Publication Title The Chimpanzees Of Oluwa Forest Reserve, Southwestern Nigeria
Publication Authors Ogunjemite, B. G and Olaniyi, O. E.
Year Published 2012

The lack of accurate information on the population of chimpanzees (Pan troglodytes) is a cause for concern on their conservation and management in Southwest Nigeria. We conducted surveys on the chimpanzees of Oluwa Forest Reserve, Ondo State between the month of September 2011 and February 2012. We used the combination of recce survey and GIS mapping to determine Chimpanzees’ locations in the reserve. Chimpanzee distribution was confined to the central portion of the OA2 axis of the reserve. This portion is approximately 39.22km2 representing 5.78% of the total size of the original area of the reserve. Four sightings of Chimpanzee groups were achieved with an average of 9.50 ± 1.55 individuals observed. We observed nests built on rock platforms. The numbers of tree nests observed at sleeping sites were usually fewer than the number of animals seen, indicating that not all of them build nest on trees at their nesting sites. These observations were new in nesting behavior of chimpanzees across Nigeria and it is postulated to be on account of insecurity and deprivation of essential material necessary for nesting in their night sleeping sites. We explained this on the conceptual frame work of psycho-infrastructuralism model.

Publication Title Relationship Between Anthropogenic Activities And Occurrence Of The Chimpanzees (Pan Troglodytes) In Oluwa Forest Reserve, Nigeria
Publication Authors           Olaniyi, O.E., Ogunjemite, B.G. and Dansu, E.J.       
Year Published 2014

This study determined the intensity of anthropogenic activities that took place within the chimpanzees’ distribution area in Oluwa Forest Reserve, Southwest Nigeria, and the anthropogenic activities having significant influences on the occurrence of this species. A binomial Generalized Linear Model with a logit link was employed in fitting the anthropogenic activities-Chimpanzees’ occurrence relationship model. Eight human activity indicators were observed, while backward stepwise variable selection algorithm was used for selecting the most significant ones. The encounter rates per kilometer of human activity indicators in the rainy and dry seasons ranged from 0.46 to 1.84 and 0.57 to 2.53 respectively. The model had Akaike’s information criterion of 22, and six anthropogenic activities were observed to have significant influences on the occurrence of chimpanzees namely; current or past agricultural activity, snareline, tree cutting/ timber extraction, regularly used human trails, matchet cuts or broken stems and bark stripping but, campsites were insignificant. Therefore, agricultural activities, timber extraction and hunting are major human threats to this disturbed enclave and their control is quite pertinent in order to curbing these environmental menaces. Control measures such as encouragement of forest guards to intensify anti-poaching and encroachment patrol, and adaptation of community- based participatory management approach in integrating the host communities of this reserve to ensure continual perpetuity of this species are necessary. These mitigating steps will bring effective and efficient management of chimpanzees towards their continued survival in the forest.

Year Published 2014
The Mona monkey (Cercopithecus mona) are widely distributed in Nigeria having urban, peri-urban and wild
populations but with little or no knowledge about their activities in the country. Daily activity budget of the animal
was studied in Ibodi Monkey Forest, Osun State, Nigeria in February and June 2013 to determine the behavioural
categories and daily activity budget. Direct observations were undertaken for twenty days, 10 days each in both dry
and rainy seasons. T statistic was applied in the analyses of the dataset obtained at Plocomotion, resting, feeding, playing, vocalization, grooming, agonistic and mating were observed in both dry and
rainy seasons. Mona monkey used most of their time for moving (32%), followed by feeding (25%), then resting
(23%) while playing and grooming had 11% and 6% respectively. During the dry season, the highest period was
also expended on locomotion (37%), followed by feeding (32%), then resting (16%) while playing, vocalization,
grooming and agonistic had 5%, 6%, 2% and 2% respectively, while none on mating. The t statistics of the daily
activity budget between rainy and dry seasons revealed that locomotion (t= - 0.12, P= 0.90), feeding (t= - 0.95, P=
0.37), and agonistic (t= 0.77, P= 0.45) were not significantly different (P>0.05), while resting (t= 8.16, P= 0.00),
playing (t= 18.22, P= 0.00), vocalization (t= -11.35, P= 0.00), grooming (t= 11.95, P= 0.00) and mating (t= 2.27, P=
0.04) were significantly different over seasons (Pdevelopment of the site ecotourism purposes and ensure effective conservation and management of this species in

Publication Title The Quantification Of Threats To Chimpanzees’ Habitat Of Oluwa Forest Reserve, Southwest Nigeria.
Publication Authors Olaniyi, O.E. and Ogunjemite, B. G
Year Published 2013

Throughout their range, Chimpanzees are threatened by deforestation, poaching, diseases, and capture for the pet trade and research purposes. The populations of Chimpanzees in South west Nigeria are extremely depleted and Oluwa Forest Reserve, in Omo Cluster, is adjudged as one of the exceptional sites for their conservation in the region in the recently produced action plan for the animal. This study quantifies the level of threats on the population in the reserve. Observations of threats to chimpanzees were carried out through ‘recce’ survey in the core distribution area of chimpanzee in the reserve. Information on threat activity gained from recce path provides an index of the type and intensity of human use of an area. These indices were compared over seasons using T – test analysis. Eight types of human  activities were observed as threatening to chimpanzees in the reserve; regularly used human trails, roads (Used or disused), snareline, campsite (Active or abandoned), tree cutting/ timber extraction, current or past agricultural activity, bark stripping and matchet cuts or broken stems. The average number of human activities encountered during rainy season was 3.17 ± 0.50 km-1 while that of the dry season was 4.63 ± 0.78 km-1. Although the dry season activities appeared to be higher, it was not significant; tcalc. = 1.762, ttab = 0.121, P = 0.05. The major threats to chimpanzees in its core distribution area in Oluwa Forest Reserve are agricultural activities, hunting and timber extraction. Eliminating these activities will improve upon Chimpanzees conservation in the reserve.

Watershed areas are vulnerable to risks of global and climatic changes due to the process of land use change and effects that had led to unprecedented challenges to both the human and aquatic environment. Vegetation of a location is one of the immediate indexes to test its vulnerability to risk of these changes. We carried out a woody vegetation assessment of three major tributaries (Arinta Waterfall, River Olua and River Ohoo) of River Owena in Ekiti State, Southwestern Nigeria, with the aim of providing information on the current state of its watershed. The assessment was carried out for three weeks using Point Center Quadrant Method due to the tributaries’ terrain along 300m on each tributary. Quickbird satellite imageries of the watersheds were obtained and subjected to unsupervised vegetation classification using ArcGIS 10 software to investigate their land cover/land uses. A total number of two hundred and forty (240) individual woody trees belonging to forty-eight (48) different species and twenty seven (27) families were observed. Out of the twenty seven (27) families recorded, family Leguminosae had the highest frequency of seventeen (17), it was followed closely by family Sterculiaceae which had frequency of thirteen (13). The woody tree species with the highest frequency was Theobroma cacao which occurred thirty six times (36). Four land cover/land uses - Settlement, Rock outcrop, Non-forested vegetation and Forested vegetation - were identified with 4.11%, 8.86%, 49.37%, 37.66% in Arinta Waterfall respectively, Settlement (9.18%), Non-forested vegetation (43.35%), Forested vegetation (47.47%) in River Olua and Settlement (3.16%), Non-forested vegetation (32.28%), Forested vegetation (64.56%) in River Ohoo. The threats to the vegetation around these tributaries and consequently to the watershed of Owena river are the serious encroachment from farming, logging and other human activities which had led to tapering of the primary forest around the river course.

Publication Title Woody Vegetation Status On Different Altitudinal Gradients Of An Ecotourism Destination: Arinta Waterfall, Ekiti State, Nigeria
Publication Authors Olaniyi, O. E., Ogunjemite, B. G., and Isiaka, M.T.
Year Published 2015
Altitude plays key roles in determining plant distribution and biodiversity patterns. The importance of
vegetation should not be undermined because it is one of the primary factors that determine the eligibility of
ecotourism sites. This study was undertaken at Arinta Waterfall, Ekiti State, Nigeria with an aim to determine
the woody species composition, structure and the influence of altitude (<440m, 440m – 480m, >480m) on the
floristic character of the study area. The Point Centered Quadrant method was employed. A total number of
thirty-six (36) different woody species belonging to twenty seven (27) families of woody trees were recorded.
Number of species, number of families, mean height and mean diameter at breast height were significantly
different among the three selected altitudes (P≤0.05). Richness, Shannon Wiener diversity index, Simpson
evenness index and mean tree canopy were not significantly different (P≥0.05). The vegetation of Arinta
waterfall still possesses some potential for conservation purposes. Logging activities and agricultural activities
are the major human threats at the site. Therefore, there is a need of re-orientation program for the host
communities in order to change their value system into imbibing biodiversity conservation and ecotourism
development. The supervising ministry on tourism and forestry in Ekiti State, Nigeria in charge of this site
should take immediate step to halt further degradation of the habitat cover.

Publication Title Ecotourism Development In Ikogosi Warmspring, Ekiti State, Nigeria: Implication On Woody Species Composition And Structure
Publication Authors Olaniyi, O.E. and Ogunjemite, B.G.
Year Published 2015

The high rate of infrastructural development in Ikogosi warmspring towards harnessing her enormous ecotourism potentials calls for a serious concern. The study aimed at identifying the past and present status of ecotourism facilities, determining and comparing the woody species composition and structure of the built- up and/or recreational areas and undeveloped areas of Ikogosi Warmspring, Nigeria. Interview method and field observation were used to identify the past and present status of infrastructural development. Quadrant method was employed to determine the phyto-sociological characteristics - woody tree species composition, diameter at breast height, height, abundance, richness and diversity. Significant level of vegetation indices was tested using T–test analysis. The result revealed 21 families of 49 different woody tree species with total frequency of 117 in the built- up and/or recreational areas while in the undeveloped areas, 25 families of 67 different woody tree species with total frequency of 203 were observed. Despite the slight reduction in richness and diversity of the woody tree species, eco- friendliness must be initiated in the planning process, so as to ensure environmental sustainability of the Warmspring’s vegetation through locating infrastructural development in less sensitive areas such as degraded land and fallow forest within the tourist site.

Adequate knowledge on the occurrence and spatial distribution of the tourism products in an ecosystem is very important toward promoting its sustainable use through ecotourism and its effective marketing for maximal patronage. This research aimed to create an attribute database of ecotourism resources and produce an ecotourism resource map of T.A. Afolayan Wildlife Park, Ondo State, Nigeria. Information on the ecotourism resources of the study area were obtained through secondary data collection method and field survey. Spatial data on ecotourism resources were collected using a hand-held Global Positioning System and uploaded into QuantumGIS software environment. Thirty woody species belonging to twenty four families and twenty species of birds belonging to twelve families were identified. Eighteen fauna species belonging to twelve families were managed under insitu and exsitu management strategies. Fauna species with conservation status of vulnerable (Cercocebus torquatus, Psittacus erithacus and Geochelone sulcata) and endangered (Balearica regulorum) were observed. Also, ten human-made ecotourism facilities and three nature trails with a total length (386.84m) were identified and pictorially represented. However, it will be highly imperative for more flagship and endangered fauna species to be stocked, and the picnic sites to be situated far away from the pens in order to mitigate the negative impacts of tourists visitations on the animals.
