"A particular form of facilitation which is useful in plant community restoration is referred to as the "nurse effect" when an adult plant (the nurse plant) promotes the establishment of seedlings (the target plants; Niering et al., 1963). It may be decisive for plant establishment in primary or secondary successions, especially in harsh environments (Walker and del Moral, 2003), and sometimes involves microbial mediation (Duponnois et al., 2011)."
