- Abstract:
- In the autumn of 1924 the Harvard Forest marked for cutting a lot owned by the New England Box Company which contained a stand unusual in northern Massachusetts. It was composed of dense, almost pure, white pine and hemlock with very little ground cover or advance growth hardwood. The composition ranged from pure hemlock to nearly pure pine. But of special interest was the fact that the entire area was thickly sprinkled with old pine stumps which clearly testified that years before a heavy softwood cut had been made on the same area. Now as a general rule the forests which have followed nineteenth century softwood logging operations have resulted both in a conversion and a marked deterioration of type. But here softwood had followed softwood, and furthermore the new stand had both a large volume and excellent form. What was the history which had caused this anomaly? It was in answer to this question that the present study was undertaken.
