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. 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. The preparation of this synopsis was funded by the Natural Environment Research Council and Arcadia.

Global evidence for the effects of interventions

Bird Conservation

This synopsis covers evidence for the effects of conservation interventions for native farmland wildlife. It is restricted to evidence captured on the website www.conservationevidence.com. The list of interventions was organized into categories based on the IUCN classifications of direct threats and conservation actions.

Evidence for the Effects of Interventions in Northern and Western Europe

Farmland Conservation

Does the creation of artificial reefs benefit subtidal benthic invertebrates? Is the use of organic farming instead of conventional farming beneficial to bat conservation? Does installing wildlife warning reflectors along roads benefit mammal conservation? Does the installation of exclusion and/or escape devices on fishing nets benefit marine and freshwater mammal conservation? What Works in Conservation has been created to provide practitioners with answers to these and many other questions about practical conservation. This book provides an assessment of the effectiveness of 2526 conservation interventions based on summarized scientific evidence. The 2021 edition containssubstantial new material on bat conservation, terrestrial mammal conservation and marine and freshwater mammals, thus completing the evidence for all mammal species categories. Other chapters cover practical global conservation of primates, amphibians, bats, birds, forests, peatlands, subtidal benthic invertebrates, shrublands and heathlands, as well as the conservation of European farmland biodiversity and some aspects of enhancing natural pest control, enhancing soil fertility, management of captive animals and control of freshwater invasive species. It contains key results from the summarized evidence for each conservation intervention and an assessment of the effectiveness of each by international expert panels. The accompanying website www.conservationevidence.com describes each of the studies individually, and provides full references. This is the sixth author-approved edition of What Works in Conservation, which is revised on an annual basis.

What Works in Conservation

Silviu O. Petrova

Is reduced tillage in arable fields beneficial for farmland biodiversity? Is prescribed burning in grasslands beneficial for bird conservation? Does livestock exclusion from degraded peatlands benefit peatland conservation? Is the provision of artificial shelters effective for subtidal benthic invertebrate conservation? Do wind turbine modifications reduce bat fatalities? Does adding topsoil increase the abundance of heathland plants? Are interventions to reduce road impacts on amphibians effective? Do herbicides control invasive parrot's feather? What Works in Conservation has been created to provide practitioners with answers to these and many other questions about practical conservation. This book provides an assessment of the effectiveness of conservation interventions based on summarized scientific evidence. The 2020 edition contains new material on mammals, birds, marine benthic invertebrates, bat conservation and wetlands. Other chapters cover practical global conservation of primates, peatlands, shrublands and heathlands, management of captive animals as well as an extended chapter on control of freshwater invasive species, the global conservation of amphibians, bats, birds and forests, conservation of European farmland biodiversity and some aspects of enhancing natural pest control, enhancing soil fertility and control of freshwater invasive species. It contains key results from the summarized evidence for each conservation intervention and an assessment of the effectiveness of each by international expert panels. The accompanying website www.conservationevidence.com describes each of the studies individually, and provides full references. This is the fifth edition of What Works in Conservation, which is revised on an annual basis. Arcadia, DEFRA, ESRC, MAVA Foundation, NERC, Natural England, Robert Bosch Stiftung, Synchronicity Earth, South West Water and Waitrose Ltd. have generously contributed towards the publication of this volume.

This synopsis covers evidence for the effects of conservation interventions for native farmland wildlife. It is restricted to evidence captured on the website www.conservationevidence.com. It includes papers published in the journal Conservation Evidence, evidence summarized on our database and systematic reviews collated by the Collaboration for Environmental Evidence. It is the thrid volume in the series Synopses of Conservation Evidence. Evidence was collected from all European countries west of Russia, but not those south of France, Switzerland, Austria, Hungary and Romania. A list of interventions to conserve wildlife on farmland was developed collaboratively by a team of thirteen experts. A number of interventions that are not currently agri-environment options were added during this process, such as ‘Provide nest boxes for bees (solitary or bumblebees)’ and ‘Implement food labelling schemes relating to biodiversity-friendly farming’. Interventions relating to the creation or management of habitats not considered commercial farmland (such as lowland heath, salt marsh and farm woodland) were removed. The list of interventions was organized into categories based on the International Union for the Conservation of Nature (IUCN) classifications of direct threats and conservation actions. Interventions that fall under the threat category ‘Agriculture’ are grouped by farming system, with separate sections for interventions that apply to arable or livestock farms, or across all farming types.
