Description

Quantitative evolution of coastline categorization of Moorea Island from 1977 to 2018. At Moorea, the coastline is characterized by seven main habitat categories (Aubanel et al. 1999): 1/ Rocks and broken stones in their original positions (the rocks, either basaltic or carbonate, are over 50 cm in diameter and broken stones are 5-50 cm in size), 2/ White sand beach (at least 95% of which comprises coral sediments under 1 cm in size and the intertidal zone is not encumbered with vegetation), 3/ Black sand beach (same as white sand but with sediments of basaltic nature), 4/ Muddy areas or herbaceous zones, possibly with mangroves, 5/ Coarse mud-and-sand and detrital substrate with high vegetation area where Cocos nucifera, Hibiscus tiliaceus, Casuarina equisetifolia and Guettarda speciosa grow, 6/ Conglomerate and beach-rock and 7/ Anthropogenic changes (through walls, rocks and/or embankments).
