Why goats?

Goats aren’t picky eaters. They eat the woody, shrub-like invasive plants (and everything else), as well as pesky poison ivy, without any negative affect. Utilizing this innovative yet simple method reduces the need for heavy herbicide application, which is cost-effective for the department. It also allows access to locations where mowers or machinery could otherwise not reach. Goats grazing simulate mowing, which can initially stimulate growth. However, repeat “applications” of grazing goats has shown to eliminate 90% of invasive, woody plants over three years.  The goats aren’t able to eradicate unwanted plants, but they push them back enough that an herbicide follow-up treatment is possible and effective.

This is a video City Of Holland, Michigan – City Hall put together about the Prescribed Browsing Project. Check it out to learn what our Eco Goats are all about.


Eastmanville Bayou before goat treatment (2011) – completely overrun with oriental bittersweet. It was quickly becoming a mono-culture of bittersweet. You can’t tell, but this photo was taken along the Grand River.

Oriental bittersweet can “girdle” and eventually pull down fully grown trees.
