“…The result of the study revealed that plot A is the richest, having highest value of species richness when compared with other plots, meaning that plot A is less disturbed or impacted when compared with other plots. This is in agreement with Offiong et al (2011) who observed that vegetation in the less impacted site was richer, more diverse and heterogeneous than vegetation in impacted site. However, the general reduction in species richness observed in most of the plots is an indication that the area was recently disturbed and thus typical of secondary rain forest after disturbance.…”

This study assessed the floristic composition, soil properties and the soil seedbank of the vegetation around the Iron smelting factory. This was with a view to determining the functional role played by soil chemical composition and the seed bank in the modifications of vegetation patterns. Five 100 m × 5 m plots were selected from the study site; vegetation, soil seed bank and some soil chemical parameters were assessed. One-way Analysis of Variance and Duncan multiple range tests were employed for data analysis. The results showed that the soil samples collected were slightly basic (or neutral) with the total Nitrogen in all the five plots ranged from 0.22 to 0.33%. There was a little contribution by woody species to the floristic composition of both the standing vegetation and soil seed bank. There was very low similarity (10.6%-28.57%) between the standing vegetation and the soil seed bank species composition in the study site. The results of seedling emergence showed that herbaceous species dominated the soil seed bank compared to other life forms. Our result revealed a shift between seed-bank and vegetation composition which could be a consequence of the soil chemical properties and also as a result of different level of disturbance occurring due to the citing of industry in the area.

Biodiversity Status of the Immediate Vicinity of an Iron and Steel Recycling Factory in Ile-Ife, South-Western Nigeria

Floristic composition of vegetation communities of 27 plots established along a line transect in the four major directions was investigated in the vicinity of an Iron and Steel factory in Ile-Ife, Nigeria. The aim of the study was to document the plant species composition (biodiversity) of the plant communities found within the 350 m perimeter of the facility in the study area, which will serve as a reference data, as there was no reported study for the area prior to the establishment of the factory. Plant species were identified to species level in a 10 x 10 m plot and the occurrence of each species was described in semi-quantitative terms. The vegetation is heterogeneous in nature having 31 species of tree saplings and climbers, 26 of shrubs, 15 of herbaceous plants and 4 of grasses. These 107 plant species belong to forty six (46) plant families. The dominant families included Apocynaceae and Papilionaceae (9 species), Sapindaceae (8 species), Euphorbiaceae (6 species), Asteraceae, Cucurbitaceae, Malvaceae, Poaceae, Sterculiaceae and Verbenaceae (4 species). Among the diverse species recorded, Chromolaena odorata formed a ticket in almost all the plots. Other common species included Albizia zygia, Alchornea laxiflora, Aspilia africana, Cnestis ferruginea, Combretum sp., Icacina tricantha, Ipomoea involucrata, Momordica foetida, Panicum maximum, Paullinia pinnata, Simicrata welwitschii and Vigna gracilis. The index of similarity of the plots ranged from 6.1 to 71.8%. The potential and vulnerability of the species were highlighted. Adherence to and enforcement of environmental regulations was recommended for preservation of the native species.

“…In addition, Offiong, Offiong and Ekpe (2014) focused on the socio-economic characteristics of property owners who comply with building regulations in Calabar, Nigeria. The study concluded that the socio-economic characteristics of property owners or residents, in particular income and educational status, determine the extent of adherence to building regulations in the study area.…”

This paper examines the socioeconomic characteristics of residents and their level of awareness of development control regulations in gated communities (GCs) of Ibadan Municipality, Nigeria. Multistage sampling technique was employed in selecting 268 residential buildings from the identified 23 gated communities in the five (5) local government areas (LGAs) of Ibadan Municipality. Random sampling technique was employed in selection one gated community in each of the situated housing schemes of the LGAs of Ibadan Municipality. Findings revealed that socioeconomic characteristics of the people is a determinant in evaluating residents' awareness and compliance with development control issues. This is substantiated with chi-square and ANOVA test result that revealed a significant relationship between marital status and their level of awareness of development control regulations with χ 2 = 0.630 and significant at p ≤ 0.05 level as well as income of residents and level of awareness with [F (238, 2) = 2.286 and significant at p = 0.104 < 0.05 levels. The study further revealed that the levels of residents' awareness with the identified elements of physical planning regulations and practices across the three GCs were a little above average. The paper concluded that efforts should be put in place to improve or enhance the socioeconomic characteristics of the residents which will invariably improve their level of awareness of development control regulations and will surely impact on their compliance.
