Invasive Alert: Chinese Tallow Tree


The state of Alabama doesn’t worry too much about invasive plants like privet or kudzu, which have seemed to take over much of the south. No, the one botanists fear is the Chinese tallow tree.

Also known as the popcorn tree for the white, waxy tallow substance on its fruit that kind of looks like popcorn, this tree is so invasive in Alabama that they have taken to fighting it from the air.

So why should Michigan be concerned?

The U.S. Forest Service has data that shows the tree’s population has grown 500% between 1991 and 2005.

The tree thrives in wetland environments, but is not limited to them. The tree can grow in suburban areas, forest edges, and even sand dunes. It is still a popular ornamental tree in residential neighborhoods for its bright red fall color.

Yet once established this tree spreads quick. One mature Chinese tallow can produce 100,000 seeds every year. Those seeds are spread by birds and other animals, as well as flood waters. And the seeds can stay dormant for years before sprouting.

In addition to seeds, Chinese tallow has an extensive root system, with new shoots sprouting along it. These two things combined mean tallow can grow in clusters so thick that it drowns out all other native plants.

And it’s not that far away. According to a map from the University of Georgia’s Center for Invasive Species and Ecosystem Health, the plant was found in a county in southern Wisconsin as of July 2017.

The moral of this story?

Keep an eye out for plants that look unusual to you. It may be something that doesn’t belong. Learn from Alabama’s experience. If you find something you’re not sure of, check out the Midwest Invasive Species Information Network and report it if it’s invasive.

Be wary of what you purchase at a nursery or your local home supply store garden center. Make sure that it’s native to Michigan and you aren’t becoming the source of a new infestation of an invasive plant.

Alabama fears this invasive plant so much we attacked it from the air

When talking about invasive plants in Alabama, kudzu and privet tend to be the ones people are most familiar with, but they’re not the ones Alabama botanists and wildlife officials are most worried about.

One of those is the Chinese tallow tree, or popcorn tree, one of Alabama’s most invasive species.


The Stink Bugs Are Back

They’re brown, numerous, and annoying. And right now they’re trying to make their way into your homes. Brown marmorated stink bugs.

Every year people are plagued with these pests as they look for warm places to hide for the winter. Unfortunately for us, we’ve made lots of them with our obsession for cozy homes, insulated garages, even storage sheds and barns. All of these provide great protection for these insects during the harsh temperatures of winter.

If you find yourself infested, don’t panic. While irritating, they’re harmless. And there are ways to keep them out of your house.

The article below from Michigan State University Extension gives you a few tips and resources to help.

It’s that time of year again when brown marmorated stink bugs invade structures humans create looking for a place to hunker down for winter. Since last fall when Michigan residents were asked to report brown marmorated stink bugs in their homes, we now know that brown marmorated stink bugs are well-established as a nuisance pest in homes in the southern Lower Peninsula of Michigan.

What are they doing?

Brown marmorated stink bugs are looking for a protected place to hibernate over winter. They will leave your house again in the spring – if they can find their way back out – to look for plants to feed on and lay their eggs outside.

What are they NOT doing?

They are NOT nesting, laying eggs or feeding on anything or anyone in your house. These are plant-feeding insects with straw-like mouthparts for drinking plant juices – they are harmless to humans and pets.

What do you need to do?

  1. Don’t panic.
  2. Look for gaps around window air conditioners or holes in window screens and block them off – these are easy access points for brown marmorated stink bugs to enter houses.
  3. The easiest, non-toxic way to dispose of them is with a couple inches of soapy water in a bucket – the soap prevents them from escaping the water. Sweep them into the bucket and they will drown in the soapy water, which you can then dump outside. Or you can do the same with a Shop-Vac – add the soapy water to the canister before vacuuming them up with the Shop-Vac.
  4. Report how many you’ve seen at a given location using the Midwest Invasive Species Information Network. If you have trouble entering the information on the Midwest Invasive Species Information Network website, leave a message for Julianna Wilson via email at or by phone at 517-432-4766 with your name, address (or nearest crossroads), the date you saw them, and how many you have seen.

The map below shows where we have received reports to the Midwest Invasive Species Information Network of brown marmorated stink bugs in the Lower Peninsula since Sept. 25, 2015.
