I suggest that you may be a little preoccupied with mycorrhizal fungi. I
don't question their ecological importance, and I don't question their
neglect by the F.S. and the ecological research community. But to suggest
that the spotted owl was chosen as an indicator species because it
disperses fungal spores strains credulity. It was chosen because it was
thought to be an old-growth specialist. The endangered species act can be
used to protect animals. It cannot be used to protect seral stages.
Your post illustrates how dificult it is to work with biologists. They
tend to be so focused on their taxa of choice that they lose perspective on
the overall forest community, not to mention the full range of management
