Private Participation in Forest Plantation Development in Nigeria
(2001) Jimoh, S. O.; Bada, S. O.
"Nigeria’s endowment of natural forest was so vast that it was thought to be inexhaustible. Today the resource base has been badly eroded. Only about 5% of the nation's land area is under forest cover. The current situation is that the nation can no longer meet its domestic wood need and has thus have to rely on wood importation to supplement domestic production. Though series of efforts have been made to bridge the gap via plantation establishment; the results of these efforts have not been good enough to achieve the objective. This paper traces the history of forest plantation establishment in Nigeria form the early part of the 19th century to date. It is observed that the level of private participation in forestry development in the country is still very low. This is contrary to the contemporary global trend in which private participation in plantation development is growing rapidly. It is suggested that public enlightenment; legislative reforms, provision of technical and financial assistance; funding of relevant research targeted at the private sector's needs and prevision of clear definition of property rights be embarked upon by the government in order to stimulate the interest of private investors."
Rate of decomposition of leaflitter in an age series gmelina arborea robx plantation in a Nigerian lowland rain forest
(2011) Ogunyebi, A. L.; Omole, A. O.; Bada, S. O.
The study was carried out to investigate the rate of decomposition of Gmelina arborea Robx leaflitter in an age series in Gmelina plantation in shasa forest reserve in a Nigerian low land Forest. Rate of decomposition of Gmelina leaf litter was determined using litter bag technique and mass balance analysis to quantify the rate of leaf litter decay in the stands. Data collected were analyzed using descriptive and inferential statistics at 0.05 level of significance. Nitrogen(N) and Phosphorus(P) were significantly different among the three stand ages (p <0.05). A fast decomposing rate of the leaves relatively increases P after mineralization. Nitrogen, Phosphorus, Calcium and Magnesium decreased significantly with soil depth, while Potassium and PH showed no significant association with soil depth. There was a decrease in sand and silt percentages with increasing depth. Clay content however increased with increasing soil depth (P<0.05). Decomposition constant (K) of 0.08 was found for the leaves, with a turnover time of 3 to 6 months. Macro nutrients concentration in the leaf litter decrease in the order Ca> N> Mg> P> K. The study revealed that the rate of decomposition is very fast in the studied site.
Seasonal variation in litter fall an age series gmelinaarborea plantation in a Nigerian rainforest
(2013-01) Ogunyebi, A. L.; Omole, A. O.; Bada, S. O.
Monthly variation in litterfall of Gmelinaarborea stands aged 28, 29, and 30 years were studied for 13 months in 2005 - 2006 with litter traps in three 20m x 20m plots randomly selected in Gmelinaarborea stands in Shasha Forest Reserve (SFR),Osun State, Nigeria. Monthly collections of litter fractions per stands were sorted into leaves, twigs, reproductive structures and others. Litters according to fractions per stand per month were oven dried at 80°C for 48 hours. Samples were created for chemical analysis. Data collected were analyzed using descriptive statistics and inferential at 0.05 level of significance. Litterfall (especially leaf fall) occurred throughout the period of collection (13 months) in the stands (S). The peak of total litter fall was recorded in October 2005 in S1(18.2%) while peaks were recorded in September of same year in S2 (11.21%)and S3 (13.67%). The analysis of variance to determine interaction effect between fall of the litter fractions and age of the stands did not show any significant differences. Leaves constituted the bulk of litter fall across the three stands. The percentage of leaf litter to the total litter per hectare in stand ages 28, 29 and 30 years were 41.32, 34.19 and 24.48% respectively, while the contribution of unidentified litter thrash was highly insignificant.
