Abstract:

Species assessment - determined species did not meet the definition of endangered or threatened under the Act and, therefore, was not elevated to Candidate status. Information current as of: September 20, 2007. <br> Note: This Candidate Assessment was initiated in 2004, shortly after the species was described. Completion of the Candidate Assessment was held in abeyance, pending further surveys to substantiate incomplete information indicating potential for additional populations. In 2007, FWS candidate conservation funds were made available to conduct further survey work. Surveys were conducted during summer 2007, and a final report is due in May 2008. Although genetic analyses are not yet complete, morphological evidence of the samples collected leads the botanists who described this species to conclude preliminarily that Botrychium tunux is much more abundant than originally believed. Therefore, [U.S. FWS] have determined that elevation to Candidate status for Botrychium tunux is not appropriate at this time. This determination may be reconsidered following receipt (in May 2008) of report analyzing genetic composition of samples collected in 2007. <br> The status assessment, largely completed in May 2004, reflects [U.S. FWS] thinking at that time; updates based on 2007 findings have been included. Specifics on the locations of additional B. tunux populations cannot be provided at this time, but will be available in the final report.
