Question
Does the destruction of large trees in a windstorm change forests in any important way? Here is the conclusion of a study that found that the answer is no:
We found surprisingly little divergence between treefall areas and adjacent control areas in the richness of woody plants (P=0.62), in total stem densities (P=0.98), or in population size or structure for any individual shrub or tree species.
The two P-values refer to null hypothesis that “no difference” in measurements between treefall and control areas. Explain clearly why these values provide no evidence of a difference.
