TLDR
The reforestation with native species provided a seed bank with a greater diversity of native arboreal species than the eucalyptus plantation, and the similarity between the planted and natural forest should be enhanced over the time.Abstract:
The objective of this study was to evaluate qualitative and quantitatively the seed bank of two natural forest remainders, one Eucalyptus robusta plantation and three reforestation areas with native species, located in a riparian area of Mogi-Guacu River floodplain, in Luiz Antonio County (21°31´S and 47°55´W), Sao Paulo State, Brazil The evaluation was carried out in 12 plots of 10 x 10 m systematically distributed in each area Four subplots of 05 m x 05 m were randomly distributed in each plot Two subplots were used to evaluate the seed bank in the litter and two in the soil sample at the 0 - 5 cm depth The sampling was accomplished in September 2001 in the natural forest remainders and in the eucalyptus plantation and, in September 2002, in the reforested areas The soil and the litter were conditioned in plastic pots, and incubated with periodic irrigations for the seed germination during seven months, in two greenhouse environment conditions: one at 100% sunlight and the other, under a screen that provides a 70% sunlight reduction In the composition of all sample area seed banks, there was a predomination of pioneer species at the early successional stages The most important arboreal species were Aloysia virgata and Cecropia hololeuca The reforestation with native species provided a seed bank with a greater diversity of native arboreal species than the eucalyptus plantation The present study indicates that the similarity between the planted and natural forest should be enhanced over the timeread more

Can Eucalyptus invade native forest fragments close to commercial stands
TL;DR: In this paper, the authors assess whether eucalypts can invade native vegetation fragments in proximity to commercial stands, and what factors promote this invasive growth, and assess the number of seedlings of E. grandis and E. urophylla.

Ecological impacts of non-native tree species plantations are broad and heterogeneous: a review of Brazilian research
TL;DR: Forest management can help maintain biodiversity if it considers previous environmental conditions and integrates plantations with surrounding habitats, and ecological impacts of non-native tree plantations are considered.

Banco de sementes como indicador de restauração em sistemas agroflorestais multiestraficados no sudoeste de Matto Grosso do Sul, Brasil
TL;DR: The seed density of tree species increased according to the age of the areas, suggesting successional advancement of themultistrata agroforestry systems studied, similar to what occurs in forests in secondary successional stage, demonstrating its ability to restore degraded areas.

Ecology of Soil Seed Banks
TL;DR: In this article, the relationship of seed banks to vegetation dynamics and processes that influence inputs and losses from seed banks was examined. But the role and importance of seed bank in vegetable types were not discussed.

O Banco de sementes de um trecho de uma floresta Atlântica montana (São Paulo - Brasil)
TL;DR: The results found in the study site suggest that in the Atlantic montane forest soil seed bank can be important for the establishment of woody species, which form ecological groups involved in forest regeneration, following slash-and-burn.
