Summary

Avena byzantina, red oats, is a species of cultivated oat in the family Poaceae. It is native to Greece, Turkey, Cyprus, the Transcaucasus, Iran, and Saudi Arabia. Cultivated for thousands of years, it is better suited to warmer conditions than white or common oats (Avena sativa), but is often sown as a no‑till winter crop. There are 564 landraces and 203 cultivars of red oats listed in the European Plant Genetic Resources Search Catalogue (EURISCO). More on Wikipedia ›

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 1 in-range record, none placed to within 10 km. 1 of the 1 in-range records is placed to worse than 10 km, or to no stated accuracy and fewer than three decimals or by something other than a person's observation, and cannot place a climate cell, though it counts for the map and its marker.

Evidence usedThe map marker rests on the one georeferenced record inside the native range, openly licensed and shown on the map. 248 records outside the WCVP native range not used. Under a dozen records behind the map. No climate across the range is derived for this species. 1 in-range record is placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stays on the map but off the climate.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 58 datasets via GBIF.org; each carries its own licence.
