Abstract: The study area is located in the coastal region of northwestern libya, west of khoms city. This region is
characterized by a temperate climate with an average annual precipitation of 17 mm. Cement emissions are proven
to have damaging impacts on different plant species. This study focuses on the impact of stack emissions from
mergheb cement factory on the abundance, frequency, density and number of species at each site surrounding the
factory under the effect of wind direction. The surrounding areas are subdivided into sites to assess plant species
variability and their growth. It is concluded that there is a gradual reduction in density and vegetation cover towards
the cement factory. Field observations revealed that the biodiversity in the east of cement factory is greater than that
in the southwards.
