Salix Associates 2525 Potter, Eugene, OR 97405 / 503.343.2364 / FAX 503.683.4501 ( ; Survey for Lomatium bradshawii in Amazon Park March -April 1994 Project Description The City of Eugene Engineering Division contacted Salix Associates to search for and map occurrences of Lomatium bradshawii within the study area of Amazon Park shown in Attachment A. The study area includes an area surrounding a berm which is proposed for removal. It does not include the major populations of the plant within the park. Methodology Surveys for Lomatium bradshawii were conducted on March 22 and 28, and April 11, 1994. These survey dates included the peak flowering time, as well as just before and just after peak flowering. Tight meander patterns were followed in searching for the plants, and extremely thorough coverage was given in all suitable habitats. Special attention was given so as to locate the greatest number of immature, non - flowering plants possible. A substantial portion of the plants located were in this category. . Results The attached map shows locations of plants found within and near the study area. Approximately 370 plants were located in the study area, and additional subpopulations were noted nearby in areas D and E, and a portion of area A, as marked on the map. During the course of the survey it was estimated that the number of plants extant in the major populations of Lomatium bradshawii in the park is between 2500 and 5000. The recorded number for the park population is only 750 (see Recovery Plan: Bradshaw's Lomatium ( Lomatium bradshawii), USFWS 1993). The recovery plan suggests that accurate population counts should be made, and permanent plots should be established to monitor population trends. This is perhaps of special interest in this case of Amazon Park as it is the only large population of the plant which is maintained by mowing.
