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. The accompanying website www.conservationevidence.com describes each of the studies individually, and provides full references

Rainfall on wintering grounds affects population change in many species of Afro-Palaearctic migrants
Survival and population growth rates in several species of Afro-Palaearctic migrant have been shown to correlate with rainfall regimes and/or vegetation level on their African wintering grounds, implying that seasonal food resources may contribute to population limitation. Here we explore the generality of this relationship across 16 migrant species breeding in England by investigating the proportion of variability in annual population change that is explained by the impact of environmental variables on wintering and staging grounds over 25- and 40-year time periods. In the 40-year time-series, rainfall in the arid Sahel region of West Africa had the strongest and most consistent effects on migrant populations, positively influencing the population growth rate in six of nine species which winter in this area and in three of seven species that use the region during their migratory passage but which over-winter further south. The effects of precipitation in other regions of Africa and satellite-derived measures of vegetation quality in all regions were weaker and less consistent in direction. Over the 25-year period for which data on both rainfall and vegetation were available, 12 of the 16 study species showed significant weather effects; the mean deviance explained by environmental variables among these 12 species was 32 %, increasing to 41 % when density-dependence was added to the models. For the 40-year time period, 11 species showed significant effects of rainfall, with the mean deviance explained by environmental variables of 14 % (23 % including density-dependence). Our results demonstrate that in many long-distance migrant species, precipitation in the Sahel is a significant driver of changes in abundance at the large-scale population level.</p
