skeletal soil

It forms pure patches on rocky habitats with skeletal soils.

One example is that skeletal soils cannot hold the 200 mm of rainfall assumed as a limit for the model.

Sometimes a shrub in the poorer skeletal soils.

Open forests are confined to areas of infertile skeletal soils with more than 600 mm of annual rainfall.

It grows on skeletal soils on steep north-facing slopes at an altitude of about 600 metres above sea level.

Orthents - shallow or "skeletal soils".

They occur on the poorest soils in high rainfall areas, and are well suited to skeletal soils and frequent fires.

Soils of all textures, including skeletal soils and soils derived from most parent materials are colonized.

They are often referred to as skeletal soils or, in the FAO soil classification, as lithosols.

Bacteria and fungi are the most important groups in the breakdown of organic detritus left by primary producing plants such as skeletal soil, moss and algae.

Areas favoured by the grasswrens are characterised by laterites, shallow loams and clays, and skeletal soils.

These rocks provide very nutrient poor skeletal soil and the main nutrient resource is accumulated through from degrading vegetation in humus and shallow peats.

The dominant species in these communities are Gymnoschoenus sphaerocephalus (buttongrass) in muck peat and Lepidosperma filiforme on more skeletal soils.

In Australia vast areas formerly covered in rainforest have become so dry that oxisols have formed a hard ironstone cover upon which only skeletal soils can form.

Blanket peat covers 90% of the catchment with skeletal soils towards the fell tops and small areas of limestone soils and alluvial soils.

The skeletal soils in the abandoned quarry at the southwestern end of the site support the largest population of dark-red helleborine, Epipactis atrorubens, in County Durham.

Geochemical exploration strategies over much of the Mt Isa Block are relatively simple due to the extensive outcrop of unweathered or partially weathered bedrock and skeletal soils.

This cycad has a main distribution in sparse Eucalyptus savanna on skeletal soils over outcrops of rhyolite or basalt west of the Atherton Tableland in north-east Queensland.

Open grassland and heath occur in such areas although heath is more usually found in high rocky areas where extreme cold, exposure to wind and skeletal soils on rock limit the growth of trees.

On O'Connor Ridge there is dry sclerophyll forest of the Eucalyptus macrorhyncha (red stringybark) / E. rossii (scribbly gum) on the skeletal soils of the hilltops and slopes.

Internationally, Regosols correlate with soil taxa that are marked by incipient soil formation such as Entisols in the USDA soil taxonomy or skeletal soils in the Australian soil classification.

Where a skeletal soil layer has developed on the quarry floor and spoil heaps, patches of grassland occur, with species characteristic of base-rich soils, such as quaking grass, Briza media, and limestone bedstraw, Galium sterneri.

The island's geology consists of a 'granite base and thin calcarenite mantle' which is 'likely to be fragmented into jagged rocks and shingles, with a sandy, skeletal soil filling depressions' in areas that are 'beyond the reach of storm waves'.

Further inland, heaths occur in other formations, particularly in the Open-forest and Woodland - shrubland subformation, on exposed or seasonally wet and poorly drained areas and on thin skeletal soils of the Triassic sandstone and granite areas.
