Araucaria angustifolia is one of the main species of Brazilian flora due to its cultural, environmental and economic value. Thanks to its intense exploitation for many years, this species was included in the Official List of Endangered Brazilian Species, recognized in its latest version by the Ordinance MMA n. 443/2014, with the species classification “In Danger”. Currently, studies on the ecosystem valuation of A. angustifoliaare necessary, aiming at the conservation of the species, with this in mind, we must consider that trees provide society with a set of environmental benefits, which can be monetarily quantified. Thus, this study aimed to economically value the existence of A. angustifolia in the municipality of Dois Vizinhos, Paraná, using tools from the Environmental Services Policy, with the contingent valuation method, linked to the photointerpretation of the World satellite image View 3. Finding through interpretation of the satellite image 4,857 araucaria individuals and an average Willingness to Pay (WTP) value of R$ 12.65 per year with the estimated value of each tree for the purpose of paying for environmental services being R$ 73.21 per tree/year for each conserved tree per capita values were also achieved with the help of IBGE census data in the municipality, finding the value of 5.7 trees per capita in the urban area and 1.7 trees per capita in the rural area, totaling 7.4 trees per capita in the municipality of Dois Vizinhos, Paraná.
