“…The elevation of the forest area ranges between 180 and 800 m above sea level (a.s.l.). 21 According to data of the Gharakheill Meteorological Station, the mean annual precipitation and temperature were 733 mm and 16.8 C, respectively. The climate is temperate moist and the dry months extend from May to September.…”

“…is also present. 21 However, some parcels were not afforested in 1991 and are now covered by sparse herbaceous species including Asperula odorata L., Euphorbia amygdaloides L., Hypericum androsaemum L., and Polystichum sp. Since 2006, this forest represents an Experimental Forest Station of the Mazandaran University.…”

“…Besides C cycling, soil quality, and land management, afforestation is an important land use change affecting also regional socioeconomic development. 42 Taking into account the whole 0-40 cm profile, and the afforested areas of red pine (5.5 ha), oak (7 ha) and maple (7 ha) stands in the Darab Kola region, 21 it is possible to estimate the influence of each stand in terms of SOCS, that is about 898.0, 844.5, and 714.8 Mg C, respectively.…”

Following the ratification of the Kyoto Protocol, afforestation of formerly arable lands and/or degraded areas has been acknowledged as a land-use change contributing to the mitigation of increasing atmospheric CO(2) concentration in the atmosphere. In the present work, we study the soil organic carbon sequestration (SOCS) in 21 year old stands of maple (Acer velutinum Bioss.), oak (Quercus castaneifolia C.A. Mey.), and red pine (Pinus brutia Ten.) in the Darab Kola region, north of Iran. Soil samples were collected at four different depths (0-10, 10-20, 20-30, and 30-40 cm), and characterized with respect to bulk density, water content, electrical conductivity, pH, texture, lime content, total organic C, total N, and earthworm density and biomass. Data showed that afforested stands significantly affected soil characteristics, also raising SOCS phenomena, with values of 163.3, 120.6, and 102.1 Mg C ha(-1) for red pine, oak and maple stands, respectively, vs. 83.0 Mg C ha(-1) for the control region. Even if the dynamics of organic matter (OM) in soil is very complex and affected by several pedo-climatic factors, a stepwise regression method indicates that SOCS values in the studied area could be predicted using the following parameters, i.e., sand, clay, lime, and total N contents, and C/N ratio. In particular, although the chemical and physical stabilization capacity of organic C by soil is believed to be mainly governed by clay content, regression analysis showed a positive correlation between SOCS and sand (R = 0.86(**)), whereas a negative correlation with clay (R = -0.77(**)) was observed, thus suggesting that most of this organic C occurs as particulate OM instead of mineral-associated OM. Although the proposed models do not take into account possible changes due to natural and anthropogenic processes, they represent a simple way that could be used to evaluate and/or monitor the potential of each forest plantation in immobilizing organic C in soil (thus reducing atmospheric C concentration), as well as to select more appropriate species during forestation plan management at least in the north of Iran.
