The drone-assisted rainforest seeding technology in Brazil has achieved remarkable results, with a survival rate exceeding 60% compared to manual planting
2025,08,13
The drone seeding technology employed by the Brazilian rainforest conservation organization "Green Horizons" is bringing new hope to the restoration of the Amazon rainforest. This technology utilizes a specially designed ejection device to precisely deliver tree seeds wrapped in nutrient-rich matrices to designated areas. The matrices contain water-retaining agents and antifungal agents, providing three months of growth protection for the seeds.
Test data shows that the survival rate of tree seeds sown by drones reaches 72%, significantly surpassing the 45% of those planted manually. The operational efficiency has also been increased by 8 times - a single drone can sow 12,000 seeds per day, covering an area of 20 hectares. Carlos Mendes, the project coordinator, explained: "We have selected 12 local tree species such as Brazil nut trees and rosewood. The seed shells have undergone special treatment to resist insect feeding. The terrain sensors equipped on the drones can automatically avoid steep slopes and waterlogged areas, ensuring that the seeds fall in the best growth position."
Since its launch in 2023, the project has restored 1,200 hectares of rainforest using drones. Monitoring shows that the newly planted saplings have an average height of 1.8 meters, attracting 37 species of birds and 12 species of mammals to return. The Brazilian Ministry of Environment has approved the expansion of the project to 5,000 hectares and provided financial support of 4.5 million reais. Mendes said, "We are testing nighttime sowing patterns, using infrared cameras to identify the distribution of mature trees, so that the growth environment of new saplings is closer to the natural rainforest structure."
