Data
Counties are identified in the Atlas by the year that a dogwood anthracnose infection is first confirmed by laboratory culturing of the fungus Discula destructiva. Confirmation of an infection may come from anyone that discovers an infected tree and has it confirmed in a laboratory. Counties in the Southeast with a confirmed infection were mapped starting in 1987 and continuing to the present year. Counties where all the diseased trees have been removed and no evidence could be found of the disease for two years are mapped as being free of the disease. Seven states in the southeast have counties with confirmed infections.
The following data items are present in the dogwood anthracnose section of the Atlas:
- FIPS - Numeric code to identify the state and county
- State_name - The name of the state containing the county
- Cnty_name - The name of the county
- Year - The year dogwood anthracnose infection was confirmed (Value of zero means there has been no infection confirmed)
NOTE: All other data items are used internally by the Geographic Information System software to track the data record.
