitable competition, reducing occupancy of invasive plant species until <br />reclamation activities are deemed successful. <br />Prepared by: <br />Eric W.
