Weed Out Invasive Missouri Trees

The state of Missouri may have one of the best conservation departments in the country, but not even these professionals can completely eradicate the threat of invasive trees by themselves. Preserving the thousands of spectacular Midwest conservation areas requires the utmost cooperation between wildlife officials and Missouri citizens, starting with the most important piece of the puzzle: homeowners.

As buds begin to break open this spring, be on the lookout for one of many detrimental invasive species that could pop up in your yard. Undesirable seeds can be carried from miles around, and could eventually end up in one of Missouri’s prized conservation areas where the MDC is involved with an expensive and never-ending battle against invasives that threaten the biodiversity of our state.

Callery Pear

The callery pear remains one of the most popular ornamental trees in Missouri despite the fact that they spread like wildfire. These highly tolerant plants take over and replace native varieties because they have no natural checks and balances within the ecosystem. Once thought to be sterile, callery pears actually crossbreed with similar varieties to create thorny, unattractive nuisances that require heavy tree maintenance.

Amur Maple and Norway Maple

The Amur and Norway maple is another set of invasive species that can thank unknowing homeowners for their devastating spread. Both are loved for their hardy nature and ornamental properties, but these trees are known as invasive in much of the Midwest. The Norway maple is especially malicious: these trees actually secrete a chemical that kills undergrowth, resulting in barren and muddy forest floors. Homeowners who plant these trees run the risk of pulling up new sprouts for years to come – the same can unfortunately be said for the entire neighborhood.

Missouri is truly blessed with a spectacular variety of native specie that should not be taken for granted. Most invasive species have not even documented yet: the public rarely recognizes them until a major outbreak has occurred, when it is already too late. Certified arborists and local service professionals should be able to identify and remove any “pest trees” on your property – a priceless step toward conserving Missouri wildlife.

Flowering Spring Trees for Saint Louis

Besides the chirping of birds and joyous shouts of children, how do we know it is spring in Missouri? The beautiful flowering trees, of course! The “show-me” state has an abundance of gorgeous and aromatic flowers in the springtime, but the blooming native trees put on the most spectacular show of them all. If you’re putting together your spring planting list, consider the following three native tree varieties to add a bit of floral elegance to your property!

Flowering Dogwood

Cornus florida is a simple species of Dogwood with a surprising twist. This tree generally grows up to 33 feet tall, providing ample shade and windblock for residential areas. The flowers are what gives this species it’s name and popularity: groups of inconspicuous yellow-green buds will grace the branches each spring, only to be replaced by stunningly vibrant red fruits in the fall. The flowering dogwood is a classic Missouri native that will put on a show all year round.

Pawpaw

Hailing from the same family as the custard-apple, sweetsop, and ylang-ylang, the Pawpaw (Asimina) provides the largest edible fruit indigenous to the continent. The name is often considered to be a derivative of “papaya”, because of the visual similarity of the fruits. The leaves begin to come around in April, bringing with them large, beautiful red-purple flowers. Although this variety isn’t very pleasant smelling, planting this native tree will add a touch of the tropics to your Missouri home.

Hawthorn

Hawthorns have a natural presence in almost every county of Missouri, making this tree the perfect hardy candidate for homeowners who want to avoid the bulk of routine tree maintenance. The Hawthorn’s flowers are so beautiful that they have been adopted as the Missouri state flower. The fruits are certain to attract a variety of cheerful birds.
