John Weeks discusses the richness of virgin lands and forests. In the turn of a century the removal of forests have reached the point where the lands no longer supported the pigeons.

The land was once in a virgin condition and has permanently lost important species of food producing trees. But the land is resilient and can rebuild it's rich potential if allowed to.
