The initial data of a long-term research program directed towards determining the silvicultural choices for management of ageing holm oak coppices are reported. The various treatments being tested are the following: treatment A and B respectively with 50 and 250 reserve trees per hectare, all of the same age; treatment C with 140 reserve trees per hectare, with three different ages; treatment D, conversion into high forest; and treatment E, natural evolution (the control). A total of 15 permanent plots were established (5 treatments x 3 replicates) and the experimental design used is that of randomized blocks. The results presented regard the structural development of the coppice during the first two year after coppicing. Regeneration from seed showed a significant correlation with treatment. Data relative to the characteristics of the stands existing before the various interventions also are given. Such preliminary results need further periodical observations.

Abstract

The initial data of a long-term research program directed towards determining the silvicultural choices for management of ageing holm oak coppices are reported. The various treatments being tested are the following: treatment A and B respectively with 50 and 250 reserve trees per hectare, all of the same age; treatment C with 140 reserve trees per hectare, with three different ages; treatment D, conversion into high forest; and treatment E, natural evolution (the control). A total of 15 permanent plots were established (5 treatments x 3 replicates) and the experimental design used is that of randomized blocks. The results presented regard the structural development of the coppice during the first two year after coppicing. Regeneration from seed showed a significant correlation with treatment. Data relative to the characteristics of the stands existing before the various interventions also are given. Such preliminary results need further periodical observations.

Les résultats obtenus et ici présentés font partie d'un projet de recherche dont l'intention est d'individuer des possibles options de culture pour les taillis de chêne vert vieillis. On a confronté les 5 thèses suivantes (avec 3 répétitions): les thèses A et B avec respectivement 50 et 250 réserves par hectare ayant toutes le même âge; la thèse C avec 140 réserves par hectare, ayant 3 âges différents; la thèse D, conversion en futaie; la thèse E, évolution naturelle. Les résultats exposés concernent l'évolution du peuplement pendant les deux premières années du cycle productif. Pour ce qui concerne la regénération, la présence des semis semble être favorisée par un couvert pas trop excessif des réserves. Il s'agit quand même encore de résultats préliminaires qui dérivent de parcelles d'échantillonage permanentes où, chaque année, on réalisera des reliefs.
