Buffalo Bayou Invasive Plant Eradication Unit (2011) is an artwork by Mark Dion. Currently, in BBP’s collection, the work was commissioned with the Houston Arts Alliance. The artwork responds to Houston’s wetlands’ key challenge: the proliferation of non-native species. Dion’s mobile unit is not only a work of art but also a working outpost that supports volunteers as they remove invasive plants that negatively impact biodiversity. Blurring the distinction between the truck’s status as artwork and a functional tool is, as Dion has stated, “how an artist today makes a consideration of the landscape.”

During BBP’s 2025 Summer Species series, the Invasive Plant Eradication Unit will be on view at The Water Works Visitor Center in Buffalo Bayou Park May through August on the second Saturday of the month from 9 – 11am. Learn more about the Summer Species series and how to participate here.
