“…Thus its small seeds, which are very attractive to a series of birds that fly great distances, present a wider distribution pattern. A similar pattern was detected for Trema orientalis (L.) Blume in secondary forest in Thailand, where the seedling density increased with distance from the source, and viable seeds were found up to 175 m from the source (Cheke et al, 1979).…”

The floristic composition and structure of vegetation in natural regeneration were studied in a degraded area in Matupá County, Mato Grosso State, Brazil, originally occupied by Tropical Rain Forest. Three plots were used in the shape of a 20 m Â 160 m transect, divided into 10 m Â 20 m sub-plots, placed parallel to a remnant fragment. Transect 1 was 0-20 m from the fragment; Transect 2, 20-40 m, and Transect 3, 40-60 m from the forest fragment. The total height and diameter at soil height of all the shrubs and tree individuals (height ! 0:50 m) were measured to the 5, 13 and 18 months after the area had been systematized and abandoned. Floristic and structural alterations occurred in space and time. The number of individuals, species, families and diversity increased during the time interval studied and decreased with distance from the remnant fragment. These floristic and structural alterations in the community as a whole and in the populations of the most important species, Trema micrantha (L.) Blume and Schizolobium amazonicum Huber ex Ducke, showed the tendency of a succession model by facilitation, where these pioneers would be improving the ecological conditions and thus easing the regeneration of late species. The conservation of the forest fragment in the surroundings was essential for the natural regeneration process of the forest in the degraded area. #

“…In our particular study system, A. dumosa, D. suffructicos, R. cinerea, and F. fragrans have been commonly found on soil impoverished after decades of exhaustive agricultural use (Corlett, 1991a;Sim et al, 1992). In addition, a final piece of evidence that supports the conjecture that our secondary forest soils were likely impoverished is the striking lack of fast-growing Macaranga trees, which are usually one of the first trees to establish in Southeast Asian secondary forests (Brearley et al, 2004;Cheke et al, 1979;Shono et al, 2006). Macaranga are also more diverse and abundant in nutrient-rich secondary forest (Wyatt-Smith, 1963), but almost absent on forest with impoverished soil (Sim et al, 1992).…”

“…This is of relevance to questions concerning the role of seed in determining initial floristic composition following disturbance, and the migration of seed into vegetation undergoing change (Hill & Stevens 1981;Swaine & Hall 1983;Hopkins & Graham 1984;Graham & Hutchings 1988). For instance, many studies have demonstrated that seeds of secondary species persist beneath stable vegetation (Cheke et al 1979;Enright 1985;Gransl/om 1988), and initiate succession following disturbance. Large scale migration from an adjacent source was, however, suggested by Strickler & Edgerton (1976) and Archibold (1979).…”

Soil seed banks at 21 sites covered with poor quality pasture, bracken femland, scrubland of broom or gorse, and various forest types, were examined by germinating seed in soil samples. At most sites the composition of upper and lower soil layers was similar. Persistent, deeply buried seed banks of Cytisus scoparius, Ulex europaeus, and more rarely Sophora microphylla, were discovered at seven sites, four of which lacked that particular species in the above-ground vegetation, and are thus considered to be of a former vegetation type. Forest sites tended to have more seeds and more species represented in the soil seed bank. Although an average of only 35% of the species in the seed bank were represented above ground at the sampling point, this rose to 60% within 5 m, and 72% within 10 m of that point. Those species further away were mostly widespread pasture weeds, even within forest sites, and are interpreted as being recently dispersed and transient. Large quantities of Juncus spp. in some sites are believed to be transported by water movement through the soil. Some species, including certain site dominants, were poorly or never represented in the soil seed bank. It is considered that the seed bank has an important role in establishing the initial floristic composition following disturbance. However, differential seedling survival, resprouting, and competition probably help in maintaining the predisturbance vegetation at non-forest sites. Where forest is disturbed, especially by burning, there is the potential for a completely different vegetation to develop from the seed bank.
