This paper discusses the representation of semi-natural vegetation, drawing on examples of heathland vegetation that lie along continua. Tow alternative approaches to the representation of heathland vegetation are examined, both of which aim
Detrended correspondence analysis of heathland vegetation: the identification of runoff contributing areas
Detrended correspondence analysis is applied to information on vegetation composition for the heathland zone of a New Forest catchment. A map of runoff contributing areas is constructed from a soil moisture related gradient in the vegetation data
Heathland is a vegetal formation bound to all coastal zones of Western Europe, from Portugal to Bretagne. The type of soil, sandy, generally acid, and the presence of winds blowing from the Atlantic ocean, with middle or elevated rainfall, prevent
the development of a forest. Characteristics elements are Ericaceae, Leguminosae and Graminoid plants. Among plants several degrees of adaptation to heathland environment can be recognized, which point to a remote origin of both species and ecosystem, which has
This paper explores the soil nutrient pools of 14 young dry grasslands and compares them to the nutrient pools on heathlands, forested and agricultural land. On 2 sites, the plant species composition is compared to characteristic species for the EU

diversity. The fire-prone ecosystems of mediterranean-type shrublands and heathlands, savannas and grasslands, and boreal and other coniferous forests are the main geographic focus of the paper.
To that purpose 3 representative soil profiles on phyllite and sandstone under sclerophyllous oak, pine and heathland were selected. Without attempting a budget study for the entire forested area, the hypothesis that decomposing organic matter
