"Students and faculty managing the Ithaca College Natural Lands are in the process of removing what they hope is the last of an invasive species of plant known as Japanese stiltgrass after six years of sustained eradication efforts. On Sept. 26, the group cleared out a majority of the remaining stiltgrass.
"Bittersweet — it's the perfect name for a plant that has some lovely qualities but is also a terrible menace. Many people are familiar with this plant because it has been used for autumn decorations. It grows as a vine with an orange-red berry enclosed in a bright yellow casing.
The supple twisting stem and colorful berries make the bittersweet ideal for creating a fall wreath to hang...
"STERLING - There is a swath of grass cut on the edge of a field at Michael Pineo's farm about one-and-a-half highway lanes wide, but even that does not protect the field from one of Central Massachusetts' most challenging invaders.
"It still spreads everywhere," he said, pointing to tree-sized bushes of autumn olive - plants once used for roadside stabilization but now are an invasive...
"Most readers are familiar with monarch butterflies (Danaus plexippus). The striking orange and black species has historically been widespread throughout North America.
Its life history makes it an attractive tool for lessons about insect ecology. Monarch caterpillars forage exclusively on milkweed (Asclepias). Foul-tasting chemicals they acquire from the plants render monarch...

"ESSEX, Vt. -
As a landscaper, Judson Kimble is used to pulling out tough weeds. But this plant fought back.
"The foliage, the stems, the flowers. Any of it. If you break it, it all has juice inside of it," Kimble said.
