Vegetation dynamics in a coastal grassland of Hawaii, permanent monitoring sites. The two sites are equipped with experimental exclosures against feral goats. The sites were monitored annually for a decade (1971–80) for changes in cover by species. The vegetation changes reported relate to both inside- and outside-exclosure developments..Four dynamic

Dynamics of some Western Australian ligneous formations with special reference to the invasion of eency and type of fire have been a major disturbance to the dynamics of natural vegetation, and this disturbance has allowed rapid spread of exotics, particularly in urban and semi-rural regions. Less obvious disturbances include changes in nutrient levels and hydrological regimes, which also allow e

Pattern development of the vegetation during colonization of a burnt heathland in Brittany (France)lopment of the vegetation was followed using permanent plots. The results presented concern the three first years: 1977, 1978 and 1979. One year after burning the area was sampled along a 128 × 1 m transect (samples in 50 × 50 cm contiguous quadrats) to situate this area in relation to its general v
