Growth rates were adjusted based on tree canopy condition. Adjustment factors were proportional to percent crown dieback (i.e., the greater the crown dieback, the slower the growth rate) and the assumption that less than 25% crown dieback had a limited effect on dbh growth rates. For trees with fair to excellent condition (less than 25% dieback), no adjustment was made to the growth rate; for poor condition trees (26% to 50% dieback), growth rates were multiplied by 0.76; critical trees (51% to 75% dieback) by 0.42; dying trees (76% to 99% dieback) by 0.15; and dead trees by 0. The difference in estimates of carbon storage between year x and year x+1 is the net amount of carbon sequestered annually.
