From the 2016 report for the 2010 'project';

No. of trees declined from 115244 on June 30 2015 to 110790 on June 30 2016. Assuming the difference is down to mortality that's 3.9% drop in one year. More consistent with 40% survival rate over 15yrs than 85%

perhaps the more recent plantings will indeed have 85% survival rate when they get to maturity, but in the meantime the ones that are going to be harvested sooner look like having higher mortality rates.

data sample of one, admittedly
