The acquisition of land from regular tree donations is excluded. Anyone who wants land to be acquired from their donations must send Plant-for-the-Planet a so-called earmarked donation for land. Fortunately, we were able to acquire our 91-hectare research area in Constitución in 2019 due to such a donation. Here, our ecologists are conducting pioneering research under the scientific supervision of Imperial College, London and ETH, Zurich. In 2021, we were also able to acquire more than 1,000 hectares of additional land through such generous donations.
