Spatial Distribution of Plant Species Richness: Context Satchari National Park, Sylhet, Bangladesh

The number of different species varies by place to place. Spatial pattern of species richness varied with the different spatial and thats why location mapping is necessary. The aim of the study is to map out the spatial pattern of the species richness of a national park as to understand about the conservation of biodiversity or species richness along with different spatial pattern which helps to know how trees, herbs and shrubs are associated using ordinary kriging and regression kriging method and comparing methods explain better variation. In regression kriging elevation (m) is used as a week predictor and interpolation finds that species richness is higher in north zone of the study area. The amount of variation in ordinary kriging is 29.45 per cent and in regression kriging 25.78 per cent and the change in comparison of both ordinary kriging and regression kriging method is very low. The findings of the study support and contrast that species richness higher in the north zone of the study area and the variation of ordinary kriging and regression kriging interpolation is not strong.
