Forester: The great majority of the forests remaining in the world are only sickly fragments of the fully functioning ecosystems they once were  These fragmented forest ecosystems have typically lost their ability to sustain themselves in the long term, yet they include the last refuges for some of the world' s most endangered species
To maintain its full complement of plant and animal species, a fragmented forest requires regular interventions by resource managers
Most of the world's forests will lose at least some of their plant or animal species if no one intervenes.
