Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Artificially mist habitat to keep it damp One before-and-after study in Tanzania found that installing a sprinkler system to mitigate against a 90% reduction of river flow did not maintain a population of Kihansi spray toads.
