The abstract describes observations of young Eulychnia acida and Echinopsis chiloensis from 2009–2012 in Las Chinchillas reserve. It compares open sites with the microenvironment beneath five shrubs. E. acida was more frequently found beneath Bahia ambrosioides, now Eriophyllum ambrosiodes in POWO. The paper considers species-specific nurse plant effects.
