  2. Due to the large discontinuous distribution of mangroves in Guangdong zhanjiang mangrove national nature reserve ZJ(G/L), Two representative separated mangroves were selected in Gaoqiao (109° 44′ E–109° 56′ E, 21° 9′ N–21° 34′ N,ZJG) and Leizhou (110° 6′ E–110° 30′ E, 20° 48′ N–21° 7′ N, ZJL), the core areas of the reserve for research.
