A second paper has been published by the same UC/JEPS team referenced in a previous news item on this page (April 11, 2017), adding phylogenetic methods to the study of diversity and endemism in the California flora. This novel "spatial phylogenetics" approach makes it possible to evaluate biodiversity from an evolutionary standpoint, including discovering significant areas of neo- and paleo-endemism. Read the open-source paper here.

A new study published by a UC/JEPS team uses distributional data from the CCH and other data portals, diversity metrics, and a randomization test, to map biodiversity and endemism for California native vascular plants. These data are available for research use and includes standardized location and collector names that are not yet avaliable on the CCH. Please see summary here,
