EVIDENCIA DE DIRECCIONALIDAD DEL PROCESO DE SUCESIÓN TEMPRANA DEL BOSQUE ALTOANDINO Manuel Lequerica Mauricio Bernal Pablo R. Stevenson Agrociencias rística diversidad distancia flo Bosque secundario distancia geográfica Los bosques secundarios han aumentado su exten - sión en las últimas décadas y han sido propuestos como elementos de conservación. El propósito de este estudio fue evaluar la composición vegetal y la diversidad en potreros y bosques en Granada, Cun - dinamarca (Colombia), para comprobar si los pro - cesos sucesionales demuestran direccionalidad. Se ubicaron seis parcelas de 0.1 Ha del borde del bos - que hacia el potrero y hacia el bosque. Para cada parcela se determinó la estructura de la vegetación, diversidad, y composición florística. Se encontró que la diversidad de los bosques es significativa - mente superior a la de los potreros en etapas tem - pranas de sucesión. Por medio de ordenaciones el estado sucesional de cada una de las parcelas y se caracterizó, observando que la vegetación tiende a agruparse según su edad, evidencia de que la suce - sión es un proceso direccional. Dibujando perfiles de vegetación y calculando la densidad de plántulas a lo largo del gradiente bosque-potrero, se encon - tró que el reclutamiento de plántulas no es signifi - cativamente diferente entre el borde y el interior del bosque. Por último, se encontró una relación in - versamente proporcional entre distancias florísticas y geográficas de las parcelas, señalando la disconti - nuidad como una barrera a la sucesión del bosque. 2017 artículo científico 0120-0739 https://www.redalyc.org/articulo.oa?id=423949141006 es http://www.redalyc.org/revista.oa?id=4239 Colombia Forestal application/pdf Universidad Distrital Francisco José de Caldas Colombia Forestal (Colombia) Num.1 Vol.20
