Betsy Butler (Pittsburgh, Pennsylvania, USA) and Susan Parrish (Wheaton, Illinois, USA) will become part of an interdisciplinary initiative to assist local communities in mangrove conservation by sampling tree and shrub density, identifying species composition, collecting plants for further research, running transects for a diversity of birds, and capturing and marking crocodiles to assess their population status and vulnerability. Coastal mangrove forests play a pivotal role in Mexico, preventing erosion and sedimentation of coral reefs, providing key nursery areas for fishes, and offering crucial habitat for American crocodiles, boat-billed herons, and other wildlife. July 31-August 11
