Trees that can walk up to 20m per year

It takes a whole day to travel from Ecuador’s capital, Quito, to the heart of the Unesco Sumaco Biosphere Reserve, some 100km to the southeast. The journey entails three hours by car to the edge of the forest, and then anywhere from seven to 15 hours by boat, mule and foot, mostly uphill and on a muddy road, to reach the interior.
