3.4.5.1 Population Density
Population pressure is the social factors that might affects conservation areas. A high population number are would give high pressure to conservation
areas. During field work data updated, indicated that 12.716 peoples are lived within national park areas. All six villages covered within national park are
categorized as rural villages. Statistics data processed has produced a population density map for six villages of area study. Furthermore analysis is the density
population attributes have been normalized within new values range from 0-1 Low-High. Normalized weight values thence to re-evaluate in classes within
scale 1 to 5 by 1 based on ArcMap Natural Break Jenks. Classes generated are based on natural groupings inherent in the data. ArcMap identifies break points by
picking the class breaks that best group similar values and maximize the differences between classes. The features are divided into classes whose
boundaries are set where there are relatively big jumps in the data values. Population density in Com is 29.51personkm

and placed both villages at ‘higher’ and ‘high’ pressure to conservation areas. It occurred because in the areas with high people would
require more land expansion for agriculture. Lore I and Tutuala, both villages have rank as village with ‘medium’ pressure to conservation areas. Mehara and
Bauro are villages with ‘lower’ and ‘low’ population pressure to conservation areas. Average population density within national park area is 20.92personkm
