TAMAÑO DE FRAGMENTOS FORESTALES EN EL BOSQUE DE PINO-ENCINO, SIERRA DE QUILA, JALISCO

Abstract

Se evaluó la riqueza, la composición y la abundancia de especies de árboles en función del tamaño de fragmentos del bosque de pino-encino del área natural protegida Sierra de Quila. Se seleccionaron dos tipos de fragmento (10-50 ha y >50 ha) en bosque cerrado (BC, cobertura de copa >40%) y bosque abierto (BA, <40%). Se hizo el inventario del arbolado (DAP ≥ 7 cm) en 76 sitios concéntricos (0.05 ha), distribuidos en una red sistemática de muestreo. En los BA se registraron de 11 a 17 especies y en los BC de 16 a 24. Aun cuando la diferencia en riqueza de especies no fue significativa (p>0.06) entre tipos de cobertura y tamaño de fragmentos, si existe una mayor uniformidad en la abundancia en los BA. Destacan seis taxa que no se observaron en ninguna de las condiciones menores a 50 ha: Alnus acuminata, Clethra hartwegii, Pinus herrerae, Quercus candicans, Quercus excelsa y Tilia mexicana. Mediante técnicas de ordenación se identificó que en ambos tamaños de fragmentos las variables altitud, tipo de suelo y abundancia de hojosas correlacionaron de forma significativa con las asociaciones de especies arbóreas. La exposición y la abundancia de pinos fueron relevantes en los BA; mientras que, el diámetro promedio y la densidad de árboles se correlacionaron con los BC. Los patrones de distribución son elementos clave para la conservación integral del paisaje y de las diferentes condiciones en las que se desarrollan las coberturas forestales.
