Karakteristik Biofisik Tempat Peneluran Penyu Sisik (Eretmochelys Imbricata ) di Pulau Anak Ileuh Kecil , Kepulauan Riau

Abstract

A surveys on biophysic characteristic nesting site of hawksbill turtle (Eretmochelysimbricata) in the Anak Ileuh Kecil Island had been conducted. The aim of thisstudy was to identify biophyisical characteristics of the nesting site of E. imbricatain the Anak Ileuh Kecil Island, Kepulauan Riau. Physical characteristics of thenesting site (organic material content, distance between tidal line and first vegeta-tion and the sand’s grain size) were analyzed using Principle Component Analysis(SPSS 10.0.1). The nesting site of the E. imbricata was in the Southern part of theAnak Ileuh Kecil Island. In this area, the slope of the beach was 28,070, the beach iswider than other areas and it has less vegetation. Results of the statistical analysisshown that the organic material content in the substrat, distance between the tidalline and the first vegetation may suitable for the hawksbill turtle for nesting. How-ever, there was a threat for the nesting area as Pes caprae and Barringtonia forma-tion areas are converse into extensive palm oil plantation.
