Currently, populations within the species’ native range (and throughout Europe) are dramatically declining45, most likely due to habitat loss as a result of intensified agricultural practices in combination with diseases like myxomatosis and rabbit calicivirus, as well as human-induced mortality45.
How do rabbits affect the ecosystem?
In their natural habitats, rabbits serve the two main functions of keeping plant life in check and providing food for carnivorous predators. Ultimately this encourages more biodiversity among the plants in the ecosystem. Rabbits also have nutrient dense urine and feces that can help revitalize soil and keep it healthy.
