اثربخشی مداخلات مدیریتی بر ذخایر کربن جنگل در جنگل های کاشته شده در نپال

We carried out case studies in four community forests planted between 1976 and 1990 to assess the impacts of management on forest carbon stocks. The study found that the average carbon stock in the pine plantations was 217 Mg C ha−1, and was lower in forests with intensively managed plantations (214.3 Mg C ha−1) than in traditionally managed plantations (219 Mg C ha−1). However, it was the reverse in case of soil carbon, which was higher (78.65 Mg C ha−1) in the forests with intensive management. Though stand density was positively correlated with carbon stock, the proportionate increment in carbon stock was lower with increasing stand density, as carbon stock increased by less than 25% with a doubling of stand density (300–600). The total carbon stock was higher in plantations aged between 25 and 30 years compared to those aged between 30 and 35 years.
