The pre-fire vegetation had been analysed and mapped before its destruction. The structure of the community and the processes taking place in it (in terms of biomass, primary productivity, phenology, mineral nutrition and food value) had been examined. The redevelopment of the canopy was studied by the point-contact method along permanent line transects. This semi-quantitative study permits calculation of the relative frequency of each species and, from this, its cover. The growth form of each species and the stratification of the community are also indicated by this method. Permanent plots were also used to record changes in the vegetation, by means of a census of individuals and records of the development and growth strategy of each species. The plots were located in homogeneous areas, or on bare soil around seed parents in order to examine seed dispersal and seedling establishment. These two methods yielded detailed information on the nature of the secondary successions following fire in the heathlands of Brittany."

Problems in Heathland and Grassland Dynamics / John Miles in Vegetatio, vol. 46/47 (Année 1981)

Public [article]  inVegetatio > vol. 46/47 (Année 1981) . - pp. 61-74 Titre : Problems in Heathland and Grassland Dynamics Auteurs : John Miles (1941-....), Auteur Année de publication : 1981 Article en page(s) : pp. 61-74 Langues : Anglais (eng) Catégories : [habitats/milieux] 3 - Landes, fruticées et prairies [Thèmes] Pédologie (sol) Mots-clés : dynamique de la végétation  climat  microclimat  incendie  faune  pâturage  maladie  dispersion  compétition floristique  allélopathie  podzolisation Résumé : "A review of factors governing vegetation change in heathlands and grasslands is presented, with emphasis on soil factors. Climate, microclimate, fire, fauna, grazing by vertebrates, grazing by invertebrates, disease, dispersal, establishment, competition, allelopathy, stabilization, soil formation and podzolization are discussed with emphasis on inconsistencies and lacks in our present knowledge. Examples are mainly from NW European Calluna heath and related woodlands."
