“…Studies on C storage and sequestration by urban forests have been mostly conducted in the United States (Rowntree and Nowak, 1991;Nowak, 1993Nowak, , 1994Jo and McPherson, 1995;McPherson et al, 1997McPherson et al, , 1999McPherson, 1998;Myeong et al, 2006;McHale et al, 2007McHale et al, , 2009Escobedo et al, 2010). However, there has been an increasing interest in quantification of C storage and sequestration by urban forests in both developing and developed countries (e.g., Brack, 2002;Jo, 2002;Yang et al, 2005;Gratani and Varone, 2006;Myeong et al, 2006;Stoffberg et al, 2010;Zhao et al, 2010). These studies greatly expand our understanding on the role of urban forests in C storage and sequestration.…”
