Ticks and bush honeysuckle

Editor’s note:  Looking for more motivation to get rid of bush honeysuckle?  Or perhaps you’d like to tell your neighbors about the importance of removing invasive species?  Judy Ward shared this article about a study done at Washington University.

WUSTL scientists says suburban influx of deer, invasive plants are affecting human health — from an article by Diana Lutz —

 

“You don’t have to go out into the woods anymore,” says tick expert Brian F. Allan, PhD, who just completed a postdoctoral appointment at Washington University in St. Louis. “The deer are bringing tick-borne disease to us.”

So, it stands to reason that anything deer like might increase the risk of tick-borne disease for people. The invasive plant bush honeysuckle, for example.

In places it was distinctly bushy or brushy and in others there were scattered trees. In still others, grassy parks and groves of trees intermixed.

Some of Soulard’s plats clearly show that groves of trees (arboleda, in Spanish) occupied sinkhole depressions in an otherwise grassy karst plain. One French habitant testified that “the spot immediately where the town now stands was very heavily timbered, but back of the town it was generally prairie, with some timber growing, but where the timber did not grow it was entirely free from undergrowth, and the grass grew in great abundance everywhere, and of the best quality; but where the inhabitants used to cut their hay was where Judge Lucas now lives (Locust and 13th), and between his house and the cottonwood trees, it being all prairie” (Hunt’s Minutes 1825).

A grandpa’s sage advice may be the biggest breakthrough in bug repellent since DEET. Scientists with the USDA’s Agricultural Research Service (ARS) have isolated two insect‑repelling compounds from leaves of the American beautyberry plant (Callicarpa americana), a shrub native to much of the southeastern United States.
