Natural resources is a division of the operations and recreation department. This division works to protect, restore and enhance the natural areas and resources of St. Louis Park, including a diverse urban tree population, a wide array of wildlife, 28 water bodies and
Westwood Hills Nature Center.
Stewardship of these resources is vital and important to the St. Louis Park community. Responsibilities of the division include:
Urban forestry programs.
Education and outreach.
Landscaping and restoration.
Invasive species management.
Weed ordinance enforcement.
Natural resource development review and guidance.
There are all kinds of ways to get involved and help the city protect its natural resources. Participate in community tree planting or the annual Minnehaha Creek cleanup, attend a workshop or be an adopt-a-park or garden volunteer. Watch St. Louis Park social media sites, view the
calendar and check Park Perspective for more information on these and many other opportunities.
How can I protect my trees from bur oak blight?
A new disease called bur oak blight (BOB) has been identified in the Twin Cities area and is affecting bur oak trees in St. Louis Park. BOB mimics the symptoms of oak wilt disease, with lots of brown leaves appearing in a tree’s crown and falling off during the latter half of the growing season, typically late to mid-July. BOB tends to be most prevalent during growing seasons that start out cool and wet. Successive years of BOB on your tree can kill your tree. The best treatment for BOB is a fungicide treatment administered by a St. Louis Park-licensed tree service in the early spring. Check your bur oak trees now to see if they are displaying and/or losing brown leaves and plan with your licensed tree service for treatment early next spring.
A list of licensed tree service providers in St. Louis Park can be found under the
Tree Care section.
How can I protect my trees from the emerald ash borer?
The emerald ash borer (EAB) is an invasive insect that could potentially kill all ash trees (except mountain ash) in Minnesota. It has not yet been found in St. Louis Park, but it has been found in several areas of the Twin Cities. To help us slow down this insect, DO NOT remove any ash trees or ash wood from your property without first contacting the city’s forestry division at 952.924.2699 or
There’s a lot you can do to protect your trees from EAB, including pruning, chemical injections and having your trees inspected annually. St. Louis Park has teamed up with Rainbow Treecare to offer discounted preventative EAB injections for ash trees on private property. To schedule a visit or to get an estimate, contact Rainbow Treecare at 952.767.6920 or
firstname.lastname@example.org, or visit the Rainbow Treecare website. To schedule an appointment to have your trees inspected by the city, email email@example.com or call 952.924.2562. Tree inspections are provided by the city at no cost to residents.

Minnesota Department of Natural Resources and the Minnesota Department of Agriculture.
How can I protect my trees from Dutch elm disease and oak wilt?
If you have a healthy elm tree or an infected oak tree, you may wish to have your tree injected with a fungicide that prevents Dutch elm disease or halts oak wilt disease. The City of St. Louis Park will reimburse you for 15 percent of the cost of a three-year warranty injection. Download the
request for reimbursement form. For questions or concerns about tree injections, please contact Jim Vaughan at 952.924.2699 or firstname.lastname@example.org.
Dutch elm disease. Symptoms include wilting of one or more of the upper branches (leaves on these branches turn brown, wilt and eventually fall off) and brown staining of the wood immediately under the bark (in healthy trees, the sapwood is milky white).
Oak wilt disease. A tree infected with oak wilt will have leaf discoloration, which begins at the outer edge of the leaf and progresses inward. Leaves turn a dull green, bronze or tan and finally turn brown and shrivel. Oak wilt may be transmitted from tree to tree through root grafts (root transmission), so two or more oaks growing closely together may infect each other.
