Epiphytic lichens growing on Oregon white oak in the Bald Hills, Redwood National Park
Denison WC and Sillett SC. 1990. Epiphytic lichens growing on Oregon white oak in the Bald Hills, Redwood National Park. Purchase order PX 8480-9-0479
In field work at Redwood National Park's Bald Hills (July-August 1989), the authors found 41 species of epiphytic lichens. These were living on Oregon white oak at 6 sites; the Schoolhouse Pasture Rock site received the most attention. Many of these lichen species have been documented elsewhere for air quality use, and species now growing in the Bald Hills indicate clean air to this point. Maintaining the oak woodlands may involve prescribed fire, but as fire temporarily devastates lichens, the authors recommend preserving the Schoolhouse Pasture Rock site as a source for lichen renewal, and for reference. Study purposes are preparation of an annotated checklist, collection of specimens, and comparison with Willamette Valley oaks. Illustrations include a map showing distribution of stands of 4 structural types; sketches of common lichens on Bald Hills oaks; tables of position, and of twig/branch/trunk data; and comparison data (Bald Hills and Oregon locations). The appendix is an annotated checklist of lichen species.
