Abstract

Mangrove extension has been suffering a significant reduction over the years and the main threats to this ecosystem are deforestation for coal production, land conversion for aquaculture, construction of civil works, highways, and other uses. Due to these negative environmental impacts, many studies have been conducted with the purpose of rehabilitating these ecosystems. The aim of this study is to relate the survival and growth of Avicennia germinans (L.) Stearn, Rhizophora mangle L. and Laguncularia racemosa (L.) Gaertn. F. seedlings with the physico-chemical properties of degraded soils. The experiment was conducted on PA-458 highway, km 17, in the municipality of Bragança, Pará, Brazil. Experimental design consisted in random blocks with 3 treatments (3 species) and 6 replicates. Each plot consisted of 20 plants with spacing of 1.0 m between plants and rows. Data were analyzed using the PRIMER v6 software. Principal Component Analysis (PCA) was applied to abiotic variables and the relationship between biotic and abiotic data was established using the BIOENV procedure, which calculated Spearman’s correlation coefficient. Our results showed that the physico-chemical conditions of the soil associated to low rainfall during dry season in the region are limiting factors, and negatively influenced survival and growth of species, thus explaining why seedling mortality increased throughout the year in the experimental area.
