Plant Communities
In northern regions where coniferous forests nest sites are unavailable, marbled murrelets occupy alpine or tundra near the ocean. In Washington and Oregon, marbled murrelets commonly nest in Douglas-fir (Pseudotsuga menziesii) dominated stands. They also select stands dominated by mountain hemlock (Tsuga mertensiana), western redcedar (Thuja plicata), and Sitka spruce (Picea sitchensis) for nesting. In California, nests are most often located in redwood (Sequoia sempervirens) dominated stands with scattered Sitka spruce, western hemlock (Tsuga heterophylla) and Douglas-fir. Marbled murrelets also occur in stands dominated by Port-Orford-cedar (Chamaecyparis lawsoniana).

Famous quotes containing the words plant and/or communities:
“The student of Nature wonders the more and is astonished the less, the more conversant he becomes with her operations; but of all the perennial miracles she offers to his inspection, perhaps the most worthy of admiration is the development of a plant or of an animal from its embryo.”
—Thomas Henry Huxley (182595)
“I am convinced, that if all men were to live as simply as I then did, thieving and robbery would be unknown. These take place only in communities where some have got more than is sufficient while others have not enough.”
—Henry David Thoreau (18171862)
