Best Native Trees for our Changing Climate

Climate change has many impacts on the natural environment and there are many ways we can help reduce climate change. There is yet another way to help with the impacts of climate change. Planting a diversity of trees that are predicted to thrive in a changing climate will help the landscape adapt and become more resilient.

Minnesota's climate is changing. Average temperatures have increased 1 - 3 ◦F statewide with the greatest temperature increases in the winter. Total precipitation has increased with more intense rainfalls. Despite the increase in total precipitation, there have been more days between precipitation events, which increases the potential for drought. The US National Climate Assessment predicts that these trends will continue in Minnesota. By the end of the century, Minnesota will likely have the summer climate of Nebraska and Kansas (Figure 1). Plant communities and habitat types will change along with the changing climate. Most tree species northward range are predicted to shift about 300 miles by the end of the century (McKenney et al. 2007). The change in tree cover alters the understory and the habitat for wildlife. One way to help the landscape adapt and become more resilient is to plant a diversity of trees and include species from more southern areas.

US Forest Service climate change models predict these trees are likely to thrive in a changing climate in the Metro region:

Tree Species

Habitat

American elm *

Average – Moist soil, floodplains, deciduous forest, swamps

Basswood

Deciduous forests, woodland edges

Black Oak

Savanna

Black Walnut

Mixed forest, Savannas, banks

Bur Oak

Forest to open prairie

Cottonwood

Lowland forests along along lakes and streams, floodplains

Hackberry

Average – Moist soil, Hardwood forest, floodplains, river bank

Shagbark hickory

Upland dry forest

Silver maple

Floodplain forest, riverbanks

White Oak

Upland dry forest

* disease resistant needed


Consider the habitat, moisture, soil, and sun conditions when selecting trees for your property.

Winter Buckthorn Treatment is Underway

Common and glossy buckthorn are common invaders in native landscapes; common buckthorn grows mostly in upland environments while glossy buckthorn grows in wetland environments. ACD is working to control buckthorn at sites that still have intact native plant communities and rare plants to ensure those quality sites do not become further degraded. Work this winter is taking place at Robert and Marilyn Burman WMA, Cedar Creek Ecosystem Science Reserve, and Blaine Preserve SNA with funds from the Clean Water, Land and Legacy Amendment.

Look Out for Oriental Bittersweet

Now that there are no leaves on the trees, it is a good time to look for Oriental Bittersweet (Celastrus orbiculatus). This invasive species is on the ERADICATE list. It is a vine that girdles and smothers trees and shrubs. Look for the bright red fruit with yellow capsules.

Be sure to check your ID with the native American bittersweet, which has orange fruit capsules instead of yellow. American bittersweet fruits are found only at the end of the vine while Oriental bittersweet has fruit at the leaf axils.

The Recovery of the Wild Turkey Population in Minnesota

Wild Turkey - MN DNR

Did you know that wild turkey had gone from a native population of millions of birds to being almost extirpated by 1900 in the United States?

The restoration of the American wild turkey is one of the greatest wildlife conservation success stories.

That success story began in 1973 in Minnesota. The MN DNR traded a flock of its homegrown ruffed grouse for 29 turkeys from Missouri. The Missouri-born birds were released in Houston County in southeastern Minnesota and the population grew rapidly. Many partnering turkey advocates aided in their return, including members of the National Wild Turkey Federation who helped transport the flocks to new habitats. The restoration of the wild turkey over the past 25 years is one of Minnesota's greatest conservation success stories. Once rare, today wild turkeys are becoming a common sight throughout southern and western and even central Minnesota.

Wild Turkeys live year-round in open forests with interspersed clearings. They nest on the ground in dead leaves at the bases of trees, under brush piles or thick shrubbery, or occasionally in open fields. Wild turkeys are omnivorous, and their diet changes by the season: in spring and summer, they eat insects, seeds, and leafy vegetation; in fall and winter, they eat tree nuts, seeds, and berries. They will also eat small amphibians and reptiles. Poults, young turkeys, feed heavily on insects.

The Anoka Conservation District with funds from the Outdoor Heritage Foundation and National Wild Turkey Foundation is enhancing turkey habitat at the Robert and Marilyn Burman WMA and Gordie Mikkelson WMA. Tree thinning and buckthorn removal will open the forest and promote oak regeneration. Acorns are a favorite fall food. Increased native plant diversity in the woodlands, savanna, and prairies will attract a diversity of insects, providing a high protein food source.

Give thanks to the many conservationists who worked to restore wild turkey populations and their habitat.

Buckthorn ID and Control

Late September through the end of October is a good time to inventory common buckthorn on your property. Common buckthorn leaves remain green longer than most Minnesota native trees and shrubs so they will stand out when other trees and shrubs are changing color and dropping leaves.

Common buckthorn (Rhamnus cathartica) can be found in upland forests. Look for the thorn, which can be found at the end of some branches.

Glossy buckthorn (Frangula alnus) can invade wetlands. There are no thorns. Look for the rust colored terminal bud.

See the buckthorn fact sheet for tips to identify buckthorn, learn about native look-alikes, and find methods for controlling buckthorn.

For a safe way to treat buckthorn stumps, you can apply herbicide with buckthorn blasters/dobbers: https://landscape-restoration.com/

See the DNR's buckthorn management page for more information.
