Celebrating OAKtober

October 8, 2021 By MIPN Coordinator

Did you know that the U.S. has a national tree? I actually didn’t before I started researching for this post, and unlike Canada, we don’t make it super-obvious by putting it on our national flag! Back in 2004, following a public poll by The Arbor Day Foundation, Congress passed legislation establishing “the mighty oak” (all […]

A Forest Without Invasive Creepers: Doesn’t that Sound De-vine?

September 11, 2020 By MIPN Coordinator

twining vine

You’re walking through your woods or perhaps a nearby nature preserve and then you see it: a vine as thick as your forearm making its way up a tree. Being smothered by large vines is not good for trees. The extra surface area and weight from vines make trees more vulnerable to storm damage. If […]

Examining the Relationship between Spotted Lanternfly and Tree-of-Heaven

July 1, 2020 By WIGL

Tree-of-heaven suckers grow in a riparian area in Northeast Illinois.

The invasive pest spotted lanternfly (Lycorma delicatula) likely arrived in the United States as an egg mass hitchhiking on building stone imported from Asia to Southeastern Pennsylvania. The pest was discovered in 2014 when a forester observed adult lanternflies massing on the trunks of tree-of-heaven close to building stone company’s lot. Tree-of-heaven is itself an invasive import […]

Invasive Plant Cultivars: Guilty Until Proven Innocent?

June 1, 2020 By WIGL

Invasive Plant Cultivars: Guilty Until Proven Innocent?

Understanding Invasive Plant Cultivars When a plant species is found to be invasive, it is not always clear if the risk extends to all cultivars, particularly those promoted as low-fruiting or sterile. Unfortunately, some such cultivars have appeared to be sterile in their early years, but eventually started producing viable seed. To guard against such situations, New […]
