This is a computational infrastructure for biogeographic regionalization (the classification of geographical areas in terms of their biotas) and spatial conservation in the R scientific computing environment. Previously it was only possible to perform analysis of biogeographic regionalization on small datasets, often using tools that are difficult to replicate. With macroecological datasets of ever increasing size and complexity, phyloregion offers the possibility of handling and executing large scale biogeographic regionalization efficiently and with extreme speed. It also allows fast and efficient analysis of more standard conservation measures such as phylogenetic diversity, phylogenetic endemism, evolutionary distinctiveness and global endangerment. phyloregion can run on any operating system (Mac, Linux, Windows or even high performance computing cluster) with R 3.6.0 (or higher) installed.

phyloregion is available from the Comprehensive R Archive Network, so you can use the following line of code to install and run it:


Alternatively, you can install the development version of phyloregion hosted on GitHub. To do this, you will need to install the devtools package. In R, type:

if (!requireNamespace("devtools", quietly = TRUE)) 



Load the phyloregion package and you are good to go:
