|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.|
|Red List Category & Criteria:||Vulnerable B1ab(iii) ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Schiøtz, A., Howell, K., Pickersgill, M. & Loader, S.|
Listed as Vulnerable because its extent of occurrence (EOO) has been estimated as 16,959 km2, the ongoing threat of habitat loss and degradation means that the species' is thought to occur in fewer than 10 threat-defined locations.
|Previously published Red List assessments:|
|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. While its extent of occurrence (EOO) is 16,959 km2, it occurs only very patchily within the mapped range due to limited suitable habitat.|
Native:Kenya; Tanzania, United Republic of

|Population:||It is fairly abundant where it occurs. However, due to ongoing habitat loss its population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|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.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||There is continuing loss and degradation of its forest habitat due to the expansion of agriculture, wood extraction, and human settlements. Although it can tolerate a degree of 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.|
It occurs in the Shimba Hills National Park.
The maintenance and protection of tracts of lowland coastal forest habitat is essential to ensure the persistence of this species.
Further research is required on the species' taxonomy, population status, and life history and ecology. Ongoing monitoring would help to track the impact of habitat loss and degradation on the hybridization of the species with Afrixalus stuhlmanni.
