N1 - Funding Information:
This research was funded by BELSPO (Belgian Science Policy Office) in the frame of the STEREO III Programme—Project Managing Mangrove Forests with Optical and Radar Environmental Satellites (MAMAFOREST) grant number SR/00/323. We thank the Steering Committee members Marc Simard (NASA-JPL), Tiejun Wang (Universiteit Twente) and Daniel Friess (National University of Singapore) for their independent assessments and Joost Vandenabeele and Jean-Christophe Schyns for Belspo STEREO III Programme Management. We also thank the Perak State Forestry Department and the local rangers of the MMFR for their support during the fieldwork and for providing the management plans of the reserve. Finally, we thank Muhammad Amir Bin Fisol, Emilia Ashari and Columba Martínez-Espinosa, for their collaboration with field work. This study was carried with the approval of the Perak State Forestry Department, Ipoh, Malaysia. LANDSAT Surface Reflectance products courtesy of the US Geological Survey. The authors would also like to thank both the University of New South Wales and the European Regional Development Fund (ERDF) Sêr Cymru programme for providing support to R. Lucas. The Japan Aerospace Exploration Agency (JAXA) Kyoto & Carbon Initiative are thanked for providing the L-band SAR data for the study as are members of the EU's BIOSOS and Ecopotential Projects, the Aberystwyth University Living Wales Team and Geoscience Australia.

N2 - Expansion of rotational timber harvesting of mangroves is set to increase, particularly given greater recognition of the economic, societal and environmental benefits. Generic and standardized procedures for monitoring mangroves are, therefore, needed to ensure their long‐term sustainable utilisation. Focusing on the Matang Mangrove Forest Reserve (MMFR), Perak State, Peninsular Malaysia, thematic and continuous environmental descriptors with defined codes or units, including lifeform, forest age (years), canopy cover (%), above‐ground biomass (Mg ha−1) and relative amounts of woody debris (%), were retrieved from time‐series data from spaceborne optical and single/dual polarimetric and interferometric RADAR. These were then combined for multiple points in time to generate land cover and evidence‐based change maps according to the Food and Agriculture Organisation (FAO) Land Cover Classification System (LCCS) and using the framework of the Earth Observation Data for Ecosystem Monitoring (EODESM). Change maps were based on a pre‐defined taxonomy, with focus on clear cutting and regrowth. Uncertainties surrounding the land cover and change maps were based on those determined for the environmental descriptors used for their generation and through comparison with independent retrieval from other EO data sources. For the MMFR and also for other mangroves worldwide where harvesting is occurring or being considered, a new approach and opportunity for supporting management of mangroves is presented, which has application for future planning of mangrove resources.
