However, it is not fully clear how far into the extracted peatlands the propagules could be carried, how much the re-vegetation is influenced by the type of the adjacent vegetated areas, and how much the germination of the arriving propagules and the survival of plants depend on the growth conditions or on autecological differences between plant species.

montana was first classed as a successional species based on its capacity to regenerate on steep slopes where landslides were common (Beard, 1949), autecological research in the Quebrada Sonadora watershed showed that Prestoea grew slowly, survived for long periods, adapted well to shade, and had a high moisture requirement, all suggesting that the species was adapted to closed forest (Bannister, 1970).
