RECENT FLORISTIC AND SENSITIVE PLANT WORK

IN THE ROCKY MOUNTAINS

July 1996


Ronald L. Hartman, Curator, Rocky Mountain Herbarium, Dept. of Botany (3165), University of Wyoming, 1000 E. University Ave., Laramie 82071-3165

This is a partial update of Hartman 1992 (The Rocky Mountain Herbarium, associated floristic inventory, and the Flora of the Rocky Mountains Project. Jour. Idaho Acad. Sci. 28: 22--43), copies of which are available from the Curator.

Sample copies of three Wyoming plant distribution maps generated with ARC/INFO are attached. This preliminary version was built by Tim Chumley, graduate student in floristics. The data are from the 300,000+ record Rocky Mountain Herbarium (RM) specimen database of recently collected plants (past 18 years). About 80 percent of the database contains Wyoming collection information (the remainder: Colorado, Idaho, and Washington). The data used to generate these maps do not include the most recent studies. Thus, it constitutes about 70 percent of the information now captured for Wyoming. We hope to make postscript files for all 3,000+ Wyoming taxa (5 gigs needed for storage) and place them on the Internet, in part for use by the Flora of North America project (FNA). The symbols will be improved, the boundary for Yellowstone NP added, and a disclaimer attached pointing out that as with any sizable specimen database, some errors in identification exist. It is hoped that making these maps available will alert the systematics community to the new resources available at RM so that more material will be borrowed for FNA and monographic treatments.

An updated map from Hartman (1992, cited above) shows where recent (last 18 years) fieldwork has been conducted by the students, associates, and staff of the Rocky Mountain Herbarium.


This summer, the four thesis projects listed below are in progress (preliminary results are not given):

  1. Mosquito Range east to the foothills and plains (area 27), CO, Tim Chumley, second summer. Funded by Pike NF (Steve Vest), the Colorado Natural Areas Program, and the Colorado Native Plant Society.
  2. Coville National Forest (area 28), WA, Jean Wood, second summer. Funded by the Coville NF, the BLM, and the Washington Native Plant Society.
  3. South-central Wyoming (area 26), Beth Ward, first summer. Funded by the Wyoming BLM (Jeff Carroll on all Wyoming BLM funding).
  4. Shoshone National Forest (area 8; portions of areas 11 and 12), WY, David Rosenthal, first summer. Funded by the Shoshone NF (David Henry and Kent Houston).

Studies completed in the past two years, some await completion of thesis, are listed below. The numbers of collections and taxa and, in bold, the numbers of sensitive taxa and populations/sites, mostly new, are indicated based on the list from the Colorado Natural Heritage Program (CNHP) or that from the Wyoming Natural Diversity Database (WYNDD).

  1. Southern Powder River Basin and Eastern Grasslands (area 3), WY, summers 1993, 1994, B. E. Nelson and R. L. Hartman. Results: 8,170 collections; 958 taxa; 5 Wyoming records; 18 WYNDD taxa with a total of 78 populations. Funded by the Wyoming BLM.
  2. Wyoming/Salt River ranges (area 15), WY, summers 1990, 1992, 1993. R. L. Hartman, B. E. Nelson, and W. Fertig. Results: 15,289 collections; 1,087 taxa; 17 WYNDD taxa with a total of 107 populations! Funded by Bridger-Teton NF and Wyoming BLM.

  7. Southwestern Wyoming and adjacent Utah (area 21), summers 1994, 1995, Charmaine (Refsdal) Delmatier, B. E. Nelson, and R. L. Hartman Results: 8,855 collections; 1175 taxa; 6 Wyoming and 4 Utah state records; 46 WYNDD taxa with a total of 127 populations! Funded by the Wyoming and Utah BLM, Ashley NF (Duane Atwood), and US Fish & Wildlife Service (Chuck Davis).
  8. Gros Ventre/Mount Leidy Highlands (area 13), WY, summers 1994, 1995, R. L. Hartman. Results: 6,591 collections; 822 taxa for Gros Ventre, 570 taxa for Mt. Leidy; 1 state record; 24 WYNDD taxa with a total of 65 populations. Funded by Bridger-Teton NF.
  9. Kemmerer Resource Area (area 15, in part), WY, summers 1990, 1992, 1993, 1994, 1995, T. Cramer, R. L. Hartman, and B. E. Nelson. Results: 5,510 collections; 621 taxa; 16 WYNDD taxa with a total of 39 populations. Funded by Bridger- Teton NF and the Wyoming BLM.

A summary of results is as follows: 80,884 collections; 16 state records; 1 new species; 144 sites for CNHP sensitive plants, 489 sites for WYNDD sensitive plants for a total of 633 sites or populations for taxa of special concern for projects completed in the past two years!

Contributions by associates of the Rocky Mountain Herbarium: Robert Dorn has been making a concerted effort in the past few years to fill in county lists for Wyoming and has been hard at work on his portion of the Salix treatment for FNA; Erwin Evert, Park Ridge, Illinois, 30,000+ collections, is working on a flora of the Greater Yellowstone Area; Walter Fertig, WYNDD, continues to provide the RM with valuable voucher specimens from sensitive plant work; Stuart Markow, seasonal USFS, continues to donate much of his winter months to the RM, he curated the herbaria at the Teton Science School and Grand Teton National Park during the past two years; and Richard Scott, Central Wyoming College, has a major work on the alpine flora of the Middle Rocky Mountains in press (University of Utah Press); Roger L. Williams, Professor Emeritus, History, continues to publish on the history of taxonomy.
