The increasing destruction of the Zagros forests ecosystem in recent years has doubled the need for valuation studies in this area. The progressive development of economic valuations methods in recent decade enables the application of the concept of payments for ecosystem services (PES) in order to conservation of forest biodiversity and habitate functions. In this study, the habitat value of North Zagros forests in Sarvabad basin of Kurdistan province was estimated through conditional valuation method (CVM) and logit model. For this purpose, 260 willingness to pay questionnaires based on Cochran's formula were completed. The internal consistency of the questionnaire items and the reliability of the questionnaires were confirmed by Cronbach's alpha (77.6) and the validity of the items and questions was also judged by a group of related professors. The willingness to pay for habitat protection function was calculated through the logit regression model and using the median willingness to pay method. The expected amount of willingness to pay for the protection of the habitat value of the study area in this study was equal to 52825.8 Rials. Also, the annual value of habitat and wildlife protection of Sarvabad watershed was equal to 121254.6 million Rials and the annual conservation and habitat value of the whole basin (per hectare) was equal to 6.58 million Rials. The results confirms that people who have already visited the area, are members of environmental organizations, or have an environmental orientation are significantly more likely to accept a willingness to pay than those who do not.

Since there are different statistics on the area, distribution, and density of Zagros forests, continuous monitoring and evaluation of these forests are facing implementation problems. The available statistics and information from Zagros forests are not effective in the management decisions of these forests due to many reasons such as their preparation in the traditional way or their oldness. In this research, a high-accuracy map of canopy density and distribution of Zagros forests as well as the determination of other land uses have been prepared using Sentinel-2 images of 2019 in the south of West Azarbaijan province. The image classifications were performed with the supervised method and ML and SVM algorithms in the ENVI 5.3 software environment. The Bing and Google Earth images were used to prepare the ground truth map to evaluate the accuracy of the output maps. In this research, the five non-forest land uses including ranges, gardens, agriculture, water sources, and barren and residential lands were classified. The results showed that the maximum likelihood algorithm with an overall accuracy of 87.3% and a kappa coefficient of 0.74 was the most accurate in preparing the canopy density map. The available statistics showed that the state of forest cover in the province is not in a favorable condition and the area of Zagros forest in the province is equal to 60200.55 ha, which is equivalent to about 90% of the updated statistics of the forests, rangelands, and watershed management organization of the country (67235,91 ha) in 2020. It can be stated that Sentinel-2 data has an acceptable efficiency in terms of accuracy and cost for preparing the canopy density and distribution map of forest areas and preparing the land use map.
