Effects of Habitat Fragmentation on Alien Plant Invasion in Native Shrublands

Habitat fragmentation can promote alien plant invasions by increasing the exposure of the fragment edge to alien plants present in adjacent habitats. Yet, few studies have examined covariates that might exacerbate the effect of fragmentation on plant invasions. Here, we investigated the influence of grazing, fragment size and habitat structure on alien plant invasion of indigenous shrubland while considering plant growth form.
