This paper aims at evaluating the role of standards in chestnut coppices from a biological and functional perspective. In addition to a detailed analysis of Italian regulations on the issue, the technical definition of the term is analysed: (i) as for the functional role of standards; (ii) to assess whether the required functions are technically necessary and are being actually performed. In this contex, the results of an experimental trial are reported. The goal of the trial were to assess the shoots’ parameters, the stand productivity, the dynamics of canopy cover in coppices with or without standards. In 2001, at harvesting operations in a coppice aged 30 with standards managed by the local community, two experimental plots 2500 m2 each were established. The two theses being compared were: simple coppice and coppixce with standards (100 standards per hectare). The released standards were qualified immediately after final harvesting.

First results highlighted the evidence of statistically significant differences between the two thesis. The high number of standards effected negatively both vitality and growth pattern of the stools. Simple coppice recorded a lower shoot mortality, a higher diametrical growth and canopy cover degree as well; the heigth growth was, on the opposite, significantly lower. These results, although referred to a limited lifespan (1/3 of the rotation time) and to one site only, underline productive, ecological and environmental benefits and as a consequence suggest the widening of the experimental network and the development of new, more relevant and consistent rules, making acceptable the simple coppice as a possible silvicultural choice to be applied to chestnut coppices.http://www.sisef.it/forest@/contents/?id=efor0705-009&lang=enCoppiceStandard releaseCastanea sativaStumps vitalityShoots growthCanopy cover |
