“…The species richness of a forest ecosystem depends on the number of species per unit area. The situation where there are more species per unit area, the species richness tends to be high (Eludoyin et al, 2017). The species richness values of 82 tree species/ha for the unmined area and 7 tree species/ha for the mined area were lower as compared to 552 tree species/ha obtained in a tropical forest in Kade in Ghana (Hall & Swaine, 1981) and 93 tree species/ha observed in a tropical forest in Tanzania (Kacholi, 2014).…”

“…According to Kothandaraman & Sundarapandian (2017), the Euphorbiaceae was the dominant plant family in two forest areas in the tropical deciduous forest of Kanyakumari Wildlife Santuary in India. The Papilionaceae, Moraceae, Sterculiaceae and Sapindaceae were listed as the dominant plant families in a tropical forest ecosystem in south-western Nigeria (Eludoyin, Ojo, Ojo, & Awotoye, 2017).…”

“…The anthropogenic disturbances as a result of small-scale mining probably led to the destruction of canopies and creation of gaps in the mined area leading to the preponderance of herbaceous species with relatively higher densities and frequencies ( Table 8). The floristic richness of species in a forest zone could be influenced by the geographical location of the area, favourable climatic conditions and the level of anthropogenic disturbances (Eludoyin et al, 2017;Laurin et al, 2013).…”

The impacts of small-scale mining on the vegetal cover as well the livelihoods of communities in mined areas in developing countries such as Ghana are far-reaching. This study assessed the impacts of small-scale mining on flora of conservation and economic significance through quantification of species richness, and species diversity. Mined and unmined sites were chosen in the Dunkwa East Municipality of Ghana. Five belt transects each (200m × 200m) were constructed in both sites. Each belt transect was divided into 100 quadrats (20m × 20m) and plant species in each of the quadrat were identified in the field and or the herbarium of the School of Biological Sciences, University of Cape Coast. One hundred and fifty seven species distributed in 140 genera and 54 families were identified in the mined area whilst the 209 species identified in the unmined area were in 185 genera and 73 families. Plant families Euphorbiaceae, Rubiaceae and Asteraceae were more diverse whilst Asteraceae, Poaceae and Euphorbiaceae were dominant in the unmined area. In the mined area, however, Poaceae, Euphorbiaceae and Asteraceae were more diverse. Pteridium aquilinum, Tridax procumbens and Waltheria indica in the unmined area and Chromolaena odorata, Sporobolus pyramidalis and Euphorbia hirta in the mined area were the dominant species. Small-scale miming activities have caused reduction in species diversity, richness and economic and commercial values in the area. Higher disturbance of the flora has resulted in more secondary species in the mined area. Restoration is required in the study area.

“…Thus, mining activities might have a highly negative impact on the vegetation of this area in the near future, particularly in the northeastern part where these activities are intense. Mining activities are considered responsible for the deterioration of micro and macro organisms and vegetation in several countries [44].…”

Saudi Arabia is located within an arid to semi-arid region, however, it is a biological diverse area, because species have adapted to the adverse ecological circumstances. One of the most important habitats in Saudi Arabia is the Mahazat Alsayd natural reserve. Understanding changes in vegetation cover over time is important for studying the habitats present in the reserve, and for analyzing the availability of animal fodder, as well as the extent of vegetation regeneration. Using remote sensing data and field observations, we detected that the vegetation coverage of Mahazat Alsayd decreased by 80% from 1995 to 2015. Multiple factors are currently affecting the structure of the plant and animal communities within the reserve. Such factors include ecological changes and human activities. These factors might lead to the extinction of some plant and/or animal species in the near future, either directly or indirectly. Thus, a comprehensive management plan must be implemented in the reserve as soon as possible to maintain and recover vegetation to provide sufficient animal feed, facilitating the sustainable conservation of animals and plants within the reserve. The vegetation cover assessment presented here provides an important source of information for conservation planning.

“…Mining is the main economic activity of many developing countries. Mining was among the major source of export in Nigeria before 1970 (Eludoyin et al 2017). The overdependent on oil resources have intensified artisanal mining practice in the country due to lack of government will, intervention and implementation of available regulations.…”
