Direct seeding reduces costs, but it is not promising for restoring tropical seasonal forests

Abstract: A B S T R A C TDirect seeding is a potential technique to restore forests; however, further studies are needed before its application on a large scale. We carried out a field experiment in a deforested area in southern Brazil to test the technical and economic feasibility of a direct seeding system with high tree species diversity to restore the tropical seasonal forest. We also compared species performances and tested the effects of seed size and successional group on tree seedling emergence and development. … Show more

“…Low survival during both the germination and seedling phase are common in restoration projects and seed addition experiments; values of less than 20% probability of germination and survival until seedling phase are typical for tropical species (Holl 2002;Clark et al 2007;Rother et al 2013;Ceccon et al 2016;César et al 2016). Therefore, the choice of species with higher chances of survival when direct seeded is a key to restoration success (Souza and Engel 2018). We did not measure seed predation, which can also be a major cause of failure in direct seeding plantings (Rother et al 2013) -especially in forest environments-and potentially could explain high mortality of seeds in our experiment.…”

“…Muitos trabalhos têm mostrado uma correlação positiva entre o tamanho da semente e as probabilidades de emergência, sobrevivência e crescimento (VÁLIO, 2001;DALLING;HUBBELL, 2002;WESTOBY, 2004;ENGEL, 2018). Com maior quantidade de reservas nutricionais, durante o estabelecimento inicial, as sementes grandes possuem maior capacidade para suprir a plântula em períodos críticos (LEISHMAN et al, 2000;WESTOBY et al, 1996).…”

“…A técnica de semeadura tem tido maior utilização nos últimos anos (RUIZ-JAEN; AIDE, 2005;AGUIRRE et al, 2015;ENGEL, 2018). Essa técnica pode reduzir os custos em relação ao plantio de mudas porque reduz a necessidade de mão de obra, exclui a fase de viveiro e facilita o transporte do propágulo PARROTTA, 2001;CAVA et al, 2016).…”
