Who We Are
Oregon is a fantastic place to explore! Our state supports ten diverse ecoregions and more than 4,500 species of plants from the Blue Mountains to the Klamath Mountains.
We are the only organization that focuses on plants, one of the main building blocks of our natural environment. Since 1961 NPSO has been providing educational opportunities and advocating for Oregon’s native flora. Read one story about Botanical Education Workshops offered by NPSO for members and interested individuals, providing a broader variety of ways to learn about our native flora.
Thirteen local chapters are the heart of NPSO offering a variety of informational presentations, workshops, field trips, and opportunities to be involved with Oregon’s native plants and habitats.
We also provide enthusiastic support for the Oregon Flora Project, which is developing a new "flora" or taxonomical guide as well as providing an online atlas and photo gallery. The Flora of Oregon will be a one-volume manual of the vascular plants of Oregon, and will include identification keys, illustrations, and species descriptions.
One part of the NPSO mission statement is the enjoyment of Oregon’s native plants and habitats, and as such, field trips are a critical element. Our Chapters offer numerous field trips throughout the year to explore the biodiversity and natural wonders of Oregon. Socializing with people of like interests, learning and searching for little known plants, and appreciating our native habitats from the coastal headlands to the alpine meadows and old-growth forests to the high desert plateau are some of the mainstays of our organization.
Our newsletter, the Bulletin of the Native Plant Society of Oregon, is published 10 times per year providing organizational news, chapter meetings and events, articles on native plants, habitat and conservation, and reports from recipients of the NPSO field research grants. In addition, as part of our goal of collaborating with other environmental organizations and increasing educational opportunities for our members, NPSO advertises events from other non-profits in the Bulletin. An archive of the Bulletin is available on the NPSO web page.
Volume 20 of Kalmiopsis, the NPSO journal, contains in-depth articles on Oregon's native plants, stories of people who were and are part of our botanical heritage, book reviews, and more. All of Volume 20 and past issues are available via printed copies held by libraries or separate articles and sections in PDF format on our web site (http://www.npsoregon.org/publications.html).
We also publish occasional papers, a series that began in 1999. The most recent Urbanizing Flora of Portland, Oregon, 1806-2008 is a fascinating comparison between the pioneer flora of Portland and the present state.
Check www.NPSOregon.org for local chapter events such as wildflower shows, hikes, presentations, identification workshops, and weed-pulling parties. In addition, several chapters have community native plant gardens they care for and will gladly accept volunteer help.
NPSO's Oregon Native Plant Awareness Week is held during the first week of May. Oregon Native Plant Awareness Week is an opportunity for local NPSO chapters to reach out to the broader public raising awareness about the importance of native plants and habitats in Oregon. See http://www.npsoregon.org/ for details.
Every year NPSO members from around the state gather for an "Annual Meeting." The Mid-Columbia Chapter is hosting the 2015 Annual Meeting of the Native Plant Society of Oregon in Hood River, May 29 to 31. Hood River is located in the heart of the Columbia River Gorge, 65 miles east of Portland. Field trips will sample the flora on both sides of the Columbia River. It’s always fun to see old friends, meet new members, and explore another outstanding section of Oregon.
