Re-Planting a Forest, One Drone at a Time
That funny little buzz you hear in the forest may not just be the hum of summer insects. In the near future it could be a small fleet of drones, coming to replant and restore forests that have been stripped of trees by industrial-scale deforestation. It’s all part of an ambitious plan by BioCarbon Engineering, a U.K.-based startup on a global mission to battle widespread clear-cutting, which strips more than 26 billion trees off the planet each year. CEO Lauren Fletcher, who spent 20 years as an engineer with NASA, says the only way to fight industrial-scale deforestation is with industrial-scale reforestation. Their idea: plant 1 billion trees a year. The first targets are in South Africa and the Amazonian jungles, both of which have suffered from widespread forest eradication.
BioCarbon’s reforestation scheme is simple and efficient. Here’s a quick look at how it plans to deploy its drone fleet:
1 Do a 3-D aerial survey. First, drones are sent to fly over a potential planting zone, snapping photos that create 3-D maps of the area to be reforested. The number of drones will vary depending up on the size of the seeding.
2 Create a seeding plan. Once all that terrain data has been analyzed, it then generates a seeding pattern that best suits the terrain.
3 Load the seed pods. The drones, which are equipped with guidance and control software, carry pressurized canisters of seed pods with germinated seeds immersed in a nutrient-rich gel.
4 Hover and plant. Flying at a height of 1 or 2 meters, the drones follow the planting patterns, firing the biodegradable seed pods down to the ground. The pods break open upon impact, allowing the germinated seed a chance to take root.
5 Monitor growth. After planting, the drones do low-level flights to assess the health of the sprouts and saplings.
Such “precision forestry,” as BioCarbon calls it, is extremely efficient. A farmer might hand plant as many as 3,000 seeds a day; Fletcher says his drones can drop up to 36,000 seed pods daily, often in areas where a human can’t reach. Working with local ecologists, BioCarbon will use the drones to spread a variety of tree species, as well as microorganisms and fungi designed to improve the soil quality. “The central focus is ecosystem restoration,” Fletcher says.
On a planetary climatological scale, Morton notes that “tropical deforestation plays a big role in global climate cycles,” claiming the accelerated pace of cutting and burning of forests accounted for 20 percent of greenhouse gas emissions in the 1990s. Fletcher and his team want to help reverse that trend. “By planting at the scale we’re looking at,” he says, “we can make a real longterm impact. We hope to do a lot of good in the world.”

A estrela cadente Me caiu ainda quente Na palma da mão (Paulo Leminski)
Nas mãos inspiradas nascem antigas palavras com novo matiz (Helena Kolody)
Fortunato saiu, foi deitar-se no sofá da saleta contígua, e adormeceu logo. Vinte minutos depois acordou, quis dormir outra vez, cochilou alguns minutos, até que se pegue e voltou à sala. Caminhava nas pontas dos pés para não acordar a parenta, que dormia perto. Chegando à porta, estacou assombrado. Garcia tinha-se chegado ao cadáver, levantara o lenço e contemplara por alguns instantes como feições defuntas. Depois, como se a morte espiritualizasse tudo, inclinou-se e beijou-a na testa. Foi nesse momento que Fortunato chegou à porta. Estacou assombrado; não podia ser o beijo da amizade, podia ser o epílogo de um livro adúltero. Não tinha ciúmes, note-se; a natureza compô-lo de maneira que lhe não deu ciúmes nem inveja, mas dera-lhe vaidade, que não é menos cativa ao ressentimento. Olhou assombrado, mordendo os beiços. Entretanto, Garcia inclinou-se ainda para beijar outra vez o cadáver; mas então não pôde mais. O beijo rebentou em soluços, e os olhos não puderam conter como lágrimas, que predomina em borbotões, lágrimas de amor calado, e irremediável desespero. Fortunato, à porta, onde ficara, saboreou tranquilo essa explosão de dor moral que foi longa, muito longa, deliciosamente longa. (Várias Histórias - Machado de Assis - WM Jackson Inc Editores - 1946.)
