Shade loving Trees Under the Canopy

We are very interested in species of trees that can fill in under our forests as we harvest/thin the larger trees. This is our approach to developing the RTT forest model that can achieve our goals of long-term income for the farmer, and carbon storage.  Here are examples from under-plantings of Gavilan in a 2010 forest. They are straight so far.

Gavilan as a species of trees that can fill in under our forests as we harvest/thin the larger trees forest is 2 1/2 years old.
Gradually, the Klinkiis under the Deglupta will expand upwards and to the sides. We
want a forest in which no sunlight reaches the forest floor, all of the solar energy captured
by the trees. These are still very young trees, doing very well.

Because we know the growth characteristics of these tree species, we can design forests that may better meet the stakeholders needs, namely, the sequestation needs of US emitters who sponsor forests, income for farmers on whose pastures we plant the forests, and the others such as wildlife and the rest of the biome..

Connecticut Municipal Electric Energy Cooperative CMEEC

The CMEEC 15-Acre Carbon-Offset Forest

In 2000, RTT partnered with the Connecticut Municipal Electric Energy Cooperative (CMEEC) to plant a 15-acre forest in Costa Rica to help offset carbon emissions created through CMEEC’s energy generation activities.  CMEEC is a publicly directed joint action supply agency formed by the state’s municipal electric utilities.

CMEEC Forest in Costa Rica, July 2008

CMEEC furnishes low-cost and reliable electric power by financing, acquiring and constructing generating resources and implementing power supply contracts.  Connecticut’s municipal utilities supply electric power to over 66,000 customers including some of the largest and most prominent industries in Connecticut.

Shown to the right is the 8-year old CMEEC forest ready to be thinned for farmer income. The remaining forest, after thinning, will continue to sequester and store the CO2 emissions from CMEEC’s office and vehicle emissions.  RTT measures most forests annually to calculate the sequestration rate in this applied research program.

RTT Staff Measuring Trees in a Costa Rican Carbon-Offest Forest

Shown left, RTT staff making measurements on some of the 8-year old trees in the CMEEC forest in Costa Rica.  The worker in the tree is measuring the upper diameters of the Chancho trees to be able to accurately calculate their form class, volume and carbon content.  Thinnings are an important part of the RTT Model of carbon-offset forests.  The RTT Model 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.
