Criteria identification to select early thinning treatments in Pinus nigra ssp. laricio Arn. stands in the Basque Country

A. Aunos

Abstract


The main objective of this study was to identify the best thinning treatment for young Pinus nigra ssp. laricio Arn. stands in the Basque Country. Felling selection criteria qould be based on individual tree attributes and vertical stratification. Data collected in the field indicate that the stands to do not show a tendency to vertical stratification. Individual tree characteristics are not distinctive enough to support felling decisions. Consequently, only operational aspects should be considered when planning treatments in young stands. Low thinning should be preferred over selective thinning at this stage of development in the stands.
