Mostly all of corals was died due to coral bleaching and red tide in 1997. g • Permanent transect data in 1995 and several studies of students become a good comparison studies of students become a good comparison data about coral recovery process. • Actually we have 6 islands as a place of Actually we have 6 islands as a place of permanent transect, it’s only 3 islands could be compared according to time series data p g
METHOD • Permanent Permanent transect established in 1996 by transect established in 1996 by Coremap I, data recorded by using LIT method. • PhD study (Jann Henning Steffen), using video belt transect (in 1996, 2001 and 2007) • Bung Hatta Univ (Yunaldi Yahya, in 1996 and 2007). • Yayasan Minang Bahari, using LIT method in 2008.
