Quantification du stockage de carbone des écosystèmes et de la diversité floristique dans la forêt urbaine El Maabouda

Abstract

The present work consists of analyzing the health status and structure of the El Maabouda urban woodland, which is part of one of the Mediterranean ecosystems of northeastern Algeria (Setif), characterized by the dominance of Pinus halepensis Mill. and Cupressus sempervirens L. The adopted methodology consists of collecting field information through the establishment of six randomly selected plots with an area of 400 m² during the period of April and May 2026. Dendrometric measurements of trees, particularly circumference, height, diameter, and crown characteristics, were taken, as well as the health status of these trees (leaves, branches, and stem) was analyzed. Carbon storage was estimated based on tree biometric parameters and appropriate evaluation methods. The obtained results show that tree density varies from one station to another, and stress manifestations such as leaf discoloration and reduction in foliage density were recorded. It appears that stations with denser vegetation cover and more stable forest structures show higher carbon sequestration rates. This study highlights the importance of the conservation and sustainable management of urban forest areas to strengthen their contribution to carbon sequestration and biodiversity maintenance
