Effects of Aleppo Pine (Pinus halepensis Mill) Plantation on Plant Biodiversity in the High......

The impact of Aleppo Pine monoculture in the Sada high plains on biodiversity, richness, and rate of indigenous flora is the focus of our research. 30 floristic surveys were conducted to assess biodiversity indices both inside and outside of the woody areas for this aim. The TWINSPAN approach divided ecological species into two groups; the similarity research revealed a clear distinction between the groups, and the total value of ANOSIM-R was 0.99 (P.001). In non-wooded locations, the average species richness and the Shanoon index are 2.063 and 2.23, respectively, greater than in wooded sites. The survey revealed the existence of 98 different plant species. There are 14 imperilled, endemic, or rare species among them. Reforestation has resulted in the extinction of 27 species, 11 of which are threatened, endemic, or uncommon. As a result, it is advised that biodiversity be considered in afforestation operations in order to preserve natural habitats and reduce native species loss.
