University of Arkansas Ph.D. Biology Candidate Casey Brewster spends his summers on remnant Ozark glades monitoring the elusive and rare Eastern Collared Lizard. Brewster will lead a Collared Lizard expedition at 9 a.m. Saturday, May 5 during a public hike at Lake Leatherwood Park, where several isolated colonies are documented. The free event is part of a month-long Arkansas Department of Heritage grant program in Eureka Springs, called "Off the Beaten Path" coordinated by the Native Plant Garden Project and Community Development Partnership.
