Records of Narcissus cyclamineus DC. occurrence in the hydrographic basin of River Coura (2007).

Information from field surveys performed during 2007, specifically targeting the detection of the endemic daffodil Narcissus cyclamineus DC. in the hydrographic basinf of River Coura. Includes records of confirmed presences, absences and an assessment of the abundance (expressed as an estimation of the number of inidividuals observed) for the species accross the hydrographic basin. Selection of areas surveyed was supported by an environmental stratification assuring that all potential environmental range of the species accross the hrydrographic basin was covered. Results disclose information from 34 locations surveyed, including points where the species was present (17), and confirmed absences (17). In the locations where the species was present, an estimation of the species abundance (expressed as the number of individuals) is also included.
