The site is looking very good after its first
season. The initial plan called for the site to be prepared for planting
fall 2003, which would have allowed for a chemical treatment to rid the new
topsoil of invasive weeds. The site preparation could not be completed
until late spring 2004, so chemical treatment was not possible as it would have
delayed planting past the optimum dates. The result was invasive mustards,
lambs quarters, pigweed, ragweed and smartweeds. These were controlled by
a two-step process. First, "weed wicks" were used to apply a Glyphosate
herbicide (RODEO) in areas where the weeds were significantly taller than the
native plants. Second, Minnesota Conservation Corps (MCC) was hired to
hand weed the majority of the site. Volunteers from the Northwest Juvenile
Center Satellite Home also helped with the hand weeding. Sentence to Serve
was not able to fit the weeding into their schedule this year, but we hope to
fit it in next summer. A large black fence was chosen by MN DOT to
match the fence portions of the nearby Mississippi River inlet bridge.
This fence separates the steep portions of the site from the adjacent bike path.
Fencing was not installed around three of the four "lookout" areas due to
excessive settling of the ground and subsequent lowering of the fence pilings.
When the ground has finished settling, these areas will be built up, the pilings
extended, the fencing installed and the affected sections replanted.

The southern end of the site has a more gentle slope, and thus did not need the riprap toe. There has been some additional erosion due to people pulling their boats up and trampling the native plantings. |

Some species were chosen for their stabilization abilities, others for their showy flowers and aesthetic effect. The pink forb, smartweed, is a native plant that volunteered to the site. Much of it was pulled from the site during weeding to allow the other natives to become established. |

This shows one of the mixed areas of the site. These areas were planted at one-foot intervals with a mixture of 40% grass, 60% forbs. |

The aster is a late season bloomer, making it very attractive to butterflies and other insects. |

Anise hyssop is a very attractive native forb that blooms from mid-summer to frost. It is a favorite of butterflies, bees and hummingbirds.

Black Eyed Susan is another attractive native forb that blooms from mid-summer to frost. It is used by butterflies and birds. Over time, it will likely disappear from the site as the other native forbs become established. |

Each species of forb or grass was featured by planting it in a specific area of high concentration in addition to being a part of the intermediary mixed areas. |
