The survey has identified 42 fish species in 16 families, 8
orders; 43 species of mushroom of 30 genera, 19 families;
103 plant species of 43 families; 41 soil fauna species of
25 families, 35 genera; 59 zoobenthos species of 52
BIODIVERSITY AND NATURAL RESOURCES PROTECTION
genera, 40 families; and 114 species of algae. The main
factors impacting to the biodiversity were potentially land
use changes with high frequent disturbances and using
high amount of agrochemicals. The result also found that
many species can be indicators for land use change or
environmental change.

Soil quality results showed the difference along the length of the island in association with
unbalance of TN, TP and TK amount were resulted of unproper use in agrochemical during farming

Water’s sample location at the first and second time
There was significantly increasing EC and Salinity parameters in dry season due to saline intrusion.
By contrast, parameter of pH, TN and TP were pretty stable over time and space. Farming
cultivation activities are exposing potential negative impacts on water and soil quality.
