Diagramas de manejo de densidad para renovales de roble, raulí y coigüe en Chile = Stocking management charts for roble, raulí and coigüe second growth forests in Chile
A total of 214 permanent and temporary plots from roble (Nothofagus obliqua ), raulí (N. alpina) and coigüe (N. dombeyi) pure and mixed second growth forests located between 37°30 and 42°00 south latitude in Chile were used to fit an average size-density model. This model was then modified to obta...

| description | A total of 214 permanent and temporary plots from roble (Nothofagus obliqua ), raulí (N. alpina) and coigüe (N. dombeyi) pure and mixed second growth forests located between 37°30 and 42°00 south latitude in Chile were used to fit an average size-density model. This model was then modified to obtain maximum density curves, and to construct stocking management charts with the aim to support planning of thinning, and to help the application of CONAF´s second growth forests management guidelines. The final size-density model considered a common slope and specific intercepts for three different compositions: raulí mixed, roble and coigüe. Comparisons of these models with others reported in the literature showed an acceptable level of similarity. Concerning load site capacity, the lowest levels were found for the composition roble, and the highest for coigüe. The following reference lines are suggested for the use of the presented stocking charts: 100% (line A or maximum density), 60% (line B or beginning of self-thinning), 30% (line C or load site capacity inferior limit), and 20% (line D or minimum density). Additionally, applications and methodology for the construction of these stocking charts are fully described together with concepts related to each of the reference lines. |

Un total de 214 parcelas permanentes y temporales de renovales puros o mixtos de roble (Nothofagus obliqua), raulí (N. alpina) y coigüe (N. dombeyi) localizadas entre los 37°30’ y 42°00’ de latitud sur en Chile fueron usadas para obtener un modelo de tamañodensidad. Este modelo fue posteriormente modificado para obtener curvas de densidad máxima y para construir diagramas de manejo de densidad con el objetivo de apoyar la planificación de raleos, facilitar la aplicación de las normas de manejo de renovales de la Corporación Nacional Forestal, CONAF. El modelo final de tamaño-densidad consideró una pendiente común e interceptos específicos para tres diferentes composiciones: raulí mixto, roble y coigüe. La comparación de estos modelos con otros reportados por la literatura indicó un grado aceptable de similitud. En relación con la capacidad de carga de uso del sitio se encontraron los niveles más bajos para la composición roble y los niveles más altos para coigüe. Se sugiere considerar las siguientes líneas de referencia para el uso adecuado de los diagramas propuestos: 100% (línea A o de densidad máxima), 60% (línea B o de inicio del autorraleo), 30% (línea C o límite inferior de ocupación del sitio) y 20% (línea D o nivel mínimo de densidad). Adicionalmente, el uso y metodología para la obtención de estos diagramas son descritos en detalle junto con conceptos relacionados a cada una de estas líneas de referencia.
