Afrixalus sylvaticus 


Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Hyperoliidae

Scientific Name: Afrixalus sylvaticus
Species Authority: Schiøtz, 1974
Taxonomic Notes: Pickersgill (2000, 2005) considers this form to be a subspecies of Afrixalus stuhlmanni, with which it hybridizes as forests are cleared. We follow Schiøtz (1999, and pers. comm.) in considering it to be a valid species. However, we follow Pickersgill (2005) and K. Howell (pers. comm.) in considering it to occur in the coastal areas of Tanzania, as well as in the Shimba Hills in Kenya.

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Martin Pickersgill, Arne Schiøtz, Kim Howell
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Endangered because its Area of Occurrence is less than 500km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat along the Kenyan and Tanzanian coasts.

Geographic Range [top]

Range Description: This species ranges from the Shimba Hills in southern coastal Kenya south through the East Usambara foothills in north-eastern Tanzania, as far south as the Kazizumbwi Forest in central coastal Tanzania. There is an unconfirmed record from further north along the Tana River in eastern Kenya. It occurs only very patchily within the mapped range due to limited suitable habitat.
Countries occurrence:
Kenya; Tanzania, United Republic of

Population [top]

Population: It is fairly abundant where it occurs.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It is a species of lowland forest that can survive in secondary growth and plantations, but not in completely degraded habitats. It breeds in temporary pools and water-filled depressions in forest.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Although it can tolerate degraded forest and secondary growth, these habitats are also known to be suitable for A. stuhlmanni with which this species hybridizes, and this is probably the most serious threat to the species.

Conservation Actions [top]

Conservation Actions: It occurs in the Shimba Hills National Park, but the maintenance and protection of other tracts of lowland coastal forest habitat is essential to ensure the persistence of this species.
