Pigeon Valley is a Natural Heritage Park and formally declared municipal nature reserve in Durban, South Africa. It is an unusual example of an urban reserve with very high levels of biodiversity. It was established to provide protection for the Natal elm and other forest giants of the coastal climax forest. Another rare tree that occurs here is Natal forest loquat, which is endemic to the Durban area and to oNgoye Forest. Pigeon Valley is about 11 ha in extent, and is situated on the Berea, overlooking Durban Bay. Its unusual north-south orientation may contribute to the biodiversity, with the south-facing slope covered in canopy forest, while the north-facing slope has thorny thickets. An adjoining reservoir, previously part of the reserve, provides a patch of coastal grassland.
The reserve is excellent for its butterflies, and the total listing is now 92 species. In September 2018 the first pupae of the short-barred sapphire were found on a Celtis mildbraedii tree. The host plant is the Oncocalyx quinquenervius mistletoe, which grows profusely on the tree. Subsequently a red-line sapphire was found at the same spot. The first forest queen was found in 2019.
Plants
There are over 110 species of trees occurring in Pigeon Valley, almost all of which are locally indigenous. Pigeon Valley is also notable for large stands of buckweed, which grow in more open areas under the forest canopy and in forest glades. In recent years there have been a few discoveries of plants not previously identified. Pigeon Valley is unique in having large numbers of the rare Natal elm, and of Natal forest loquat. A Cryptocarya specimen found adjacent to the main track has so far not been definitively identified; it may be a species seldom found in the area or alternatively a hybrid. in this urban reserve, where it is a winter visitor
Public access
The reserve is open from 07:30 to 16:00 daily throughout the year. The entrance is in Princess Alice Avenue, Glenwood, opposite Rhodes Avenue.
Community
An active grouping, Friends of Pigeon Valley, undertakes clearing of invasive alien plants, ensuring that the park is unusually free of alien species. It also liaises with the municipal managers of the reserve to address relevant issues. The Friends operate a monthly walk open to the public on the second Saturday of each month, at 07h30.
