Interesting Facts
- Riverine Rabbit (Bunolagus monticularis) is assessed as Critically Endangered. The species is found only in the central Karoo region of South Africa and the current population is estimated to be fewer than 250 breeding pairs. With ongoing habitat loss and fragmentation , and direct threats from trapping , feral cats and dogs, and hunting pressure , the population decline is not expected to stop in the near future. (Ref 100465)
Common Names
Common Names in English:
Bushman hare, Riverine rabbit
Description
Habitat
Biome: Terrestrial [1].
Ecology:
The Riverine
Rabbit inhabits dense riparian
growth along the seasonal
rivers
in the central Karoo (Nama-Karoo - shrubland). Occurs specifically
in riverine vegetation on alluvial soils adjacent
to seasonal rivers.
The habitat
is highly fragmented
and transformed. Studies show the
habitat to be 67% fragmented in certain areas that can be considered
representative of the entire distribution.
STATE OF HABITAT:
Fragmented.
CHANGE IN HABITAT SIZE: Decreasing in area.
RECENT
CHANGE: 51%-80%.
DURING HOW MANY YEARS? 100.
PREDICTED
DECLINE IN HABITAT PREDICTED DURATION OF DECLINE: 100.
PRIMARY
CAUSE OF CHANGE: Cultivation and livestock farming.
CHANGES
IN QUALITY: Decrease in quality.
NOTES
ON QUALITY: livestock
and cultivation.
HABITAT NOTES: Habitat not being minimally
transformed at present. subpopulations
isolated from each other by
jackal-proof fencing and severe land
transformation
through agricultural
practices.
Generation length
for this species is two years
(Collins et al.
2004). This species has a single litter
per year with 1-2 young per litter (Duthie 1989). Reproductive periodicity
occurs from August through May (Duthie and Robinson 1990). Gestation
time is 35-36 days (Duthie 1989). Longevity
in captivity is five
years (Collins et al. 2003). Home range
is 12 ha (Duthie
1989). Total length ranges
from 33.7-47.0 cm (Nowak 1991). (Ref.
259306).
