| description | Structure, composition, diversity, environmental relationships, and conservation status of a cloud forest with Acer saccharum subsp. skutchii (sugar maple) are described in a recently found locality at Coahuayutla de José María Izazaga municipality, state of Guerrero, Mexico. Woody individuals ≥1 cm dbh in 10 m/radius circular plots and seedlings and saplings heights of sugar maple in 5.6 m/radius circular plots were recorded. The relative ecological importance of each species was expressed in an importance value. Non-metric Multidimensional Scaling (NMDS) ordination technique was used to explore the species correlations with edaphic, geographic coordinates, elevation, and canopy gaps variables. 43 woody species in 0.126 ha were recorded. The families with most species were Asteraceae and Fagaceae. The diametric distribution of woody species showed an inverted “J” shape, indicating successful regeneration. Sugar maple is co-dominant with Carpinus caroliniana and Quercus uxoris. Most correlations between presence-absence of trees, including Acer saccharum subsp. skutchii, were with soil characteristics in the population of Guerrero and all maple localities in Mexico and Guatemala. 30% of the reported species are included in some risk category. The fire regime in the zone is a major threat for the persistence of the studied species. |

Se describe la estructura, composición, diversidad, relaciones ambientales y conservación de un bosque mesófilo con Acer saccharum subsp. skutchii (arce azucarero) recientemente encontrado en el municipio de Coahuayutla de José María Izazaga, Guerrero. Se registraron los individuos leñosos con ≥1 cm dap en parcelas circulares de 10 m de radio, y la altura de plántulas y plantas juveniles del arce azucarero en parcelas de 5.6 m de radio. Para cada especie se obtuvo su valor de importancia. Se utilizó la técnica de ordenación Escalar Multidimensional No-métrica (NMDS) para explorar sus correlaciones con variables edafológicas, coordenadas geográficas, de elevación y apertura de claros. Se registraron 43 especies de plantas leñosas en una superficie de 0.126 ha. Las familias mejor representadas fueron Asteraceae y Fagaceae. La distribución diamétrica de las plantas leñosas mostró una forma de “J” invertida, indicando regeneración exitosa. El arce azucarero fue codominante en el dosel con Carpinus caroliniana y Quercus uxoris. Tanto en la población de Guerrero, como en las otras cinco localidades donde habita el árbol en México y Guatemala, la mayoría de las correlaciones encontradas entre la presencia y ausencia de árboles, incluyendo Acer saccharum subsp. skutchii, y los factores ambientales se refirieron a las características de suelo. De las especies registradas en el estudio, 30% están incluidas en alguna categoría de riesgo. El régimen de incendios en la zona pone en peligro la persistencia de este árbol en el sitio de estudio.
