Description: Conservation of the planet's biodiversity will depend on international policy intervention, yet evidence-based assessment of the success of such intervention is lacking. Poor understanding of the effectiveness of international policy instruments exposes them to criticism or abandonment and reduces opportunities to improve them. Comparative analyses of population trends provide strong evidence for a positive impact of one such instrument, the European Union's Birds Directive, and we identify positive associations between the rate of provision of certain conservation measures through the directive and the response of bird populations. The results suggest that supranational conservation policy can bring measurable conservation benefits, although future assessments will require the setting of quantitative objectives and an increase in the availability of data from monitoring schemes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Donald, Paul F -- Sanderson, Fiona J -- Burfield, Ian J -- Bierman, Stijn M -- Gregory, Richard D -- Waliczky, Zoltan -- New York, N.Y. -- Science. 2007 Aug 10;317(5839):810-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Royal Society for the Protection of Birds, The Lodge, Sandy, Bedfordshire SG19 2DL, UK. paul.donald@rspb.org.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17690296" target="_blank"〉PubMed〈/a〉

Description: Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffmann, Michael -- Hilton-Taylor, Craig -- Angulo, Ariadne -- Bohm, Monika -- Brooks, Thomas M -- Butchart, Stuart H M -- Carpenter, Kent E -- Chanson, Janice -- Collen, Ben -- Cox, Neil A -- Darwall, William R T -- Dulvy, Nicholas K -- Harrison, Lucy R -- Katariya, Vineet -- Pollock, Caroline M -- Quader, Suhel -- Richman, Nadia I -- Rodrigues, Ana S L -- Tognelli, Marcelo F -- Vie, Jean-Christophe -- Aguiar, John M -- Allen, David J -- Allen, Gerald R -- Amori, Giovanni -- Ananjeva, Natalia B -- Andreone, Franco -- Andrew, Paul -- Aquino Ortiz, Aida Luz -- Baillie, Jonathan E M -- Baldi, Ricardo -- Bell, Ben D -- Biju, S D -- Bird, Jeremy P -- Black-Decima, Patricia -- Blanc, J Julian -- Bolanos, Federico -- Bolivar-G, Wilmar -- Burfield, Ian J -- Burton, James A -- Capper, David R -- Castro, Fernando -- Catullo, Gianluca -- Cavanagh, Rachel D -- Channing, Alan -- Chao, Ning Labbish -- Chenery, Anna M -- Chiozza, Federica -- Clausnitzer, Viola -- Collar, Nigel J -- Collett, Leah C -- Collette, Bruce B -- Cortez Fernandez, Claudia F -- Craig, Matthew T -- Crosby, Michael J -- Cumberlidge, Neil -- Cuttelod, Annabelle -- Derocher, Andrew E -- Diesmos, Arvin C -- Donaldson, John S -- Duckworth, J W -- Dutson, Guy -- Dutta, S K -- Emslie, Richard H -- Farjon, Aljos -- Fowler, Sarah -- Freyhof, Jorg -- Garshelis, David L -- Gerlach, Justin -- Gower, David J -- Grant, Tandora D -- Hammerson, Geoffrey A -- Harris, Richard B -- Heaney, Lawrence R -- Hedges, S Blair -- Hero, Jean-Marc -- Hughes, Baz -- Hussain, Syed Ainul -- Icochea M, Javier -- Inger, Robert F -- Ishii, Nobuo -- Iskandar, Djoko T -- Jenkins, Richard K B -- Kaneko, Yoshio -- Kottelat, Maurice -- Kovacs, Kit M -- Kuzmin, Sergius L -- La Marca, Enrique -- Lamoreux, John F -- Lau, Michael W N -- Lavilla, Esteban O -- Leus, Kristin -- Lewison, Rebecca L -- Lichtenstein, Gabriela -- Livingstone, Suzanne R -- Lukoschek, Vimoksalehi -- Mallon, David P -- McGowan, Philip J K -- McIvor, Anna -- Moehlman, Patricia D -- Molur, Sanjay -- Munoz Alonso, Antonio -- Musick, John A -- Nowell, Kristin -- Nussbaum, Ronald A -- Olech, Wanda -- Orlov, Nikolay L -- Papenfuss, Theodore J -- Parra-Olea, Gabriela -- Perrin, William F -- Polidoro, Beth A -- Pourkazemi, Mohammad -- Racey, Paul A -- Ragle, James S -- Ram, Mala -- Rathbun, Galen -- Reynolds, Robert P -- Rhodin, Anders G J -- Richards, Stephen J -- Rodriguez, Lily O -- Ron, Santiago R -- Rondinini, Carlo -- Rylands, Anthony B -- Sadovy de Mitcheson, Yvonne -- Sanciangco, Jonnell C -- Sanders, Kate L -- Santos-Barrera, Georgina -- Schipper, Jan -- Self-Sullivan, Caryn -- Shi, Yichuan -- Shoemaker, Alan -- Short, Frederick T -- Sillero-Zubiri, Claudio -- Silvano, Debora L -- Smith, Kevin G -- Smith, Andrew T -- Snoeks, Jos -- Stattersfield, Alison J -- Symes, Andrew J -- Taber, Andrew B -- Talukdar, Bibhab K -- Temple, Helen J -- Timmins, Rob -- Tobias, Joseph A -- Tsytsulina, Katerina -- Tweddle, Denis -- Ubeda, Carmen -- Valenti, Sarah V -- van Dijk, Peter Paul -- Veiga, Liza M -- Veloso, Alberto -- Wege, David C -- Wilkinson, Mark -- Williamson, Elizabeth A -- Xie, Feng -- Young, Bruce E -- Akcakaya, H Resit -- Bennun, Leon -- Blackburn, Tim M -- Boitani, Luigi -- Dublin, Holly T -- da Fonseca, Gustavo A B -- Gascon, Claude -- Lacher, Thomas E Jr -- Mace, Georgina M -- Mainka, Susan A -- McNeely, Jeffery A -- Mittermeier, Russell A -- Reid, Gordon McGregor -- Rodriguez, Jon Paul -- Rosenberg, Andrew A -- Samways, Michael J -- Smart, Jane -- Stein, Bruce A -- Stuart, Simon N -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1503-9. doi: 10.1126/science.1194442.
