Ecosystem restoration is crucial worldwide to address environmental challenges. Many countries, including Brazil, have committed to restoring degraded landscapes at national and international levels. Brazil aims to restore twelve million hectares of degraded areas by 2030, which requires strategic decision-making to allocate resources effectively and balance biodiversity gains with societal benefits.

The modeling approach presented in this paper uses extensive biodiversity field data to identify priority areas for restoration across Brazil’s diverse phytogeographic domains. By focusing on expanding native species habitats and enhancing connectivity, the authors aim to maximize ecological returns. Precisely, they pinpoint areas within each Brazilian phytogeographic domain with the greatest potential for habitat enhancement, including the Amazon’s arc of deforestation, central Cerrado, the limits of Caatinga, Pampa, and Pantanal, and the coastal areas of the Atlantic Forest.

Restoring 30 % of these areas—approximately 76 million hectares—could significantly benefit 11,028 species by increasing available habitat by up to 10 % and improving landscape functional connectivity by 60 %. Moreover, this restoration effort would capture up to 9.8 million tons of atmospheric carbon, contributing to global climate goals.

As Brazil strives to meet national and international targets, the authors also advocate for economic incentives to support restoration practices within each phytogeographic domain. Integrating prioritization modeling into decision-making ensures optimal biodiversity and carbon stock outcomes to guide more effective restoration efforts. This comprehensive strategy helps advance restoration goals and underscores the vital role of science-based planning in safeguarding our planet’s natural heritage.
