By 10,300 years ago, the coastal and lowland areas of Prince of Wales Island had developed forest cover, but the specific composition of that forest differed from the mature old-growth forest of today.

The early post-glacial forest on the island was likely dominated by species that colonize newly available land quickly — shore pine, red alder — rather than the slower-growing but ultimately dominant Sitka spruce and western hemlock.

The transition from early successional forest to climax forest is a process that takes centuries to millennia, and at 10,300 years, the forest of Prince of Wales Island was still in intermediate stages of this succession in many areas.

The implications for the human ecology of the period are specific.
