The database for rare plant species endemic to the Southeastern United States was my first large database project. It was started in April of 1999 for part of a presentation at a special session on Southeastern endemics held at the annual meeting of the Association of Southeastern Biologist. The current database was held to a data freeze in 2000 for publication of an overview of the database in a special issue of the journal Castanea associated with this ASB meeting.
This database documents the county level distribution of all vascular plant species endemic to the Southeastern United States that occur in twenty-five or fewer counties. The data were collated from various sources including state floras, taxonomic monographs, and various online databases. The initial publication of this work describes the construction of the database, and gives and overview of the main areas in the Southeast that have a high richness in rare southeastern endemics. I have done additional taxonomic and geographic selectivity analysis of this dataset and would like to publish this analysis at some point in the future.
In Development
The following screenshots were captured in May 2004 from the MS Access version of the Southeastern Endemics database.
The area I chose to study was states entirely south of the glacial maximum and counties that occurred in the humid temperate domain.
Nearly all of the data in the data base was manually entered using the data entry form.
I wrote a number of parsers in Visual Basic to import publicly available data into the SE Endemics database.
Distribution maps for all taxa were generated by ESRI ArcView and are available from within the database.
