Abstract
This study aimed to assess forest carbon stock and associated emission factors of the Subtropical and Temperate forests of District Lower Dir of Khyber Pakhtunkhwa Province, Pakistan. Stratified Cluster Sampling with a nested plot approach was applied to carry out the study. 36563 ha of the study area was found under forest cover encompassing three main forest types i.e. Moist Temperate Forests 18163 ha (50%), Subtropical (ST) Chir Pine Forests 17382 ha (47%), and ST Broad-Leaved Evergreen Forests 1018 ha (3%). The study estimated total carbon stock of 818019 MgC in the forests of Lower Dir with the highest contribution of 427078 MgC (52%) by Moist Temperate Forests, followed by 381297 MgC (47%) of ST Chir Pine Forests and 9644 MgC (1%) of ST Broad Leaved Evergreen Forests. The highest mean carbon density of 23.51 MgC ha-1 was found in Moist Temperate Forests, followed by 21.94 MgC ha-1 of ST Chir Pine Forests and 9.47 MgC ha-1 of ST Broad Leaved Evergreen Forests. The study infers that emission of 83 MgCO2-e ha-1 from Moist Temperate Forest, 78.31 MgCO2-e ha-1 from ST Chir Pine Forests, and 34.45 MgCO2-e ha-1 from ST Broad Leaved Evergreen Forests would occur if deforestation occurs in the area.
