During years of researching on the ground in rainforests, Houlihan has seen how the building of roads and bridges, pitched as an infrastructure gain to local communities, are usually for the benefit of companies and governments often foreign companies and governments to mine, extract and poach valuable resources. Eventually, he began visiting Shinto sites and observing their chinju no mori, or sacred shrine forests. Miyawaki determined that these were time capsules, showing how indigenous forest was layered together from four categories of native plantings: main tree species, sub-species, shrubs, and ground-covering herbs.

(When planting his backyard forest, Sharma accidentally introduced two non-native speciesneither he nor his source knew any better at the timeso he includes detailed instructions to help others avoid this mistake.) This initiative piggybacked onto earlier efforts from various international players to commit countries to saving and creating forests; the goal of the Bonn Challenge now is to restore 350 million hectares of degraded land by 2030 by planting millions of trees. For a period of two to three years, the site is monitored, watered, and weeded, to give the nascent forest every chance to establish itself. Accordingly, methods to accelerate forest recovery must address multiple impediments.
