[5] UNEP World Conservation Monitoring Centre described garrigue as "discontinuous bushy associations of the Mediterranean calcareous plateaus, which have relatively alkaline soils.
[9] The fines (charred wood and smoke residues, or charcoal dust) of periodic brush fires also have had an effect on the patterning and composition of the garrigues.
Garrigue is a common general word for the shrubland habitat ecosystems in southern France along with maquis, which are known elsewhere in the Mediterranean region as matorral and tomillar in Spain, macchia in Italy, phrygana in Greece, garig in Croatia, and batha in Palestine or horesh in Israel.
Maquis shrubland is broadly similar to garrigue, but the vegetation is denser, being composed of numerous closely spaced shrubs.
Deforestation of the indigenous oak forest since the Late Bronze Age, for cultivation of olives, vines and grain, the introduction of sheep and especially goats and charcoal-making for heat and iron-working, exposed the land surface to weathering and resulted in erosion of the topsoil.
[13] The dense, thrifty growth of garrigue flora has recommended many of its shrubs and sub-shrubs for uses as ornamental plants in traditional and drought tolerant gardens.
Grapes that are grown in the garrigues region of France are said to produce wines with a "barnyard" or "earthy" tone, or "the herbal scent of lavender that fills the hills of Provence in the summer time.
