“…However, as the size of pixels increasingly exceeds the size of individual plant species, the assumption that spectral species relate to characteristics of individual plants quickly becomes untenable (Chraibi et al., 2022; Féret & Asner, 2014; Féret and de Boissieu, 2020; Gamon et al., 2020; Gholizadeh et al., 2019; Wang et al., 2018). Correlations between spectral diversity and plant species diversity, though often greatly underestimating the latter, have been detected at spatial resolutions ranging up to 30 m (Gamon et al., 2020; Gastauer et al., 2022; Gholizadeh et al., 2019; Kishore et al., 2023; Liccari et al., 2022; Rocchini, 2007; Zhang et al., 2023). However, within the range of spatial resolutions suggested for the SBG mission (30–45 m), such estimates of plant taxonomic diversity presumably will not be useful in certain environments (Rocchini et al., 2022).…”
