This study aimed at determining the relations between spectral and bird species rarefaction curves in a brutian pine forest ecosystem located in the Fethiye region, Turkey. Bird species were counted by fieldwork in 40 sample plots with 0.81 ha (90 x 90 m). The NDVITOA values of pixels belonging to each plot (pixel numbers are 36, 81 and 324 for Aster, SPOT and RapidEye, respectively) were calculated. Spectral and bird species rarefaction curves were formed by means of EstimatesS software. The relations between spectral and bird species rarefaction curves were examined using regression analyses. Furthermore, the similarities of rarefaction curves were determined considering “increase rate” of curves. The results of study showed that there are serious differences between spectral and bird species rarefaction curves and bird species rarefaction curve was not predicted using satellite images in this region. It is considered that similar studies could be conducted on a wide geographic region using coarse resolution satellite data in order to understand the potentials of spectral rarefaction curves more clearly.
