Mosses are the first colonizers, soon forming a dense layer which locally prevents establishment of new species. Ten years later, the moss layer is still an important component of the regenerating heathland. After ten years the pattern of species distribution is mosaic-like with grassy patches (Agrostis), heath patches (Erica, Flex), and wood (Betula). Processes which may be involved in this successional pattern are discussed. They are found to be pluriform: various strategy types, types of response to disturbance and various succession models operate simultaneously."

Plant strategies and secondary succession on Brittany heathlands after severe fire / Bernard Clément in Journal of Vegetation Science, vol. 1, n°2 (Année 1990)

Public [article]  inJournal of Vegetation Science > vol. 1, n°2 (Année 1990) . - pp. 195-202 Titre : Plant strategies and secondary succession on Brittany heathlands after severe fire Type de document : texte imprimé Auteurs : Bernard Clément, Auteur ; Jean Touffet, Auteur Année de publication : 1990 Article en page(s) : pp. 195-202 Langues : Anglais (eng) Catégories : [ZG] BRETAGNE (53) [habitats/milieux] 3 - Landes, fruticées et prairies Mots-clés : suivi à long-terme  post-incendie  succession végétale Résumé : "Plant succession on heathlands subjected to major fire disturbance and humus burn in 1976 was studied over twelve years following burning. Life history strategies of principal heathland species are described with reference to concepts outlined by Grime (1979) and Whittaker & Goodman (1979). Heathlands and closely related communities are characterised by dominance of speciestolerant of physical stress (‘S’ strategists) whereas species which colonise disturbed sites are closer to rude-rals (‘R’ strategists). After severe burning three main successional patterns were identified. They depend on water and nutrient availability relative to temporal population dynamics. Recovery of heathland is often retarded due to monospecific dominance, e.g. of Polytrichum commune, Molinia caerulea and Betula pubescens. These patterns of secondary succession illustrate the inhibition model advanced by Connell & Slatyer (1977)."
