Rare Care is fortunate to partner with several land trusts in the state to conserve rare plants. One such organization is the Columbia Land Trust, who works across five ecosystems from the mouth of the Columbia River to approximately 200 miles inland and 50 miles north and south of the river in Washington and Oregon. We reached out to Nate Ulrich, Conservation Manager, to find out more about their work.

Common name: Japanese Ornamental Cherry
Family: Rosaceae
Native Range: Japan
In the Arboretum: Along Azalea Way
Issues: brown rot, cherry bark tortrix larvae, crown gall, root rot, low tolerance of compacted or wet soils

During spring’s first blossoms, I brag to anyone who will listen that the Japanese ornamental cherries at the Washington Park Arboretum are the most amazing display in the city and that they MUST go for a walk along Azalea Way to view this splendor. 

“The Arboretum is over 230 acres and it is absolutely a public space. And when we say public that means everyone, not just the people that live close by,” says Christina Owen, co-director of UWBG.

This excruciatingly rare plant has been documented in only one place: along a basalt ridgetop at the Hanford Reach National Monument.

Allie Howell transitioned into Rare Care’s temporary Research Scientist position in February. Through September, she will be collecting field data, growing plants for outplantings, and helping with reporting on our many on-going research projects.
I have the exciting opportunity to delve deeply into several of this program’s ongoing projects.
So far, most of my work has been devoted to conducting vulnerability assessments on the rare alpine plants I monitored in the North Cascades, Olympic and Mt.

Lake Chelan is a narrow, glacially-carved trench: 50 miles long from North Cascades National Park to the town of Chelan. Along its shores, species typical of both the east and west flanks of the Cascades Range are well-represented. The areas surrounding the lake also contain a number of rare plant species, including some that occur nowhere else in Washington. 

This summer as Rare Care Interns we worked on an alpine plant monitoring project for the National Park Service. On the surface, our job was simple: go to a site in Olympic, North Cascades, or Mt. Rainier National Parks, find the plant, map the edges of the population in the area, and usually set up a permanent plot to be monitored by the National Park Service in the future.

Over the past five months I have been immensely privileged to work on several of Rare Care’s projects restoring our beloved native rare plants all over Washington state. From hot July afternoons helping map shimmering meadows of pink Wenatchee Mountains checkermallow (Sidalcea oregana var calva) and purple Wenatchee larkspur (Delphinium viridenscens), to epic early mornings counting baby seedlings of White Bluffs bladderpod (Physaria douglasii ssp.

It is hard to believe that summer is over, and Allie and I have gone on 7 backpacking trips and 2 camping trips. Each of them very unique and special. From beautiful forest walks to steep crumbling slopes. We have covered so much ground and been to places I never thought I could reach. Working for Rare Care this year has been a privilege and a challenge. 

“This trial is significant as it really does put data to the observations–not just qualitatively, but quantitatively–about how plants are performing,” says Ray Larson, Curator of Living Collections at UWBG.
