Moist Forest Research Station, Benin City. Edo State.

Head of Station:Dr. Idumah Felix. O

Brief information about the Outstation

  Forestry Research activities in the Moist Forest zone of Nigeria predated the enactment of this Research Station in Saponba in the early 1970s. The early researches were carried out at natural forests within designated investigation plots at Uronigbe and Okomu Forest Reserves as well as the Strict Nature Reserve (SNR) also located in Uronigbe Forest Reserve. The establishment of the Kennedy Field Laboratory in 1929 was the first attempt at establishing a forest plantation in the zone. The Research Station, then, Saponba Forest Reserve, was located some 49km away from Benin-City in the present Orhionwon Local Government Area of Edo state. Presently the office is positioned at the Ogba Forest Reserve situated along Utagban road, in Oredo Local Government Area of Benin-City. This move was as a result of incessant harassment of the staff of the Station by illegal timber poachers in Saponba in the late 1990s. Moist Forest Research Station (MFRS), Benin City Edo State, Nigeria is located within latitude 6o 32 N and longitude 5o 58 E; 99m above sea level. It has a mean annual temperature range of 27o C and 32o and the mean annual rainfall is 2078mm. It is situated on a total land area of 260Ha with substations spread across the state. These include: Saponba Forest Reserve; 1040Ha, Agbede substation; 260Ha, Okhuesan; 260Ha, Uzairue; 260Ha, Urhonigbe; 780Ha, Okomu; 520Ha, Iguobazua; 260Ha and Ohosun; 260Ha. The Station as presently constituted has a thriving nursery consisting of various indigenous and exotic species for plantation establishment at Saponba, Agbede and other substations. Other Units include Oil Palm, Vegetative Propagation, Snailery and Poultry.

Over the years, hundreds of thousands of tree seedlings have been raised. These include: Tectona grandis, Gmelina arborea, Khaya spp., Irvingia spp., Terminalia spp., Mansonia altissima, Moringa oleifera, Pycnanthus angolensis, Pterocarpus angolensis, Xylopia aethiopica, Allanblackia floribunda, Monodora myristica, Tamarindus indica, Eucalyptus camaldulensis, Elaeis guinensis, Albizia lebbeck, Gambeya albida; just to mention a few.

                                    

    Plantation Establishment MFRS

    Plantation Establishment has been rigorously involved in the establishment of plantations of exotic and indigenous species across Edo State. The Evbousa and FRIN Afforestation Projects at Sakpoba are two of such afforestation efforts. The Evbousa Community Farm is a Taungya System that enlists the services of local farmers, within the community, in the planting and maintenance of tree seedlings supplied by the station. They plant and nurture their agricultural crops alongside the tree seedlings on plots of land allocated by the station.

    Phytochemical Screening, and Medicinal Potentials of the Bark of Dacryodes edulis

    The objective of this study was to identify and quantify the phytochemicals and examine the medicinal benefits of the bark of Dacryodes edulis tree species. Chemical tests were conducted on an aqueous extract of the bark sample by using standard methods. Qualitative screening identified Alkaloids, Phenols, flavenoids, tannins, cardiac glycosides, saponins, Anthraquinones and steriods. The phytochemical screening of the bark of Dacryodes edulis revealed that alkaloids(18.13 mg/kg), Phenolic compounds (22.01 mg/kg), Flavenoids (60.91 mg/kg), Tannins (18.16 mg/kg),Saponins (3.16 mg/kg), Anthraquinones (12.16 mg/kg), Cardiac glycosides (0.81 mg/kg) and steroids (0.91 mg/kg) were significantly present in the sample. The presence of these phytochemicals gives credence to the medicinal benefits that the bark of this plant has been used for in the past years.

    Determination of Proximate and Mineral Elements Compositions in the Bark of Dacryodes edulis (G.Don) H.J. Lam

    The major objective of this study was to evaluate the proximate, mineral composition, total antioxidant capacity and content of phenol (total) of the bark of D. edulis (G.Don) H.J. Lam. Proximate study revealed that the bark is adequate in nutrients and minerals. Macro nutrient like protein Carbohydrates was determined with a content level of 58?0.16mg/kg. Other macro nutrients were also relatively high in content level. While crude Protein had a content level of 61.73?0.11mg/kg, crude Lipid had a content level of 48.56?0.20mg/kg. Proximate analysis for crude Fibre, Vitamin C, Ash, and Moisture also revealed their contents levels to be 61.66?0.92mg/kg, 24.01?0.16mg/kg, 52.37?0.38mg/kg and 14.56?0.18mg/kg, respectively. The existence of essential minerals and their contents levels analysed showed that Dacryodes edulis contains sodium (Na; 7.20?0.04) mg/kg, potassium (K; 2.57?0.25)mg/kg and Iron (Fe; 17.76?0.02)mg/kg, calcium (Ca; 83.24?0.89)mg/kg, Zinc (Zn; 3.65?0.08)mg/kg, and manganese (Mn; 241.28?)mg/kg, respectively, values range that are non-lethal, therapeutic and idea for the maintenance of good health except for Manganese that was on the very high side. Dacryodes edulis bark w as found to be also very rich in anti-oxidants and phenols, with total anti-oxidant capacity of 103.02?0.62mgVce and phenol (total) content of 112.95 ? 0.56GAE100-1 respectively. This showed that it is nutritionally adequate in proximate compounds of Carbohydrates, Protein, Lipids and Vitamin C, and not lacking in essential food fibre and moisture as well as, essential minerals of sodium, potassium, iron, calcium, and zinc in contents levels needed for a healthy life, except manganese, with a very high content level, which calls for a control use of any decoction from the bark of Dacryodes edulis (G.Don) H.J. Lam

    Influence of Cutting Position and Clonal Variation on Rooting of Dacryodes edulis

    The main objective was to propagate the species vegetatively using leafy stem cuttings. Hence to investigate the effect of cuttings position on the rooting of the species and determine the effect of clonal variation on the rooting ability of the species. It was discovered that the clonal variation and cutting position significantly affected the root length of cuttings. None of the tested factors or interaction between them had significant effect on root numbers and rooting percentage.

    Breaking Seed Dormancy in Garcinia kola Using the Heat Method Approach

    The objective of this research work was to investigate the effect of different heat treatments on the early germination of the species. Using black and transparent polybags, de-coated seeds of Garcinia kola were subjected to varying temperatures. Misting was done weekly and data of germinated seeds collected every two weeks. At the termination of the experiment, about 85% of seeds from black bags germinated while 52% germinated from transparent bags. This was a great success considering the seed dormancy problem associated with the species.

    Vegetative Propagation of Nauclea diderrichii Using Cuttings

    A 2x2 Factorial experiment was arranged in a Completely Randomized Design. The factors were cutting age (6 months and above 1 year) and propagation media (river sand and decomposed saw dust). Four (4) treatment combinations were derived with 10 cuttings assigned to each. The treatments were replicated 3 times; resulting in 120 cuttings. Data was collected fortnightly and analyzed. Result showed that cutting age had significant effect on rooting with age 6 months cuttings having a higher percentage of rooted cuttings (80%) while cuttings from stump of over one (1) year had rooted cuttings of up to (55%). Propagation media had no significant difference in rooting of cuttings.

    Phytoremediating Potentials of Jatropha curcas (L.) Seedlings Grown on Spent Oil Polluted Soil.

    An assessment on the effect of spent oil polluted soil on the growth rate of Jatropha curcas seedlings was carried out. Investigation on the potentials of Jatropha curcas in the phytoremediation of spent oil polluted soil with special focus on Total Petroleum Hydrocarbon (TPH) and Heavy Metal composition of the soil was done. There was a general significant reduction in heavy metal composition of the phytoremediated soil at the end of the investigation. Total Petroleum Hydrocarbon (TPH) degradation was highest in phytoremediated soil as compared to the non-remediated soil. The Jatropha curcas seedlings were able to withstand the phytotoxicity effect of the spent oil contaminants in the soil.

    Analytical Study of Climatic Trend in the Niger-Delta Region of Nigeria.

    Mean monthly temperature (minimum and maximum) and rainfall data for Warri, Ondo, Port Harcourt, Benin City and Calabar from (1951 to 2012) were collected and collated from the Nigeria Meteorological Agency (NIMET), Lagos. The climatic data used covered an average of sixty two (62) years. The annual and decadal trends of the climatic parameters were analyzed using simple bivariate linear regression analysis and second order polynomial. The trend analysis of rainfall, temperature and rain days showed a non-significant decrease for rainfall in Warri and Port Harcourt and a non-significant increase for Ondo, Benin City and Calabar. The trend also indicated a statistically significant upward trend for minimum, maximum and annual mean temperature in the five (5) stations investigated.

    Assessment of Some Biological and Physicochemical Properties of Soil Under Tectonia grandis Plantation in Sakpoba

    The research was to determine the biological and physicochemical properties of soil under Teak plantation and fallowed plots around the plantation. Soil samples were collected with a soil augar from six points located randomly within a 30m square quadrat at predetermined depths of 0/60cm. Results showed that Teak litter accumulation and decomposition greatly influence soil development and availability of soil microorganisms. The increase in clay and silt content of the soil in Teak plantation helps to improve the soil structure and also enhance the buildup of essential nutrient. Soil from Teak plantation helps to reduce soil salinity through reduction in sodium content. It also showed that Teak can maintain soil fertility by protecting the soil from harsh climatic conditions.
