Aripo Savanna & its Herpetofauna

Trinidad’s Aripo Savanna complex of tropical grasslands, palm islands, marsh forest and moriche palms with numerous slow moving streams, ponds, and puddles. On June 18-19 the Herp Group from the Trinidad and Tobago field Naturalists Club surveyed the herpetofauna. The weather cooperated to a degree with occasional showers and thunderstorms and blistering heat, which creates a very nice sauna-like effect. The TTFNC-HC will summarize the results elsewhere, but here are a few of the highlights.
Rare creatures are sometimes sited on the savanna. Here is Graham White looking 
for them while well camoflaged.
