Johnson Oklahoma Biological Survey Patricia Folley (ed.) President, Oklahoma Native Plant Society In 1997, the Oklahoma Biological Survey and the Oklahoma Native Plant Society undertook an unusual joint project: the surveying of the plant resources of a preserve recently acquired by The Nature Conservancy. In part this was because of the deep attachment of some of the participants for this nearby and very interesting place. During the early exploration of the “Smith Ranch Site”, as it was called, amateurs and interns were brought in to call out the names of plants as they walked, or in some cases, rode past in trucks. As a rapid assessment, that was probably a good thing, but it certainly wasn’t scientific, and none of those names called could be verified for publication. The Biological Survey allotted the necessary manpower and equipment to conduct a survey structured after the ones being done for several military bases in the area. Frequent, disciplined visits were made to view the diverse habitats as the plants thereon developed over the course of the growing year. One or two specimens of each species was taken, processed, identified and preserved in a public herbarium for the use of future researchers. The herbarium chosen was the Robert Bebb Herbarium (OKL) at the University of Oklahoma, host institution for the Biological Survey. 2002 INTRODUCTION Forrest Johnson of the Biological Survey, Patricia Folley of the Oklahoma Native Plant Society and a co-editor of the Flora of Oklahoma Project, and two fieldassistants, Newell McCarty and Deborah Benesh from the University of Oklahoma’s Bebb Herbarium carried out the fieldwork for the Survey. Almost all processing of specimens, including identification, was done by the late Dr. Johnson. Folley made the identifications of the specimens of sedges, and Benesh and Johnson maintained the databaseand prepared labels. Eventually, over 500 specimens were mounted and placed in the herbarium. Also included in the survey is Plantago rugelii, which was collected by Patricia Folley in 1993 when the site was still known as “Smith Ranch”. Since the survey Folley and others have added a few species, similarlydocumented, to those surveyed in 1997. They are identified by a later collection date in the inventory. No natural living place can ever be fully documented and there are still species known to exist in that preserve that have not yet been found in flowering or fruiting condition. It will no doubt provide interesting work for our successors. After the original introduction was written, an infestation of Lespedeza cuneata (serecia lespedeza) proliferated in the old pastures and a program of removal was begun. The research team is indebted to the kindness and assistance so generously contributed by TNC’s on-site managers, Jim and Hollie Erwin. 66 Oklahoma Native Plant Record Volume 2, Number 1, December 2002 INTRODUCTION In the growing season (March- October) of 1997, The Nature Conservancy’s Pontotoc Ridge Preserve was visited approximately every two weeks by a team of botanists from the Oklahoma Native Plant Society and the Oklahoma Biological Survey for the purpose of preparing an inventory of the plant species on the Preserve. Two to four persons on each visit examined several sites on the Preserve. The number and location of sites varied with the condition of the primitive roads on the property. When roads were muddy, we collected plants at three or four sites along the west side of the Preserve. When the roads were dry enough, we visited several widely separated sites spread over the whole property. At each collecting site members of the team walked separate paths through the area. Any plant in flower or fruit that was not on a list of the plants previously collected or which could not be positively identified was collected. Some trees and shrubs that are usually identified by their leaves, buds, etc., were collected without flowers or fruits. Each specimen was pressed, dried, and fumigated to eliminate insects. Then they were stored in the Robert Bebb Herbarium at the University of Oklahoma. The specimens were identified with the keys and descriptions in Flora of the Great Plains (Great Plains Flora Association, 1986, University Press of Kansas, Lawrence) and Keys to the Flora of Oklahoma, (U. T. Waterfall, 1973, published by the author, Stillwater, OK), then confirmed by comparison with known specimens in the Bebb Herbarium. The specimens from Pontotoc Ridge will remain in the Bebb Herbarium and become part of its permanent collection. Several plant names have been changed since the publication of Keys to the Flora of Oklahoma and Flora of the Great Plains. Names in our list names comply with the PLANTS online database: plants.usda.gov/ plants/qurymenu.html , maintained by the U.S. Department of Agriculture, Natural Resources Conservation Service. We included Johnson, F.L. both the old and new names for a few plants that have had recent name changes. The older name is listed in brackets below the new name. Two status and 17 habit categories are defined by the National List of Scientific Plant Names (1982, U.S.D.A. Soil Conservation Service Publication SCS-TP-159, Washington, D.C.) They are applied as appropriate for each species. The categories and representative symbols used to define status categories are: (N) native and (I) introduced. Habit is represented by one or more of the following: (A) annual; (B) biennial; (P) perennial; (F) herbaceous; (S) shrub; (T) tree; (G) grasslike; (H) partly woody; (W) woody; ($) succulent; (V) vine; (Z) submersed; (E) emergent; (L) floating; (@) tree epiphyte; (+) parasitic; and (_) saprophytic. This information is determined by examining the specimens and consulting the designated floras. These symbols are combined into a convenient status/habit code for each species. For example, NPG = native perennial grasslike; NT = native tree, etc. In the 1997 growing season, we collected 399 species in 261 genera and 79 families. About a third of the species found were in the three common Great Plains families: Asteraceae (composites); Poaceae (grasses) and Fabaceae (legumes). Only about 6 percent of the species are exotic and none of the exotic species is conspicuous or seems to present a threat to the native vegetation. No truly rare plants were found, although Penstemon oklahomensis (S3) and Echinocereus riechenbachii (S2) are present. Based on previous experience, we are likely to have found about 80% of the total plant species present at Pontotoc Ridge. There are probably about 500 plant species in the area. Some perennial plant species do not flower every year, and some annuals vary greatly in abundance from year to year. Continued investigation will result in more species being found. Several field trips to Pontotoc Ridge are planned in 1998. Oklahoma Native Plant Record 67 Volume 2, Number 1, December 2002 Johnson, F.L.
