Assessing the Wild Mammals Status Affected by HumanWastes, Based on the FieldWorks and MCDM Analysis

Background: Waste has negative impacts on animal species and their habitats. Objectives: This study was aimed to evaluate the wild mammals status affected by human wastes. Methods: The study was carried out in villages of Oshtorankooh protected area of Lorestan province in 2019. The quality and quantity of waste was measured by sampling and measuring waste in 42 villages. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) in combination with the Fuzzy Analytic Hierarchy Process (FAHP) was used to evaluate impacts. Results: The waste generation rate and density were 555 g/day and 412 kg/m3, respectively. Also, the results of ranking showed that Canis lupus, Vulpes vulpes, and Hyaena hyaena were ranked with the highest scores of 2.260, 1.958, and 1.948, respectively, and these species were more affected. Conclusions: It is necessary to consider waste effects on animal species, and according to the results of TOPSIS and impacts assessment, the presented method has shown good performance.
