Machair

A machair (; sometimes machar in English) is a fertile low-lying grassy plain found on part of the northwest coastlines of Ireland and Scotland, in particular the Outer Hebrides. The best examples are found on North and South Uist, Harris and Lewis. Etymology Machair is a Gaelic word meaning "fertile plain", but the word is now also used in scientific literature to describe the dune grassland unique to Western Scotland and north-west Ireland. It had been used by naturalists since 1926, but the term was not adopted by scientists until the 1940s. The word is used in a number of Irish, Scottish and Manx placenames to refer to low-lying fertile ground or fields, even in areas where no machair has ever been supported. In Scotland, some Gaelic speakers use machair as a general term for the whole dune system, including the dune ridge, while others restrict its use to the extensive flat grasslands inland of the dune ridge. In Ireland, the word has been used only in place-names, and the habitat's existence there was only recently confirmed. In Manx Gaelic, 'magher' is a common term for a field. In 1976, an effort was made to strictly define machair, although a number of systems still evade classification. This proved difficult when the habitat was listed on Annex I of the Habitats Directive in 1992, leading to the distinction between "machair grassland" and the "machair system". Geography
