    Biodiversity of Karuma Wildlife reserve based on studies conducted in two of the encroached areas, the Kibyama and Mpumwe villages.
    (EPED Project, 1997) Behangana, Mathias; Etyang Hillary, Patrick; Bakamwesiga, Isaiah Owiunji Andrew Martin (
    Karuma Wildlife Reserve lies in an enclave of protected areas which comprise of Murchison Falls National Park, Bugungu Wildlife Reserve, Kaniyo Pabidi and Budongo Forest Reserves. This system of protected areas mostly lies in Masindi District western Uganda and was traditionally an expansive ranging ground for large game like elephants and buffaloes besides the smaller species.

    The biodiversity of the Albertine Rift
    (Biological conservation, 2007) Plumptre, Andrew J.; Davenport, Tim R.B.; Behangana, Mathias; Kityo, Robert; Eilu, Gerald; Ssegawa, Paul; Ewango, Corneille; Meirte, Danny; Kahindo, Charles; Herremans, Marc; Peterhans, Julian Kerbis; Pilgrim, John D.; Wilson, Malcolm; Languy, Marc; Moyer, David
    The Albertine Rift is one of the most important regions for conservation in Africa. It contains more vertebrate species than any other region on the continent and contains more endemic species of vertebrate than any other region on mainland Africa. This paper compiles all currently known species distribution information for plants, endemic butterfly species and four vertebrate taxa from the Albertine Rift. The literature on fish species richness and endemism is also reviewed to assess the importance of the larger lakes in the Rift for conservation. We use data from 38 protected and unprotected areas to prioritise sites within the Albertine Rift for conservation based upon their numbers of endemic and globally threatened species. Virunga and Kahuzi Biega National Parks and Itombwe Massif in Democratic Republic of Congo, Bwindi Impenetrable and Kibale National Parks in Uganda, and Nyungwe National Park in Rwanda rank highest in terms of numbers of both endemic and globally threatened species. Six conservation landscapes are described that include most of these sites and it is argued that a focus on these landscapes may be a more holistic method to ensure the safety of the priority areas of the Albertine Rift.

    Conservation of vertebrates and plants in Uganda: Identifying Key Biodiversity Areas and other sites of national importance
    (Conservation Science and Practice, 2019) Plumptre, Andrew J.; Ayebare, Sam; Behangana, Mathias; Forrest, Tom G.; Hatanga, Paul; Kabuye, Christine; Kirunda, Ben; Kityo, Robert; Mugabe, Hamlet; Namaganda, Mary; Nampindo, Simon; Nangendo, Grace; Nkuutu, David N.; Pomeroy, Derek; Tushabe, Herbert; Prinsloo, Sarah
    Uganda is one of the most species rich countries in Africa because of the presence of several major biomes. However, it is also a country that has lost much of its natural habitat to agriculture. Uganda is a country that has been better surveyed for its biodiversity than many African countries, but despite this, there has not been a comprehensive analysis of the critical sites that contribute to biodiversity conservation at a global, as well as at a national level. We here present such an assessment using mammals, birds, reptiles, amphibians, and plants as surrogate taxa. We identified 36 terrestrial sites that are of sufficient global importance to qualify as Key Biodiversity Areas (KBAs), using the Global Standard for the Identification of KBAs, which complement an additional nine freshwater sites. National red listing of species and ecosystems was used to identify sites of national importance for conservation. We employ a conservation planning approach using Marxan to identify the minimum set of sites needed to conserve all the globally and nationally threatened species and nationally threatened habitats in Uganda. The findings show that most of the remaining natural habitat in Uganda is important for the conservation of globally and nationally threatened species and threatened habitat. Large areas of irreplaceable habitat occur outside protected areas, although more extensive surveys of these areas would likely reduce the area that is irreplaceable.

    Effects of selective timber harvest on amphibian species diversity in Budongo forest Reserve, Uganda
    (Forest Ecology and Management, 2020) Lukwago, Wilber; Behangana, Mathias; Mwavua, Edward N.; Hughes, Daniel F.
    We studied the effects of forest management on amphibian communities in the Budongo Central Forest Reserve, Uganda. We sampled amphibians from May to August of 2012 in four compartments with different logging and arboricide-treatment histories. We used pitfall traps with drift fences combined with visual encounter surveys to sample amphibians from 36 plots in four 1-km long transects along the Sonso River. From 126 encounters across plots, we recorded 25 frog species belonging to six families and eight genera. Arthroleptidae was the most diverse family represented by 10 species within two genera. Arthroleptis had the highest number of species (six), Ptychadena the second most (five), followed by Leptopelis (four) and Sclerophrys (four). Species composition differed across transects. The unlogged study site possessed the highest species richness, diversity, and evenness, and had the greatest frequency of species encounters. The most heavily logged site had the lowest species diversity and fewest amount of species encounters. This site also had the most dissimilar species composition among sites and was significantly different in species richness compared to the unlogged site. The two moderately logged sites had the second and third most species, and had the most similar species composition to each other. Our study provides data on the amphibian species of a protected site in the Albertine Rift, part of the Eastern Afromontane biodiversity hotspot, and results suggest that the forest management regimes in Budongo have exerted an influence over the amphibian communities after more than 50 years of forest recovery.

    How many reptile and amphibian species are in Uganda, and why it matters for global biodiversity conservation
    (PeerJ. Ltd, 2025-01) Hughes, Daniel F; Behangana, Mathias
    Biodiversity is unevenly distributed across the globe. Regional differences in biodiversity impact conservation through the allocation of financial resources, development of infrastructure, and public attention. Such resources are often prioritized to areas that are in more need than others. However, reasons for deciding which locations are more deserving are derived from an accurate knowledge of the number and composition of species that occur in each region. Regional differences in biodiversity, however, can reflect differences in the source of information consulted, rather than bona fide differences between areas. As a result, conservation resources may not be directed to regions in proportion to their actual need, especially if there is no consensus among sources of information. Here, we compared major sources of information on species of reptiles and amphibians that occur in Uganda, Africa. We found that none of the sources agreed on the total number, nor composition, of species in the country, with estimates for amphibians ranging more widely than those for reptiles. Notably, sources with similar species richness differed in species composition, which had an impact on the number of threatened species in the country. These results for a conspicuous group of vertebrates suggest that lesser-known groups are also likely misrepresented in sources, especially in other underexplored regions of tropical Africa. We discuss the implications for biodiversity conservation that are derived from inaccurate species lists that are commonly used by agencies, scientists, and practitioners. We argue that more critical evaluations of biodiversity resources, in addition to greater capacity building for field programs, taxonomy, and museum collections, will be essential to ensure that resources are allocated to regions that need them the most.
