“…The fi re-associated triggers analyzed in this study (heat, smoke, and the combination of both), did not increase the mean number of exotic over native species, or the density of exotic over native seedlings that emerged from soil samples taken from a Chilean matorral that has not been affected by fi re over the last 50 years. Although, it is hard to evaluate plant establishment by using post-fi re emergence only (Daws et al 2007), our results are consistent with those found by Keeley & Johnson (1977) and Holmgren et al (2000), where they suggest that fi re has no direct effect on the abundance and composition in the vegetation of central Chile. The aforementioned studies showed evidence that the establishment of exotic (e.g., Lophocloa cristata (L.) N. Hylander, Erodium cicutarium (L.) L'Hér.…”

“…is not stimulated by fi re. It is worth mentioning that our soil samples were collected in the same site where the study by Holmgren et al (2000) was carried out, although the fire intensity probably was lower than the heat treatments used in the present study.…”

“…Several studies have associated the naturalisation (i.e. exotic plants that have been able to establish and self-perpetuate in a new area, according to the definition provided by Richardson et al [48]) of those plants with processes of grazing by livestock [73][74][75][76]. Thus, although Chilean and Spanish plant communities have undergone different processes of invasion, previous reports highlighted the large number of species common to both regions (64% of Chile's non-native flora, [77]).…”

“…As a consequence, natural and ancestral cultural factors based on silvo-pastoral activity converge in the Mediterranean biome, involving the establishment of disturbance regimes that favoured the entry of alien species [73,83]. Due to the historical-cultural context of the colonialism [19], Europe, and especially the Mediterranean basin, has constituted the main source area donor of exotic flora to the whole Mediterranean biome.…”

“…Los resultados sugieren que los matorrales contribuyen a la persistencia de las especies herbáceas nativas asociadas al arbolado, y este papel puede ser especialmente importante cuando el arbolado no es demasiado denso. (Pineda et al 2002), la naturalización de las especies herbáceas exóticas explicaría el aumento de los valores de diversidad del pastizal, en detrimento de la diversidad de nativas, como se ha descrito en la zona central de Chile (Aronson et al 1998, Holmgren et al 2000. Es posible que la antigüedad de la intervención forestal determine la influencia de la cobertura arbolada en el valor de conservación de la diversidad biológica de los pastizales (Roberts y Gilliam 1995, Lencinas et al 2008, 2011).…”
