  rdf:value "Poblaciones de árboles forestales de especies serales o clímax que crecen solas o asociadas a otras especies de árboles. Generalmente ya han alcanzado su edad de madurez, definida por la culminación del incremento promedio anual, y suelen presentar características de descomposición, entre las que se incluyen: un bajo ritmo de crecimiento, árboles muertos y a punto de morir, tocones y material leñoso caído. Suelen caracterizarse por tener árboles de gran diámetro en relación con el potencial de la especie y del lugar, copas con múltiples capas, árboles de diversos diámetros y vegetación de sotobosque. Sus cualidades específicas dependen principalmente de las asociaciones vegetales y del tipo de cubierta forestal."@es, "Stands of forest trees of either seral or climax species growing singly or in association with other tree species. The stands are usually well past the age of maturity as defined by the culmination of mean annual increment and often exhibit characteristics of decadence. These characteristics may include, but are not limited to: low growth rates, dead and dying trees, snags, and down woody material. The stands are usually characterized by large diameter trees relative to species and site potential, multi-layered canopies, a range in tree diameter sizes, and the presence of understory vegetation. The specific attributes of an old-growth stand are primarily dependent on plant associations and forest cover type."@en ;
