 +**Natural regeneration and seedling diversity in a coastal plain transition ecosystem - hillside**
 +**Abstract:​** The seedling community of coastal plains of Caraguatatuba county was studied in a
 +fragment of 50 acres of Forest Transition Restinga - Hill. The study area has been
 +described by means of 40 sets of three plots of 1m x1m totaling an area of 120m2,
 +with 23 sets were flooded condition and 17 in non-flooded conditions (drought). We
 +obtained canopy opening with the help of Densiometer. In total 507 seedlings were
 +identified, representing an average of 4.23 seedlings per m2. It was possible to
 +observe a high richness, with 82 different species. The most abundant species were
 +//​Calypthrantes sp// (107), //Myrta sp1// (82) and //Annona cf reticulata cf// (19). The family
 +Myrtaceae showed the highest species richness, totaling 18 species. The flooded
 +plots had on average 9.99 seedlings per 3m 2 and droughts 15.69 per 3m 2. The
 +average number of species in the wetlands was 3.69 species per 3m 2 and in the dry
 +plots was 6.11 seedlings per 3m 2. The predictions of this study were that the
 +wetlands should contain fewer species and lower species richness compared to
 +areas not flooded. For canopy opening was expected that more open areas possess
 +greater number of seedlings and greater species richness. However after
 +randomization of data was not possible to observe that wetlands had less wealth and
 +fewer species (p = .33). Increasing the percentage of canopy openness did not
 +significantly affect the number of seedlings (p = 0.23) or species richness (p = .44).
 +Thus, the results indicate that environmental variables are not sufficient to explain the
 +observed variation in abundance and species richness of seedlings in this
 +ecosystem. However other factors may be limiting for seedling establishment. Among
 +the possible factors, the human disturbance area for removal of palm (Euterpe
 +edulis), the large number of paths traced in the region (trampling seedlings) and
 +competition from herbaceous plants deserve more detailed studies in the future.

 +**Survey of Seedling Production of Restinga Species in Nurseries State of São Paulo: Implications for ecological restoration**
 +**Resumo:** To be viable to carry out restoration projects following the scientific statements and
 +legislation is essential that there is availability of seedlings in nurseries with high species and
 +genetic diversity. In order to evaluate the current availability of seedlings, production capacity
 +and the main constraints to the production of a high diversity of restinga (white sand coastal
 +vegetation) species, a study was conducted with nurseries producing seedlings of restinga
 +species in the state of São Paulo. In total, 122 nurseries and 41 counties were contacted,
 +resulting in only six nurseries producing seedlings from areas of restinga. The definition of
 +the profile of resting seedlings production in these six nurseries was done through
 +questionnaires technical and administrative. Among the main results of this survey, we can
 +highlight the small number of seedlings of restinga species produced by the north coast
 +nurseries, the difficulties in obtaining seeds mainly related to the process of seed collection,
 +the disarticulation of the sectors involved in the production of seedlings of restinga species,
 +the tiny share of the municipalities in seedling production and the perception of the producers
 +of changes in the fruit phenology of the restinga species in their collection areas. This study
 +highlights the current shortage of seedling of restinga species and should be useful as a tool to
 +reveal the nurseries working in this ecosystem, and to improve the contact between them and
 +the restoration planning groups.
