These native species include: bog birch, <br />canada blue joint grass, nightshade, smartweed, arrowhead, swamp milkweed, leather leaf, wool- <br />grass, giant manna grass, willow and sedge species. It currently contains reed canary grass and <br />glossy buckthorn, invasive species that are quickly reducing the ecological integrity of the basin <br />by shading and out competing native species. <br />This basin extends beyond the park boundary to the south and east. Beyond the park boundary is <br />over two -acres of shallow marsh dominated by cattails. A boardwalk cuts through the wetland at <br />an angle and offers excellent viewing opportunities to the public. A green heron and songbirds, <br />such as goldfinch, were observed the day of the inventory. <br />An aggressive maintenance program to reduce glossy buckthorn and reed canary grass would <br />reduce shading and competition from these invasive species and allow the remnant native plant <br />species an opportunity to re- establish. <br />City of Roseville 75 <br />Parks Natural Resource Management <br />
