* Wide Range and Fluctuation: Rabbits are found across vast areas of Europe, from the Iberian Peninsula to the British Isles. Their numbers fluctuate constantly due to factors like weather, disease, predation, and human intervention (hunting, habitat loss).
* Lack of Comprehensive Data: There isn't a single, centralized database that tracks rabbit populations across the entire continent.
* Regional Variations: Rabbit populations vary significantly from region to region. Some areas might have high densities, while others have limited numbers.
Instead of a single figure, it's more accurate to say that European rabbits are a common and successful species in Europe, with their populations generally considered healthy in many areas.
