What works in conservation? Using expert assessment of summarised evidence to identify practices that enhance natural pest control in agriculture.

This paper documents an exercise to synthesize and assess the best available scientific knowledge on the effectiveness of different farm practices at enhancing natural pest regulation in agriculture. It demonstrates a novel combination of three approaches to evidence synthesis-systematic literature search, collated synopsis and evidence assessment using an expert panel. These approaches follow a logical sequence moving from a large volume of disparate evidence to a simple, easily understandable answer for use in policy or practice. The example of natural pest regulation in agriculture was selected as a case study within two independent science-policy interface projects, one European and one British. A third funder, a private business, supported the final stage to translate the synthesized findings into a useful, simplified output for agronomists. As a whole, the case study showcases how a network of scientific knowledge holders and knowledge users can work together to improve the use of science in policy and practice. The process identified five practices with good evidence of a benefit to natural pest regulation, with the most beneficial being 'Combine trap and repellent crops in a push-pull system'. It highlights knowledge gaps, or potential research priorities, by showing practices considered important by stakeholders for which there is not enough evidence to make an assessment of effects on natural pest regulation, including 'Alter the timing of pesticide application.' Finally, the process identifies several important practices where the volume of evidence of effects on natural pest regulation was too large (>300 experimental studies) to be summarised with the resources available, and for which focused systematic reviews may be the best approach. These very well studied practices include 'Reduce tillage' and 'Plant more than one crop per field'.Elements of this work were funded by the European Commission under its 7th framework programme (BiodiversityKnowledge project, Grant number: 265299), the Natural Environment Research Council (NERC)'s Knowledge Exchange Programme on Sustainable Food Production (Grant code: NE/K001191/1) and Waitrose plc.

What Works in Conservation 2018

This book provides an assessment of the effectiveness of 1277 conservation interventions based on summarized scientific evidence. The 2018 edition contains new chapters covering 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. Other chapters cover 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.

Farmland Conservation : Evidence for the effects of interventions in northern and western Europe

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

Farmland conservation

This book is meant as a guide to the evidence available for different conservation interventions and as a starting point in assessing their effectiveness. The assessments are based on the available evidence for the target group of species for each intervention. The assessment may therefore refer to different species or habitat to the one(s) you are considering. Before making any decisions about implementing interventions it is vital that you read the more detailed accounts of the evidence in order to assess their relevance for your study species or system.Full details of the evidence are available at www.conservationevidence.comThere may also be significant negative side-effects on the target groups or other species or communities that have not been identified in this assessment.A lack of evidence means that we have been unable to assess whether or not an intervention is effective or has any harmful impacts

What Works in Conservation 2020

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 1614 conservation interventions based on summarized scientific evidence. The 2020 edition contains new material on bat conservation and our first marine chapter, on Subtidal benthic invertebrate conservation. 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 fourth edition of What Works in Conservation, which is revised on an annual basis
