New drone tech that can plant trees 10 times faster than humans
Experts say global reforestation is one of our best defences against climate change, so a Toronto-based company is developing drones that can get the job done quickly
EEvery summer, thousands of people take to the mountain slopes of British Columbia to plant tree seedlings, restoring forests cut down for commerce. It’s backbreaking, dangerous work, as Bryce Jones learned during his summer of tree planting in 2013. The experience left him wondering: why hasn’t the technology of tree-planting evolved at the same pace as the technology of tree-cutting?
“Humans plant trees without any technology but shovels, and that hasn’t changed since the origin of tree planting,” he says. Yet the need for rapid reforestation has never been greater: earlier this year, the CBC reported that B.C. will have to plant an estimated 48 million more trees in 2020 than it did in 2019 to restore areas lost to record-breaking wildfires. And according to a 2019 study by a group of European researchers, humanity’s current best hope for avoiding a catastrophic increase in global temperatures is to restore about a billion hectares of forest worldwide for carbon sequestration.
Jones, who has a degree in biology from the University of Victoria and also studied mechatronic engineering, believes drones are the most efficient and economical solution. His company, Toronto-based Flash Forest, has developed a mechanism that will enable a drone to fire specially designed seed pods into the soil at a rate of 10,000 to 20,000 trees per day — 10 times faster than a human planter.
A Kickstarter campaign to raise startup capital for Flash Forest went live in December 2019. It was fully funded within 24 hours and has since raised more than $100,000 — more than enough for Jones and his team to purchase the equipment they need to automate pod production. That will drastically reduce the cost per pod, Jones says, and allow Flash Forest to increase the number of trees they can plant. The company has already received huge interest from the forestry sector in Canada and beyond.
“With this technology we’re able to bring the costs down significantly, accelerate the rate of reforestation, and potentially revolutionize the entire industry.”
FIRE AWAY
The pods are fired into the ground from a height of two to three metres at a speed of 90 metres per second. The height and speed can be adjusted for soil condition — lower speed in very moist conditions, higher in dry conditions.
POD POWER
Each pod consists of several pregerminated seeds, plus a mixture of symbiotic fungi, fertilizers, and something Jones calls the “secret sauce.” The pods can be customized for virtually any tree species and ecosystem.
EYES IN THE SKY
Flash Forest is experimenting with multispectral mapping — also by drone — to identify the best sites for replanting and to monitor growth on replanted sites year over year.
FOREST VS. TREES
Flash Forest aims to plant a variety of different species on each site. “We’re committed to full ecosystem recovery,” says Cameron Jones, Bryce’s brother and an adviser for Flash Forest. “We don’t want to plant monocultures; we’re trying to emphasize biodiverse ecosystems with everything from the right grasses to the right canopy growth.”
