Alnus rubra
The islands were heavily logged in the nineteenth century, but now have an extensive second-growth coast Douglas fir ("Pseudotsuga menziesii var. menziesii"), Pacific madrone ("Arbutus menziesii"), red alder ("Alnus rubra") and bigleaf maple ("Acer macrophyllum") forest. There are small stands of old-growth Douglas fir and western redcedar ("Thuja plicata"), mostly within long standing privately held property. In the highlands one also finds grand fir ("Abies grandis"), western hemlock ("Tsuga heterophylla") and other subalpine trees.
