Klamath Basin Chapter, 
Native Plant Society of Oregon

Dedicated to the enjoyment, conservation & study of the Basin's native flora. 

The Upper Klamath Basin is located in Southern Oregon and Northern California. It covers an area of more than 7200 square miles and is bordered by the Cascade Mountains on the west and the Gearhart Mountain area on the east. The basin extends north to Chemult and south below the Oregon/California border.

The habitats range from high desert to marshes and sub-alpine meadows to alkaline flats. The diversity is amazing with more than 1000 plant species documented.

The Klamath Basin Chapter of the Native Plant Society of Oregon (NPSO) was formed to promote awareness of the native flora in our region. The KBNPS meets regularly to educate its members and the public about conserving, propagating, and identifying our plants and flowers. We organize field trips to hike through the forest to see rare wildflowers in bloom, wade through marshes with expert guides to see sedges and carnivorous plants and walk the trails in local parks to explore the diversity of the plant life.

If you have ever sat in a meadow and wondered what that pretty pink flower was or driven through the woods and wondered how many different trees you saw, then becoming a member of the Klamath Basin Chapter of the Native Plant Society might be for you.
