Maquis Minier
Mining maquis (french: maquis minier) is a type of shrubland biome. It forms on ultramafic rock as a result of forest cover retreat due to repeated wildfires. It is common on New Caledonia. Description Mining maquis covers in New Caledonia, where it is one of the native ecotypes. Most species found in the maquis are native, compared to some regions which are up to 90% introduced species. Plants are evergreen xerophytes and heliophytes, including prostrate shrubs and sedges. ''Araucaria'' and '' Agathis ovata'' can be locally dominant''.'' Mineral composition Soils are excessively poor in phosphorus, potassium and calcium and often abnormally rich in magnesium. This richness in magnesium leads to an imbalance in the calcium/magnesium ratio, in particular in the brown soils located at the base of the massifs which dominate the west coast (Boulinda, Kopéto, Koniambo, Tiébaghi, etc.) Most mining maquis soils also have abnormally high levels of chromium, cobalt, nickel and ...

Anthropization
In geography and ecology, anthropization is the conversion of open spaces, landscapes, and natural environments by human action. Anthropic erosion is the process of human action degrading terrain and soil. An area may be classified as anthropized even though it looks natural, such as grasslands that have been deforested by humans. It can be difficult to determine how much a site has been anthropized in the case of urbanization because one must be able to estimate the state of the landscape before significant human action. Origin The earliest known stages of anthropization can be found as early as the Neolithic era and the basic farmland created in that time. With the continually-growing population of humans, the land that the Earth provides has been appropriated over the years. The ecological footprint created by anthropization is continually growing despite efficiency and technique improvements made in anthropization.. Whether anthropized or not, all land seldom a fe ...

Neocallitropsis
''Callitris pancheri'' is a plant species of the family Cupressaceae. It is endemic to New Caledonia, where it occurs in small, scattered population along rivers. It used to be placed in its own genus ''Neocallitropsis'' but molecular phylogenetic analysis indicated that it was nested within ''Callitris''.Pye, M. G., P. A. Gadek, and K. J. Edwards (2003).

It is an evergreen coniferous tree growing to tall. The leaves are awl-shaped, long, arranged in eight rows in alternating whorls of four; in overall appearance, the foliage is superficially similar to some species of '' Araucaria'', though they are only very distantly related. ''Callitris pancheri'' is dioecious, with separate male and female trees; the seed cones A conifer cone (in formal botanical usage: strobilus, plural strobili) is a seed ...

Beaupreopsis
''Beaupreopsis'' is a genus of plant in family Proteaceae, with just one species in the genus, ''Beaupreopsis paniculata''. It is native to New Caledonia on the south of Grand Terre. Its habitat is from open maquis, to mountain area as low scrub, on a substrate of eroded ultramafic rocks. Characteristics The plants are shrubs, rarely exceeding 1.50 m in height, with thick branches, scattered and few. They have pseudo-whorled leaves (5-10 x 0, 20-0, 60 cm), more or less toothed or lobed at the apex, cuneate at the base, leathery, venation slightly prominent, petiole short and robust. Flowers are small, white or pinkish in terminal panicles from 20 to 50 cm. The fruits are small and hairy, containing a single seed. Ecology The soils of ultramafic rocks, which are mining terrains, have been a refuge for many native plant species of New Caledonia because they are toxic and their mineral content is poorly suited to most foreign species of plants.Dossier > La flore de Nouv ...

Dracophyllum Verticillatum, Mont Dore
''Dracophyllum'' is a genus of plants belonging to the family Ericaceae, formerly Epacridaceae. There are 61 species in the genus, mostly shrubs, but also cushion plants and trees, found in New Zealand, Australia, Lord Howe Island and New Caledonia. The name ''Dracophyllum'', meaning dragon-leaf, refers to their strong outward similarity to the unrelated '' Dracaena'', sometimes known as dragon tree. Although dicotyledonous, they resemble primitive monocots with their slender leaves concentrated in clumps at the ends of the branches; they are sometimes called grass-trees. The height varies from one centimetre ('' D. minimum'') to about 12 metres ('' D. longifolium''). Species The following species are recognised by '' The Plant List'': *'' Dracophyllum acerosum'' Berggr. *''Dracophyllum adamsii'' Petrie *''Dracophyllum alticola'' Däniker *''Dracophyllum arboreum'' Cockayne * ''Dracophyllum'' × ''arcuatum'' W.R.B.Oliv. *''Dracophyllum balansae'' Virot *''Dracophyllum cosmelio ...
