, or eastern white-cedar (Thuja occidentalis L.). Rare SFUs also included eastern white pine (Pious strobus L.) and (or) red pine (Pious resinosa Ait.) leading stands managed by shelterwood or seed tree silviculture as well as low-lying deciduous stands and selection-managed stands of ...
Carr.) and northern white cedar ( Thuja occidentalis L.). The pattern of change in basal area growth varied among species, ranging from a steady increase to a more or less rapid decline. There was a good agreement between observations and predictions for yellow birch, red spruce, red maple...
Stand volumes were determined for naturally established, even-aged, single- and mixed-species stands involving three combinations of shade-tolerant and shade-intolerant conifers on similar sites: (i) western redcedar western hemlock (Thuja plicata Donn ex D. Don - Tsuga heterophylla (Raf.) Sarg...
In northern lower Michigan, logging accelerated sugar maple (Acer saccharum) dominance in a northern white cedar (Thuja occidentalis) community, and clear-cutting and burning quickly converted certain sites dominated by mature jack pine (Pinus banksiana) to early-successional hardwoods, including Prunus...
