Written in partnership with the Conservation Evidence project, What Works in Conservation (WWIC) is an essential reference guide that summarizes and evaluates the latest scientific evidence on over a thousand conservation interventions. The 2018 edition (available here) includes chapters covering practical global conservation of primates, amphibians, bats, birds, forests, peatlands, shrublands and heathlands, as well as the management of captive animals, control of freshwater invasive species, and ways to improve farmland biodiversity, natural pest control, and soil fertility.
WWIC uses panels of experts to assess conservation effectiveness according to the following categories: Beneficial, Likely to be beneficial, Trade-off between benefit and harms, Unknown effectiveness, Unlikely to be beneficial, and Likely to be ineffective or harmful. As an example, here are some bird conservation interventions categorized as beneficial or likely to be beneficial:
I’m hoping future WWIC editions will address conservation efforts to protect insect pollinators. In the meantime, there’s always the Conservation Evidence website, which summarizes the evidence so far on 59 different types of interventions to help bees.
