It was based on two visits to what was then The Nature Conservancy's Northern California Coast Range Preserve. During the 1970's, a second list was prepared by G. Lester. This second list was based on a number of visits over a two year period, and documented the presence of many species not on the initial list. Over the past five years, as part of an on-going project to describe the Reserve's flora and vegetation, I have been revising these earlier lists and adding additional information.

The habitat of each species is described in terms of one or more general vegetation types (occasionally with additional notes). Most of the Reserve is covered by "mixed evergreen" forests. Primarily these fall into two categories: Pseudotsuga-Lithocarpus forests (mainly north-facing slopes) and Pseudotsuga-mixed hardwood forests (most aspects other than north-facing). In Pseudotsuga-Lithocarpus forests, the canopy is dominated by Pseudotsuga menziesii and Lithocarpus densiflorus together with Arbutus menziesii. The canopies of Pseudotsuga-mixed hardwood forests vary in the abundance of Pseudotsuga and their other dominants include Arbutus, Quercus chrysolepis, Quercus wislizenii and Umbellularia californica.

Within this general matrix of mixed evergreen forest, there are inclusions of other vegetation types. Along stream courses there is riparian vegetation on banks and in the active channel, particularly on gravel bars. Outside of the riparian zone but in adjacent mesic locations (valley bottoms and the lower portions of slopes) there are a number of plants more characteristic of coastal forests, and there are stands of nearly pure Pseudotsuga menziesii and even some patches of Sequoia sempervirens. On uplifted alluvial terraces and some ridgetops, there are meadows and patches dominated by deciduous oaks. The meadows are strikingly varied in their composition and structure. (Native perennial grasses are usually among the dominants.) The oak patches are of Quercus garryana at lower elevations and Q. Kelloggii at higher. Though these oak patches vary from open canopied woodlands to forest stands, I call them woodlands on the species list. On south-facing slopes and along some ridgelines, there also are patches of chaparral. Adenostoma fasciculatum, Arctostaphylos glandulosa and Quercus wislizenii are particularly abundant within these chaparral patches.

Within these habitats, species abundance is described as frequent, infrequent or rare. Frequent species are common within the specified habitat. They are found over a large portion of the habitat's acreage. Infrequent species are within only a small percentage of a habitat's area, and rare species are known from only one to several restricted localities.},

This checklist is an extension of two previous lists. The first list was produced by G. Ledyard Stebbins in 1968. It was based on two visits to what was then The Nature Conservancy’s Northern California Coast Range Preserve. During the 1970’s, a second list was prepared by G. Lester.
