Replication data for: Developing a Georeferenced Database of Selected Threatened Forest Tree Species in the Philippines

Georeferenced species occurrence is a prerequisite in species distribution modeling and species ecosystem correlation analysis and also aids in tracking plant species and prioritizing scarce resources for conservation. The Global Biodiversity Information Facility, legacy literature of biodiversity, contemporary literature, technical reports and biodiversity surveys are important sources of species occurrence data waiting to be georeferenced. In this paper, we discussed a method used to georeference occurrences of threatened forest tree species from the above sources. Locality descriptions were initially narrowed down in geographic information system using administrative maps and further confined using two criteria: 1) elevation and 2) surface cover information from remotely-sensed images. The result was a georeferenced database of 2,067 occurrence records of 47 threatened forest species on a national scale . Each record had a unique point feature per species and enough metadata directing the database user to the source of occurrence data. The database can be used as a tool in determining priority species for specimen or germplasm collection, for taxonomic identification and historical mapping. It also serves as an integral component in spatially modeling the distribution of tree species and forest formations in the past and in a possible future scenario.
