Document Summary
Review question: an important quality of ecosystems to consider when setting restoration goals is that: By 1591 it had dropped by about 97% (to 1. 2 million): native americans ran the continent as they saw fit. If we want to return the continent to its state in 1491, we will have to create the worlds largest gardens . Charles mann: historic ecosystems are important because they are useful analogs or guides to current restoration actions. Ecosystems are dynamic meaning they are ever-changing and influenced by the surrounding environment. The potential historical reference point may not be stable under current environmental conditions. The potential historical reference point may not even be possible in present day due to changing biota and environment. They help to define what the original or preferred condition was compared to the present. They help determine the factors that caused the degradation and define what needs to be done to restore the ecosystem.
