BioCarbon says its two drones can plant 100,000 trees in a single day. It has started in Myanmar (previously called Burma) following successful trials in England and Australia, The drones work in three stages. Firstly the drones will map an area, analysing surface topology and composition, soil type and moisture, as well as possible physical obstructions. These analyses help decide which seeds should be planted. Secondly, the drones fly low, around 3-6 feet above the ground, planting new seeds every six seconds. The drones aren't however just letting the seeds drift in the breeze. Each drone uses a pressurised can to shoot a biodegradable seed pod into the ground. Thirdly, after the mapping and planting, the drones monitor the area regularly. That data gets fed into the company's machine learning algorithms, strengthening the mapping part of the plan. The process is ideal for reforesting after fires and planting trees in difficult to reach areas. https://www.biocarbonengineering.com/
