Reforest The Tropics

An applied research program demonstrating climate change mitigation through sustainable farm forestry

Incorporating Mahogany

0

A historical challenge with reforestation has been convincing
local landowners to participate. Since most degraded land isshootborer
held in private hands, programs must incentivize the owners of
that land to reforest. RTT has generated landowner interest by
working towards making forestry economically competitive
with other land-use options. RTT mixtures are configured to
capture large quantities of CO2, however, more importantly,
the forests are also designed to keep that CO2 stored away
for the long term by paying attention to local needs.
RTT has experimented with the inclusion of mahogany (Swietenia macrophylla) in its mixtures
for decades. Although mahogany does not grow as fast as some other species in the RTT
matrix, it offers a unique advantage by adding to the overall sustainability of the program. The
presence of mahogany, a coveted species after centuries of exploitation, inherently increases
the value of the program to landowners. The increased value of the program is translated into
more attention and management by the landowners, which leads to a more sustainable program.
Mahogany is rarely incorporated into forest plantations due to its susceptibility to attack from
the shootborer (Hypsipyla grandella), a pest that damages the growth and form of the species.
Through trial and error, RTT developed a treatment protocol that protects the trees from attack
and allows for their inclusion as a complementary species to the other trees that excel at carbon
capture and storage. Our research continues…
