J. Laborde and K. Thompson Colonization of limestone grasslands by woody plants: the role of seed limitation and herbivory by vertebrates Journal of Vegetation Science 24
In a factorial field experiment in limestone grassland, we found that grazing by vertebrates exerts a dual control on scrub invasion. Livestock maintains a dense, compact turf that interferes with the seed germination and seedling growth of woody plants. Grazing also gives rise to differential survival of woody species as a function of their ability to resist browsing.
