Development of tree species in the Bosque Dendrológico of IF Baiano, Teixeira de Freitas campus, Bahia

Abstract

This study aimed to evaluate the development of 42 Atlantic Forest tree species established in a mixed planting within the Bosque Dendrológico of IF Baiano, Teixeira de Freitas campus (Bahia, Brazil). The seedlings were planted in 2018 in an area previously used for sugarcane cultivation, and tree measurements were conducted seven years after planting. The 1,800 m² experimental area received prior soil preparation, organic fertilization, and hydrogel application. The spacing between seedlings was 3 x 3 meters, totaling 168 individuals, comprising four of each species. In 2025, the base diameter and total height of the surviving trees were measured. The results showed variation in growth among species. Five species stood out for their higher average values of base diameter and total height: Enterolobium contortisiliquum, Inga edulis, Trema micrantha, Guazuma crinita, and Guazuma ulmifolia. These species, generally classified as pioneers, may be recommended for forest restoration projects in similar edaphoclimatic conditions. Some species showed total mortality, indicating greater ecological requirements. The findings highlight the importance of experimental plantings in technical supporting decisions in restoration programs and as a didactic tool in agricultural science courses. Continued monitoring of the grove will expand knowledge on the silvicultural and ecological performance of native Atlantic Forest species.
