Collected Evidence: Collected Evidence: Engage landowners and other volunteers to manage land for amphibians Two before-and-after studies (including one replicated study) in Estonia and Taiwan found that habitat management with participation of volunteers increased natterjack toad and Taipei frog populations. One controlled study in Mexico found that engaging landowners in aquatic habitat management increased axolotl weight. Six studies in Estonia, the USA and UK found that between eight and 41,000 volunteers were engaged in aquatic and terrestrial habitat restoration programmes for amphibians. Individual programmes restored up to 1,023 ponds or over 11,500 km2 of habitat.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F777https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F777Wed, 21 Aug 2013 14:39:26 +0100Collected Evidence: Collected Evidence: Pay farmers to cover the costs of conservation measures Three studies (including one replicated study) in Denmark, Sweden and Taiwan found that payments to farmers created amphibian breeding habitat or increased frog or toad populations. However, a second study in Taiwan found that payments did not maintain green tree frog habitat. One replicated, site comparison study in the Netherlands found that ditches managed under agri-environment schemes had higher numbers of amphibian species and higher abundance than those managed conventionally.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F818https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F818Fri, 23 Aug 2013 09:47:58 +0100
