Note that the OGMAs are mostly small and isolated. As well, in the low elevation subzones, most of the OGMAs are not old growth at all as there isn’t enough left to meet the LU Plan retention target of 8%.

Forest inventory combined with ecosystem classification shows us that:

It is physically impossible to protect the natural diversity of plant communities and ecological processes on such a small land base as that currently provided by the LU Plans and Provincial Parks of our Natural Resource Districts.
