Chris Taylor, a Geo-Marine, Inc. (GMI) wildlife biologist, in conjunction with United States Army Corp of Engineers (USACE) CERL-22 research, provided support of a Herpetofauna Inventory Study on Fairchild Air Force Base (FAFB), Washington.

The goal of the study was to determine the reptile and amphibian populations using FAFB lands. GMI used a variety of survey techniques to help the engineers’ CERL-22 Research Team, including road-cruising, cover boards, time-constrained visual encounter surveys, amphibian call surveys and anuran acoustics monitoring via Wildlife Acoustics’ Song Meter SM2+ (aka Frog Logger). 

Ample data were collected to characterize the reptile and amphibian populations on the base, including the discovery of multiple populations of the Columbia Spotted Frog (Rana luteiventris), a state Candidate species. 

In addition to providing support for the Herpetofauna Inventory Study, GMI also helped to swab frogs to provide samples to test for the presence/absence of the Chytrid Fungus (Batrachochytrium dendrobatidis). This fungus infects almost 450 amphibian species globally, resulting in 100 percent mortality in some of the infected species.
