“…Dada a maior imprevisibilidade da germinação em condições de semeadura direta a pleno sol (Isernhagen 2010, Aguirre 2012) espécies menos abundantes e de distribuição mais restrita a locais isolados da ilha, como principalmente Jacquinia armillaris e Maytenus erythroxylon, tendem a ter menor disponibilidade de sementes e assim talvez devam ser inseridas na restauração através da produção de mudas e não da semeadura direta a fim de reduzir perdas das poucas sementes disponíveis.…”

-(Fructification phenology of native plant species and the forest restoration in Fernando de Noronha archipelago, Pernambuco State, Brazil). The annual pattern of fructification phenology of 23 native species of trees and bushes of Fernando de Noronha, Pernambuco State, Brazil was characterized with the aim of guiding the seed collection towards the implementation of a local restoration program. It was found that most species (74%) presented higher absolute frequencies of fructification during the rainy season (January to July) as opposed to 26% during the dry season, and the fructification lasted, on average, one month and a half. The Spearman correlation coefficient indicated a positive correlation between the studied phenophases and the precipitation. This kind of study is strategic for planning the seed collection and seedling production for restoration programs, especially in places where the process of Ecological Restoration is just beginning and still lacks information, such as Fernando de Noronha.

“…Entretanto, ainda não se sabe qual dessas técnicas seria a mais adequada para esse grupo vegetal. A semeadura direta, técnica ainda em desenvolvimento mesmo para espécies arbóreas, pode reduzir os custos da implantação do projeto de restauração (Engel & Parrotta 2001, Lamb et al 2005, Isernhagen 2010, Aguirre 2012), evitando a fase de produção da muda no viveiro e o seu transporte.…”

-(Diversity enhancement of a forest under restoration through direct seeding of lianas). The aim of this study was to analyze the feasibility of direct seeding of liana species in the understory of a restoring forest. Seeds of the species Phanera sp., Macfadyena unguis-cati (L.) A.H. Gentry, and Peltastes peltatus (Vell.) Woodson were submitted to germination tests considering the presence and absence of light and temperature cycle variation. These species were also planted under a canopy of four tree species in a 21-year-old restored forest in Iracemápolis, São Paulo State, Brazil. Macfadyena unguis-cati was the only species presenting a positive photoblastic characteristic, while the two other tested species were not affected by light or temperature cycle. In the understory, Peltastes peltatus did not emerge. In the two other species, seed germination was not influenced by the selected tree species. These results suggest that despite the low rate of emergence, it is possible to enhance the diversity of forest by restoring it through direct seeding of some liana species. Key words: forest restoration, germination, seasonal semideciduous forests, understorey RESUMO -(Enriquecimento de floresta em restauração por meio de semeadura direta de lianas). Este trabalho objetivou verificar a viabilidade da semeadura direta de lianas no sub-bosque de floresta plantada em restauração. Para isso, sementes das espécies Phanera sp., Macfadyena unguis-cati (L.) A.H. Gentry and Peltastes peltatus (Vell.) Woodson, de lianas foram submetidas a testes de germinação com e sem luz, e com e sem alternância de temperatura. Posteriormente, essas espécies foram semeadas sob a copa de quatro espécies arbóreas em uma Floresta Estacional Semidecidual em restauração no Município de Iracemápolis, SP, Brasil. Em laboratório, apenas Macfadyena unguis-cati apresentou característica de fotoblastismo positivo. As outras espécies não tiveram germinação limitada pela ausência de luz e alternância de temperatura. No sub-bosque, Peltastes peltatus não emergiu; as outras duas espécies não tiveram a emergência alterada em função das espécies arbóreas do dossel sob as quais foram semeadas. Esses resultados sugerem que, apesar da baixa taxa de emergência, é possível o enriquecimento de florestas em processo de restauração a partir da semeadura direta de algumas espécies de lianas.

The practice of using green manure for ecological restoration has grown so significantly that there is a shortage of seeds for purchase on the market. Nonetheless, there is very little literature available demonstrating the effects and benefits commonly cited for green manure for addressing important environmental filters, such as herbivory and invasive grasses. Our objective is to determine which spatial sowing arrangement including green manure promotes the lowest rates of herbivory on native species and decreases cover by invasive grasses in ecological restoration. We experimentally tested three sowing configurations of green manure intercropping with native species: T1 the lowest herbivoy rate for both native and green manure, mixture of native and green manure species in the same row, T2, alternating rows of green manure and native species, and T3, rows of native species intercropped with a 2 m wide strip of green manure. We found that (1) green manure species experience greater damage from herbivory than do native species, with average values ranging from 1.8 times higher values in green manure than natives in T1, 2.9 times in T2, and 2.7 times in T3 (when sown in rows and in broader strips, green manure and native species attract more herbivorous insects than if they were sown together [muvuca]); and (2) when green manure and native species are planted mixed in the same row they produce greater soil cover, and thus limit invasion by undesired species. The use of green manure has been identified as an alternative method for overcoming the environmental filters of herbivory and invasive grasses in restoration areas. Considering the demand for information that supports the use of green manure for purposes of ecological restoration, the novel results of the present study fill a void and should prove to be of great interest to researchers and practitioners. In addition, the presented results provide information on efficient and low-cost restoration techniques that are necessary for the activity to gain scale, enabling countries to meet the large restoration targets.
