Join a volunteer ranger at the Neal Smith National Wildlife Refuge on Saturday, May 25, at 1:30 pm for a short presentation on the history and management of the American bison. Take a guided walk along the half mile Overlook Trail to have an opportunity to observe the refuge’s herd of 65 bison including the ten calves born this spring. We recommend that you wear sturdy, closed-toe shoes, wear long pants and bring insect repellent, sunscreen and drinking water. To pre-register, call 515-994-3400 or email Doreen_vanryswyk@fws.gov.
