A hallmark of ACD's natural resource work has included the stabilization of eroding riverbanks and the enhancement of native vegetation in adjacent riparian and floodplain areas. These activities improve water quality in the river and habitat quality along it. Included in the goals of our Phase 2 grant for Rum River habitat enhancement through the Outdoor Heritage Fund of the Clean Water Land and Legacy Amendment is the improvement of in-stream habitat in the Rum River channel. This is a new endeavor for ACD that presents an exciting opportunity to expand our work and our partnerships within the Rum River Corridor.

Though we are over a century removed from the widening and scouring of the Rum River by the millions of logs cut during the Minnesota timber boom, the effects of that industry still remain. Rivers used as log arteries were made wider and more consistent to ensure the smooth sailing of logs downstream. In more modern times, towns piped rain water directly to the river from impervious areas via stormwater conveyance systems. These rapid spikes in water input during storms exacerbate bank erosion, down-cutting, and sedimentation in the river at rates far beyond what was natural. 

Due to this historical usage of the Rum River as a conveyance tool for wood and stormwater, habitat for fish, invertebrates, mussels, and other aquatic life remains lacking and out of balance. In the coming years we will be partnering with Anoka County Parks, DNR Fisheries, The Nature Conservancy and others to identify and enhance missing or deficient in-stream habitat. Secondarily, we will look for enhancement opportunities for game fish habitat near publicly accessible shorelines to improve access to quality shore fishing.

During a recent site visit to explore wetland restoration opportunities, ACD staff came across a fantastic example of beavers' "engineering" skills in action! A series of three beaver dams, located near the outfall of a Rum River tributary, were effectively slowing and spreading the stream's flow into the surrounding floodplain wetlands. Healthy connections between streams and their floodplains provide numerous water quality and habitat benefits, and in this case those benefits also extend to the Rum River immediately downstream.

Many streams in modified landscapes take on excess water from artificial drainage features like ditches and storm pipes. Over time and especially during extreme precipitation events, these higher volumes of water often increase erosion within the stream, which can lead to the straightening and downward-cutting ("downcutting") of the stream channel and, as a result, the disconnection of the stream from its floodplain (see the figures below, produced by American Rivers). 

Floodplain reconnection efforts are an increasing priority amongst many conservation organizations, but they can be costly and complicated – particularly if development has occurred within the floodplain. However, in areas where streams have room to spill into their floodplains without causing damage, allowing and even promoting beaver activity can be a cost effective way to help restore riparian corridors.

Plant species that are "native" to a local area (i.e., grow there naturally) provide necessary food and habitat for pollinators and enhance soil and water quality. Outdoor spaces that are in covered in turf provide very few benefits to pollinators or the environment, so frequent pockets of natural spaces are critical in developed areas. We recently converted part of our office property from an area that was annoying to mow into beneficial pollinator habitat! Here's how we did it:

In early summer, we used "sheet mulching" to kill off the grass and weeds. If you can plan to have a couple of months before planting, this is an easy method to prepare a site without using herbicides. The future garden space was fully covered in cardboard sourced from our local recycling facility and then covered with a couple inches of mulch. This effectively smothered existing weeds.

It will be exciting to watch these new plants grow over the coming year to create a beautiful spot that will support some of our essential pollinator species in Anoka County.

You can also follow these steps to convert areas of your property that may not get much traffic or are hard to mow into a space that will benefit everyone! 

The Anoka Conservation District has completed work with six landowners on Lake George to correct shoreline erosion and install native plant buffers. 483 linear feet of shoreline were treated with rock rip rap, coconut fiber biologs, shoreline plantings, or other techniques. The result is 5.9 fewer pounds of phosphorus and 4.8 fewer tons of sediment entering the lake each year.

Lake George water quality is a priority. The lake is heavily used by the public due to a large county park and many homes on its shores, and good water quality. That water quality has been experiencing a slow decline over time. Projects such as these help maintain water quality and also add near-shore habitat that benefits fish and other wildlife. The recently installed projects are further intended to be demonstrations of lake-friendly landscaping for other shoreline homeowners. 

Anoka Conservation District recently submitted two proposals, HRE07 Rum River Corridor Fish and Wildlife Habitat Enhancement – Phase 2 and HA02 Anoka Sand Plain Habitat Conservation – Phase 8 to the Lessard-Sams Outdoor Heritage Council ML 2023 Request for Funding. The proposed activities will enhance aquatic and terrestrial habitat in Anoka County and collaborate with Partners in the Rum River Corridor and the Anoka Sand Plain Ecoregion.  

HRE07 Rum River Corridor Fish and Wildlife Habitat Enhancement – Phase 2
$3.5M request ($3M for Anoka County) includes:

• Streambank and in-channel stabilization (2,200 linear feet);
• In-stream fish habitat with a focus on game fish (1,200 linear feet); and
• Riparian forest, wetland, and prairie enhancement in the Shoreland Zone (118 acres) including wild rice habitat on tribal lands.

Partners:

• Anoka, Isanti and Mille Lacs SWCDs
• Anoka and Isanti Counties
• Upper and Lower Rum River WMOs
• The Nature Conservancy
• Mille Lacs Band of Ojibwe

HA02 Anoka Sand Plain Habitat Conservation – Phase 8
$8.9M request ($2.15M for ACD) includes:

• Conservation easements (540 acres)
• Habitat restoration and enhancement (1,736 acres and 2,200 linear feet of shoreline)
• Rare plant rescue program

BWSR awarded ACD $40,000 for the Habitat Enhancement Landscape Pilot Program. ACD, Anoka County Parks, City of Blaine and City of Fridley identified project sites to create species rich, diverse prairies. There are 12 prairies identified in Anoka County Parks land with low forb diversity within the Rusty Patched Bumble Bee priority area that will be enhanced. Turf to prairie conversion will occur on a total of 4.75 acres at Fridley Commons Park, Blaine Laddie Lake, Coon Rapids Dam, Rice Creek West Regional Trail and Bunker Regional Park. These projects range from 0.25 to 1.5 acres and will be forb-rich.

Financial and Technical Assistance

Because environmental benefits produced through conservation practices typically extend beyond the bounds of your property, conservation projects such as lakeshore restorations, riverbank stabilizations, and best management practices for urban or agricultural stormwater runoff may qualify for financial or technical assistance. Seeking out and applying for these opportunities early will help you get a strong head start on spring and summer projects.

Anoka Conservation District has been working with the City of Anoka and Mississippi Park Connection to create a more resilient landscape at Kings Island. Efforts have begun to remove invasive buckthorn from the island to allow space and light for native plant regeneration. Invasive emerald ash borer (EAB) infestations that kill ash trees have been detected throughout the Metro region and near Kings Island. Approximately 50% of Kings Island canopy is ash (green, black or white ash) so a loss of ash would have a great impact on the habitat on Kings Island. Surveys have and will continue to be conducted to monitor for the presence of EAB. To prepare for the loss of ash trees and create a more resilient landscape at Kings Island, a diversity of tree and shrubs were planted by volunteers. Species planted include Nannyberry (Viburnum lentago), Red-oiser Dogwood (Cornus sericea), Swamp white oak (Quercus bicolor), Butternut (Juglans cinerea), Cottonwood (Populus deltoids), Hackberry (Celtis occidentalis), Highbush Cranberry (Viburnum trilobum), and Sycamore (Platanus occidentalis) a tree with a more southern range. More efforts are needed to control buckthorn and create diversity for a more resilient landscape at Kings Island.
