There are several mechanisms by which such communities can have this feature. First, a diverse assemblage of species or functional types can use the surrounding resources more completely, and thus prevent invasives from easily being able to exploit an empty niche. Second, a diverse community has a greater degree of interspecific competition, which again means that it will be more difficult for invasive species to gain a foothold.
