One weekend, two dozen rare plant surveys

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.

BioBlitz reveals potentially rare stinging ant, mushroom, spider & possible new plant invaders

May 29th, 2010 by Jennifer Youngman, Communications Specialist

With more than 100 citizen scientists, university students and professionals scrutinizing Washington Park Arboretum’s nooks and crannies during Seattle’s first BioBlitz, there were bound to be a few surprises. A potentially rare native stinging ant, a potentially rare Amanita (mushroom) not often seen on the west coast, a potentially new species of spider and a couple of unexpected plants displaying suspicious behavior are just a few of the discoveries. Plus, a spider that is regionally rare appears to be common on Foster Island.

The inventory of the Arboretum’s birds, bats, lichens, fungi, reptiles, amphibians and plants (not counting the Arboretum’s plant collection, which is already documented) started at 3:00 PM May 21 and lasted 24 hours, including night-time shifts for cataloguing nocturnal life. One nocturnal lesson: participants collected regurgitated barred owl pellets, dissolved all of the material but bones, and identified bones and skulls to determine that the Arboretum’s owls dine primarily on Norway rats.

BioBlitz plants & animals mapped using handheld devicesThe après-BioBlitz is now in session. Data is being processed. Plant and invertebrate identification continues. Rare species are being confirmed. And plants such as Lonicera periclymenum, an ornamental Eurasian vine not known to be invasive here but found scrambling over plants, will be investigated to see whether they are potential new invaders in this region.

BioBlitzes have served as vehicles for biodiversity data collection for several years in locations ranging from the Nisqually Delta to Cape Cod and New York City’s Central Park. Seattle’s BioBlitz will be useful in establishing baseline data before the Highway 520 bridge project gets underway. Dr. Sarah Reichard, professor and co-associate director of the UW Botanic Gardens, worked with the Washington NatureMapping Program to organize this major undertaking, and the Arboretum Foundation funded it. Although insects were underrepresented due to cold weather and no bats were netted, more than 400 species of plants, animals, lichens and fungi were recorded. View the species tally to date and a list of predicted vs. observed birds, amphibians, reptiles and mammals.
