Yes mam I am looking for monetary terms. Moreover thinking about Barter system to compare the monetary amount but it seems not scientific enough. So please help in this regards through valuable suggestion or some literature etc.
I suggest to search for studies carrying monetary valuations of ecosystem services provided by forest ecosystems, such as choice experiments and/or hedonic pricing and/or travel cost methods. You should also find some literature on Payments for Environmental Services (PES) that might give you an insight
Some hints:

You can try our method - evaluation based on ecosystem characteristics. It needs characteristics of forest site and forest stand. Method includes financial expression of forest ecosystem value. We using it not only for natural forest, but for managed forest or damage on forest too. Below is method and examples.

You can get an idea of the analytical framework you may need from: Targeting investments to cost effectively restore and protect wetland ecosystems: Some economic insights.
I think that the first question to determine the best method is: which ecosystem services are you going to evaluate? Depending on it you have plenty of methods to estimate virtual economic values from forests based on surveys or participatory surveys.
Anyway, Forest engineers usually take account of the actual economic value of forests by using different economic methods. Maybe you do not need to adopt the Ecosystem Services Approach to calculate economic benefits from forests.
