Using drones to plant 1 billion trees per year to tackle industrial-scale deforestation.

Forests are the most efficient way to remove carbon from the atmosphere, yet we’re moving in the wrong direction. Each year, we have a net loss of 6 billion trees. We need to reverse this trend and put ourselves on course to add up to one trillion trees over the rest of the century. 

Dendra enables faster, cheaper, more scalable restoration of the world's native forests so that we can turn the tide. Today, we work with mature, regulated industries that already pay to restore native ecosystems. We provide end-to-end ecosystem management, from ultra-high resolution monitoring to aerial seeding to automated environmental reporting. As more organizations engage in restoration, voluntarily or because of government regulation, we're best positioned to serve them.
