Zusammenfassung: | The structure of a forest stand is the result of interactions between bio-ecological factors and human activities and is an important element for the analysis and the management of the forest ecosystems. In management terms, the study of the structural types makes it possible to assess the effects of silvicultural treatments implemented over the years in the forests and it is the starting point for defining appropriate management methods to adopt, in order to improve and promote the structural complexity of the stand and the system functional efficiency. The management methods of the Calabrian pine groves over the past thirty years, based on the elimination of individual plants, patch or strip clear felling and selection felling, have created diversified structural conditions over large areas. Pure, even-aged stands and uneven-aged pine forests alternate with stands that are dense and dynamic with abundant, young natural beech or, in the more advanced phases, young beech forests dominated by adult pines. These last two phases are chronologically sequential. This study covers the even-aged pine forest, the Calabrian pine forest with widespread regeneration of beech and the sparse Calabrian pine forest with young beech stands, each of which has undergone a detailed structural analysis. The objective is to highlight the relationships among the silvicultural treatments, the structural conditions and the evolutionary dynamics of the pine forests and to contribute to the development of guidelines for the sustainable management and the maintenance of these formations
La struttura dei popolamenti forestali è la risultante delle interazioni tra fattori bioecologici ed attività antropica ed è un importante elemento per l'analisi e la gestione degli ecosistemi forestali. In termini gestionali, lo studio dei tipi strutturali consente di valutare gli effetti degli interventi selvicolturali che negli anni si sono succeduti in bosco e rappresenta il punto di partenza per la definizione di appropriate modalità di gestione, in grado di migliorare e promuovere la complessità strutturale dei popolamenti e l'efficienza funzionale del sistema. Le modalità di gestione delle pinete di laricio negli ultimi trenta anni, basate sull'eliminazione di singole piante, sul trattamento a raso a strisce o a buche e su quello a scelta, hanno determinato condizioni strutturali diversificate su ampie superfici. Pinete pure a struttura coetanea e disetanea si alternano a pinete con una gradaz |
