Staff from Reforest The Tropics, Inc., making measurements on some 8-year old trees in Costa Rica. The worker is measuring the upper diameters of these Chancho trees to be able to accurately calculate their form class, volume and carbon content. Trees do really grow faster in the tropics!
These trees are due for thinning in October, 2008. The RTT Model of carbon-offset forests includes thinnings of forests for farmer income as a way to make the forests sustainable. Sustainability is the key to long-term, indefinite carbon storage in forests.
