Help Needed with Old "Thyme" Common Names - Sue Kolar

Are you a local history buff? Do you know the common names of some of Oregon's native flora? We need your help! The Oregon Natural Heritage Program is currently working on a project to map the vegetation of the Willamette Valley (W.V.) and surrounding foothills, as well as Sycan Marsh, as they were when European settlers began to arrive. Our primary source of information is survey records from the mid-to late-1800's. While these records contain a wealth of information about the pre-European settlement landscape, the surveyors used common names to describe the various plant species they encountered along the way. While many of the names are still in use today, or are self-explanatory, others are quite obscure. Following is a list of some common names, the location and habitat where they were found, and their presumed growth habit. If you think you know the scienlific names for these plants (or even have an interesting guess), we'd love to hear from you. Drop a card to: Oregon Natural Heritage Program, 821 SE 14th, Portland, OR 97214.

Endangered Species Listing in Oregon - Stu Garrett

As a result of the changing priorities of national politics, important changes have taken place in how rare plant species are treated in Oregon. It is important that NPSO members have an understanding of what is happening. In February, 1996, the U.S. Fish and Wildlife Service (USFWS) published a new candidate notice of review, which outlined a major new direction the agency was taking in its efforts to address the Endangered Species Act (ESA). In this notice of review, the number of plant species which were considered potential candidates for listing in Oregon under the ESA dropped from 136 to 5. This change has profound implications for the management of sensitive plants on public lands in Oregon.

The USFWS cited a number of reasons for the change in the definition of candidates, and the species included. Until this year, they had two main types of candidates for listing under the act. The notice of review regularly included C1 candidates, defined as those species which were candidates for listing under the ESA, and for which the Service had suificient information to list. This list was fairly small (in Oregon there were 26 plant species which were C1 candidates), and included the taxa which had the highest priority. The second main category was for C2 candidates, defined as species which may be threatened or endangered, but which needed additional inforrnation (on their distribution, abundance or threats) before they could be listed. The C2 list was much larger, containing over 110 plants in Oregon. The Service also included extinct (3A), potentially extinct (C2*), species dropped because of questionable taxonomy (3B), and taxa dropped because they do not meet the criteria lor listing (3C). These latter categories had no real implications since they did not include species considered for listing. Under the old policy, the other federal land management agencies included all C1 and C2 plant taxa on their sensitive species lists, and tried to manage these plants to assure they would not need to be included on the endangered species list.

The first change in the listing process occurred as a result of a memo from the director of the IJSFWS, Molly Beattie. She decided the C2 list needed to be changed from a Candidate list to a list of Species of Concern. Mainly, the view was that the list was so large (clearly containing many more species than could ever be listed under historical work patterns) that the Service was spending too much of its limited time and resources on species which had lower priority for protection. This change also brought the USFWS in line with the way the National Marine Fisheries Service (NMFS) was addressing candidates. It was decided there would be only one category of candidates, and that it would include former C1 taxa, with the Cl list revisited to make sure it contained the Service's highest priority for listing. The C2 list would be dropped, and a Species of Concern list would take it's place. These lists would be similar, but they would not be published nationally. Instead they would be developed and maintained (but not published) by the various USFWS Field Offices. The law suit to list C1 taxa (which NPSO participated in) clearly was involved in this change, since it created an enormous backlog of work for the USFWS, with the public perception that they were not managing the Act correctly.

Once this change became official, the Service quickly moved to update the candidate notice of review. This included a review of the status of all former C1 taxa, to determine if they should remain as Candidates. The review took place at USFWS regional offices. Oregon is part of Region 1, with headquarters in Portland. Region 1 includes Washington, Idaho, Nevada, Oregon, California and Hawaii. Largely because of California and Hawaii, Region 1 has most of the listed, proposed and candidate species in the U.S. (although Nevada and Oregon are near the top of the list for the number of C1 and C2 candidates).

The process for this review was that each of the state offices was to develop a candidate status sheet for each C1 candidate, outlining the threats, reasons for listing, and listing priority. The USFWS state biologists had completed these before, but had very little time to spend, given the large number of species being reviewed and the small work force.

The overall result of the process was that one person in the regional office decided that only five plants in Oregon, two in Washington and one in Idaho warranted inclusion on the Candidate List. There were a number of reasons for this. First, in Oregon, botanists recommended a number of new species be moved to the Cl. These recommendations appear to have been mysteriously lost by the USFWS. The person making the recommendations, Jim Bartel of USFWS, believed that species occurring on public lands were inherently protected, and discounted threats related to public land management. (In California this might be true, but in the Northwest it is clearly not accurate.). Finally, the field office staff did not understand that they were trying to convince a skeptic that a species needed to be included on the list. Rather, they believed that their judgement and the priority number assigned to the species was critical. As a result, most of the Oregon species have been dropped.

Hopefully, we can correct some errors. The candidate list no longer includes all of Oregon's species which are high priority for listing under the act. High priority taxa need to be added, and federal and state agencies are working to be sure this happens. Secondly, a species of concern list should be developed, and federal agencies (BLM and USFS) need to adopt rules and regulations which incorporate this list into their planning and management activities in the same way they have previously used the candidate list. Rare plant conservation in Oregon has been set back. We will all need to be more vigilant in our pursuit of protection for Oregon's rare species and habitats.

Concerns about these changes should be addressed to Mr. Michael Spear, Regional Director, U.S. Fish and Wildlife Service, 911 NE 11th, Portland, OR 97232. He should be made aware that simply because a plant occurs on public land, that doesn't mean it will be adequately protected, and that the agency should re-review the previous candidates that were dropped for this reason.

Willamette Valley Chapter Officers - Mark Quistad

Attention! We need to select new officers: president, vice president and treasurer. Both the vice president and I feel that two years of service is enough. In 1997 we will be hosting the NPSO annual meeting, on June 7-8, at the Silver Falls Conference Center. If you are interested in any of these offices, or can help with annual meeting, please call Mark Quistad. Our meeting in September will be a working meeting that will be open to anyone wishing to attend. Further details on that meeting will be in the September Bulletin.

The Oregon Flora Project Update - Scott Sundberg

From its inception, there have been close ties between the Oregon Flora Project and the NPSO. Many NPSO members have sent us information or specimens, volunteered, or helped lead the project. Most financial donations have come from NPSO members and NPSO state officers have awarded the project three generous grants, most recently $1,250 last January. We have also received grants from the Emerald and Umpqua Valley Chapters. We are deeply grateful for the financial support we have received from the NPSO and for the close relationship we've enjoyed over the last two years.

The project's goal is to produce a flora of Oregon and an Oregon vascular plant atlas in printed and computerized forms. At the completion of the project, plant enthusiasts will have an illustrated flora of the vascular plants of Oregon, including identification keys and species descriptions. No longer will we have to use a variety of references for identifications. The atlas will, for the first time, show detailed information on the distribution of all our vascular plant taxa. Computerized versions of the Flora and Atlas will dramatically alter the ways in which plants are identified and distributions viewed. Use of a multi-entry key will make it possible for people to, in essence, construct their own keys as they identify plants, and will free them from the constraints of traditional dichotomous keys. Visualization of plant distributions as related to patterns of physiographic features, climate zones, and major vegetation types will be possible. The payoffs for our hard work will be great.

Progress on the project as a whole has been steady, although some components are taking longer to complete than anticipated. The Checklist is now 23% done. Completed treatments include most or all of the Asteraceae (Ken Chambers), Cyperaceae (Peter Zika), Astragallls (Aaron Liston), Polemoniaceae (coordinated by Dieter Wilken, with treatments by six authors), Salix (George Argus), Lamiaceae (Henrietta Chambers), Potentilla (Barbara Ertter), and aquatic families (Richard Hales). Smaller groups that have been completed are too numerous to list. The rate of submission of treatments is expected to increase, as several deadlines are approaching.

The Atlas project has drawn a great deal of interest from Oregon's botanical community. In April the revised Handbook for Participants in the Oregon Plant Atlas Project was completed. Field work for the project is being coordinated through the NPSO by Bruce Newhouse and twelve regional coordinators. We have gathered a large number of species lists and are in the process of acquiring many more, as well as one huge data set possibly consisting of over 100,000 records.We have made enorrnous progress on technical aspects of the project, through the efforts of Jon Kimerling, Manuela Huso, and several students and volunteers. We now have a prototype computerized map showing where torrent sedge (Carex nudata) has been observed in the state. Users can click on dots on this map to call up locality, habitat, and collection or observation data associated with the dot. We are particularly excited by cutting edge work being done to construct maps on the fly by accessing the Atlas database and layering distribution data over a series of base maps. Jon Azen and Jon Kimerling have written a JAVA application to accomplish this.

Due to space limitations, it is impossible to list the large number of people who have participated in the Flora project. So far, the project has been entirely a volunteer effort, with the exception of student workers. And given this limitation, we have made a great deal of progress. One of our top priorities over the next few months is to secure funding for a staff of paid workers. This would dramatically increase our productivity.
