Tree plantation is the most used technique for ecological restoration, although passive restoration requires a lower investment of resources. This research aimed to compare the composition and structure of the community of regenerant plants in areas under restoration through Assisted Natural Regeneration and mixed native Tree Planting, in the same area. We randomly placed 12 plots of 100 m² each and sampled all the regenerating individuals found within them. We compared both restoration methods regarding growth pattern, dispersal syndromes, and successional groups. In both methodologies, trees and shrubs were the most abundant growth forms. The pioneer successional class was the most abundant in number of individuals for both treatments. We concluded that the two restoration methods allowed the regeneration of native species. We propose that Assisted Natural Regeneration is a viable restoration strategy, capable of boosting the initial processes of the community, especially in a matrix surrounded by remaining forests.
Direct seeding is a promising and low-cost restoration technique. To avoid wasting seeds, the selection of species with high field performance in their establishment can increase efficiency. We aimed to identify groups of forest species with the ability for direct seeding in a seasonal forest, investigate taxonomic similarity effects on species behavior regarding seeds’ and seedlings’ early functional traits, and classify species based on their probability of success by direct seeding. A planting system of 38 seasonal forest species was implemented at a density of 250,000 seeds ha−1. The emergence was monitored over 720 days, and all individuals were identified, tagged, counted, and measured for height (H) and diameter at collar height (DCH). We evaluated early traits of seed vigor (field seed emergence), seedling performance, probability of success, and species autoecology. Species’ ability for direct seeding was more related to the level of species phylogeny than to their family. Pioneer and non-pioneer species demonstrated similar abilities for direct seeding associated with field emergence, seedling abundance, and persistence. Field seed emergence traits influenced species’ ability for direct seeding more than seedling survival or growth. Species’ ability for direct seeding was related to early seed vigor traits expressed by field seed emergence and was independent of their density.
The homegardens result from collective learning and fulfill environmental services, contributing to the agrobiodiversity conservation and food security. The present study analyzed whether legal mechanisms incorporate concepts on environmental services and if legal frameworks in the state of São Paulo include homegardens as a feasible system for restoration of legal reserve (RL) area. Revisions of Law nº 12.651/2012 and resolutions SMA nº 44/2008 and SMA nº 32/2014 were carried out. For each attribute regarding the environmental services, grades from zero (absent) to two (explicitly described) were assigned. In the legal frameworks, the concepts concerning production, regulation and support were present, with the absence of cultural ones. For the adoption of homegardes as a viable system for restoration in legal reserve area, precepts should be changed regarding the presence of exotic species, management and monitoring practices required in legal frameworks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
