- Abstract
The Maulino forest is a temperate ecosystem of the Mediterranean zone of Chile classified as one of the 34 biodiversity hot-spots of the world; however, there is still limited information about the ecological factors that make this native forest prone to be invaded. We assess to what extent forest attributes such as light availability and native species diversity control the invasion process of Teline monspessulana (L.) K. Koch, an aggressive weed, into the Maulino forest, an endemic forest ecosystem of Central Chile. We examined whether the seedling density of this exotic plant is related to forest attributes such as cover, incoming photosynthetically active radiation, litter depth, and native species density and richness. We found that a decrease of light availability reduces T. monspessulana invasion. No relationships were observed between native species diversity and the abundance of T. monspessulana plants. Increasing the forest cover will recover forest structure but at the same time, it will prevent the invasion of T. monspessulana and other exotic plants with similar regeneration niche requirements.
