Brazil nut tree
EndangeredBertholletia excelsa
Can live over 500 years and only fruits in intact forest, so a Brazil nut tree is a sign the ecosystem is whole again.

Para and Rondonia, Brazil
The forest that cools the world, replanted tree by tree.
The Amazon frontier runs across several Brazilian states. Batch 01 sits in Para, on land that was cleared decades ago and left to harden in the sun. We plant with Rioterra, based in Rondonia, with Agroforestree, and with local partners and farming families who collect the seeds and tend the plots. Every tree is placed by hand, mapped, and monitored.
The change
Today
Year 20How it grows

Year 1
Five trees and shrubs go in as one cluster.

Year 3
First shade, first fruit, soil starts holding water.

Year 20
Closed canopy, up to 3.5 tonnes of CO2 per tree.
Native species
Seeds are collected nearby and raised in local nurseries, so what grows back belongs to this place.

Swietenia macrophylla
Logged almost to disappearance across Rondonia. Every one we plant is a return.
Euterpe oleracea
Feeds families through the year and gives the young forest its first economic value.
Dipteryx odorata
Deep-rooted and drought-resistant, it holds the soil together while the canopy closes.
Handroanthus serratifolius
Flowers gold across the whole crown, visible from the air when the forest is coming back.
From the field

20 August 2026
This block in Rondonia was planted on former cattle pasture and now borders standing rainforest on two sides. The pioneer species have closed most of the canopy, which shades out invasive grass and keeps the soil moist through the dry months. Acai and cacao are growing underneath, and the access track on the west side is the route the crew uses for monitoring and harvest. The same planting model runs in Para, so members hold trees across both states.
