Is an Invasive Plant Species in Your Backyard?
LREC has produced a new brochure detailing identification information and removal recommendations for ten of the most threatening invasive species of the River des Peres watershed. Native alternatives are also listed. You can download the brochure or request a copy from a member of the staff.

More Bush Honeysuckle Demolition!!
Intern John Lee and I removed this large pile of bush honeysuckle from the edge of the woods in one single afternoon! The area was much sunnier once we were done.

Giant Garlic Mustard Tap Roots
Check out these monster tap roots on this garlic mustard that I pulled from the creek bank! Garlic mustard (Alliaria petiolata) is an invasive weed that invades forested communities and edge habitats. It was first thought to have been introduced to North America as a cooking herb. As a biennial, it produces basal rosette leaves during its first growing season and then bolts during its second growing season to produce copious amounts of seeds. In fact, garlic mustard spreads exclusively by its seeds, mostly via floodwaters and also on humans, animals, and vehicles. The seeds can remain viable in the soil for at least seven years, but if control measures are taken to prevent the plants from setting seeds its spread can be prevented. We have quite a few infestations of this invasive species at LREC. Staff, volunteers, and even students will continue to pull garlic mustard during the months of October through March before it starts setting seed in April. Staff is also exploring other ways in which we can actively control this species, one of which is spraying select infestations in the early spring. Ultimately, enlisting other watershed neighbors in managing this species and other invasives is the only way to slow the source of seed influxes on our property. A challenge for all of us to work together!
