Collected Evidence: Collected Evidence: Legal protection of species Three reviews (including one systematic review) in the Netherlands and UK (Bosman et al. 2011, Spitzen-van der Sluijs et al. 2011, Lewis 2012) found that legal protection of amphibian species was not effective at protecting populations during development. Two reviews in the UK (Edgar et al. 2005, Lewis 2012) found that the number of great crested newt mitigation licences issued over 10 years increased to over 600 in England and Wales.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F779https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F779Thu, 22 Aug 2013 11:46:02 +0100Collected Evidence: Collected Evidence: Protect brownfield or ex-industrial sites We found no evidence for the effects of protecting brownfield sites on amphibian populations. '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%2F786https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F786Thu, 22 Aug 2013 14:26:33 +0100Collected Evidence: Collected Evidence: Restrict herbicide, fungicide and pesticide use on and around ponds on golf courses We found no evidence for the effects of restricting herbicide, fungicide or pesticide use on or around ponds on golf courses on amphibian populations.
