Extirpation of prairie dogs may also lead to regional and native biodiversity reduction, elevated seed depredation, and also the establishment and spread of invasive shrubs.[23] Burrowing rodents may perhaps eat the fruiting bodies of fungi and spread spores by their feces, thus making it possible for the fungi to disperse and variety symbiotic relationships Along with the roots of crops (which usually are not able to thrive with no them). As a result, these rodents may possibly Enjoy a role in sustaining healthier forests.[25]
