This report focuses on the non-woody components of tropical forests, such as herbaceous plants. It is the result of a project carried out in several forests in Western Uganda and Eastern Zaire from 1994 to 1996. The project was carried out by the Danish Centre for Tropical Biodiversity (The Botanical Museum, Copenhagen) in collaboration with several institutions in Uganda and the Democratic Republic of Congo (Zaire). Tropical forests are objects of increasing interest for their importance to the global environment. Forestry studies have so far solely been focused on trees, despite the fact that forest floor plants have the advantage of easy access. The aim of the project was to assess patterns of botanical diversity within and between forests in Western Uganda. The main emphasis was on the ground herbs, especially the ferns. The most significant output at this stage is the documentation of species. Appendices list the diversity of species for each Ugandan site.
