Utilizzo del telerilevamento per l’analisi della biodiversità strutturale: il caso studio della Riserva Forestale di Clöise (Asiago, VI)

The Forest Reserve called “Clöise” is located on the Asiago Plateau (VI). It has an extension of about 17 ha, occupied by a mixed forest with Spruce (Picea abies) Fir (Abies alba) and Beech (Fagus sylvatica) and without cutting activities since 60 years. In 2009 a permanent monitoring area of 1 hectare was established within the reserve with the aim of analyzing the structure and the forest dynamics without significant human disturbance. In July 2012 the entire forest reserve was covered by a LiDAR survey within the Alpine Project NEWFOR (NEW technologies for a better mountain forest timber mobilization). In the present work the preliminary results of the use of LiDAR technology for the analysis of structural biodiversity of the forest are presented. The data obtained from field measurements (position, height, species, canopy, projection) have been used to validate the same information extracted from the CHM. The field surveys show a good level of structural biodiversity even if the influence of past silvicultural treatments is still evident. The validation of the data extracted from LiDAR with the ground truth showed a good correspondence for what concerns the extraction of information regarding the dominant trees while problems have been encountered for the analysis of the undergrowth
