'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.    Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F807https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F807Thu, 22 Aug 2013 15:03:13 +0100Collected Evidence: Collected Evidence: Artificially shade ponds to prevent desiccation We found no evidence for the effects of artificially shading ponds to prevent desiccation on amphibian populations.
