| description | Tropical rainforests have been a valuable source of resources for human kind. However, this ecosystem is disappearing at an alarming rate, with only isolated fragments remaining in inaccessible zones and showing high probability of disappearing. The aim of this study was to identify tropical rainforest plant species with potential for human use in the central region of Veracruz, Mexico. A floristic inventory was compiled of rainforest fragments and secondary vegetation using the plotting method. The total area sampled was 5600 m2. Using the equation Clench model, the proportion of species inventoried was assessed. This was 85% (tq = 0.85) for the rainforest and 90% (tq = 0.9) for the secondary vegetation. A total of 338 species, 210 genera and 89 families were recorded. Using semi-structured interviews with locals, a list of useful plants was drawn up and it was found that people recognized and used 47% of the species inventoried. Additionally, contingency tables and the Spearman correlation test were performed to determine the differences in knowledge and use of the vegetation among villages, as well as in the gender and age group of the respondents. Nevertheless, we found no significant differences (P>0.05). The use value (UV) was calculated to analyze the use of flora. in order to assess the relationship between the UV and their ecological importance, the index of adjusted ecological importance value (AEIV) was obtained. We detected that the most used species are not necessarily those of greater ecological importance. The potentially useful flora was defined based on a literature research, in situinterviews, as well as on their visual and morphological characteristics. According to the data, more than 50% of the inventoried species are potentially useful, mainly as ornamental and medicinal ones, and they provide new economic alternatives for the local people with a minimum impact on the rainforest. |

Las selvas tropicales perennifolias representan una fuente de recursos valiosos para la humanidad. Sin embargo, están desapareciendo a una velocidad alarmante, quedando solo fragmentos aislados localizados en zonas de difícil acceso y próximos a desaparecer. El objetivo de este estudio fue identificar las especies vegetales de la selva mediana perennifolia con características potenciales de uso en la región central del estado de Veracruz, México. Para ello se realizó un levantamiento florístico en fragmentos de selva y vegetación secundaria usando el método de muestreo por cuadros. El área total muestreada fue de 5600 m2. Mediante la ecuación del modelo de Clench, se evaluó la proporción de especies inventariadas, la cual fue de 80% (tq = 0.8) para la selva y 90% (tq = 0.9) para la vegetación secundaria. Se registró un total de 338 especies, 210 géneros y 89 familias. A través de entrevistas semiestructuradas, se generó un listado de las plantas útiles y se encontró que la población conoce y usa 47% de estas especies. Se realizaron tablas de contingencia y un análisis de correlación de Spearman para determinar las diferencias entre el conocimiento y uso de la vegetación en las localidades, así como entre el género y el grupo de edad de los entrevistados. Sin embargo, no se hallaron diferencias significativas (P > 0.05). Para analizar el uso de la flora, se calculó el valor de uso (UV) y para evaluar la relación entre el valor de uso de las especies y su importancia ecológica, se obtuvo el índice ajustado de valor de importancia ecológica (AEIV). Con ello se detectó que las plantas más usadas no son necesariamente las de mayor importancia ecológica. La flora potencialmente útil fue definida con base en la revisión bibliográfica, las entrevistas y a sus características visuales y morfológicas. De acuerdo con los datos obtenidos, más de 50% de las especies inventariadas poseen este valor, principalmente como ornamentales y medicinales, y proporcionan nuevas alternativas económicas para los pobladores locales con un mínimo de destrucción de la selva tropical.
