Kibale Primate Destinations

Primates are very common in Kibale National Forest. The forest has some of the highest abundances of species of primates in the area. There are many species of primates and these species persist in the less disturbed areas of the forest in their natural habitats. There are disturbances that are hindering some of these species.
Disturbance Effects on Primates
Many studies have been conducted to determine the effect of different disturbances on primates. Many of these studies have found that there is a decline in the amount of primates in differently disturbed regions. One study found that there was a reduction in primate number but that primate abundance was still high in the remaining forest of the southern corridor (Chapman and Lambert 2000). Some disturbances studied have been commercial logging, degraded agricultural lands, and fragmented forest. All of these studies showed that there is a wide variety of primates affected by different disturbances, and some are not affected by any. In all of the cases it shows that because of the variable effects on different species that all forms of human disturbance should be as minimal as possible, at least until further studies have been conducted to know the full effects of these disturbances.
Logging Effects on Primates
Logging effects have been studied specifically by a few people. Most studies find that logging seems to be having a negative effect on the species but there are some contradictions.
Chapman and Lambert (2000) found that some species of primates are found less frequently in logged areas but others were unaffected. This study helps reveal the importance of stopping logging in certain regions of Kibale National Forest. The species from the study are shown below. These species densities show the effect of logging on each separate species:
* Heavily Logged areas:
* Found in lower densities: Chimpanzees (Pan Troglodytes), Red tails (Cercopithecus ascanius)
* Found in mixed densities: Red Columbus (Procolobus badius), Black-and-white Columbus (Columbus guereza)
* Unlogged areas:
* Found in mixed densities: Red Columbus (Procolobus badius), Black-and-white Columbus (Columbus guereza)
Another study conducted by Chapman and her colleagues in 2000 showed that many species of primates returned and came back to their original densities in lightly logged forest but in the heavily logged forest primates species were not able to recover. This study helps support that Kibale National Forest needs to develop a light logging system different from their heavily logging system they conduct now.
Degraded Agricultural Lands Effect on Primates
Degraded lands occur when land is cleared for agriculture and then abandoned after a few years. These lands are coming back at different rates and some are showing no possibility of re-growth. The effect these lands have on primates is still slightly unknown but some studies have started weeding out answers. One study found that most species of primates were found evenly distributed throughout the entire forest, whether there was agriculture encroachment or not (Chapman and Lambert 2000).
Fragmentation Effects on Primates
Fragmentation happens when a forest or habitat is broken into patches by outside disturbances. A fragmentation study done by Onderdonk and Chapman in 2000 showed an overall non-generalization on primates within fragments on the edge of Kibale National Forest. The species found in the fragments highlighted by the study are shown below. These species distributions show how fragmentation is affecting each species:
* Found in almost all fragments: Black-and-white Columbus (Columbus guereza), Red-tailed guenons (Cercopithecus ascanius)
* Found in some fragments: Pennant’s red Columbus (Procolobus pennantii), Chimpanzees (Pan Troglodytes)
* Found in no fragments: Blue monkeys (Cercopithecus mitis), Gray-cheeked mangabeys (Lophocebus albigena)
Diet of Primates in Kibale National Park
Different species have different diets and many of the species are folivorous. One study actually found that black-and-white Columbus monkeys (Columbus guereza) eat younger leaves over older leaves (this is thought to happen because the leaves have more protein and are easier to digest) (Chapman et al. 2004).
Flora
Kibale Forest National Park

There are approximately 229 species of trees found within the moist tropical forests of the park. Some endangered timber species of trees include Cordia millenii, Entandrophragma angolense, and Lovoa swynnertonnii. The forest understory is dominated by shade-tolerant shrubs and herbs, which include Palisota schweinfurthii and Pollia condensate, in addition to ferns and broad leaf grasses.
