Graduate student Lauren “Ivy” Clark has been knee deep in seeds ever since
she started her Master’s work at University of Washington. She first came to work with Rare Care in 2009 to develop protocols for propagating ten shrub-steppe species from seed for a project Rare Care was working on with BLM. Having developed an interest in germination ecology, Ivy also started working with Rare Care’s rare plant seed collection, conducting germination tests on collections held in the Miller Seed Vault. This ongoing work dovetails nicely with her thesis work, in which she explores the potential for hybridization between golden paintbrush (Castilleja levisecta) and harsh Indian paintbrush (C. hispida).
Both Castilleja species occur on Puget Sound prairies, and hybridization has been observed in a nursery setting. Recent golden paintbrush reintroductions have resulted in both species growing in close proximity to one another at out-planting sites. After ascertaining that the same pollinator species frequent both species, Ivy collected seeds from both species where they co-occur and is propagating them in the greenhouse. She will evaluate morphological features of the progeny to determine whether and to what extent hybridization is occurring at these reintroduction sites and whether the risk of hybridization is reduced by increasing the distance between neighboring individuals of the two species.
Ivy has had an interest in plants for as long as she can remember. Growing up in Texas, her interest in the natural world was nurtured by her parents. She’s held a variety of jobs since becoming a biologist, many of them restricting her to laboratories. Finding that she really enjoys being in the field, she hopes to use her skills and degree to work in the restoration ecology field. In the meantime, we are delighted to have her working on Rare Care projects and caring for our ex situ collection.

The latest issue of the Rare Plant Press is out. Learn about the rare Astragalus plant, projects to conduct a population estimate of the largest Sidalcea oregana var. calva and mapping Sisyrinchium sarmentosum populations, and more! The Rare Plant Press is a publication of Rare Care, a program dedicated to conserving Washington’s native rare plants.

Twenty-five volunteers, agency partners and Rare Care staff gathered in Klickitat County in mid-June to monitor known populations of rare plants in the Klickitat Wildlife Area, Conboy National Wildlife Refuge and surrounding areas. We knew from the outset that our survey plans had to be adjusted. Late wet spring conditions caused as much as a one-month delay in the onset of flowering for many species. We were too early to catch the long-bearded sego lily (Calochortus longebarbatus var. longebarbatus) in bloom. But we caught the tail end of Baker’s linanthus (Leptosiphon bolanderi), a tiny spring annual that normally blooms in April and May. Our timing was perfect for finding Pulsifer’s monkey-flower (Mimulus pulsiferae), another tiny annual found in seasonally moist areas that seemed to have benefited from the spring moisture.
Klickitat County was an ideal location for Rare Care’s fifth annual monitoring weekend. It’s at the east end of the Columbia River Gorge, a region that hosts some of the state’s most diverse flora. The Gorge is one of the few places in the northwest where moist Pacific air meets dry Columbia Basin air near sea level, providing a corridor for migration and a refuge for relict populations from previous glacial and interglacial periods. The Columbia River system also provides a significant corridor for species movement from its headwaters in the Rocky Mountain ecoregion of British Columbia, through the Okanogan highlands, Columbia Basin shrub-steppe, and east Cascades, and out to the wetter ecoregion of the west Cascades. The convergence of these topographic features is likely a major factor in the high number of endemic species found in the vicinity.
Twenty-four surveys were completed over the three-day campout, including new populations of rare plants such as oblong bluecurls (Trichostema oblongum), western ladies-tresses (Spiranthes porrifolia) and common bluecup (Githopsis specularioides). Regional endemics such as Barrett’s penstemon (Penstemon barrettiae), gooseberry-leaved alumroot (Heuchera grossulariifolia var. tenuifolia), and Suksdorf’s lomatium (Lomatium suksdorfii) are locally common on the cliffs and steep slopes of the Klickitat River. We monitored several populations of each and documented several new sites while surveying for other rare plant populations. We also monitored blue-flowered diffuse stickseed (Hackelia diffusa var. diffusa) and the very rare Ames’ milk-vetch (Astragalus pulsiferae var. suksdorfii), found in Washington only from an area around Conboy National Wildlife Refuge.
Although we accomplished so much in the short three days we had, we wrapped up the monitoring weekend with the impression that there is still much ground to cover in the region. We look forward to more explorations in the basalt canyons and pine woodlands in the coming years.
