Contents The Ants of Africa
Ghana leaf litter survey - Belshaw & Bolton - December 1991-November 1992

Prepared from details in Belshaw & Bolton (1994) of leaf litter sampling in the moist tropical zone of Ghana with 14 areas of primary forest, 10 areas of secondary forest and 10 cocoa farms (see the Ghana Map).

At each site an area of about 1000 m was defined, within which ten 1 m quadrats were placed. On a single occasion, all the leaf litter in each quadrat was collected and ants extracted using a Winkler bag. The ants were pooled to form a single total for each site. From all sites and samples, a grand total of 43,824 ants in 197 species and 47 genera were recognised. All these are included in the Species list. Three species were found only in the soil samples and 18 species were felt to be "tourists", either being arboreal species foraging on the ground or Camponotus species, which forage on the surface rather than within the leaf litter.

The "Prior knowledge" column is from my study of the literature (the details can be seen in the related species pages on the website).
