The goal of reforesting degraded land is to create an area with a multitude of thriving tree species. But some experienced land managers use a reforesting strategy that involves planting a single fast-growing tree species. Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above?

C: Tree species that require abundant sunlight tend to grow quickly on degraded land.
D: The reforestation of degraded land is generally unsuccessful unless the land is planted with tree species that are native to the area designated for reforestation.
