Summary

Bromus interruptus, commonly known as the interrupted brome, is a flowering plant in the grass family. It was endemic to southern and central England, but it went extinct in the wild in 1972. After several decades in cultivation, the interrupted brome was re-introduced to Aston Rowant National Nature Reserve in 2004, marking the first known re-introduction of an extinct plant in Britain. The plant was a weed of waste places and arable agriculture, particularly of sainfoin (Onobrychis viciifolia) cultivation. More on Wikipedia ›

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: Native range not verified: no WCVP distribution with native status for this name, so records cannot be told from cultivation and no habitat climate is derived. 42 of the 276 in-range records are 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 they count for the map and its marker.

Natural habitat

No native range: WCVP lists no region where it is native.
Openly licensed records, not tested against the stated range, framed on where they fall.
NativeWCVP lists no region where it is native; the regions it does list are named here. · introduced: Netherlands · regions are the level-3 units of the World Geographical Scheme for Recording Plant Distributions, as Kew's World Checklist records ranges, some under historical names such as Yugoslavia or Czechoslovakia (how).
Extinct inGreat Britain · recorded as extinct by WCVP: history, not habitat; no records are tested against these regions
Kew's description“annual or biennial” · “temperate” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedNo verified native range for this name: WCVP has no entry with native status, and a checklist that only reports presence cannot tell a wild record from a garden one. The map shows 213 openly licensed records of 276 untested against any range; no map marker or climate is derived from them, and no sheet is built from them. 42 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay 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 10 datasets via GBIF.org; each carries its own licence.
