Diradamenti di cedui castanili invecchiati - risultati di due parcelle sperimentali (1975–1997) a Novaggio, Ticino | Study of the Problem of Thinning Ageing Chestnut Coppice Forest over 25-Years-Old: Findings from Two Study Areas near Novaggio, in the Canton of Ticino (1975–1997)

A study was undertaken to determine the extent to which practical and scientific results of a study in the Swiss Central plateau can be applied to the chestnut coppice to the south of the Alps in Switzerland. The Central plateau study was carried out using selective thinning in former coppice with standards and seedling forests. The neglect of the chestnut coppices which occurred during the early 1970s made this a topical issue at the time. With this in mind, our experiment was primarily aimed at answering the following question: Can selective thinning contribute to the long-term transformation of these chestnut coppices, and eventually bring about natural regeneration through seedlings? Particular interest was paid to the effect it has on improving timber production, timber quality, vitality, and species mixture. Two stands were selected for the study: these were sufficiently large to produce valid results, and had as homogeneous a structure as possible. One was a typical stand of chestnut coppice forest...
