The forester made an observation that the forest had mostly mature hemlock and very few young hemlock. This is common for outdoors scientists to make observations on the part of the natural world that is their field of study, and then draw conclusions from these observations.

Similarly, the paucity of young hemlock and the existence of mature hemlock could also spark a conclusion, such as maybe the mature hemlock were diseased so couldn't create new offspring or perhaps a fire had wiped out the young ones, as two possible explanations which would depend on the actual circumstances observed by the forester.
