| description | Background and Aims: In an experiment initiated in 2006 in an induced pasture, within a landscape dominated by tropical rainforest, in Los Tuxtlas, Veracruz, 24 fenced plots with three restoration treatments were established. Our objective was to determine with camera trapping, which species of medium or large terrestrial mammals (≥1 kg in weight), and with what frequency, visited the plots 12 years after the establishment of the experiment.Methods: Camera traps were used in 18 of the 24 plots. Two censuses were carried out, one in the rainy season of 2018 and the other in the dry season of 2019. The number of species and the independent photographic records of each one were determined for each treatment (plots excluded from cattle: a) with no addition of plants -natural succession-; with tree plantations, b) dispersed by wind, and c) dispersed by animals) and each sampling season.Key results: The total sampling effort was 290 camera trap days. For the rainy season, 12 photographs and four videos of opossum (Didelphis spp.), nine-banded armadillo (Dasypus novemcinctus) and Mexican agouti (Dasyprocta mexicana) were obtained. For the dry season, the armadillo was recorded in 10 photographs and five videos. There were few records of medium-sized mammals, compared to photo trapping in conserved forest in the area and only in seven of the 18 sampled plots. Overall, there were more records in plantations than in natural succession, and this was more evident in the rainy season.Conclusions: The response of medium-sized terrestrial mammals to restoration seems to be slower than recorded for other faunal groups (e.g., bats). To assess the recovery of ecological functionality that includes the ecological roles played by medium-sized mammals in this experiment, monitoring effort should be continued and expanded. |

Antecedentes y Objetivos: En un experimento de restauración iniciado en 2006 en un pastizal inducido, dentro de un paisaje dominado por selva tropical lluviosa en Los Tuxtlas, Veracruz, se establecieron 24 parcelas cercadas, con tres tratamientos de restauración. Nuestro objetivo fue determinar, mediante fototrampeo, cuáles especies de mamíferos terrestres medianos o grandes (≥1 kg de peso) y con qué frecuencia visitaban las parcelas, a 12 años de iniciado el experimento.Métodos: Se utilizaron cámaras-trampa, en 18 de las 24 parcelas. Se hicieron dos muestreos, uno en el periodo lluvioso de 2018 y otro en el seco de 2019. Se determinó el número de especies y de registros fotográficos independientes para cada una, en cada tratamiento (parcelas excluidas del forrajeo del ganado: a) sin adición de plantas -sucesión natural-; con plantación de árboles, b) dispersados por viento y c) dispersados por animales) y temporada de muestreo.Resultados clave: El esfuerzo total de muestreo fue de 290 días/cámara-trampa. En el periodo lluvioso se obtuvieron 12 fotografías y cuatro vídeos de tlacuache (Didelphis spp.), armadillo (Dasypus novemcinctus) y guaqueque mexicano (Dasyprocta mexicana). En la época seca se registró al armadillo en 10 fotografías y cinco vídeos. Hubo pocos registros de mamíferos medianos, en comparación con fototrampeos en la selva conservada de la zona, y en solo siete de las 18 parcelas muestreadas. En general, hubo más registros en parcelas con cualquier tipo de plantación que en las de sucesión natural y esto fue más evidente en la época de lluvias. Conclusiones: La respuesta de los mamíferos medianos terrestres a la restauración parece ser más lenta que la registrada para otros grupos faunísticos (p. ej., murciélagos). Para evaluar la recuperación de la funcionalidad ecológica que incluye los roles ecológicos que desempeñan los mamíferos medianos en este experimento, se debe continuar y ampliar el esfuerzo de monitoreo.
