The remnant floral diversity of a naturally reclaimed area proximal to an abandoned mine was assessed. The coal mine site, the Incident zone (IZ) and an unsullied site, the Control zone (CZ), were sampled. Using a 5 m2 quadrat, the floristic composition was determined by the occurrence, distribution analysis, and species diversity indices. The study revealed a degraded vegetation type and recorded a total of 60 species, 53 genera and 27 families. Both the IZ and CZ shared 26.67 % species similarities, while 36.67 % are unique to each. Five species were dominant (Ageratum conyzoides, Panicum maximum, Calopogonium mucunoides, Chromolaena odorata). While the dominant genera vary between IZ (Borreria, Dioscorea, Ipomoea and Phyllanthus) and CZ (Desmodium, Euphorbia and Ipomoea), Asteraceae and Poaceae were the dominant families in both zones. Forbs were the most dominant life forms in both zones; Cyclosorus sp. and Adiantum sp. were only found on the IZ, whereas, Kyllinga erecta and Mariscus alternifolius were exclusive to the CZ. Our results reflect that species composition and vegetation paradigm in the study area could be influenced by coal mining, farming, infrastructural installations and climate. Hence, we suggest future studies to investigate how the species adapt to the environment. Although most of the species encountered belonged to lower-risk conservation, the conservation of the species to this area is imperative.

尼日利亚埃努古亚烟煤堆场的花卉分布

评估了靠近废弃矿山的自然开垦区的残留花卉多样性。对煤矿现场,事故区域(IZ)和未受污染的现场,控制区域(CZ)进行了采样。使用面积为5平方米的正方形,通过发生,分布分析和物种多样性指数确定植物区系组成。该研究揭示了退化的植被类型,并记录了总共60种,53属和27个科。IZ和CZ都具有26.67%的物种相似性,而36.67%的物种相似性是唯一的。五种为优势种(香叶A香,最大山茱,、 Colopogonium mucunoides,Chromolaena odorata)。虽然优势属在IZ(Borreria,Dioscorea,Ipomoea和Phyllanthus)和CZ(Desmodium,Euphorbia和Ipomoea)之间有所不同,但菊科和禾本科是这两个区域的优势科。在这两个区域中,Forbs是最主要的生命形式。Cyclosorus sp。和铁线虫 仅在IZ上发现,而Kyllinga erecta和Mariscus alternifolius仅在CZ上发现。我们的结果表明,研究区的物种组成和植被范式可能会受到煤矿开采,农业,基础设施和气候的影响。因此,我们建议进行进一步的研究,以调查该物种如何适应环境。尽管遇到的大多数物种属于低风险的保护区,但必须在该地区保护该物种。我们的结果表明,研究区的物种组成和植被范式可能会受到煤矿开采,农业,基础设施和气候的影响。因此,我们建议进行进一步的研究,以调查该物种如何适应环境。尽管遇到的大多数物种属于低风险的保护区,但必须在该地区保护该物种。我们的结果表明,研究区的物种组成和植被范式可能会受到煤矿开采,农业,基础设施和气候的影响。因此,我们建议进行进一步的研究,以调查该物种如何适应环境。尽管遇到的大多数物种属于低风险的保护区,但必须在该地区保护该物种。
