County Level Features

All county level features report information that as aggregated to the county level. This include text reference to the county (state/county) and spatial point reference that occur within the county.

Counties with a record: This presence absence map shows a county as green if it has at least one record from any of the evaluated sources.
Sum of records within County: This layer depicts the total number of unique records of a species across all sources within a county.
Counties listed in USDA Plants and/or Bonap Only (No occurrence points) These counties only contain a reference from USDA Plants and/or BONAP. There are no identified iNaturalist, herbarium, or germplasm occurrences from these locations.
Counties with one or more Herbarium or Germplasm Occurrence: : hese counties have at least one herbarium and/or germplasm occurrence. There may also be additional records within this county(iNaturalist, USDA Plants, BONAP, NatureServe).
Counties with iNaturalist Observation only: These counties only have species observations from iNaturalist.

Occurrence Features

Germplasm Occurrences: : Occurrence data with living specimens stored in a Genebank or Botanical Garden.
Herbarium Occurrences with web url: Occurrence data of herbarium specimens, which includes an url for the source herbarium data.
Herbarium Occurrences without web url: Occurrence data of herbarium specimens.
iNaturalist observation data:: Research grade observations from iNaturalist.

Assigning the State and County to each occurrence

When latitude and longitude data was used to assign the state/country when possible. If no latitude and longitude data was provided, the state and county names were pulled from the attribute data associated with the record. If a state or county name could not be assigned by either method the record was excluded from this analysis.

Flora of North America

If state level distribution information was provided for a given specific species, that information was used to filter the states in which counties are evaluated.
