Wildlife conservation policies directed at common and widespread, but
declining, species are difficult to design and implement effectively, as
multiple environmental changes are likely to contribute to population
declines. Conservation actions ultimately aim to influence demographic
rates, but targeting actions towards feasible improvements in these is
challenging in widespread species with ranges that encompass a wide range
of environmental conditions. Across Europe, sharp declines in the
abundance of migratory landbirds have driven international calls for
action, but actions that could feasibly contribute to population recovery
have yet to be identified. Targeted actions to improve conditions on
poor-quality sites could be an effective approach, but only if local
conditions consistently influence local demography and hence population
trends. Using long-term measures of abundance and demography of breeding
birds at survey sites across Europe, we show that co-occurring species
with differing migration behaviours have similar directions of local
population trends and magnitudes of productivity, but not survival rates.
Targeted actions to boost local productivity within Europe,
alongside large-scale (non-targeted) environmental protection across
non-breeding ranges, could therefore help address the urgent need to halt
migrant landbird declines. Such demographic routes to recovery are likely
to be increasingly needed to address global wildlife declines.
These are the mean site-level population trends for groups of migrant
(arid and humid-zone) and resident species derived from the PECBMS
data. We used data from 19 schemes in 17 countries covering 13,859 sites
and 80 species collected between 1994 and 2013.
This dataset contains the site-level estimates of population change
derived from the PECBMS data. We used data from 19 schemes in 17 countries
covering 13,859 sites and 80 species collected between 1994 and 2013. It
has 7 columns: Site: unique site id Trend: average population trend CIup:
upper confidence interval of the average population trend CIlo: lower
confidence interval of the average population trend Latitude: latitude of
the site Longitude: longitude of the site Status: the migratory status
(resident, arid or humid) of the trend
