and a relatively poor quality site (SI,, = 13 m) may
provide CWD at 78 years and will be ready for
harvest at 108 years, creating a 17-year and 30-year
habitat window, respectively. These figures assume
that trees on good, medium, and poor quality sites
reach breast height at 6, 7 and 8 years, respectively
(Page and Van Nostrand, 1973).
