The desire to shore up the shortfall in protein supply, the increased awareness of the importance of cholesterol free animal protein, like guineafowl, and the need to conserve their wild genes, have necessitated studies on improved captive breeding of feral helmeted guineafowl. Hence, this study was aimed at determining the effects of ecological zones and storage systems on the guineafowl eggs. Guineafowl eggs (n=214), were collected from identified and monitored-nests within the Kainji Lake National Park (KLNP) and Old Oyo National Park (OONP). Out of 91 eggs collected from KLNP, 32 and 38 were stored at room temperature (RT-21-25°C) and refrigerator (RF-17-20°C), respectively for five days prior to incubation while 21 eggs were not stored (NS-27-29°C), and out of 123 collected from OONP, 70 and 19 were stored for five days prior to incubation at (RT-21-25°C) and (RF-17-20°C), respectively while 34 eggs were (NS- 27-29°C). Prior to incubation, eggs were weighed, the height and width were measured. The process was repeated after incubation for unhatched eggs. Candling was done three days before hatching at day 29 of egg incubation. Embryo status of unhatched eggs was determined by cracking the eggs. Descriptive and inferential statistics were used to analyse the data. The NS eggs from Kainji (7.60%) and Oyo (2.01%) had the lowest percentage shrinkage in weight across the three storage systems. The order was reversed in height with RF eggs from Kainji (0.96%) and Oyo (0.46%) having lowest. The least shrinkage in width of eggs from Oyo was recorded in the RF eggs (0.00%) and in NS (0.59%) from Kainji. Eggs candling showed that presumed fertile (opaque) was highest (69.10%) in NS eggs followed by RT (45.00%). There was no significant difference (p>0.05) between the hatchability of eggs from the two parks though hatchability (7.60%) of Kainji eggs was higher than those of Oyo (7.40%). Further check on fertilization after incubation showed that RT (37.50%) eggs from Kainji were fertilized but were unable to hatch alive so also was RF eggs (21.10%). The study showed that the eggs sizes vary with ecozones while size of the eggs and storage systems affects hatchability and survival of feral helmeted guineafowl eggs in captivity.

The study assessed the relative abundance and vegetation structure of African buffalo (Syncerus caffer) including plant parameters: frequency, diameter at breast height (dbh), tree height, diversity, evenness, richness, Margalef, dominance in Kainji Lake National Park. Point – Centered Quarter method was used for woody species enumeration. A total of twenty-eight (28) randomly sampled plots of 150m by 100m given 112 points per plot were established in the study area. The abundance and distribution, tree frequencies, heights, dbh and plant biodiversity indices were calculated using the Paleontological Statistics Software (PAST) for scientific data analysis. The results revealed that relative abundance of African buffalo in both morning and evening of dry and wet seasons in various habitats of the Park were 13.33 ± 4.41 and 11.33 ± 4.40 respectively. The study showed the highest mean value of 21.75 ± 6.94 representing 87 individuals in dry season compared to wet season with mean value of 15.25 ± 5.11 representing 61 individuals. A total of 91 woody plant species and 29 tree families were recorded in African buffalo habitats representing 80, 77, 68 and 59 tree species respectively. The highest average girth size of tree species was class between >10cm -50cm with 59.14 ± 4.06 and the highest mean tree height was height class of >3 - 10m with 91.43 ± 5.44. There were significant differences at (p<0.05) between the values of dbh, tree height, diversity, richness and evenness of plant species recorded in different habitats studied in the Park.

Assessment of Environmental and Recreation Facility Maintenance was carried out in Kainji Lake National Park. Questionnaire method of data collection was employed to collect the data needed. Purposive and simple random techniques were adopted to sample respondents in the study area. One hundred questionnaires were designed and administered. The data collected were analyzed through simple percentage and presented in table and charts. However, the results showed that recreation facilities are 99% present, while swimming pool is 65% functional. The study showed that visitors came there three times in a week indicating 44% of the respondents while on maintenance of the park environment and the facilities indicated 94% and 88% of the respondents respectively. The study further recommended the followings facilities basketball pitch. Hockey game, volley ball and well-constructed swimming pool.
