Analysis of the natural regeneration of the white mangrove (Laguncu-laria racemosa (L.) C.F. Gaertn. with dasometric variables during the drought season

Resumen

Objective: To analyze the natural regeneration of the white mangrove (Laguncularia racemosa L.) with dasometric variables, during the drought season, in the ejido La Solución Somos Todos in Paraíso, Tabasco, Mexico.

Design/Methodology/Approach: The structural variables of white mangrove —diameter at breast height (DBH), height, and canopy diameter— were measured in three sampling plots. A statistical analysis was performed with the resulting data and the mean data were determined for the three sampling plots.

Results: The following data were recorded for each sampling plot: DBH (0.34, 0.37, and 0.42 cm), height (134, 128, and 158 cm), and canopy (44.18, 38.56, and 39.83 cm).

Study Limitations/Implications: In the dry season, erosion can expose rocky and sandy substrates that are not suitable for mangrove growth.

Findings/Conclusions: The white mangrove —which undergoes its brinzal (seedling) stage during the dry season— recorded statistically significant differences in growth between sampling plots using the dasometric variables (DBH, height, and canopy diameter).
