The floodplain forest in Tabasco, Mexico, a threatened plant community
The structure, composition and diversity of the floodplain forest (SMPC) of Bravaisia integerrima were studied in the two largest forest stands in Tabasco, Mexico: the Ecological Reserve Yu-Balcah (YCAH) with 271 ha, and State Park La Chontalpa (PECH) with 191 ha. In each forest stand 10 plots of 10...

| description | The structure, composition and diversity of the floodplain forest (SMPC) of Bravaisia integerrima were studied in the two largest forest stands in Tabasco, Mexico: the Ecological Reserve Yu-Balcah (YCAH) with 271 ha, and State Park La Chontalpa (PECH) with 191 ha. In each forest stand 10 plots of 1000 m2 were sampled. Tree individuals sampled were identified to species, and evaluated in three age categories, seedlings, saplings, and adults. The relationship between species richness and sampling effort was analyzed using Chao 2, ICE, Jacknife 1, Jacknife 2 and Bootstrap. The structural analysis was based on the importance value index. The diversity of species was evaluated, using the Margalef index (DMg), α de Fisher, Shannon-Wiener (H') and equity of Pielou J. The dominance indices of Berger-Parker (d) and Simpson (D) were also used. The total number of species was 76, belonging to 64 genera and 33 botanical families. The richest family was Leguminosae with 15 species. The basal area of the sites YCAH and PECH was 37.2 and 29.5 m2ha-1, respectively. Bravaisia integerrima was the most important tree species in all stands, with an Importance Index of 277. The value of the Shannon index was 2.0 in both sites. YCAH showed the best ecological condition. Six species present in the stands are considered as threatened in Mexico (NOM-059-SEMARNAT-2010). The current extent of the floodplain forest of Bravaisia in Tabasco State is 490 ha. The results suggest that the structure and composition of this forest has been affected by human activity. As a consequence, to guarantee the conservation of these remnants of SMPC in Tabasco, it is important to verify their legal situation and the application of management plans, designed to improve the productive activities of the rural communities that live around the stands. To succeed in this endeavor, it is necessary that governmental actors, academics, non-governmental organizations, and civil society work together. |

Se analizó la estructura, composición y diversidad arbórea de los dos rodales más importantes de selva mediana perennifolia de Bravaisia integerrima (SMPC) de Tabasco, México: el de la Reserva Ecológica Yu-Balcah (YCAH) con una superficie de 271 ha y el del Parque Estatal La Chontalpa (PECH) con 191 ha. En cada uno se levantaron 10 parcelas de muestreo de 1000 m2, cubriendo un área total de 2 ha. Se identificó y registró a las plantas arbóreas, diferenciando brinzales, plantas juveniles y adultos. Se aplicaron diversos índices para analizar el esfuerzo de muestreo, la diversidad de especies, la abundancia proporcional, la dominancia y la equidad. El análisis estructural se basó en el valor de importancia. La riqueza total fue 76 especies, pertenecientes a 64 géneros y 31 familias botánicas, de las que la mejor representada fue Leguminosae con 15 especies. El área basal de YCAH y PECH fue de 37.2 y 29.5 m2ha-1, respectivamente. Bravaisia integerrima fue el árbol con mayor valor de importancia en los dos rodales con un Índice correspondiente de 277. Ambos fragmentos tienen un valor del índice de Shannon de 2.0. El sitio con mejor condición ecológica fue YCAH. Se identificaron seis especies catalogadas en la NOM-059-SEMARNAT-2010. La SMPC presenta una cobertura actual en Tabasco de 490 ha. Los resultados sugieren que su estructura y composición se han visto afectados por la actividad antrópica en la región. Para garantizar la conservación de los remanentes de SMPC en el estado, es importante revisar y actualizar su situación legal y sus planes de manejo, así como generar alternativas sociales y productivas en las poblaciones cercanas. Para lograrlo se requiere de la participación de actores gubernamentales, académicos, organizaciones no gubernamentales, particulares y sociedad en conjunto.
