Barb Beasley has been an (almost) one-woman amphibian ambassador on the west coast for the last decade or so. The SPLAT project (not it's actually name, but as we affectionately call it: Society for the Protection of Little Amphibian Tragedies [or Little Animals Trampled]) began years ago when Barb was trying to get a sense of where amphibian corridors meet the highway. She enlisted the help of volunteers who would go out early in the morning after a rainfall to count the "splats" on the highway. From there she determined the main amphibian freeway, which is near the junction. Then Barb erected the little fences you have probably seen. These coralled the amphibians and she then carried them across the highway. (Yes, you read that correctly. I told you she was dedicated.) Now those fences funnel the amphibians toward their own tunnel.
Thanks for all of your hard work and dedication, Barb!
