Bugoma Forest
The Bugoma Forest is a protected tropical forest that is situated southwest of Hoima and northeast of Kyenjojo towns, and east of Lake Albert, in the Hoima district of western Uganda. It was gazetted in the 1930s and came under the mandate of the National Forestry Authority (NFA) in 2003.〔 Its surface area is given as between 41,142〔 and 65,000 hectares.
==Setting and structure==
It is one of a belt of extensive, lowland forests along Uganda's western rift escarpment, that are believed to have been connected with one another and the Ituri forest in former times. The forest belt is situated between 500 and 1,650 metres a.s.l,〔 and Bugoma is situated at between 990 and 1,300 m elevation.〔 Regional rainfall ranges from 1 250 to 1,625 mm.〔 Farmlands and regenerating vegetation fringe the forests, which includes Elephant grass and ''Hyparrhenia'' grassland.
The tree cover of the forest belt shows a tendency toward monospecific dominance. Early colonising forest consists of a mixed forest with ''Alstonia congensis'', ''Trichilia prieuriana'', ''Khaya anthotheca'', ''Celtis mildbraedii'', and ''Cynometra alexandri'', among others. The climax forest that develops afterward depends on the altitude. From 1 000 to 1 200 m ''Cynometra alexandri'' is highly dominant (Uganda ironwood). ''Lasiodiscus mildbraedii'' and sometimes by Celtis spp. and Strychnos mitis sometimes dominate the understorey. Very large trees other than Cynometra alexandri occur, such as Khaya spp. and Entandrophragma spp. Patches of characteristic colonising species (e.g. Maesopsis spp.) mature alongside climax canopy species in a mosaic pattern in spaces left by the fall of large trees. Another type of climax community is the Parinari forest, consisting of almost pure stands of Parinari excelsa, associated in the understorey with Carapa grandiflora. Other understorey species are Craterispermum laurinum, Trichilia prieuriana and Pleiocarpa pycnantha.〔
