Abstract
Forest structure mapping at forest stand level is a basic tool for decision making in sustanaible forest management. The LIDAR data, that provide direct measurements of forest canopy height, have important application in forest stand delineation. On ther other hand, landscape ecoloy is a discipline that quantify and characterize landscape units using several metrics. Regarding this, the objective of the present work is to study the utiltity and applicability of landscape ecology metrics to identify and charcterize forest stands structure units. To this purpose, 120 ha of Scot pine in Guadarrama mountains were analyzed and a forest structure cartography with five structure types based on LIDAR DCM data was considered. Different landscape metrics: patch density, shannon index, etc.. were calculated at landscape level with FRAGSTATS. In addition, an ANOVA test (structure type as factor) and Fisher LSD test were applied in order to evaluate the ability to discriminate among the 5 structure types of each landscape ecology index. Results show that landscape ecology metrics without spatial information are not properly able to recognize and differentiate forest structure types.
