  1. Natural history collections and locality data

  2. Biodiversity Data in Natural History Collections • 1 billion specimens in 1600 natural history collections • Location information and environmental data • Associated metadata: GenBank accession numbers • Associated collections: DNA, songs, calls

  3. Label Data • Scientific name – including authority • Collector • Location – state, county, specific site, GPS coordinates • Associated species • Notes

  4. Label Data • Scientific name – including authority • Collector • Location – state, county, specific site, GPS coordinates • Associated species • Notes

  5. Locality Data: Callisiagraminea grassleafroseling • United States: Florida: Nassau County. Ralph Simmons State Forest. About 5 miles SE of Folkston, Georgia. From east entrance into Forest, go west and then north on dirt roads. Sandhills with young planted longleaf pines and patchy grass-forb understory.

  6. What’s in a locality • A description of collection location. Written from specific to general, including a specific locality, offset(s) from a reference point, and administrative units such as county, state, and country.

  7. Why do good localities matter? • Collecting data in the field sets the stage for good georeferencing procedures. • Contains useful information for biologists • Future collections, conservation, ecology, taxonomy, niche modeling…..

  8. Occurrence Map • 5,942 occurrences • Over 190 species Overlaid with expert distribution map (Smith and Downs, 1977

  9. Less Precise More Precise x Less Accurate More Accurate What A Locality Should Be • Specific • Succinct • Unambiguous • Complete • Accurate • Precise

  10. Habitat andelevation • Briefdescriptionofthe habitat theorganismwasfound (i.e. Coastalhammock) • Provideanelevationvalue • Reportthesourceofelevation (map, altimeter, seatofpants, etc.)

  11. Coordinates • Itisnotenough to havelocalitydescriptionalone, coordinates are nowessential. • Decimal degrees are recommended. • More decimal places are better.

  12. Examples of Good and Bad Localities • Vague localities • BAD: “Sacramento River Delta” - an extremely large geographic areaBETTER: “Locke, Sacramento River Delta, Sacramento Co., California” - names a town within the Delta • BAD: “3 mi W of San Jose/Cartago border” - without additional details, this would mean anywhere 3 mi W of the borderGOOD: “3 mi W of San Jose/Cartago border on Highway 2, San Jose Province, Costa Rica”
