Saddle Mountain (1000 m) is the highest peak in the Northern Oregon Coast Range. Meadows are found to occur at and near the summit of the mountain which contain abundant wildflowers. Although the majority of these meadow species have been collected and identified in the past no formal study has been done to classify them into communities. The purpose of this study is to examine the character and origin of the plant communities located at or near the summit of Saddle Mountain. Data were collected on 4 study sites during the Summer of 1996 and analysis of the data lead to the identification of 2 plant communities in these meadow areas. They are the Leondoton autumnails Association and the Achillea millefolium Association. The Leontodon autumnalis Association was found to inhabit those sites with the most poorly developed soils. The Achillea millefolium Association was found to inhabit those sites where better developed soils were found. Saddle Mountain is the home of 301 plant species. Of these, approximately 40 are relict species that became established on Saddle Mountain during periods of climatic extremes and have their centers of origin in higher and distant mountains such as the Cascade and Olympic mountains.
