Environmentalists in Taiwan have been helping frogs to cross a road and get to a creek safely for the last three years.
During the month of October, the Society of Wilderness in Hsinchu county monitors the road alongside local students to avoid deaths.
Campaigners say the Sauteris frog is increasingly under threat as humans encroach on their habitat.
