EMERALD CHAPTER - NPSO MAY 1995 <br /> Report on Population Survey <br /> of Lomatium bradshawii at Amazon Park, <br /> Eugene, Oregon <br /> • <br /> Introduction <br /> The City of Eugene and the Emerald Chapter of the Native Plant Society of Oregon (NPSO) <br /> undertook a cooperative venture to survey flowering plants in the main population of <br /> Lomatium bradshawii (Bradshaw's desert parsley) in Amazon Park in south Eugene. The <br /> area is located in T18S, RO3E, Section 5, SW 1/4, (Lane County). The area occupied by <br /> this population can be described generally as the meadow on the south side of Amazon <br /> Parkway adjacent to the community gardens (south 1/2), and the area on the north side of <br /> Amazon Parkway, between the Parkway and the woods (north 1/2; see Attachment A). A <br /> few plants are located in the ash woods in the north 1/2, probably persisting from before the <br /> establishment of trees. <br /> NPSO members familiar with the population believed that the estimate of 750 flowering <br /> plants listed in the recovery plan for the species was low, and that the population needed to <br /> be systematically sampled and updated. The City of Eugene funded the field sampling <br /> portion of the project and statistical analysis as de facto mitigation for destruction of plants <br /> that occurred when lighting for a running trail was installed. NPSO provided project <br /> coordination. <br /> Satellite populations not included in this survey are as follows. The numbers shown include <br /> flowering and non - flowering plants. The majority of these plants were flowering when <br /> counted. <br /> 1) Just south of the main population, several areas in Amazon Park, on the east side of <br /> Amazon Parkway: approximately 370 plants counted 1994. <br /> 2) About one mile south on the west side of East Amazon Drive: 5 plants counted in <br /> 1995. <br /> 3) About 1/4 mile north on the east side of Amazon Parkway: 19 plants counted in 1995. <br /> Results <br /> The conclusion of the survey is that an estimated 9600 flowering plants are in the main <br /> population of plants in Amazon Park. Probably another 100 -200 flowering plants are located <br /> in the Park to the south of the main population (see #1, above). These smaller sub - <br /> populations were counted in 1994 for another project (Attachment D). For purposes of <br /> general discussion, it is acceptable to use 10,000 flowering plants as an estimate for the <br /> Park. <br /> SURVEY OF LOMA77UM BRADSHAW!! AT AMAZON PARK P. 1 <br />
