Spatial structure of the regeneration of Scots pine under two silvicultural systems
This paper is focused in the assessment of the effects of Silviculture on the structure of two even-aged Scots pine stands across a rotation period. For this purpose, 2 plots of 0.5 ha in different aged stands were established in two Scots pine forests with different management systems in the Central Mountain Range of Spain. To asses the spatial pattern the L(d) function were employed. To analyse the spatial relationship between the mother trees and the recruitment, a function derived from K(d) function was used. In Valsaín forest, the shelterwood fellings are carried out gradually over a irregular spaced stand, leading to a mixture of several cohorts and a cluster spatial pattern at 15-20 m for the stem distribution during the shelter phase. The regeneration showed repulsion from the old crop at very short distances and at distances greater to 15 m. In Navafría forest, the regular distribution of the trees and the short period used to regenerate the stand led to a positive spatial association between the mother trees and the seedlings at large scale.
