Abstract


(Silvicultural prescriptions for density management of even-aged stand of sessile oak (Quercus petraea Matts. Liebl.) in the Cantabrian range are presented. The methodology of the study was based on a synchronic approach. Even-aged stands of every stage of development of the species were analysed in order to reconstruct the chronological series of sessile oak. The field work methodology can be adapted to any forest species and allows a single person to cover a wide study area.

The results of the present study are based on the analysis of 32 plots with dominant heights between eight and twenty-two meters. A silvicultural norm (regression line of density on dominant height) is obtained for even aged stands of oak as well as the recommended values of the Hart index for the species in a management model of multiple (productive and-protective) use. The mathematical expression of the norm is: 1n(N/ha) = 11,1347 –1,64823 * 1n(H0) or (N/ha = 69671,68061 * H0–1,64823). The recommended values of the Hart index for even aged stands of the species are situated in the interval S(%) _ [24,26].

The results are a first approach to the density management of the species.
