1. Explain why retention of a partial canopy of trees (e.g., mother trees) during timberharvesting rather than clearcutting, and planting the area with a mixture of species ratherthan a monoculture, may reduce the time for above and below ground carbon storage (netecosystem production) to recover.
2.Explain why and how fire severity can vary across a temperate forest landscape, and how and why this could affect forest successional patterns.
3.Explain the hydrologic cycle in a watershed and what effect an impermeable surface has on groundwater.

Very good critical thinking and/or analysis skills are evident. All parts of the question are answered. In addition, the argument contains originality and demonstrates an understanding of ecological mechanisms. Excellent (80-89) An excellent understanding of the relevant issue is demonstrated. Very good critical thinking and/or analysis skills are evident. All parts of the question are answered. Good (68-79) A good understanding of the relevant issue is demonstrated. Some critical thinking and/or analysis skills are evident. One of the parts of the question remains unanswered. Fair (55-67) A marginal understanding of the relevant issue is demonstrated. Evidence of critical thinking and/or analysis skills is minimal. More than one part of the question remains unanswered.
