| description | The objective of this work was the proposal of a method that allows quantitative measurement of effects of restoration activities at landscape scale, comparing an initial conservancy condition, with another one ideal, called reference landscape created by projecting the hoped for changes by restoring. Once the reference landscape was defined, an assessment of landscape indexes that allowed measure conservation gain by restoration was proposed. In order to achieve this goal, the work was developed in a basin with high conservation level. The landscape indexes used were: edge effects, diversity landscape index, form index and, spatial continuity index, applying each of them to the initial condition and to the reference landscape. For the studied case, the reference landscape was simple an easily defined, due to the vast amount of information available for the forest in the area. In the stage of landscape index evaluation, those ones with the best performance to measure conservation gain were edge effect and spatial continuity. Form index, instead, created confusing values between initial condition and reference landscape. So too, diversity index forced a complex analysis, mainly because restoration modified the class number between initial conditions and reference landscape. |

Once the reference landscape was defined, an assessment of landscape indexes that allowed measure conservation gain by restoration was proposed.

El objetivo de este trabajo fue proponer una metodología que permita medir cuantitativamente los efectos de actividades de restauración a escala de paisaje, comparando una condición inicial de conservación, con otra condición ideal, denominada paisaje de referencia, creada proyectando los cambios esperados por la restauración. Definido el paisaje de referencia se propuso evaluar índices de paisaje que permitieran cuantificar la ganancia en conservación lograda por la restauración. Para ello, se trabajó en una cuenca con alto grado de conservación. Los índices usados fueron: efecto borde, índice de diversidad del paisaje, índice de forma e índice de continuidad espacial, aplicándose cada uno de ellos a la condición inicial y al paisaje de referencia. Para el caso estudiado, el paisaje de referencia fue simple y sencillo de definir debido a la vasta información relativa a los bosques de la zona. En la etapa de evaluación de los índices del paisaje usado, los que presentaron el mejor desempeño para cuantificar la mejora en conservación fueron el de efecto borde y el de continuidad del paisaje. El índice de forma, en cambio, generó valores confusos entre la condición inicial y el paisaje de referencia, ya que el valor del índice aumenta o empeora solo por el aumento de la superficie. Así también el índice de diversidad obliga a un análisis complejo, principalmente porque la restauración modifica el número de clases de la condición inicial respecto al paisaje de referencia.
