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! 

On a cool and cloudy May morning, ACD participated in Isanti Conservation Day, an annual event designed to teach students about natural resource stewardship. Approximately 475 fifth graders were given a chance to get outside for a morning to learn about the natural world around them, and how to protect it, by rotating through stations scattered throughout Becklin Homestead Park. ACD collected a myriad of live aquatic invertebrates from local streams to give the students a hands-on way to learn about the unseen creatures that live in their favorite water bodies.

Each group examined trays containing wriggling nymphs of mayflies, damselflies, and dragonflies, case-building caddis fly larvae, freshwater shrimp, snails, and more. They excitedly gathered around their tables to observe the activity in their trays and tallied how many kinds of invertebrates they were able to identify from a provided list. This led to discussions on what the diversity and types of creatures found in the water could tell them about river health. Looking at their lists, students learned that they could make inferences about water quality based on the pollution tolerance of the invertebrates that they found. Each session was wrapped up by sharing ideas on actions and practices that they could take to protect the health of their local rivers. The event was engaging for the fifth graders and provided them with new perspectives on how people can learn about water quality.  

Lymantria Dispar is an invasive moth formerly known by the common name Gypsy Moth. Last year, the Entomological Society of America officially changed the common name for this invasive species to the Spongy Moth. Romani people, Europe's largest ethnic group, generally consider the common name "Gypsy Moth" to contain a racial slur. The Entomological Society of America states that "while the use of an ethnic slur is enough reason to stop using a common name, the former common name was doubly inappropriate in that it linked a group of people who have been treated as pests and the targets of genocide with an invasive pest insect that remains targeted for population control and eradication, all of which combined to have dehumanizing effects for Romani people."  

The new common name for Lymantria Dispar, the spongy moth, refers to the insect's light brown, fuzzy egg masses. This new name also aligns better with other countries common name for this invasive species. This moth is known for defoliating deciduous forests while in their caterpillar form. This repeated defoliation causes stress and can leave trees vulnerable to other diseases and pests. Spongy moths were introduced to the United States from Europe in the nineteenth century. They have spread from their initial location in Massachusetts westward, in both the United States and Canada. 

Since 2004, Minnesota has been a member of the U.S. Forest Service's Slow the Spread (STS) program. Cook and Lake Counties are the only places with reproducing spongy moths in Minnesota. Parts of Eastern Minnesota are within the transition zone, and most of the state is still listed as an uninfested zone. Currently, Anoka County is still within the uninfested zone, but the spread of the spongy moth is occurring at a rate of 3 miles per year.

Minnesota's Noxious Weed Law is the policy of the legislature that residents of the state be protected from the injurious effects that noxious weeds have on public health, environment, public roads, crops, livestock, and other property. A noxious weed is a regulated plant species that has been designated as one of the four categories; Prohibited Eradicate, Prohibited Control, Restricted, and Specially Regulated.

The Prohibited Eradicate category include species that are highly damaging with limited distribution. These species are listed with the goal of eradication. Some examples found in Minnesota include Black Swallow-wort, Oriental Bittersweet, and the Tree of Heaven.

The Prohibited Control category include species that are highly damaging and widely distributed. The goal for species in this category is to prevent spreading. Examples in Minnesota include Wild Parsnip, Common Tansy, and Japanese Knotweed.

The Restricted Category include species that are highly damaging with an extensive distribution that limits the ability to control populations. The goal for these species is to prevent new plantings. Examples in Minnesota include Common Buckthorn, Non-Native Honeysuckle, and Garlic Mustard.

Specially Regulated plants may be native, non-native, or demonstrated value. The goal for this category of plants is to craft regulations that prevent issues. Examples in Minnesota include Poison Ivy, Amur Maple, and Winged Burning Bush.

Species on this list and new potential treats are reviewed by the Noxious Weed Advisory Committee. This committee is comprised of members that represent conservation, business, tribes, and government interests. A thorough risk assessment is completed for a species before a listing recommendation is made by the committee. You can report a potential population of a species on the Minnesota Noxious Weed List by taking a picture of both the leaves and flowers, taking note of the location, and sending it to the Arrest the Pest email This email address is being protected from spambots. You need JavaScript enabled to view it. or by filing out the online reporting form on the website https://mdaonbase.mda.state.mn.us/AppNetUF/UnityForm.aspx?key=UFKey.

Below is a list of species to keep a look out for. Some of these species are already listed as Prohibited Eradicate in Minnesota and have very limited distribution. Looking for these species can prevent new populations from invading the state. Other species on the list have not yet been found in Minnesota, but have caused substantial damage in other parts of the country. Early detection and eradication is crucial in protecting Minnesota against invasive species.
