Researchers at the University of Massachusetts Amherst recently published a pair of papers that, together, provide the most detailed maps to date of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.
Together, the papers, published in Diversity and Distributions and BioScience, and the publicly available maps, which track species at the county level, promise to give invasive species managers in the U.S. the tools they need to proactively coordinate their management efforts and adapt now for tomorrow's warmer climate.
Mapping future abundance
One of the major hurdles in addressing the threat of invasive species is in determining when and where a species crosses the line from being non-native to invasive. A single occurrence of, say, purple loosestrife does not make an invasion. Invasive plant managers need to know where a species is likely to take over, outcompeting native plants and altering the ecosystem.

Florida is overrun with kudzu.
Invasive plants....My goodness...we brought millions of different plants into our country. Now they’re saying they’re invasive.
Initially, nurseries are the problem in some cases. The flowering white pear will take over North America, one subdivision at a time. Don’t even get me started on that damnable pestilence Bush Honeysuckle (originally sold by nurseries back in the 60s as privacy screens).
Unfortunately, Florida ranked worst for invasive species; warm temperatures, plenty of rainfall, and plenty of birds.
Siberian Elm is another I had here in my backyard. Killex worked on it, though! I cut it to the stump, and every time it sent out shoots I hit them with the sprayer. 5 months in it was dead. I pulled the stump in September, and the roots were already starting to weaken.
Or stupid people planting bamboo because “It’s pretty!”
“It’s Pretty”?
Pretty Invasive.
I have honeysuckle close to my house at the farm, that was from cutting at my grandmother’s mother’s house.
I have a Lilac bush that is from cuttings from a Lilac bush brought from Virginia to Texas by my Grandmother’s family. We planted it in my daughter’s yard in N. Virginia.
They have labeled as invasive what my grandmother had in her flower bed by her front door, perrywinkle (Vinca). They never were invasive in this part of Texas.
I can think of a lot of plants that are invasive, my family has owned and operated farms in this county since 1889.
I know about invasive weeds.
Bump
And it IS NOT by Climate Change.
Climate is not changed by man, but it has changed throughout time.
We have total inundation of Bush Honeysuckle around here. Nothing grows under a mature stand of this. No new growth tree, weeds, grass nothing. If it’s not mowed or tilled around here you’ll find a thick, 15 foot high canopy with a barren dirt desert beneath.
Shut down all of the marijuana grows!
So how many of those ‘Latin’ names were based on White Men?
Precisely my point. Been trying to get rid of some for a while.
It is always a local issue, custom harvesters of grains are big spreaders. too.
Our honeysuckle is climbing variety. It is hardy, but not invasive. We are periodically drought prone.
Thanks for the ping; I’ll alert the Troops!
When I managed a Garden Center, we were very aware of this - and stopped selling certain things; Barberry and Honeysuckle immediately come to mind.
It was a constant ‘education process’ to explain to customers why we weren’t selling some items, anymore.
Every year we’d get a current list from our local DNR as to what was going on. It wasn’t a LOT of plants; not as extensive as the list you posted, but Wisconsin is mainly Zone 4 & 3, with a smattering of Zone 5 - and a lot of ‘invasives’ can’t make it through a Wisconsin Winter, anyhow.
I agree that some of the invasive/imported BIRDS are a bigger problem than plant material. But, what do I know? I’m just your average uneducated RUBE in the eyes of Mother Government, who always knows best. *Rolleyes* ;)

Nice list!
