Drones have spent the last few years quietly taking over jobs nobody wanted to do up close. They photograph hurricane damage, sniff out gas leaks, drop packages on porches, and patrol stretches of water no boat can sit on for a hundred days straight. The list keeps growing, and most of it is the kind of work that is either boring or mildly dangerous. Then a Swedish company sent one into a real forest, and it did something else entirely. It went and did a lumberjack’s job, with nobody at the controls.<\/p>\n
On May 22, the Uppsala-based startup AirForestry said its electric drone had felled a tree and flown the trunk clear of a working production forest, with no ground machine anywhere in the stand. The company is calling it the world’s first autonomous tree harvest in a real forest, and the people backing it are not hedging on the language. It is a genuinely strange thing to watch, and it points at one of the deadliest jobs on the planet.<\/p>\n
Here is where precision matters, because the headline version flattens two separate achievements into one and the real story is more interesting than the compressed one.<\/p>\n
AirForestry hit two milestones. First, its drone felled trees in an actual production forest, the messy, uneven, real-world kind rather than a tidy demo plot. Second, and separately, it ran a full autonomous sequence on its test field: the drone flew to position, identified the right tree, delimbed it, cut it, and dropped it off, with no human steering any of it. The company laid this out plainly on its own blog, framing the two as distinct proof points that together validate the system both in controlled conditions and out in the kind of forest it was built for.<\/p>\n
So the cleanest way to say it is this. The machine can do the whole job by itself, and the machine works in a real forest. AirForestry has now shown both, which is why the people involved are willing to use the phrase “world first” out loud. Alex Bakir, a general partner at Norrsken Evolve, one of the firm’s backers, told the forestry trade outlet Wood Central<\/a> the drone harvested a tree “on its own,” calling it the first of its kind anywhere.<\/p>\n What it is not, yet, is a fleet of robot lumberjacks clearing your local woods. It is a demonstration. A big one, but a first step.<\/p>\n To understand why a flying chainsaw is worth paying attention to, you have to sit with how bad the human version of this job is.<\/p>\n The U.S. Bureau of Labor Statistics released its latest workplace fatality data on February 19, covering 2024. Across every occupation in the country, the average was 3.3 deaths per 100,000 full-time workers<\/a>. Logging sits in a different universe. Researchers at the University of Washington’s regional safety center put the recent average for loggers at around 84 deaths per 100,000 workers, which is roughly 23 times the national rate, and that figure already reflects years of steady improvement. It used to be worse.<\/p>\n The reasons are not mysterious. You are working on slopes, often in bad weather, around chainsaws and heavy equipment, next to trees that weigh several tons and do not always fall where you want them to. A tree that hangs up, kicks back, or rolls the wrong way does not give you a second chance. The whole appeal of AirForestry’s pitch is that it takes the human and moves them out of the one place where all of that happens: under the tree.<\/p>\n That is the part worth holding onto. A drone that grips, cuts, and carries doesn’t just make the work faster. It empties out the spot on the ground where loggers get killed.<\/p>\n The hardware is not subtle. AirForestry’s drone is a 6.2-meter carbon-fiber airframe running on a fully electric powertrain, and it flies above the canopy rather than driving through it. There are no wheels, no tracks, and nothing touching the soil.<\/p>\n The cutting work happens through a purpose-built harvesting tool that hangs below the airframe on a line. It grips the tree near the top, delimbs it on the way down, cuts it close to the ground, and then the drone lifts the trunk out and flies it to the nearest road. The tool does the violence; the drone does the flying and the hauling.<\/p>\n The numbers around what it can lift tell you what it’s for. The drone can carry 200 kilograms, which sits comfortably above the 40-to-140-kilogram range of the thinning-grade trees it is designed to pull. This is not a machine for taking down old-growth giants. It is built for thinning, the routine work of removing the right smaller trees so the ones left behind grow faster and straighter. And it is engineered for the place it was born: it is rated to operate down to minus 20 degrees Celsius, through rain and snow, in wind gusts up to 13 meters per second. That is a Nordic thinning season, described in spec-sheet form.<\/p>\n If the pitch were only about keeping loggers alive, that would be enough. But AirForestry is leaning just as hard on the ground itself.<\/p>\n Conventional thinning works by driving a machine that weighs 20 tonnes or more deep into a stand to remove trees that can weigh as little as 80 kilograms. Getting that machine into position chews up the forest floor, and AirForestry estimates more than 20 percent of it gets damaged in the process: soil compaction, crushed roots, wheel ruts that take years to heal. A drone flying over the canopy leaves none of that behind. No tracks, no compaction, no root damage.<\/p>\n The economics are not small either. Forest owners worldwide spend something like 14 billion euros a year on thinning, according to figures AirForestry shared with Dronewatch Europe<\/a>. The company also claims its method yields around 8 percent more timber across a full harvest cycle, and that pulling heavy machinery out of Swedish thinning alone would keep 23 million tonnes of carbon dioxide locked in standing trees rather than disturbed ground. Those last numbers come from the company, so take them as the case it is making rather than independent findings, but the direction is clear enough.<\/p>\n Drones doing the dangerous, slow, or unreachable work is becoming a pattern across industries. The U.S. Coast Guard just put autonomous orange sail drones on Lake Erie to watch the maritime border with Canada<\/a> for stretches no cutter can manage. Japan is building deep-sea drones to mine rare earths<\/a> 6,000 meters down. Defense agencies are fielding underwater robots that sit on the seabed guarding cables and pipelines<\/a>. Forestry is just the latest place where the math of “send a robot instead” started to work. After watching cables and hunting submarines, the drones came for the chainsaw.<\/p>\n A single drone felling a single tree, and a separate clean run on a test field, is a long way from a working business. AirForestry knows it, and has been fairly open about the gap.<\/p>\n The operation the company is actually building toward is six aircraft thinning one stand at once, each flying autonomously. That fleet configuration is the point where AirForestry says the cost of airborne thinning finally matches the ground-based machinery it wants to replace, and it is the basis for the commercial rollout it is now preparing. One drone proves the concept. Six drones, working together without stepping on each other, prove the business.<\/p>\n The money and the muscle are starting to line up. AirForestry raised a 10.3 million euro seed round led by Northzone late in 2024, and Caroline Walerud, a co-founder, took over as chief executive in December 2025 to push the company into a scale-up phase. More telling, four of Sweden’s largest forest owners, Holmen, SCA, Stora Enso, and Sveaskog, have put 20 million Swedish kronor behind a joint project<\/a> to test and adapt the system in live operations. When the companies that own the forests are paying to help build the thing that changes how their forests get cut, that is a signal worth more than any press release.<\/p>\n None of that makes a logger redundant tomorrow. What AirForestry has shown is that the most dangerous spot in forestry, the patch of ground directly under a falling tree, no longer strictly needs a person standing in it. Whether that scales into a real fleet or stays an impressive demo is the part that gets decided over the next few seasons, in actual stands, in actual Nordic winters. The first tree is down. The hard part is the next ten thousand.<\/p>\n","protected":false},"excerpt":{"rendered":" Drones have spent the last few years quietly taking over jobs nobody wanted to do up close.
