Site description The range of low hills running south-west from Dar es Salaam to the border of the Selous Game Reserve attracts higher rainfall than the coastal plain and this has resulted in the development of evergreen forest with a poor ground flora on the mainly dry sandy soils. Three Forest Reserves comprise this site: Pugu Hills Forest Reserve (2,180 ha), of which less than 400 ha remains in reasonable condition; Kazimzumbwi Forest Reserve (4,887 ha), of which perhaps only 900 ha can be considered forest; and Ruvu South Forest Reserve (35,000 ha), of which only 10,000 ha can be considered forest. The north-eastern corner of Ruvu South comes within 1 km of the north-western end of Pugu and is only 2 km from the western edge of Kazimzumbwi. Forest composition varies considerably between the three reserves, largely due to the past removal of valued timber, but also reflecting differing soil and groundwater conditions. The only tall (35 m) emergents in Pugu are a few Antiaris toxicaria and Dialium holtzii in the Msimbazi valley. There are even fewer tall emergents in Kazimzumbwi, and Ruvu South is characterized by extensive Zanzibar–Inhambane scrub-forest that may be natural climax vegetation. There are also large stands of riparian forest in Ruvu South, as well as at least two swamps and areas of grass-covered flood-plain. The site has two major railway systems passing through it; the need to protect embankments and cuttings should help ensure some forest remains on the steeper slopes.Vikindu Forest Reserve (1,599 ha, much of which is plantation), to the south of Dar es Salaam, was known to hold Anthus sokokensis, but is so badly degraded that attempts to protect it were abandoned and it has not been included in this site.
