“…The average forest C storage was lower than that of Quercus spp. (90.44 Mg·ha −1 ) in South Korea by Nam et al [47], but larger than in the study by Boulmane et al [48] in forest stands of Tafachna (53.7 Mg·ha −1 ) and Reggada (48.3 Mg·ha −1 ) in the Central Middle Atlas. The carbon storage in plant components increased at first, achieving maximum storage in near-mature stands (100.40 Mg·ha −1 ) and then decreased in mature stands (61.45 Mg·ha −1 ).…”

Large-scale Quercus variabilis natural secondary forests are protected under the Natural Forest Protection (NFP) program in China to improve the ecological environment. However, information about nutrient characteristics and carbon (C) storage is still lacking. Plant biomass and C, nitrogen (N) and phosphorus (P) stoichiometry of tree tissues, shrubs, herbs, litter, and soil were determined in young, middle-aged, near-mature and mature Quercus variabilis secondary forests in the Qinling Mountains, China. Tree leaf N and P concentrations indicated that the N-restricted situation worsened with forest age. The per hectare biomass of trees in decreasing order was near-mature, mature, middle-aged, then young stands. The majority of the biomass was in the stems (44.88-48.15%), followed by roots (24.54-28.68%), and branches (10.15-14.16%), and leaves made up the lowest proportion (2.86-3.55%) of trees. C storage at plant layer increased significantly with age, reaching maximum values in near-mature stand (100.4 Mg·ha −1 ) and then decreasing in mature stands. Soil C storage at a depth of 0 to 100 cm was 82.8, 96.8, 85.8, 104.2 Mg·ha −1 , and C storage of forest ecosystem was 122.8, 163.0, 184.9, 178.3 Mg·ha −1 in young, middle-aged, near-mature, mature stands, respectively. There were significant correlations between biomass and C, N, P stoichiometry in different layers, especially in young stands.

“…This variation depends on the nature of the soil in the study area. The carbon stocks found in this layer under the green oak stands are higher than those observed by Boulmane (2010), which are of the order of 63 t/ha and 47 t/ha respectively in the forests of Tafechna and Reggada considered relatively degraded. This SCOS value is still higher than that recorded under cork oak stands in the Maamora forest (78 t/ha) (Oubrahim 2015) and in the Moroccan Rif (100 t/ha) (Sabir et al, 2002).…”

Soil organic carbon sequestration is an important matter in international negotiations to fight climate change through a reduction in greenhouse gas (GHG) emissions. This study was carried out in the forests of the Moroccan Central Middle Atlas, with the objective of determining the storage of carbon in the high organo-mineral layer of soils (<30 cm deep) and under different spontaneous forest species in this area. It shows that the soil organic carbon stock (SOCS) in these forest ecosystems is higher in green oak and deciduous zeen oak forest stands, recording 264.73 and 251.54 t/ ha respectively on a basaltic substrate followed by cedar (resinous species) (178.07 t/ha). Mixed forest stands come at last with low SOCS (109.02 t/ha). This variation may be attributed to several factors, mainly the type of vegetation, the physical and chemical soil properties and soil type of the studied area.

“…Pour estimer la biomasse aérienne et racinaire présente dans chaque arbre, les équations suivantes ont été utilisées. Equation 2: BA = (D en cm) Equation 3: BR = La détermination de la quantité de carbone présente dans les différentes composantes de l'arbre et dans chaque plantation a été faite en se basant sur les équations allométriques de la FAO (1997) et adapté (Tableau 1) selon les modèles du stock de carbone pour les différentes composantes des arbres par Boulmane et al (2013).…”

“…Le stock de carbone est significativement plus élevé dans la biomasse aérienne que dans la biomasse racinaire. Ce résultat corrobore celui de Boulmane et al (2013) ; de Bello et al (2017) et Diatta et al (2016) qui ont obtenu des résultats similaires au Maroc dans la chênaie verte, au Bénin sur plantation d'anacardier et au Sénégal dans le Sud du Bassin Arachidier. Montagnini et Nair (2004), ont montré que les efforts de captation de carbone en milieu tropical sont concentrés sur la biomasse aérienne et non sur les sols.…”

La réduction du dioxyde de carbone par les arbres est une importante activité écosystémique. La présente étude vise à déterminer le stock de carbone organique dans les plantations de Acacia auriculiformis des forêts classées (Ouèdo et Pahou) afin d'appréhender leur contribution à l'atténuation des changements climatiques. La méthodologie d'estimation du carbone est basée sur les recommandations faites par l'IPCC et celle de FAO ainsi que des équations allométriques. Les données climatiques ont été collectées à la station météorologique d'Agonkanmè. Selon les différents compartiments, les résultats révèlent que le stock de carbone est plus élevé dans le tronc : 78,17%; les branches : 19,50% et les feuilles: 2,33%. Le potentiel de séquestration du carbone du sol varie entre 31,46% et 70,99% en fonction des types de sol. Les stocks de carbone élevés sont obtenus dans la plantation de 2,5 ans sur sol hydromorphe à Pahou (106,23 ± 38,39 tC/ha) contre 77,77 ± 5,47 tC/ha pour celle de 2 ans sur sol ferralitique à Ouèdo. Il y a une corrélation fortement négative et significative (r =-0,931, P < 0,001) entre la température et le stock de carbone. Les fortes températures observées sont le résultat de la faible séquestration de carbone et vice-versa.
