Background and Objectives: The value of non-market for environmental goods such as habitat protection and perspectives are important. The aim of this study was to evaluate the protective Khaeiz protected area is by use of CONTINGENT VALUATION METHOD. METHOD: In this study the effect of different explanatory variables on respondents' willingness to pay for the Protection of logit regression model was used. The required data from 196 completed questionnaires were collected. Findings: 71% of respondents expressed a willingness to contribute to the protection of the region. Results of logit model estimation showed that the index trend of environmental variables, accountability, financial, environmental and offered membership in the organization are significant. The results showed that the expected value of the willingness to pay was 23948/5 million Rials. The monthly value of protecting the region against 18861/28 million rials respectively. The protective value against was determined 287382/7million rials annually in the study area. Dividing this figure by the total area of ecosystems studied, the average per hectare of ecosystem protection against 8888 thousand (according to the area of 32332 hectares’ area) is obtained. It is recommended at least annually, equivalent to 8888 million (annual preservation value per hectare) Rials for investment protection Khaeiz area. It represents the estimated total value of ecosystem protection in the region. In other words, the ecosystem of the region also has many other values for example, biological control of pests, pollination, water and soil conservation, medicinal plants and byproducts, capture and storage of carbon dioxide and produce oxygen, biological diversity, prevent soil erosion, combat air pollution, noise reduction, mitigation and climate stylized, green spaces and landscape and natural scenery, temperature adjustment, increase groundwater resources and consequently the springs and rivers, others noted that their value should be estimated. Discussion and Conclusion: In this study, the current situation is an important step to safeguard protected areas and natural resources and move towards sustainable development. Also for planners, managers and decision-makers provide justification to the quantity and quality of natural resources to support them.

The main objective of this research is to determine recreation value of Nour forest and measure willingness to pay (WTP) in Mazandaran Province. Logit model, CONTINGENT VALUATION METHOD (CVM) and maximum likelihood METHODs were used for calculating this VALUATION. Used data were collected by filling 600 questionnaires from this place visitor. The results showed that 81.2% of respondents were ready to pay for recreation in Nour forest and the mean of WTP for recreation value of Nour forest calculated 2950 Rial/ person and 14160 Rial/Family and recreation value for each hectare of Nour forest is 809327 Rial. In addition, the results showed that price offer and visitors' income variables which are significant have the most impact on willingness to pay of Nour forest visitors and years of education, family size and being regional variables were the next effective factors on willingness to pay quantity.

One of the goals of watershed management operations is preservation and restoration of welfare values of residents. Wetlands as a part of watershed are always important in viewpoint of ecosystem, environment and promenade. Protecting value of wetland includes the benefits obtained from conservation of non-use functions of the ecosystem. This study determined the protecting value of Gomishan Wetland in Golestan province using conditional VALUATION with double-bounded dichotomous choice questionnaire. For this purpose, the questionnaires were distributed among the visitors in 2010 after regional interview. The results indicate that the average people willingness to pay for wetland conservation was 6.58$ and 35.41$ per year for each person and household (5.4 person), respectively. The protective value of the wetland was estimated about 2520000$. Based on the result of the study, it is recommended that policy makers should improve the quality of ecosystem capabilities by allocating sufficient funding.

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.

The aim of this study is to determine the recreation value of Arghavan Forest Reserve in the county of Ilam using CONTINGENT VALUATION METHOD. To determine the influencing factors on the probability of willingness to pay (WTP) of visitors, Logit model was applied using maximum likelihood estimation. Required information were collected via questionnaires and interviews with 245 visitors from the area in 2014. The results showed that 90% of respondents are willing to pay for recreational use of the forest area. Education, income and age variables have a significant positive effect and the variables of offered price, household size and numbers of visits from the region have a significant negative effect on the probability of willingness to pay. The mean of willingness to pay for recreational use of the area was estimated 10202 Rial/person. The annual recreational value of Arghavan Forest Reserve was also estimated 15054352398.33 Rials for total area and 88555014.10 Rials per hectare. The results of the study show that the people are aware of the importance of forest resources and there is a significant willingness to pay to improve and to develop the resources for recreational and protection uses. The results can provide conditions for policy-makers and responsible people in natural resources of Ilam province to conserve and protect more these forest resources.

Today, with the increasing attention of economic policy makers to economic development and growth, and less attention to the effects of this growth and development, we are witnessing the destruction of environmental goods. One reason for the lack of attention to environmental issues is the lack of awareness of their actual value. So, environmental studies can be helpful. In this study, we want to determine the factors affecting the willingness to pay for visitors of Nazhvan Park which is located near the Zayandehrood River. Results from 313 questionnaires were completed from visitors and estimating Logit model shows that the offer price variable at 1%, sex and numbers of visits variables were significant at the 10% level. Finally, the average willingness to pay for recreational use of the Nazhvan Park visitors, was calculated to 1530 Rials. Given that women are more willing to pay, so building the parks for ladies in the city has economic justification. This means that costs of keeping the park can be met from visitors. Numbers of visits variable is significant and has positive impact on willingness to pay. So, improving transportation system for better access to the Park can increases non market VALUATION of Nazhvan Park and visitors' satisfaction.

This paper aims to measure recreational value and willingness to pay for Chahnimeh recreational site which is located in Zabol in Sistan and Baloochestan province. For this purpose, CONTINGENT VALUATION METHOD was used. Also, logit model was estimated to find out factors affecting willingness to pay of people who visited Chaahnimeh. Data were collected from a sample of 142 visitors through filling up questionnaires and interview in spring of 2011. Results showed that 93% of visitors were willing to pay for visiting Chahnimeh. Also, coefficients of proposed amount, income, gender, and occupation, number of visits and interest to maintain Chahnimeh environment were significant at 5% level. The average willingness to pay for each visit was 3,920 Rials and annual recreational value was 1.568 billion Rials. Number of annual visits had negative effect on the amount of willingness to pay. Finally, some recommendations are made to improve present situation.

Lighvan Chay River in East Azerbaijan province named as one of the important tourism zone of the province because of its many natural places for leisure, entertainment and recreational opportunities like field trips and camping. Environmental goods and services are more open access public goods. Lack of awareness of the actual value of the environment is one of the important factors of ignoring the environmental issues and causes environmental deteoration. Therefore, the issue of estimating the environmental value can be helpful to policy-makers and practitioners involved in the conservation and management of natural resources. The aim of this research is to estimate the conservation value of the Lighvan Chay River with the use of CONTINGENT VALUATION METHOD and Double–Bounded Dichotomous Choice (DDC). Results from 149 questionnaires were completed from visitors (in the summer of 2012). Estimating logit model shows that the price offer variable at 1%, marital status and satisfaction of utilities variables were significant at the 5% level and numbers of visits variables was significant at the 10% level. The offered bid variable has marginal effect -0.00004 shows that an increase a unit of bid makes 0.00003 unit decrease in WTP. In this paper willings to pay to protect the area was calculated $2 per month per person by using Shazam 10. Since the average family size was 4.22, so average willings to pay of each family per month was $1.9340. Finally, Mean willingness to pay for each family per year, was calculated $1. Therefore, the formation of the association to preserve the area is recommended. However, according to the positive effect of numbers of visits variable, to facilitate the area’s accessibility by improving road networks is recommended.
