A semi-regular description of what’s going on at the drift fences on the Savannah River Site. Most will refer to Rainbow Bay--an isolated wetland completely encircled by a drift fence with pitfall traps. The Rainbow Bay fence has been “run” every day since September of 1978! We'll also talk about all types of fieldwork occurring at the Carolina Bays and other wetlands on site.

Snazzy opacum photos
About thirty more desperate male marbled salamanders came into Rainbow Bay today. Our brief chance of rain came and went without a drop. Only warning on the weather channel now is for high risk of fire! In other words, it’s going to stay dry for a while. Thought I’d show you what these guys look like when they get their photos taken. All of them are put on the same background (some red felt), illuminated from above, and a counter is kept in the field of view. All marlbeds coming into the bay that have a cohort mark (meaning they were born in the bay and have been marked in a way that we know what year they were born). The critter on the left is a one-year old and on the left is a three-year old. These two have fairly similar patterns but still you can tell them apart by the patterns of the white “bars” across their backs and the amount of white on the head. Since the “cohort” mark doesn’t provide an individual mark the photos can serve that purpose. Also just shows how incredibly beautiful they are! Ok, time to do a rain dance.
