The highest number are found in Central Otago, the McKenzie Basin, North Canterbury and Marlborough.
The European hare (Lepus europaeus occidentalis) was introduced into New Zealand in 1851. Similar to the European rabbit, which is in the same family but in a different genus, it is larger, has longer ears and forelegs, tends to stand more ‘upright’. They are more solitary animals that breed on the ground rather than in a burrow. They weigh from 2.5-7kg and are 48-75cm long, with a slightly longer tail. While they are regarded as a nuisance, they do not do the same damage to vegetation as rabbits.
The European rabbit (Oryctolagus cuniculus cuniculus), is a mammal native to Spain and Portugal. It was introduced into New Zealand in the early 1800s for hunting and food. Varying in colour from grey to brown, they are around 45cm long and weigh 1.5kg and have short fluffy tail. The ears are long. They live in social groups and breed in burrows.
Both hares and rabbits do better in dryer, agricultural and open plains regions.
Vegetation, including native plants, grazed by rabbits struggles and generally fails to recover.
Allowing rabbit populations to increase leads to an increase in cats and mustelids, illustrating the complexity of managing predator guilds around braided rivers
