摘要：

The Matang Mangrove Forest Reserve (MMFR) has been under silvicultural management using a 30-year rotation cycle since 1902. Whereas two artificial thinnings in 15 and 20-year-old stands yield mangrove poles, the clear-felled greenwood from 30-year-old stands is used for charcoal production. Although the reserve appears to be (economically) sustainable in terms of wood production, there is insufficient information on mangrove regeneration and growth dynamics within the MMFR to confirm this. In the present study, we investigate changes in mangrove regeneration rates after clear-felling by analysing a Landsat time-series (1986-2016) using the BFAST algorithm. We created an image-stack from 1986 to 2016 and calculated different vegetation indices (e.g. NDVI) for each image. Based on the vegetation indices, we could identify the clear-felling activities and observe different trends in the mangrove regeneration rate. We will further analyse the time series using the trend and seasonal components of the BFAST algorithm.
