Three complementary approaches to the conservation and
maintenance of old-growth forests and old-growthness have been
termed reservation, retention, and restoration (Beese et al., 2003;
Franklin et al., 1997; Keeton, 2006; Seymour and Hunter, 1999).
The reservation of large patches of old-growth forests is an
important element of an effective multi-scaled approach to the
conservation of biodiversity at the landscape scale (Lindenmayer
and Franklin, 2002)
