While the above clearly illustrate the high biodiversity in the Asia-Pacific region, it is important to note the large discrepancy in the availability and quality of data, both regionally and subregionally (Kier et al., 2009; Meyer et al., 2015; Mihoub et al., 2017; Amano & Sutherland, 2013). Reliable data is still only available for some taxonomic groups. For example, maps showing alpha diversity, the extent of endemism, and biodiversity hotspots are usually only available for plants (Joppa et al., 2013), mammals (Schipper et al., 2008), birds (Stattersfield et al., 1998), reptiles (B.hm et al., 2013), and amphibians (Stuart et al., 2008). Other highly diverse species groups are less well-researched and understood (Kiel, 2010). When it comes to marine biodiversity, there are still significant gaps about the status of several important species and ecosystems (e.g., Costello et al., 2010; Selig et al., 2014).
