There is an estimated 797,000 board feet of Douglas fir; 339,000 board feet of western hemlock; 105,000 board feet of white fir; 21,000 board feet of Port Orford cedar; 213,000 board feet of red alder; and an undetermined volume of tanoak and other hardwoods.
The vegetation was second growth mixed conifer consisting of redwood (Sequoia sempervirens), Douglas-fir (Pseudotsuga menziesii), and tanoak (Notholithocarpus densiflorus).
and the related tanoak (Notholithocarpus densiflorus), but it spreads by spores formed on foliar lesions on scores of other plant species, including common landscape plants (Rizzo and Garbelotto 2003).
The forest here is mixed hardwood and conifer and includes such species as Douglas-fir, tanoak and madrone.
A mix of dominant tree species including redwood (Sequoia sempervirens), Douglas fir (Pseudotsuga menziesii), grand fir (Abies grandis), western hemlock (Tsuga heterophylla), and Sitka spruce (Picea sitchensis), and, to a lesser extent, western red cedar (Thuja plicata), with associated species including tanoak (Lithocarpus densiflora), red alder (Alnus rubra), big leaf maple (Acer macrophyllum), and vine maple (Acer circinatum).
Genetic diversity, structure, and demographic change in tanoak, Lithocarpus densiflorus (Fagaceae), the most susceptible host to the Sudden Oak Death disease in California.
Then take the trail's right-hand fork half a mile through tanoak woods to a road.
The disease, which has reached epidemic proportions in California is causing widespread death of Oak and Tanoak Trees and is commonly known there as "Sudden Oak Death".
In our dataset, obvious habitat differences would not account for differences in disease exposure, given the presence of live oak, tanoak, redwood, and Douglas fir at many sites.
The principal host for the fungus in North America is tanoak (Lithocarpus), not a true oak at all but one whose bark is widely used in the tanning industry.
