Project Title: Impacts of alien herpetofauna on the local ecosystem in Hong Kong

Applicant: Dr Yik-Hei SUNG, Hong Kong Baptist University

Total Approved Grant: $367,480

Duration: 1/3/2016 to 31/12/2017

Project Status/Remarks: On-going

This project aims to assess the ecological impacts of alien herpetofauna species on the local ecosystem so as to formulate proper measures to control alien/invasive species in Hong Kong. Its objectives are:

1. To investigate the population occupancy and population density of Green House Frogs in Hong Kong, particularly in the native distribution of Romer's Tree Frogs including Lantau Island, Lamma Island and Po Toi Island;
2. To identify morphological characters to distinguish native and introduced Chinese Bullfrogs by genetic analysis;
3. To investigate the population density, population structure of Chinese Water Dragons; and
4. To investigate the diet of Green House Frogs, released Chinese Bullfrogs and Chinese Water Dragons so as to evaluate their impacts on other native animals.

The information yield in this study will facilitate formulation of proper measures to control alien herpetofauna.

Summary of the Findings/Outcomes:
To be available upon completion of the project
