Achieving ambitious global restoration commitments is a huge challenge. The Atlantic Forest Restoration Pact, created in 2009 as a movement to restore 15M ha of degraded/deforested lands by 2050, pledged 1M ha towards the 2020 Bonn Challenge. We documented the restoration of an estimated 673,510–740,555ha of native forests from 2011 to 2015 in the Atlantic Forest, and expect that a total of 1.35–1.48M ha will be under recovery by 2020. The Pact is one of the first Brazilian restoration initiatives to monitor an international restoration commitment and to demonstrate that ambitious targets can be reached. Part of this success in large -scale restoration is related to three main Pact activities: (i) development of restoration governance, communication and articulation;(ii) promotion of strategies to influence public policies; and (iii) establishment of restoration monitoring systems. The experience and lessons learned by the Pact could inspire and inform other restoration initiatives worldwide.
