Ruben Nazario

Restoration Specialist

Ruben Nazario has lived in McHenry County, Illinois, for 14 years. He recently enrolled his own property into the Conservation Stewardship Program (CSP) of the Illinois Department of Natural Resources. The CSP has given Ruben the opportunity to apply to his own land what he has learned about restoration and management while reducing his tax burden. He is delighted to share his insights and experience with other similarly situated landowners.

Ruben developed a love of gardening and of the outdoors as a child and a love of the woods and natural areas while vacationing often with his young family in the Nicolet National Forest in Wisconsin. In recent years, Ruben has been volunteering frequently with the McHenry County Conservation District in support of natural resource management, primarily focused in the restoration of oak and hickory woodlands. 

After a successful career in software development for AT&T, Ruben's goal and passion is to now spend as much time as possible outdoors battling the invasive plants that are threatening our Midwestern native plant species and ecosystems or, has Ruben has called it, "Extreme Weeding."

Ruben tells his friends and family "I'd rather be pulling buckthorn than fishing. Guaranteed piles of catches, more purposeful than working out at a gym, and we're doing a service to nature and mankind." 

His favorite saying while working is, "Look, there's another one!"
