Land Protection

ACD has collaborated with BWSR's RIM program to establish conservation easements to permanently protect, restore, and manage natural resources on private lands. Land protection has many benefits including protecting water quality, habitat, creating conservation corridors, and supporting climate resiliency.  

In 2023, two new conservation easements were established along the Rum River. They are adjacent to a conservation easement that was established in 2022 through the Rum RIM program and across the river from a DNR Conservation Easement. These conservation easements create a block of protected land totalling 183.5 acres along 10,960 feet of shoreline. The Gamm, Stenson-Gamm, St. Francis Land Development, and MN DNR Conservation Easement create an additional habitat core with functioning ecosystems and enhance habitat in the Rum River corridor.

2023 ACD Technical Assistance Summary

ACD staff provide technical assistance for a wide-variety of projects each year. Many of the requests for assistance come directly from landowners interested in improving natural resources on their individual properties. Technical assistance is also provided for projects in collaboration with county, city, and watershed entity partners. The table below summarizes 2023 technical assistance provided by ACD staff. 

Assistance usually begins with a site consultation. Consultations typically include a conversation with the landowner, desktop review of the site using GIS mapping software and available data sets, and a site visit to discuss options. If the landowner is interested in pursuing a project, ACD can provide design and installation oversight services. Maintenance guidance is also provided for previously installed projects.

Managing Emerald Ash Borer and Oak Wilt in Anoka County

Emerald Ash Borer (EAB) is an invasive insect that has killed millions of Ash trees throughout North America. Since 2009, EAB has been detected in 46 counties in Minnesota, including Anoka County. MN is home to over 1 billion Ash trees, all of which are vulnerable to EAB infection.

Trees affected by EAB dry out and rot quickly, creating public safety hazards. If allowed to decay, these conditions can cause trees to become dangerous to manage. Removing ash trees in high-traffic areas including along public trails and neighborhood streets is a top safety priority. Learn more about Emerald Ash Borer on the ACD Website.

Oak Wilt is a fungal disease that affects all species of oak trees. It is spread by sap beetles and through the tree's root systems. The disease affects Oak species differently; it can kill Red Oak trees in 2-3 months whereas White Oaks can live up to 20 years after becoming infested. It's important to know the signs of Oak Wilt to prevent further forest damage. Learn more about Oak Wilt on the ACD Website. 

 Help Stop the Spread!

Avoid cutting and pruning Ash trees from May 1 - September 31 as EAB insects are most active during this time. Do not transport firewood offsite from where it was collected. The Twin Cities metro and much of Eastern, MN is within an EAB quarantine zone and transporting firewood out of these areas risks spreading EAB.

Avoid cutting and pruning Oak trees from April 1 through July 31 as sap beetles are most active during this time. Treat spring and summer tree wounds with a water based paint or pruning wound sealer to avoid attracting sap beetles. Do not transport firewood off the site where it was collected. The Twin Cities metro and much of east central Minnesota is infested with Oak Wilt. Transporting firewood out of this area risks spreading this forest disease.

The unseasonably warm winter extends the 'don't prune' window and it probably starts in March for 2024. 

 ACD was a recipient of the MN Department of Natural Resources ReLeaf Community Forestry Grant to help efforts to manage Oak Wilt and EAB in Anoka County. A variety of tree species will replace those affected by Oak Wilt in the Anoka Nature Preserve (ANP), including treating Common buckthorn in 2024-25 to free up space for new trees to be planted in 2026. Ash trees at Kings Island in the City of Anoka will be removed in early 2024 and new trees will be planted in 2025. Planting at both of these sites will be completed with the help of volunteers. If you have interest in helping out as a volunteer, sign up here!

Golden Lake Proposed For Removal From State's Impaired Waters List

The proposed removal of Golden Lake from Minnesota's impaired waters list was highlighted in a recent Board of Water and Soil Resources (BWSR) article that underscores the importance of Clean Water Funds (CWF) for measurable water quality improvement. ACD secured two CWF grants for iron-enhanced sand filters (IESF) to reduce phosphorus reaching Golden Lake, located in Circle Pines, MN. Iron-filings mixed throughout the sand, capture phosphorus from stormwater passing through the filters. One IESF was installed in Centennial Green Park (2015) in the City of Blaine, and the other was installed in the City of Circle Pines (2019). Both projects were identified as cost-effective phosphorus reduction options in a Golden Lake stormwater retrofit analysis completed by ACD. 

The proposed delisting of Golden Lake is a testament to the hard work and collaboration by many, including ACD, the City of Blaine, the City of Circle Pines, and the Rice Creek Watershed District. Mitch Haustein, ACD's Stormwater and Shoreland Specialist, assisted with the projects and was interviewed for the article. Click here to read the full article from BWSR that also includes brief stories about proposed delistings for 6 other Twin Cities area lakes, 1 Wright County river reach, and 1 Winona County stream segment.

Emergent Vegetation Plays an Important Role in Lake Health

Emergent aquatic plants such as cattails, bulrushes, and sedges grow within the shallow margins, or "littoral zone", of most lakes in Minnesota. These plants improve water clarity as their roots stabilize the lakebed and take in nutrients. Stems and leaves provide habitat, both above and below the water, and protect shorelines against the forces of wave action. Emergent plants often grow alongside other aquatic vegetation, collectively creating diverse habitat essential to lake health. 

Any Destruction of Emergent Vegetation Requires a Permit in Minnesota - Lakeshore owners often wish to remove emergent vegetation to improve their water access. Given the important role emergent plants play in lakes, any removal of aquatic emergent vegetation requires a permit from the Department of Natural Resources. The permit process connects landowners with professionals to ensure that the extent of vegetation removal (and methods used to achieve it) minimize impacts to the lake. Learn more about aquatic plant regulations HERE.

When Does Emergent Vegetation Become Problematic? - Non-native species such as narrow-leaf and hybrid cattails often grow in dense monocultures that can outcompete native species. Habitat quality and recreation can be quickly reduced as these species spread across large areas of shallow water, but management efforts to remove them are often challenging and costly. When occurring in small clusters, these plants can still provide water quality benefits along shorelines where native emergent plants are absent. In either circumstance, any removal of a emergent plant species requires a permit.


Expectations for Living on a Lake - Aquatic vegetation is a natural and important part of lake and wetland systems. The abundance and types of plants present are largely driven by water depth and clarity. Many lakes in the north-metro are shallow (less than 15 ft. deep) or are more functionally open-water wetlands. When paired with good water quality, allowing sunlight to reach the bottom, these lakes usually contain abundant vegetation throughout. The alternative is poor water quality from disturbances such as excessive nutrient, loss of aquatic vegetation and loss of the fish and wildlife dependent on it. Learn more about shallow lake vegetation from this StoryMap produced by the Rice Creek Watershed District: Aquatic Plants: Guardians of our Shallow Lakes.

Become an SWCD Supervisor!

Minnesota's natural resources play an important role in the state's economy and high quality of life. Protecting and managing these precious natural resources is a large undertaking and takes continuous effort at the state and local level. Soil & Water Conservation Districts (SWCD's) throughout the state are governed by a five member board of supervisors elected by the citizens of the county. The SWCD board is responsible for policy development, annual plans, budgets, and more. The Anoka Conservation District will have three supervisor positions on the November 2024 ballot. These positions are four-year terms and require between 1 to 3 monthly meetings and receive modest compensation per meeting.  

The following districts in Anoka County will be up for election:

District 1 - Anoka, part of Coon Rapids, Nowthen, Oak Grove, Ramsey, St. Francis
District 4 - Portions of Blaine and Coon Rapids, all of Lexington
District 5 - Bethel, Centerville, Circle Pines, Columbus, East Bethel, Ham Lake, Lino Lakes, Linwood Township


Filing is easy but must happen between May 21 and June 4. Just go down to the County Government Center in Anoka during that time and they'll tell you what to do.

ACD Host Chainsaw Training

This past month, ACD and partner staff completed an 8 hour chainsaw safety training course. The skills and safety tips learned will be applied while clearing large buckthorn, cutting cedar trees for streambank stabilization projects, and while addressing other natural resource concerns that come our way. Winter is an ideal time to cut or trim oak and ash trees without the high risk of spreading oak wilt and emerald ash borer diseases. If you plan to cut trees on your property this season, remember the following tree felling rules:

Hazards- Survey the area to identify and remove any potential hazards.
Hinge- Create a hinge for safe and predictable felling. See an example notch here.
Escape- Have 2 escape routes at 45 degrees from your cutting direction.
Lean- Analyze the tree from all angles to ensure you understand its weight distribution and lean direction.
Plan- Have a plan to complete a safe and predictable cut. Click here to learn how to execute the bore cut.

Having the right training and equipment can spare you from serious harm when using a chainsaw. Take the time to educate yourself on proper safety equipment and risk management strategies. Safe cutting! You can read a description of the training course here or contact Logan Olson, Restoration Technician, at This email address is being protected from spambots.

Working in the Rum River to Improve Habitat

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. 

The Washburn Saw Mill on the Rum River – late 1800s Source: Anoka County Historical Society
Plunging flow off the end of a bendway weir in the Rum River creating areas of rapid and slow flow, variable water levels, a scour pool, and quiet water depositional areas. This creates variability in flows and habitats.

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.

Wildlife Management Areas: What, Where, Why

Wildlife management areas (WMAs) are part of Minnesota's outdoor recreation system and are established to protect those lands and waters that have a high potential for wildlife habitat and other compatible recreational uses. WMAs are key to:

  • protecting wildlife habitat for future generations,
  • providing citizens with opportunities for hunting, fishing and wildlife watching, and
  • promoting important wildlife-based tourism in the state.

How did WMAs get started?
Minnesota's WMA system started in 1951, when the State established its "Save the Wetlands" program to buy wetlands and other habitats from willing sellers to address the alarming loss of wildlife habitat in the state. Initiated by a handful of visionary wildlife managers, the WMA program evolved into the present-day system of WMAs.

How many WMAs are there and where are they located?
There are over 1.3 million acres of high quality habitat in about 1,500 WMAs located throughout the state, making it one of the best and largest WMA systems in the country.

How are WMAs managed?
WMAs are the backbone of DNR's wildlife management efforts in Minnesota. Much of the wildlife managers' work is directed toward protecting and enhancing wildlife habitat on WMA lands. For instance, prairie and grasslands are planted, wetlands are restored and enhanced. Prescribed burning is done to maintain grasslands, prairies, and brush lands. Forest openings and regeneration projects benefit create wildlife habitat. Different management practices are utilized for different ecotypes.

What can I do to help?
There are opportunities to volunteer at WMAs by picking up trash to assisting with seed collection and much more! For more information and locations of WMAs go to this link https://www.dnr.state.mn.us/wmas/index.html.

Pursuing Levy Authority in 2024

The elected Board of ACD is moving forward with legislation to have the ability to levy property taxes for residents of Anoka County. With the levy limits included in the bill (HF3701) and ACD's other revenue streams, the anticipated levy increase for the average single family home in 2025 through 2029 is around $0.67 per year. Why bother pursuing legislation for such a small levy? That's a long story, but here's the gist of it.

  • ACD has been around since 1946 serving the public by providing financial and technical assistance to private landowners who want to be good stewards of our lakes, stream, wetlands, drinking water, wildlife, etc.
  • ACD submits a budget to Anoka County to request funding to support our mission. The County has the option to fund all, some or none of the request.
  • ACD's requests to the County compete for limited funding against transportation, public safety, social services, economic development, and parks and recreation.
  • For 20 years, when population growth and inflation alone grew Anoka County's budget by 83%, ACD's allocation grew by 8.4%.

"So what you're saying is that if ACD gets its way, a family of four in Anoka County will have to give up one fancy cup of coffee every four years for cleaner lakes and rivers, better fishing, improved habitat for wildlife, and safer drinking water?" Well, when you put it that way…
