Southeast Asia represents a global biodiversity hotspot, and yet compared to much of the rest of the world we have a relatively poor understanding of the patterns of biodiversity and endemism, or even basic distributions for many taxa. Global maps such as the IUCN (International Union for the Conservation of Nature) species range maps often have major inaccuracies in the spatial mapping of species localities, which are particularly problematic around political administrative boundary regions, and make any form of spatial prioritization difficult or impossible.

Here I show various approaches to mapping biodiversity across the landscape, including the mapping of both ecosystems with high levels of endemism, and databasing huge volumes of data as a basis for mapping out species distributions when combined with other forms of data, to map out diversity at numerous different taxonomic levels. I showcase the initial results of mapping for various taxa, and different ways of aggregating the data to better understand different facets of biodiversity. Additionally I discuss various approaches to developing spatial priorities for conservation across the region and the relative tradeoffs between each.
