Floristic survey in an Atlantic Forest remnant in the Recôncavo da Bahia, Bahia State, Brazil

Abstract

This work presents a list of the Angiosperms that occurs in a fragment of the Atlantic Forest, Recôncavo da Bahia region. The present study was carried out in the Serra da Copioba in the municipality of São Felipe, Bahia State, Brazil. Botanical expeditions were carried out in the studied area between the years 2016 and 2017. The collections were performed in trails throughout the region of the Serra da Copioba. The specimens were housed in the Herbarium of the Recôncavo da Bahia (HURB). We found 306 species. The rates of endemism registered by this study are 20.46% for species occurring exclusively in the Atlantic Forest and 4.25% are endemic to Bahia State. The good indexes of endemism added to the exclusive occurrence of plants make the Copioba Mountain an important remnant of the Atlantic Forest of the region.

Characterization of soils cultivated with cassava under different managements

“…The climate varies between humid and dry sub-humid with average annual temperature of 23.8 °C and average annual precipitation of 800 to 1100 mm, and the predominant soils are Oxisols (Moreira et al, 2020). During soil collection the average temperature was 24.5 ºC, with an relative air humidity of 79% and precipitation of 0.08 mm, data that were monitored by a meteorological station in a neighboring municipality by the National Institute of Meteorology (INMET, 2018).…”
