Extirpation of prairie canines could also contribute to regional and local biodiversity reduction, increased seed depredation, along with the establishment and unfold of invasive shrubs.[23] Burrowing rodents may possibly eat the fruiting bodies of fungi and distribute spores by their feces, thereby permitting the fungi to disperse and kind symbiotic relationships Together with the roots of plants (which usually are unable to thrive with no them). As a result, these rodents might Participate in a job in keeping nutritious forests.[twenty five]
