Developing population density estimates for nine rare Willamette Valley prairie species Prepared by Rebecca Currin, Melissa Carr, and Robert Meinke OREGON DEPARTMENT OF AGRICULTURE for U.S. Fish and Wildlife Service NATIVE PLANT CONSERVATION PROGRAM (Grant No. OR-EP-2, Seg. 17) March 31, 2008 Citation Currin, R., M. Carr and R. Meinke. 2008. Developing population density estimates for nine rare Willamette Valley prairie species. Report prepared for U.S. Fish and Wildlife Service, Region 1, Portland, Oregon. Oregon Department of Agriculture, Salem, Oregon. Acknowledgements As one might imagine, many people contributed to the successful completion of this project. The authors wish to thank the U.S. Fish and Wildlife Service for funding our efforts to increase the body of knowledge available for Oregon’s rare prairie species. Over the course of the last two and a half years, we were lucky to work with many wonderful land owners and managers. In particular, we would like to thank the following people for allowing us access to their little pieces of prairie (and sometimes even going out and collecting data with us!): Tom Franklin and Patricia Farrell (City of Salem); Steve Gisler and Nick Testa (Oregon Department of Transportation); Sally Villagas (Bureau of Land Management, Eugene); Susan Carter (Bureau of Land Management, Roseburg); Kurt Heckeroth (Bureau of Land Management, Salem); Carl Borg (City of Hillsboro); Jason Nuckols, Jason Dumont, Greg Fitzpatrick, and Gil Voss (The Nature Conservancy); Chris Seal and Jock Beall (U.S. Fish and Wildlife Service); Dennis Wiley (Oregon Parks and Recreation Department); David Lebo (U.S. Forest Service, Mt. Hood National Forest); Angie Kempo and Curt Zonick (Metro); Steve DeGhetto (Corvallis Parks and Recreation); Brian Carroll (Linn County Parks and Recreation); Irene Pilgram and Debbie Johnson (Oregon State University); Jeff Mach and Terry Larson (Oregon Military Department); Mike Moore (Oregon Department of Fish and Wildlife); Lynda Boyer (Heritage Seedlings, Inc.); Claire Fiegener (Greenbelt Land Trust); and Mike Robinson, Dave Rand, and Tom Sanak (property owners). In addition to the folks mentioned above, several people went out of their way to show us population locations and share their expertise. We would not have been able to complete the Delphinium leucopheum chapter without the enthusiastic help of Dr. Keith Karoly (Reed College). Dick Brainard of Salix Associates generously shared all of his rare plant survey data for the Muddy Creek (Allan and Allan) property. Sally Villegas provided maps and population data for many sites within the West Eugene Wetlands complex. Chris Seal provided maps and directions for numerous populations within the Central Willamette Valley National Wildlife Refuges. Carolyn Menke and Tom Kaye of the Institute for Applied Ecology cheerfully shared their knowledge of selected prairie species and their populations. Finally, the authors would like to thank the staff and volunteers at ODA’s Native Plant Conservation Program. This project would never have been completed without the hard work, flexibility, and sense of humor exhibited by each person who participated in the field work: Kelly Amsberry, Brian Basor, Melissa Carr, Troy Maddux, Liz Martin, Stephan Meyers, Linda Moore, Ian Silvernail, and Rhiannon Thomas. Although all of the ODA field staff took amazing photos of our study sites and species, special mention must be given to Melissa Carr and Brian Basor for their patience and attention to photographic detail. Linda Moore deserves special recognition for contributing the species background information for the Lathyrus holochlorus chapter. Table of Contents Chapter I.

    DCDB: an updated on-line database of chromosome numbers of tribe Delphinieae (Ranunculaceae) Maria Bosch1, Joan Simon1, Jordi López-Pujol2 & Cèsar Blanché1 1BioC-GReB, Laboratori de Botànica, Facultat de Farmàcia, Universitat de Barcelona. Av. Joan XXIII s/n. 08028 Barcelona, Catalonia (Spain) 2BioC-GReB, Botanic Institute of Barcelona (IBB-CSIC-ICUB). Passeig del Migdia s/n. 08028 Barcelona, Catalonia (Spain) VERSION 2.0 UPDATED 23/IV/2016 Abstract. A new version of the earlier chromosome database of tribe Delphinieae (Simon, J., M. Bosch, J. Molero & C. Blanché. 1999. A conspect of chromosome numbers in tribe Delphinieae (Ranunculaceae). Biodiversity Electronic Publications, 1 [Available online at http://hdl.handle.net/2445/95875]) is presented, after an accurate extensive literature and Internet survey, by adding the chromosome counts for the genera Aconitum L. (including Gymnaconitum (Stapf) Wei Wang & Z. D. Chen), Delphinium L. (including Staphisagria Spach), Consolida (DC.) S.F. Gray and Aconitella Spach, accumulated in the last 17 years. A total number of 2598 reports are presented, belonging to 389 species, representing a 44.5% of the total species number of the tribe (an increase of c. 137% compared with the 1097 reports gathered in the 1999 version). This increase is due both to chromosome research progress (analysed as counts/year) and an improved information capture system (including checking of populations location through Cyrillic alphabet, and Japanese and Chinese writing systems). Additionally, recent taxonomic advances, synonimization and new phylogenetic criteria have also been taken in account. The main basic number x = 8 is found at 2x, 3x, 4x, 5x, 6x, and 8x ploidy levels, whereas x = 9 is much rarer.

    Peacock larkspur (Delphinium pavonaceum) ENDANGERED Flowers (left), habit (center), and habitat (right) of peacock larkspur. Photos by Melissa Carr. If downloading images from this website, please credit the photographer. Family Ranunculaceae Taxonomic notes The Flora of North America North of Mexico treats peacock larkspur as a hybrid between Delphinium menziesii ssp. pallidum and D. trolliifolium. However, based on its unique morphology and fertile, self-sustaining populations, peacock larkspur is treated here as a distinct species (D. pavonaceum), following the Oregon Flora Project treatment of the taxon. Peacock larkspur has been reported to produce viable hybrid seeds when crossed with Delphinium leucophaeum, D. menziesii, D. oreganum, and D. nuttallii. Plant description Peacock larkspur is a leafy perennial 30-90 cm tall that grows from a cluster of globose tubers. The deeply cleft leaves are mostly cauline, becoming bract-like above, the lowest leaves with petioles up to 22 cm long. Flowers are arranged in a pyramidal raceme, with lower pedicels much longer than the upper ones. The sepals are white to cream, sometimes slightly greenish blue on the back and greenish at the tip, and more or less reflexed to spreading. The lower petals are white or faintly bluish tinged toward the base and glandular-pubescent with a hairy tuft at the base of the blade. The upper petals are bluish to lavender-tipped. The follicles are up to 1.6 cm long and often glandular-pubescent. Distinguishing characteristics Peacock larkspur is distinguished from Delphinium leucophaeum, the only other white- flowered larkspur west of the Cascades, by its taller habit (30-90 cm versus 20-60 cm in D.

This is a commercially marketed species; therefore, adding working weights and a pure seed unit definition to the AOSA Rules will standardize seed testing procedures among laboratories. The proposal includes reclassification of the species classis from ‘weed’ to ‘range and revegetation’ and from ‘weed’ to ‘other crop’ as the contaminating classification under ‘range and revegetation.’ Supporting Evidence: Slender cinquefoil is a tufted native perennial growing from a short thick rhizome. This member of the rose family (Rosaceae) is composed of a taxonomically challenging complex of botanical varieties found in a wide variety of habitats from Baja California to Alaska in the west and eastward through the northern Great Plains and Great Lakes Basin and Quebec.

Because of the poorly known status of a species of possible conservation concern, discussion beyond what has previously been published, including infraspecific variation, is provided here. As treated in FNANM, the species comprises pinnate- leaved, sparsely to non-tomentose Potentilla occurring on “sky islands” in central and eastern Oregon and northern Nevada, specifically Gearhart, Steens, Greenhorn, Strawberry, Wallowa, and eastern Cascade mountains of Oregon, and the Ruby Mountains of Nevada. Populations from ultramafic substrates in the Greenhorn and Strawberry mountains tend to have more leaflets, more diffuse inflorescences, and smaller flowers than elsewhere; they are described here as Potentilla versicolor var. darrachii Ertter & DiNicola, var. nov. Other infraspecific variation in the species is currently under investigation by the second author. As the first continent-wide revision of Potentilla since Rydberg (1908), the treatment of the genus in Flora of North America North of Mexico (FNANM) by Ertter et al.
