Performance of alternative allocation schedules.

<p>The conservation outcomes delivered by different allocation schedules, both measured relative to a null model of no management investment. (A) Annual provision of additional ecosystem services from mangrove conservation in Sabah under the optimal allocation (restoration-only, blue line), and the standard, protection-only approach (green line). Performance is measured relative to the amount of coastal defence that would be expected in the absence of management intervention. (B) Extinctions averted by the optimal allocation schedule, which switches from protection to restoration after 20 years (dashed black line). Results are also shown for the standard, protection-only approach (green line), and a restoration-only approach (blue line). The number of observed extinctions is reported in comparison to the number of extinctions we would expect in the absence of management intervention.

Allocation schedules for mangrove ecosystem service provision.

<p>Proportion of landscape in each land state over a 30-year mangrove conservation project in Sabah. Results show (A) the optimal allocation decision to only restore, and (B) the standard approach of pursuing protection while intact habitat remains unprotected. Prioritising restoration results in fewer protected areas (green) and a greater amount of unprotected intact habitat (grey), but has greater success limiting the amount of degraded land (red), therefore maximising the provision of ecosystem services (see <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002052#pbio.1002052.g002" target="_blank">Fig. 2A</a>). The data used in this figure is given in <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002052#pbio.1002052.s001" target="_blank">S1 Data</a>, and the Matlab code that generated it can be found in <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002052#pbio.1002052.s022" target="_blank">S2 Text</a>.</p

Allocation schedules for rainforest biodiversity conservation.

<p>Proportion of landscape in each land state through time over 43 years of rainforest conservation in Paraguay’s Atlantic Forest (1970–2013). Results show (A) the optimal allocation schedule of protection for 20 years, followed by 23 years of restoration, and (B) the standard approach of protection while intact habitat remains unprotected. An early switch from protection to restoration results in fewer protected areas (green) and more unprotected habitat (grey), but less degraded land (red). The result is fewer species extinctions (see <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002052#pbio.1002052.g002" target="_blank">Fig. 2B</a>). The data used in this figure is given in <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002052#pbio.1002052.s003" target="_blank">S3 Data</a>, and the Matlab code that generated it can be found in <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002052#pbio.1002052.s023" target="_blank">S3 Text</a>.</p

Dynamics of the unified restoration and protection model.

<p>Schematic representation of the landscape dynamics described by <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002052#pbio.1002052.e007" target="_blank">Eq (7)</a>. Arrows show the direction of state changes between the four land states, with the mathematical terms indicating the magnitude of the flux. For example, the blue arrow extending from restoring land (R) to degraded land (C) indicates that the process of restoration moves land from the “degraded” state to the “restoring” state.</p
