<p>This book brings together scientific evidence and experience relevant to the practical conservation of wild birds. The authors worked with an international group of bird experts and conservationists to develop a global list of interventions that could benefit wild birds. </p><p>For each intervention the book summarises studies captured by the Conservation Evidence project where that intervention has been tested and its effects on birds quantified. The result is a thorough guide to what is known or not known about the effectiveness of bird conservation actions throughout the world.</p><p>The preparation of this synopsis was funded by the Natural Environment Research Council and Arcadia.</p>
