<p>Species' sensitivity scores are calculated as their niche breadth*reliance, with higher values indicating species less sensitive to changes in resource abundance or availability. Equivalent, PECBMS-only <i>BREAKPOINT</i> sets for the forest type and region indicators are presented in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s014" target="_blank">Table S7</a>. ‘0/1’ identifies species that were interchangeable in any given breakpoint set due to equal sensitivity scores – see specific note for each indicator for further details.</p><p><i>*Species also included in current pan-European forest bird indicator (for full list see</i><a href="http://www.ebcc.info/index.php?ID=459" target="_blank">http://www.ebcc.info/index.php?ID=459</a>).</p>a<p>Either species could be included.</p>b<p>Any one of three could be included.</p>c<p>Any two of three could be included.</p

Overview structure of SpecSel, the species' selection algorithm, outlining the process to identify the optimal indicator set for each set size.

Temporal dynamics of pan-European woodland bird indicator, drawn from species currently covered by PECBMS, between 1980 and 2011.

<p>Lines show index values, based on the geometric mean of constituent species' population trends, for <i>MINIMAL</i>, <i>BREAKPOINT</i>, <i>SENSITIVE</i>, the existing pan-European woodland bird index (<i>CURRENT</i>) and <i>COMMUNITY</i> sets. Equivalent figures for the regional and woodland type indicators are provided in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s002" target="_blank">Figures S2</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s003" target="_blank">S3</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s004" target="_blank">S4</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s005" target="_blank">S5</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s006" target="_blank">S6</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s007" target="_blank">S7</a>.</p

Relationship between the number of species in the indicator and the average sensitivity score of constituent species in the most sensitive combination for that set size for the pan-European and alternative indicators drawn from all possible species.

<p>Average sensitivity scores calculated as average of niche breadth*reliance across constituent species, with higher scores associated with less sensitive indicators. See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217.s001" target="_blank">Figure S1</a> for the equivalent figure for pan-European and alternative indicators drawn only from species currently covered by PECBMS.</p

Summary of comparisons between the temporal dynamics of alternative index sets (<i>MINIMAL</i>, <i>BREAKPOINT</i>, <i>SENSITIVE</i> and, for the pan-European and regional indicators, existing indicator sets <i>CURRENT</i>) for each indicator type and that of an index based on the population dynamics of all species in the candidate pool from which the sets had been drawn (<i>COMMUNITY</i>).

<p>Data presented are the slope (95% confidence interval) and correlation coefficient <i>r</i> of the relationship between the inter-annual changes of <i>COMMUNITY</i> and each alternative indicator set, derived using Type II major axis regression. Slope values less than one reflect greater inter-annual changes in the specific indicator relative to that of <i>COMMUNITY</i>. The 2011 index value for each alternative indicator is also shown. *P<0.05; **P<0.01; ***P<0.001; <i>ns</i> – not significant.</p>a<p>Calculated from the geometric mean of constituent species' population change between 1980 (1982 for East and 1989 for South) and 2011 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097217#pone.0097217-Gregory3" target="_blank">[13]</a>.</p
