Despite their vital social and ecological value, substantial declines in seagrass communities have been documented in many small islands (Section 3.4.2.5; Arias-Ortiz et al., 2018; Kendrick et al., 2019; Brodie et al., 2020), including Fiji (Joseph et al., 2019), Reunion Island (Cuvillier et al., 2017), Bermuda, Cayman Islands, US Virgin Islands (Waycott et al., 2009), Kiribati (Brodie et al., 2020), Federated States of Micronesia, and Palau (Short et al., 2016), but attribution of such declines to climatic influences remains weak
