UAV seeding — the aerial broadcast or targeted delivery of tree and understory plant seeds by unmanned aerial vehicles — has emerged as a scalable, cost-competitive method for reforestation and ecological restoration over terrain that is difficult or dangerous to access on foot or by conventional aircraft. Systems range from simple payload-modified multirotors that release seeds through a hopper and spreader mechanism, to purpose-built fixed-wing and hybrid UAVs with high-capacity hoppers and variable-rate seed metering controlled by GIS prescription maps. More sophisticated approaches use pneumatic or mechanical "seed shooting" systems that embed seeds directly into the soil surface upon impact, improving seed-to-soil contact and germination rates compared to broadcast scattering. Seeds are often pre-treated with protective coatings containing hydrogels, rodenticides, fungicides, and nutrient primers to survive the rigours of aerial delivery and early establishment. Companies including AirSeed Technologies (Australia), DroneSeed (USA), and Droneseed competitors in Canada and Europe have demonstrated operational reforestation campaigns planting thousands to millions of seeds per day, at costs claimed to be significantly lower than helicopter broadcast or hand-planting. In Australia, AirSeed Technologies — headquartered in Sydney — has become a prominent player, conducting reforestation missions in post-fire landscapes, degraded agricultural land, and coastal dune rehabilitation sites across New South Wales and Queensland. Their system uses machine learning to identify the best microsites within a target area for seed delivery, improving establishment outcomes. Regulatory pathways under CASA's operational framework and the integration of UAV seeding into Australian Carbon Credit Unit (ACCU) methodologies under the Emissions Reduction Fund are active areas of policy development. Key challenges include seed predation, germination monitoring, species mix optimisation, and achieving the required seedling densities for carbon and biodiversity project compliance.
