Investigation of the efficiency of MaxEnt, topsis and invest models on site suitability and decline potential of Persian oak forests in Zagros, Iran (Ilam Province)

Background: Over the last decade, a significant area of Zagros forests, especially in Ilam Province, west Iran, has been affected by phenomenon oak decline. The most basic item for fighting decline these forests is to know site suitability, parameters affecting it, determining criteria and preparing map potential forests. In this study, efficiency Maxent on suitability Dalab Bankol important P.Oak was investigated TOPSIS. integrated valuation ecosystem services tradeoffs (InVEST) used prepare zoning site. Validation maps done with receiver operating characteristic curve (ROC) field visits. Results: results showed that pc-forest, distance from rivers temperature are distribution P.Oak. addition, many parts both sites were found lack suitability. TOPSIS socio-economic criteria. Conclusions: Decline much higher pressure caused stressful 6 general stresses land use change, grazing, pests, charcoal disease, fires tourism two sites. shown better condition terms potential. reason operation conservation management obtained show methods.
