Factors Limiting Tropical Rain Forest Regeneration in Abandoned Pasture: Seed Rain, Seed Germination, Microclimate, and Soil
Vegetation, seed rain, seed germination, microclimate, and soil physical and chemical parameters were measured in a recently abandoned pasture and adjacent primary rain forest in southern Costa Rica. The goal of this study was to assess the importance of these factors in limiting forest regeneration in abandoned pastures. Seed rain of animal dispersed species decreased dramatically in the pastu...
متن کاملSeed rain, soil seed bank, seed loss and regeneration of Castanopsis fargesii (Fagaceae) in a subtropical evergreen broad-leaved forest
Understanding the seed rain and seed loss dynamics in the natural condition has important significance for revealing the natural regeneration mechanisms. We conducted a 3-year field observation on seed rain, seed loss and natural regeneration of Castanopsis fargesii Franch., a dominant tree species in evergreen broad-leaved forests in Dujiangyan, southwestern China. The results showed that: (1)...
متن کاملEstimating soil seed bank characteristics in Ponderosa Pine Forests using vegetation and forest-floor data
Soil seed banks are important for vegetation management because they contain propagules of species that may be considered desirable or undesirable for site colonization after management and disturbance events. Knowledge of seed bank size and composition before planning management activities facilitates proactive management by providing early alerts of exotic species presence and of abilities of...
متن کاملThe soil seed bank during Atlantic Forest regeneration in Southeast Brazil.
A survey was conducted to determine the density and species composition of viable seeds buried in four stands of a tropical montane forest at Parque Estadual Intervales, Brazil. The objective was to understand: (1) how numbers and composition of the soil seed bank change as the forest regrows, and (2) how such changes affect the species available for regeneration if forests of different ages ar...
متن کاملThe potential for vegetation restoration from soil seed bank in abandoned croplands on the hilly-gullied Loess Plateau, China
The results of field survey, germination and correspondence analysis showed that the soil seed banks density ranged from 900 to 6,467 seeds m at 0-5 cm depth and 117 to 2,467 seeds m at 5-10 cm depth, with species richness of 7-14. Early successional species dominated the soil seed bank, while later successional species occurred only at low density. The similarity between soil seed bank and sta...
