- Please consider whether any information you would like to add is sensitive and could be misused to harm apes. Please do not add such information. If unsure, you can contact the Wiki manager (contact details on start page) for clarification.

- Text and images are not restricted, and their formats can be chosen as desired.  
−

- Tables and lists are extracted as data, so the following restrictions apply to them:
−
- Wiki site pages contain information in paragraphs of text, tables, keyword lists, and images
+
   1) Table structure cannot be changed.
−
- Text paragraphs and images are not restricted, so text format and images can be chosen as desired.  
+
   2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.  
−
- Tables and keyword lists are extracted as data, and so have the following restrictions:
+
   3) To make information comparable across wiki pages, keywords must be taken from the list of permitted words, or added to the list of permitted keywords. This is why we use official lists, e.g., IUCN classification lists, in our tables.

   2) Keyword format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.

   3) Keywords must be taken from the list of permitted words, or added to the list of permitted keywords. A link to the keyword list page is found adjacent

The Lac Tumba (or Lake Tumba) landscape is situated in western Democratic Republic of Congo, and extends into neighbouring Republic of Congo, forming the Lac Tumba-Lac Tele transboundary landscape. The landscape is made up mainly of marshes, seasonally flooded forests and meadows. It is home to the largest Ramsar freshwater wetland of international importance. The forest of Lac Tumba is the world’s largest swamp forest, and the world’s second largest wetland area (WWF n.d.). About 60% of the Lac Tumba landscape is inundated and seasonally flooded forest (Inogwabini et al. 2007). The landscape is home to a wide variety of large mammals, including bonobos, chimpanzees, Angolan pied colobus, Allen's swamp monkeys, black mangabeys, red colobus, red-tailed monkeys, forest elephants, buffalos and leopards (Inogwabini et al. 2007). In addition, the swamps have a rich diversity of fish and attract freshwater-dependent species such as sitatunga, water chevrotain, slender-snout crocodiles, Nile crocodile, and hippopotamus (Inogwabini et al. 2007).

Bonobo groups were found in five areas in a 2005 survey: (1) Bolombo-Losombo, (2) Mbala-Donkese, (3) Ngombe-Botuali, (4) Botuali-Ilombe, and (5) Mompulenge–Mbanzi-Malebo–Nguomi (Inogwabini et al. 2007). There were two sub-groups in the latter area, separated by 50 km of unbroken gallery forest, Mopulenge-Mbanzi and Malebo-Nguomi. One group of chimpanzees was found in the area between Bosobele and Lubengo (Inogwabini et al. 2007).

Poaching, habitat loss, and diseases are the main direct threats to bonobos in Lac Tumba (IUCN & ICCN 2012). Although logging has been considered moderately severe, the situation is considered reversible if sufficient efforts are made, such as closing of logging roads and rehabilitation of the natural vegetation (IUCN & ICCN 2012). Unmonitored fishing and bushmeat hunting are common at the site (Inogwabini et al. 2007). The Bateke people inhabiting the Malebo area believe that bonobos are their ancestors, and therefore a traditional taboo prevents them from hunting bonobos (Inogwabini et al. 2007).

Central Africa > Democratic Republic of the Congo > Lac Tumba landscape

Summary[edit]

  • Bonobos (Pan paniscus) and eastern chimpanzees (Pan troglodytes schweinfurthii) are present in the Lac Tumba landscape.
  • The population sizes are unknown.
  • The great ape population trend is unknown.
  • The site has a total size of 78,972 km².
  • Key threats to bonobos are poaching, habitat loss, and diseases.
  • Conservation activities are not documented.
  • The site holds the world’s largest swamp forest, and the world’s second largest wetland area.

Site characteristics[edit]

The Lac Tumba (or Lake Tumba) landscape is situated in western Democratic Republic of Congo, and extends into neighbouring Republic of Congo, forming the Lac Tumba-Lac Tele transboundary landscape. The landscape is made up mainly of marshes, seasonally flooded forests and meadows. It is home to the largest Ramsar freshwater wetland of international importance. The forest of Lac Tumba is the world’s largest swamp forest, and the world’s second largest wetland area (WWF n.d.). About 60% of the Lac Tumba landscape is inundated and seasonally flooded forest (Inogwabini et al. 2007). The landscape is home to a wide variety of large mammals, including bonobos, chimpanzees, Angolan pied colobus, Allen's swamp monkeys, black mangabeys, red colobus, red-tailed monkeys, forest elephants, buffalos and leopards (Inogwabini et al. 2007). In addition, the swamps have a rich diversity of fish and attract freshwater-dependent species such as sitatunga, water chevrotain, slender-snout crocodiles, Nile crocodile, and hippopotamus (Inogwabini et al. 2007).

Ape status[edit]

Bonobo groups were found in five areas in a 2005 survey: (1) Bolombo-Losombo, (2) Mbala-Donkese, (3) Ngombe-Botuali, (4) Botuali-Ilombe, and (5) Mompulenge–Mbanzi-Malebo–Nguomi (Inogwabini et al. 2007). There were two sub-groups in the latter area, separated by 50 km of unbroken gallery forest, Mopulenge-Mbanzi and Malebo-Nguomi. One group of chimpanzees was found in the area between Bosobele and Lubengo (Inogwabini et al. 2007).

Threats[edit]

Poaching, habitat loss, and diseases are the main direct threats to bonobos in Lac Tumba (IUCN & ICCN 2012). Although logging has been considered moderately severe, the situation is considered reversible if sufficient efforts are made, such as closing of logging roads and rehabilitation of the natural vegetation (IUCN & ICCN 2012). Unmonitored fishing and bushmeat hunting are common at the site (Inogwabini et al. 2007). The Bateke people inhabiting the Malebo area believe that bonobos are their ancestors, and therefore a traditional taboo prevents them from hunting bonobos (Inogwabini et al. 2007).

Table 3. Threats to apes in Lac Tumba landscape

Category Specific threats Threat level Quantified severity Description Year of threat
1. Residential & commercial development Unknown
2. Agriculture & aquaculture 2.1 Annual & perennial non-timber crops High Unplanned and unsustainable subsistence agricultural practices (Inogwabini et al. 2007). Ongoing (2007)
3. Energy production & mining Unknown
4. Transportation & service corridors 4.1 Roads & railroads Low Development of communications infrastructure (roads, railways) (IUCN & ICCN 2012). Ongoing (2012)
5. Biological resource use 5.1 Hunting & collecting terrestrial animals High Poaching is facilitated by increasing availability of weapons and ammunition and the location of the area at the junction of major river routes (Inogwabini et al. 2007, IUCN & ICCN 2012). Ongoing (2012)
5.3 Logging & wood harvesting High Legal and illegal industrial logging. Easy river access is used for transportation of timber to Kinshasa (IUCN & ICCN 2012). Logging for the wenge Mellitia laurenti (Inogwabini et al. 2007). Ongoing (2012)
6. Human intrusion & disturbance Unknown
7. Natural system modifications Unknown
8. Invasive & other problematic species, genes, diseases 8.4 Problematic species/diseases of unknown origin Present, but threat severity unknown Threat of disease (IUCN & ICCN 2012). Ongoing (2012)
9. Pollution Unknown
10. Geological Events Absent
11. Climate change & severe weather Unknown
12. Other options Absent

IUCN Threats list

Conservation activities[edit]

The landscape is a priority conservation landscape funded by the Central African Regional Programme for the Environment of the US Agency for International Development through the International Congo Basin Forest Partnership. The site was selected as a priority conservation site in 2000 (Inogwabini et al. 2007).
