Field Data Collection at Redang Island, Terengganu

The need to monitor the effectiveness of artificial reefs deployment upon installation is important to assess the degree of success and impacts to surrounding environment. Monitoring guidelines and procedures for artificial reef in tropical marine condition involves data collection around the artificial reef. Divers recorded the coral and fish aggregation around artificial reefs using high performance underwater camera for analyses and identification. From the preliminary coral identification analyses, ten types of different hard coral was found around the reef which dominated by Pocillopora sp. High number of fish assemblages was recorded from the data collection. Most of the fishes present at the study area are identified as coral reef fish species. These result highlight the important and capability of monitoring procedures to assess the success and impact of reef deployment to surrounding environment at tropical marine condition.

Field Data Collection at Pulau Kukup, Johor

Pulau Kukup has been chosen for data collection because of it is known as high-density mangrove species in a total area 6.47 km2 of wetland. Before data collection, Pulau Kukup map was analysed using ArcGIS software. The island has been divided into four quadrant and each quadrant contained 10 random distributed plots to acquire the coordinate. This fieldwork was done from 30th September until 6th October 2020 and involved seven peoples and also a party from Perbadanan Taman Negara Johor (PTNJ). While PTNJ acts as a guide as long as we are on the island. The level of growth of mangrove which is sapling will be identified and recorded within 10m x 10m plot on the acquired coordinate. Identified mangrove saplings within the plot will be pick based on a range height between 1.3-4 m. The tree characteristics such as circumference, height, species and coordinate locations are recorded for further analyses. The picture was also taken for respective parts of sapling which are leaves, roots and trunk. Approximately one kilogram of the soil sample is collected for each sediment sample point and also one kilogram at 0.5 – 1.0 m depth in each plot.
