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.[3] Wildlife23 species of mammal, 225 species of bird, and 260 species of tree are known to occur in the reserve.[1] Conservation statusThe forest is threatened by illegal logging,[1] and it is feared that it may succumb to settlement and agriculture. The situation is worsened by an influx of Congolese refugees, and burgeoning large-scale tea and tobacco farms on its outskirts that infringe on the reserve boundaries.[1] In March 2012 some 1,500 land invaders were evicted, but by December 2013 some of them were returning to start subsistence cultivation and pit sawing.[4] See also
