Abstract

 

The study was conducted from August 2020 to February 2021 to evaluate the recovery of damaged vegetation 15 years after the Typhoon Durian (2006) for cleaned and un-cleaned broken plant biomass. Testing areas were planned at plot 8, lot E10, 17th sub-zone, including original forest (F), un-cleaned damaged forest (G), and cleaned damaged forest (R). The study analyzed the number of species, the Shannon-Wiener diversity index (H'), the evenness index (E), and the Simpson dominance index (D). The species recorded were 9, 9, and 11 for areas F, G, and R, respectively. Rhizophora apiculata Blume was dominant of all areas. Additionally, Avicennia alba Blume was recorded as dominant in the damaged areas. Secondary succession of the damaged vegetation tended to be a multi-species community. However, this study found no significant difference in diversity indices between the G and R areas. Therefore, it was recommended to monitor the vegetation in a longer term for a comprehensive assessment of the consequence of cleaning or not cleaning the broken plant biomass from the forest after natural incidents.
