Dallas Zoo’s Giants of the Savanna is the first exhibit in the United States to allow elephants, giraffes, zebras, impala and ostrich to mix in habitats at the same time, while Fort Worth Zoo’s Museum of Living Art (MOLA, schematic design by CLR) sets new standards for herpetariums. The updated edition of Wild Mammals in Captivity: Principles and Techniques for Zoo Management, the definitive scholarly text on the subject, contains Greg Dykstra and Jon Coe’s contribution “New and Sustainable Directions in Zoo Exhibit Design.”
