Characterizing Spatial Distribution and Environments of Sumatran Peat Swamp Area Using 250 M Multi-temporal MODIS Data

Abstract

Recently, the awareness on the wetland ecosystem change in tropical regions has increased considerably, especially in highly sensitive/vulnerable areas such as peat swamp area. This study investigated the vegetation temporal patterns in peat swamp area based on multi-temporal MODIS data. We identified 23 types of significant patterns that were characterized by land cover type and peat depth. They indicate different type of ecosystem and/or different response of ecosystems to the changing environment in the areas. Considering the results, the peat swamp ecosystems can be categorized into two types, as follows: (1) developed land as the industrial forest plantation and other plantations, and 2) secondary swamp forest and swamp bush. Moreover, several patterns have changed significantly in secondary swamp forest ecosystem with a very deep peat have been identified that support natural tree covers and represent important ecosystem to be preserved. Characterization of the peat swamp area will provide baseline information on this ecosystem type and to develop management strategies to foster resilience in the remaining peat swamp forests.
