Percentage of time-series (= populations) of each habitat-specialist species that declined between the first and the last year of their monitoring period between 2000 and 2007.

<p>This time period spans the apparent partial recovery of specialist species in the early 2000s (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126004#pone.0126004.g002" target="_blank">Fig 2A</a>). The total number of time-series by habitat-specialist species is indicated in parentheses. The 72 species are ranked from the highest to the lowest percentage of declining time-series. Habitat-specialist species with 50% or more of declining time-series (black bars), and less than 50% (grey bars) are identified. In total, 557 populations declined, 446 increased and 64 were stable (no change). Note that this figure does not show the magnitude of the changes.
