The scale of forest and landscape restoration is expected to increase during the UN Decade on Ecosystem Restoration and its contribution to the provision of critical ecosystem services to *** models of forest restoration may improve ecosystem services,including soil organic carbon(SOC)storage.A review was carried out to access:(1)the variability of SOC storage between worldwide forest restoration models and,(2)the effects of climate,soil class,soil texture,and vegetation type on SOC *** reviewed 119 primary studies with information on SOC and soil texture for different forest restoration *** restoration models were grouped into four categories:natural regeneration,monocultures,agroforestry,and mixed *** data was extracted from these four restoration models,other land uses(cropland,bare land,grassland,and natural forest),climate regimes,and soil *** SOC storage in the forest restoration models and other land uses at a global scale ranged between 0.1 to 514 Mg ha^(-1).The overall mean value for SOC storage was higher for natural regeneration(112 Mg ha^(-1)),followed by agroforestry(74 Mg ha^(-1)),mixed forest(73 Mg ha^(-1)),and monocultures(68 Mg ha^(-1)).However,the average SOC storage was similar among the four restoration models in the moist warm climate *** SOC storage mean value in the moist cool zone was 23%higher than the dry cool zone(81 and 62 Mg ha^(-1),respectively),and 50%higher for the moist warm zone when compared to the dry warm climatic zone(74 and 38 Mg ha^(-1),respectively).The SOC storage of the restoration models was positively related to soil depth(0.59;p<0.01),clay content(0.29;p<0.01),and stand age(0.17;p<0.01).Globally,the mean values of SOC storage were 26,66,and 139 Mg ha^(-1) at zero-10,zero-30,and zero-100 cm depths,*** addition,sandy soils showed smaller mean values of SOC storage than medium to clay soils,especially in deeper soil ***,SOC storage was positively re
