... suspiciously young old- growth forests are 6 0- to 120 -year -old oak stands (Laiolo et al. 20 03), a 100-year -old boreal Norway spruce stand (Dahlberg et al. 1997), and a 110-year -old Balsam fir stand (Sturtevant ... Boreal old- growth forests were somewhat younger (median age 22 4 years, inter-quartile range 150 300 years), whereas tropical old- growth forests tended b...
