Mounds View Ardan Park Ponds <br /> Mowed Nonnative Grasses with Scattered Trees - Desired Future Conditions <br /> Overview <br /> NATIVE GROUND COVER <br /> Vegetation o <br /> Layer <br /> Cover(/o) Representative Plant Species <br /> Canopy variable Existing trees, such as black walnut, river birch, and crabapple <br /> Prairie and savanna species such as little bluestem, sideoats grama, <br /> Herbaceous prairie dropseed, plains oval sedge, gray-headed coneflower, Virginia <br /> (Ground) 100 mountain mint, butterfly milkweed, prairie coreopsis, and many other <br /> native grasses, sedges, and forbs <br /> 4 Vegetation Restoration Activities & Cost Estimates <br /> 4.1 Activity Types <br /> The goals and objectives outlined above for each cover type can be accomplished by implementing best <br /> management practices for ecological restoration and vegetation management. The activities described <br /> below are most effective when integrated. For example, invasive plant control should be combined with <br /> seeding/planting to replace the invasive plant cover with desirable vegetation. The following sections <br /> describe activities anticipated for vegetation restoration and maintenance around the ponds. <br /> 4.1.1 TREE REMOVAL <br /> Tree removal is recommended for invasive, nonnative trees and for select native trees in the areas <br /> recommended for Lowland Hardwoods and Pin Oak—Bur Oak Woodland restoration. Tree removals <br /> should be planned for dormant seasons with frozen ground conditions to minimize ground disturbance <br /> and impacts to understory vegetation. Stumps should be treated with herbicide specifically proven to kill <br /> the root systems and prevent re-sprouts of target trees. <br /> Tree removal bids can be solicited on a cost per acre or on a per-tree basis, depending upon the scale of <br /> a restoration project. For the relatively small scale of work at Ardan Park Ponds, conducting an inventory <br /> of trees slated for removal and field marking each tree will enable development of more detailed bid <br /> specifications for more accurate contractor pricing. <br /> 4.1.2 INVASIVE SHRUB CONTROL <br /> Invasive shrub control will primarily involve common buckthorn, but glossy buckthorn, Tartarian <br /> honeysuckle, and shrub/sapling-sized invasive trees should be included in this activity as well. Buckthorn <br /> ranges in size from seedlings to trees that are over 3-4 inches in diameter at the park. <br /> Project <br /> ® Number: <br /> 193806462 12 <br />
