U.S. firm deploys drones to replenish forests destroyed by wildfires Nathan Howes Sunday, December 13th 2020, 2:13 pm - According to DroneSeed, it can grow up to 140 trees per acre based on tests in New Zealand and Washington state. With a record-setting wildfire season blazing across the U.S., one company has found a possible solution for quickly regenerating the vast amount of lost forests. But Seattle-based DroneSeed believes it has an effective and efficient answer to the problem -- using fleets of drones (also referred to as drone swarms) to reforest burned-down areas by releasing "seed vessels" onto sections that have the best chances of re-populating.
