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.”

Pluto should be reclassified as a planet, experts say

      The reason Pluto lost its planet status is not valid, according to new research from the University of Central Florida in Orlando. In 2006, the International Astronomical Union (IAU), a global group of astronomy experts, established a definition of a planet that required it to "clear" its orbit, or in other words, be the largest gravitational force in its orbit. […]
     Metzger, who is lead author on the study, reviewed scientific literature from the past 200 years and found only one publication -- from 1802 -- that used the clearing-orbit requirement to classify planets, and it was based on since-disproven reasoning.
     "It's a sloppy definition," Metzger said of the IAU's definition. "They didn't say what they meant by clearing their orbit. If you take that literally, then there are no planets, because no planet clears its orbit." […]
     Metzger said that the definition of a planet should be based on its intrinsic properties, rather than ones that can change, such as the dynamics of a planet's orbit. "Dynamics are not constant, they are constantly changing," Metzger said. "So, they are not the fundamental description of a body, they are just the occupation of a body at a current era."
    Instead, Metzger recommends classifying a planet based on if it is large enough that its gravity allows it to become spherical in shape. "And that's not just an arbitrary definition, Metzger said. "It turns out this is an important milestone in the evolution of a planetary body, because apparently when it happens, it initiates active geology in the body."
