Red bilberry (Vaccinium parvifolium Sm.). A variety of herbs, many restricted to the red-wood type, are found on the redwood forest floor. They include (Jepson ; Person ): Deerfoot vanillaleaf (Achlys triphylla [Sm.] DC.) Western baneberry (Actaea spicata L.

var. arguta Torr.) Glade anemone (Anemone deltoidea Hook.). Both Smith’s and Hooker’s fairy bells enjoy the company of others in the Western hemlock/Douglas-fir or coastal redwood plant community, including red alder, vine maple, Indian plum, evergreen huckleberry, inside-out flower, oxalis, alumroot, trillium, sword fern, deer fern, salal, vanilla leaf, piggyback plant, foam flower, and many others.

A study of three sources of inland Douglas-fir has shown that quantitative differences in monoterpene composition of oleoresin are present and that these differences are associated with attack by Douglas-fir beetle.

Related work with western white pine has shown that monoterpene concentrations are independent of climate and site characteristics. The Western blood-red ladybird beetle (Cycloneda polita) — one of about 90 species throughout the Pacific Northwest and about 6, species worldwide — is tiny (4 to 5 mm), but like most others in the Coccinellidae family, is a voracious consumer of aphids, scale insects, and mites; a few species eat fungi.

The major forest complex consists of Douglas-fir (Pseudotsuga menziesii) and Western hemlock (Tsuga heterophylla), encompassing seral forests dominated by Douglas-fir and massive old-growth forests of Douglas-fir, Western hemlock, Western red.

This report was developed from discussions on the role of Ceanothus in western forests that took place at a workshop held November, at Oregon State University, Corvallis, Oregon. Full text of "Madroño: a West American journal of botany" See other formats.

In western Oregon, Chen () found that plant abundance and diversity decreased after herbicide treatment, but vegetation recovered at varying rates due to a number of factors (i.e., native or exotic species, site characteristics) once treatments ceased.
