Hainan hares ( (Lazell, et al., 2012)) are found only on the western side of China's Hainan Dao island.
- Other Geographic Terms
- island endemic
The natural habitat of Hainan hares is the grasslands and shrub-forests of Hainan, China. Historically, the hares inhabited most lowland areas of the island. In 1995, due to the loss of natural habitat, Hainan hares were found only near the ranger stations of two deer ranches. A 1999 survey found that the species was also present in Tongtieling Forest Area. (Lazell, et al., 2012)

- 0.00 to 984.25 ft
Dorsally, the hares have a a pale brown soft coat with tinges of black and chestnut. They have white circles around the eyes extending forward toward the muzzle and back toward the ear. On the ventral side, the coat is white. The feet are light brown with white markings and the tail is brownish-black on top with stripes oriented transversely, but pale to white on the bottom. Seasonal variation has been observed in the summer coat being less vibrant than the winter coat. This species of hare has short ears, which tend to be less than 95 mm in length. The skull is rounded with small auditory bullae, a broad, short rostrum, an upwardly directed suborbital process, and upper incisors forming a Y-shaped groove that is often filled with cementum.

Little is known about the reproductive behavior of Hainan hares. However, other common hares and jackrabbits that live near the equator breed throughout the year and have approximately 8 litters containing 1 to 2 young. Their closest relatives, Burmese hares, have a gestation period of 35 to 40 days. (Duckworth, et al., 2008; Myers and MacInnes, 1981)
- Key Reproductive Features
- gonochoric/gonochoristic/dioecious (sexes separate)
Though the parental investment of Hainan hares has not been investigated, most hares, pikas, and rabbits have limited parental investment compared to other mammals. Mothers typically visit their young to allow them to nurse once a day. Weaning typically occurs at 1 or 2 months of age and sexual maturity shortly following at roughly 4 to 6 months of age. Males are not involved in caring for the young. ("Rabbits Pikas and Hares: Lagomorpha - Behavior And Reproduction Read more: Rabbits Pikas and Hares: Lagomorpha - Behavior And Reproduction", 2012)
A shy and primarily solitary creature, Hainan hares are nocturnal with a majority of activity occurring before midnight. Hare activity has on occasion been observed during the day. Members of this species don't burrow. (Lazell, et al., 2012)
- Range territory size
- 2 (high) km^2
Hainan hares appear to be relatively sedentary. A territory size of less than 2 sq km was recorded for individuals living near two deer ranch ranger stations.
Communication and Perception
There is little information on communication and perception of Hainan hares. The species has external physical features associated with sight, touch, taste, and hearing. Other hares, pikas, and rabbits use pheromones and scent marks for perception. (Smith and Xie, 2008)
In their natural range these hares face little predation pressure, most likely due to low predator abundance in the region. (Lazell, et al., 2012)
The role of Hainan hares in the ecosystem has not been described. In the past, it may have been a significant prey species, as is the case for most common hares and jackrabbits. However, this is unlikely the case today, as populations have declined. (Lazell, et al., 2012)
Economic Importance for Humans: Positive
Hainan hares have historically been, and to a lesser extent still are, hunted for meat and skin. (Lazell, et al., 2012)
- Positive Impacts
- body parts are source of valuable material
Economic Importance for Humans: Negative
Hainan hares are of little significance economically. (Lazell, et al., 2012)
Due to expansion of land use for agriculture and harvesting, this hare has lost what is estimated to be upwards of 90% of its natural habitat, with less than 2 sq km left of optimal habitat. It is also under pressure from poaching for pelts and meat, and competition may exist with feral European hares, pikas, and rabbits. The Hainan hare is a China Key List - II protected species, but as of 1995 there were no laws regarding the conservation of this species. The species was Red Listed in 2008. The estimated population size is 250 to 500 individuals. (Lazell, et al., 2012)
