MIRANDA, ALEJANDRO et al. Natural regeneration and spatial distribution patterns of Chilean palm Jubaea chilensis (Molina) Baillon in Mediterranean forests of Central Chile. Gayana Bot. [online]. 2016, vol.73, n.1, pp.54-63. ISSN 0717-6643.

Jubaea chilensis is an endemic tree of Central Chile (31º15’-35º22’ S). The current main conservation threats for this species should be associated with different factors which limit its natural regeneration, in particular the intense seeds crop. The analysis of spatial distribution patterns can be an important tool to understand the forest dynamic and the individual interactions. In this study was studied the spatial pattern of species recruitment and identifying the proper conditions for its regeneration. We predicted a clear spatial clumped pattern between regeneration individuals for all distance range studied, and also a clumped distribution associated to adult individuals. Spatial modeling showed that natural regeneration of J. chilensis is significantly related to higher vegetation cover, and especially in those with higher solar radiation. The results suggest that clumped regeneration of J. chilensis could be explained by the associated environmental conditions promoting the establishment of new seedlings, its seed dispersal mechanism, predation avoid, herbivory, and seeds crop. We also found a nurse effect which facilitates the natural regeneration of this species.
