For the past five years, a group of villagers in the delta of the Irrawaddy River in Myanmar has painstakingly planted 2.7 million mangrove trees in an attempt to begin to restore an ecosystem that has been disappearing for decades. But the work is laborious, and the local nonprofit guiding the work wants to cover a much larger area–so they’re now turning to tree-planting drones.
The drones, from the startup BioCarbon Engineering, can plant as many as 100,000 trees in a single day, leaving the local community to focus on taking care of the young trees that have already started to grow. In September, the company will begin a drone-planting program in the area along with Worldview International Foundation, the nonprofit guiding local tree-planting projects. To date, the organization has worked with villagers to plant an area of 750 hectares, about twice the size of Central Park; the drones will help cover another 250 hectares with 1 million additional trees. Ultimately, the nonprofit hopes to use drones to help plant 1 billion trees in an even larger area.
The drone technology works in stages. As a first step, mapping drones fly more than 300 feet over the land, collecting detailed data about the topography and soil quality. An algorithm uses that data to choose the best locations to plant trees, and the best species to plant. Next, a second group of drones, flying low over the ground, automatically follows the map to plant seeds in custom, nutrient-filled “seed pods” designed by plant scientists to support each species; each drone can carry a mix of different species simultaneously. The drones fire the pods quickly enough to penetrate the soil.
The process targets locations for planting a seed within centimeters. “We can modify what to plant, and where, so you have the highest chance of survival,” says Irina Fedorenko, cofounder of BioCarbon Engineering, who initially connected with the founder of Worldview International at a conference. “If you do aerial spreading–you just spread seeds wherever–maybe they hit a rock, maybe they hit a swamp, and they’re not going to survive. But we can basically control for that.”
Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
