Community Forests of Rogho and Boala, Significant Carbon Sinks in the Center-West Region of Burkina Faso.

---

Résumé

This study aimed to evaluate the carbon stock potential of the
community forests of Rogho and Boala. The indirect method was adopted to
estimate the above and below-ground woody biomass, while the integral
collection method was chosen to estimate the herbaceous biomass. Data was
collected from 77 circular plots with a radius of 18m, which included the
diameter and height of plant species within these plots. The data analysis that
the Boala community forest produced 2,150.7 t/ha of biomass, which
corresponded to 1,075.35 t/ha of carbon, while the Rogho community forest
produced 402.81 t/ha of biomass, which corresponded to 201.41 t/ha of
carbon. The G1 group had the highest amount of carbon sequestered with
2,327.61 t/ha of biomass, which corresponded to 1,163.80 tC/ha. The CCEN
unit had the lowest amount with 262.49 t/ha of biomass, which corresponded
to 131.24 tC/ha. The proportion of herbaceous biomass in the carbon stock in
the Rogho and Boala sites was 4.49% and 0.8%, respectively. Therefore, there is a need to strengthen the management of these forest areas to further improve
their carbon storage potential.
