Spatial phylogenetic diversity of pteridophytes in Latium (Central Italy): a tool for conservation planning at regional scale

The spatial phylogenetic metrics of pteridophyte diversity and endemism may provide use ful information to prioritize protected areas for conservation planning. We analysed spatial patterns of phylogenetic diversity (PD) and phylogenetic endemism (PE) of native pterido phytes across Latium, to recognise diversity and endemism centres. and to discuss impli cations for conservation in the region. We identified the main PD and PE centres that should be considered as valuable biodiversity hotspots, due to their high evolutionary and conservation value. Most, but not all of them correspond to protected areas Monitoring programmes of the rarest taxa are proposed.
