In the photo above of the Connecticut College forest, notice how straight the trees are on this reforested pasture—a forester’s and farmer’s delight! The large tree in the foreground is a native species, a Chancho tree. To the far left is a Klinkii tree absorbing the sunlight that passes through the main canopy, part of the forest’s design. Other smaller trees are awaiting their turn to grow as RTT opens the forest with frequent, light thinnings for farmer income.
The nine-year-old deglupta hybrid tree in the photo to the left is part of the A-layer (above the B- and C-layers) of the specially designed forest. RTT developed the hybrid deglupta tree for its fast growth and other advantageous characteristics. Tall, straight and widely spaced, the deglupta tree has a light crown that allows light to filter through to the B-layer that contains several species. Not visible in this photo is the C-layer of Klinkii trees; the C-layer grows underneath the other trees to capture the remainder of the solar energy and increase total production in the forest. By judiciously managing this forest, RTT expects to maintain it intact indefinitely, extracting logs for farmer income while sequestering CO2 for Connecticut College.
RTT forests are measured annually and the information graphed to guide our new management techniques. The graph below is current though early 2019. The dip at 15 years indicates trees thinnings for farmer income and forest health. You can see the carbon capture was recovered in less than 3 years! So far this early RTT forest has captured 18.2 MT CO2e/year/hectare.
