The spatial analysis of leopard cat scats and the grid for the Ecological and Natural Map in Korea

Abstract

We revisited the confirmation points of the leopard cat scats surveyed in 2009 for forests around Gyejoksan. We analyzed the relationship between the total length of the walk route and the wild mammal trails, and the rate of rediscovery of the leopard cat scats within the Ecological and Natural Map grid. First, in the correlation analysis between the total length of the walk survey route and the number of mammal trails, we confirmed that the longer the walk survey route, the higher the number of mammal trails. Second, as a result of analyzing the rediscovery rate for grids of confirmed scats in 2009 and 2015, the average rediscovery rate was 0.57 in 20 grids. However, when the size of the existing grid was tripled, we confirmed that the rediscovery rate in the grid increased about 1.7 times with an average of 0.98. In addition, it was confirmed that there was no grid that the leopard cat scats had not been rediscovered at the 750-meter grid. From these results, determination of the habitat based on the scat point should be improved because the excretion zone of the leopard cat is wider than the 250-meter grid in the Ecological and Natural Map.
