The long-term sustainability of ecosystems and the services they generate depend on the conservation of biodiversity on a landscape scale.

on Thermal resources can
be used; to improve in health, to heal and to freshen.
In this study we estimated the use value of ecosystem services in the Yalova Thermal Spring. Thermal sources are one of the non-monetary natural resources and have positive effects on human health.

Travel Cost Method (TCM), is aiming to estimate the recreational use value of area with determining current demand. The assumption is accepted the travel cost equal to;
transportation cost and
time opportunity cost which spent for a recreation tour

Demand function is estimated between travel costs and number of visits.
v=f(c,x) In the formula;v: number of visits,c: travel costs,x: all other variables
So, the accepted assumption is consists of a travel-production function that defined the relationship between the demand for area and incurred expenses.

In the calculation of consumer rant firstly individual’s consumer rant calculated. Consumer rant for the semi-logarithmic function type is as follows: Consumer rant
CRYL=q/-βYL
CR: individual consumer rantq: individuals average visit numberβ: the slope of demand function (expense coefficient)
