Abstract
The house gecko (Gekko gecko) or tokek is a reptile species known widely used as an export commodity. Overexploitation can threaten wild populations of tokek in the wild. The research was conducted through a Visual Encounter Survey on the islands of Tidung, Pari, and Untung Jawa from 27 November to 02 December 2021. We also distributed questionnaires about the insight and presence of geckos in residents' homes or buildings. The number of respondents have been interviewed are 117 people, while for direct observation the results obtained are 273 individuals. The highest number of geckos was found on Pari Island and the least was on Untung Jawa Island. The house gecko is distributed throughout on these islands and is relatively more abundant in residential areas. The house gecko is most found on power poles and building walls and in breadfruit trees (Artocarpus altilis). Area of The Kepulauan Seribu is about 474562 hectares with a land area of 877 hectares. The population density of tokek based on direct observation was 13.60 individuals/ha. Therefore, the estimated population of tokek; in the Seribu Islands based on direct observations is around 11930.12 individuals.
