During the course of the year, we will have the pleasure of bringing you news about amphibian conservation efforts directly from the field. In some cases these will be reports filed by Houston Zoo staff who are working with native or exotic species, but we also expect to receive regular updates from our colleagues working in other states and countries – all of which we are happy to share with visitors to this website.
Peter Riger, the Houston Zoo's Assistant Director of Conservation, traveled to Sabah Borneo in March 2008 and accompanied Malaysian amphibian biologists in an area amphibian field survey. Monitoring methods utilized for amphibians included surveys, data collection, morphological data and records. On each of three nights, the team went out for 2 hours to three different sites: a small oil palm plantation, forest edge behind the B&B where they were lodging. Over these 6 hours they located 51 individuals from 18 species in 9 genera. Each individual was bagged and brought back to the research station and then weighed, measured and photographed before being released back to the original site.

Edgardo Griffith, Director of EVACC, and Paul Crump, Reptile and Amphibian Keeper at the Houston, were joined by Eric Baitchman, from Zoo New England, Dustin Smith, from Busch Gardens, and Tim Herman and Maria Tumeo from Toledo Zoological Society, for a six day field excursion to the Cerro Brewster region of central-eastern Panama. The trip yielded a diverse quantity of reptiles and amphibians, a total of about 60 species were found. Priority taxa collected for ex situ conservation tactics included the Horned Marsupial Frog (Gastrotheca marsupiata), the Casque-headed
Treefrog (Hemiphractus fasciatus), the Panama Robber Frog (Eleutherodactylus museosus), the Tabasara Robber Frog (Craugastor tabasarae), and the Sapo Limosa (Atelopus limosus). The sad reality is that although healthy populations of amphibians now thrive in this untouched pristine area in roughly 2 to 4 years the deadly chytrid fungus will most likey sweep through Cerro Brewster wiping out every amphibian in its path. ~Photos courtesy of Paul Crump
Sirens (Siren intermedia texana) were the most abundant amphibian detected, about half were caught in the minnow traps and half were caught with the seine. A Rio Grande Leopard frog (Rana berlandieri) was caught in a minnow trap. Newts were found, all with the seine.
The team also collected environmental data with the goal of establishing a model with which to determine of newts might be present at a new site. Driving from the refuge at the end of the day, a Western Diamondback Rattlesnake (Crotalus atrox) was seen crossing the road.
