Dudley Bluffs twinpod’s clusters of bright-yellow flowers Dudley Bluffs twinpod / BLM Figure 1 Figure 2 bloom for a short time between mid- May and June. Dudley Bluffs twinpod is a close relative of the common sharpleaf twinpod (Physaria acutifolia) and it can be difficult to distinguish the two species at a glance. However, a closer look at the shape of the tiny hairs on the leaves with a hand lens will confirm its identity: Dudley Bluffs twinpod has satellite-dish shaped hairs (see Figure 1) while sharpleaf twinpod’s are star-shaped (see Figure 2). Where does the Dudley Bluffs twinpod occur? Dudley Bluffs twinpod is only known to occur in the general area of Piceance Creek in Rio Blanco County Mountain-Prairie Region Region 6 What can you do to help conserve the Dudley Bluffs twinpod? “Stay the trail” and “tread lightly.” Request information about how to avoid this sensitive species and its habitat at the local BLM or State office.

ACKNOWLEDGEMENTS This research was facilitated by the timely assistance and willingness to share information of many experts. Information provided by the Wyoming Natural Diversity Database (WYNDD) formed the cornerstone of this document, and I would especially like to thank Bonnie Heidel and Tessa Dutcher for their efforts in providing Element Occurrence Records and internal natural heritage program reports. I would also like to acknowledge the use of photos and drawings extracted from earlier WYNDD reports, in particular the photos of Charmaine Refsdal and Walt Fertig, and the drawings of Walt Fertig and Robin Jones. I would like to thank Ron Hartman and other personnel at the Rocky Mountain Herbarium for providing herbarium records and excerpts of relevant student research conducted at the University of Wyoming. Jeff Carroll of Wyoming BLM provided valuable information regarding distribution and threats on BLM lands. Bob Budd provided valuable input regarding populations on The Nature Conservancy’s Red Canyon Ranch Preserve. Walt Fertig (formerly of WYNDD, now with BLM Grand Staircase-Escalante National Monument) was very helpful in providing recent distribution modeling information and discussing the species’ ecology.

  • Status of Physaria Saximontana Var. Saximontana (Rocky Mountain Twinpod) in Central Wyoming
    Status of Physaria saximontana var. saximontana (Rocky Mountain Twinpod) in Central Wyoming, Fremont, Hot Springs, and Park counties Prepared for the Bureau of Land Management – State Office, Lander and Worland Field Offices By Bonnie Heidel Wyoming Natural Diversity Database Dept. 3381, University of Wyoming 1000 E. University Ave. Laramie, WY 82071 6 June 2014 Cooperative Agreement No. L12AC20036 ABSTRACT Systematic surveys of Physaria saximontana var. saximontana (Rocky Mountain twinpod) were conducted in Fremont, Hot Springs and Park counties, central Wyoming of the Bureau of Land Management (BLM) Lander and Worland Field Offices. The taxon is a state endemic that is now known from 32 occurrences in three counties. Three very extensive occurrences are in Fremont County. Two records from two additional counties remain unresolved and the phenomenon of sympatry between species also warrants work. ACKNOWLEDGEMENTS Victoria Pennington, Wyoming Natural Diversity Database (WYNDD) helped conduct Physaria saximontana var. saximontana field surveys, contributed many preparations for 2013 field surveys, and helped in all facets of compiling results. Consultation with Dr. Steve O’Kane is acknowledged with thanks. The Rocky Mountain Herbarium facility (University of Wyoming) and personnel are integral to this and all species studies. Specimens and photos were taken by Rosemary Grinnan and the availability of those specimens was made possible by Tanya Skurski, BLM Lander Field Office, contributing to this study. The support and interest of Adrienne Pilmanis in the BLM Wyoming Office and colleagues in BLM Lander and Worland field offices is greatly appreciated. This work built on the extensive collecting of earlier WYNDD botanists including Hollis Marriott and Walter Fertig.

  • Fifteenth Annual Colorado Rare Plant Symposium September 14Th, 2018 Slocum Commons Colorado Springs, Colorado
    Fifteenth Annual Colorado Rare Plant Symposium September 14th, 2018 Slocum Commons Colorado Springs, Colorado Rare Plant Symposium Moderator: Susan Panjabi (CNHP) G2G3 Species of NE Colorado Session facilitated by Jill Handwerk (CNHP) Reminder: G1/S1 = 1-5 occurrences; G2/S2 = 6-20 occurrences; G3/S3 = 20-80 occurrences. Aletes humilis (G2G3): Jill Handwerk: Secure because mostly on public lands in Boulder and Larimer Counties, numbers have not changed much. Aletes (Lomatium) nuttallii (G3S1): Carol Dawson: Still there at Troublesome Creek. Jill Handwerk: need habitat shot. Aquilegia saximontana (G3S3): Scotty Smith: Found at Lake George, Colorado (lower elevation). Kelly Ambler: Has also seen it at low elevation. Susan Panjabi: We should update elevation range. Brian Elliot: Working with CO 14ers Initative , think it is pretty rare, not found many places, not more widespread than currently think; hard to tell it apart from common species when vegetative. Jill Handwerk: Appears many populations are small (largest is 100 plants) or no number size recorded. Brian Elliot: Wonders if this species should be a G2, given the number of historic occurrences? 1 Astragalus sparsiflorus (G2S2): Jill Handwerk: Used to be only 8 but now are up to 21 occurrences so moved down in rank to G2/S2 with more field work done. Still “sparse” as 10 of those are historical. Bolophyta alpina (Parthenium alpinum) (G3S3): Jill Handwerk: A volunteer for Adopt a Rare Plant found a large population of it for CNHP. Bob Lagire: Has lots of pictures. Steve Popovich: Occurs on a series of escarpments, estimated millions of plants; secure on Pawnee National Grasslands.
