Trevor Pellerite
Founder | President
Trevor is the founder and President of Grasslands Unlimited. After earning a writing degree at Northern Michigan University, he moved to Montana where he worked as a hunting guide in the plains of northeastern Montana. While chasing mule deer and antelope through the sage, Trevor fell in love with the expansive grasslands of the American heartland, and eventually decided to pursue a career in wildlife and public land advocacy.
Trevor attended law school at the University of Colorado, where he won the Getches-Wilkinson Center for Natural Resources, Energy and the Environment Outstanding Student Award. After practicing law for several years, Trevor returned to school at the University of Nebraska at Omaha to earn a master’s degree in biology, where his research focuses on comparing small mammal communities in restored and unrestored roadsides.
Harmon Zuckerman
Board Member
Harmon is an attorney focused on land use law and who also counsels clients in water law, real estate, and civil litigation matters. Before becoming a lawyer, he had two careers: one as a land use, environmental, and community planner in the public and non-profit sectors and another in building and design. As a planner, he directed the update of the Tahoe Regional Planning Agency’s regional plan and served as the head planner for Douglas County, Nevada, updating the county’s master and open space plan documents and drafting numerous ordinances that preserve ranchland while increasing the economic vitality and enhancing the built environment of the Carson Valley’s small towns.
In the construction field, he was both the owner of a design/build firm and a construction manager, in both cases focusing on adaptive reuse and historic preservation projects. Harmon attended law school at the University of Colorado, and while there he interned for a Federal judge, performed pro bono work to protect and preserve the acequia community irrigation systems in southern Colorado, and became a founding CPI Board Member. Harmon serves on the Planning Board for the City of Boulder and, in his spare time, enjoys family life and a seemingly ever-expanding range of outdoor activities.

Samuel Kanne
Treasurer & Board Member
Growing up a few miles outside of small town Iowa, Sam spent much of his childhood exploring the woods along the Boyer River, as well as an old settler cemetery that held some of the only virgin prairie in his county. It was during this time that he came to love the great plains and all of the nature it holds. He didn’t know it at the time, but his former stomping grounds held one of the largest populations of white trillium in Iowa.
Sam went on to serve as a camp counselor at a summer camp for 7 years. 7 summers spent living in the woods cemented his love nature and introduced him to the importance of connecting kids with nature through volunteerism. This experience led him to pursue a degree in Sustainability Studies at UNO.
Today, Sam works full time for Scouting America, where he helps volunteer leaders organize activities all across Nebraska and Western Iowa, ensuring financial responsibility along the way.
