Resumo: Aiming to subsidize actions and policies for the development of large-scale restoration in Brazil, the Institute for Applied EconomicResearch and The Nature Conservancy, started an important study to estimate the costs of implementing key ecologicalrestoration techniques in regions of Brazil. The project also has the support of the Brazilian Agricultural Research Corporation(EMBRAPA), the Brazilian Ministry of the Environment (MMA) and the Deutsche Gessellschaft fur Internationale Zusammenarbeit(GIZ). Initially we identified widely used techniques by consulting executives from restoration projects, further characterizingeach in terms of required management activities, steps and inputs. Recognizing that initial site conditions play a role in restorationcosts, we define two hypothetical scenarios presuming two levels of intervention necessity: Favorable EnvironmentalConditions ? FEC and Unfavorable Environmental Conditions - UEC. Next, we estimated costs for acquisition of each input and executionof each management activity based on data collected from establishments in the restoration sector. The estimated averagecost of restoration (US$/hectare) for evaluated techniques considering both FEC and UEC scenarios is, respectively: densetree planting of several species through seedling: US$ 2,271 and US$ 6,081; dense tree planting of several species through seed:US$ 2,966 and US$6,727; density-improvement tree planting through seedling/enrichment planting through seedling: US$960and US$3,323; density-improvement tree planting through seeds/enrichment planting through seeds: US$172 and US$2,033; managementof advanced natural regeneration: US$301 and US$707. The great difficulty of collecting information (e.g. Pantanal andPampa biomes) highlights the necessity for discussions about ways to monitor restoration costs in Brazil.
