The monetary valuation of urban forests is a field of study worldwide by which the topic of their fair value is tried to be solved. Montevideo is not foreign to this challenge, being necessary to compare different existing formulas and valuation methods with that used by the local Town Hall. Ten formulas were chosen for the evaluation using methods such as the Helliwell, the Standard Tree Evaluation Method (STEM), the Italian, the French, the Council Tree Landscape Appraisal (CTLA), the Norma Granada, the Intendencia Montevideo (IM), the Valoración Monetaria del Árbol Urbano (VaMA), the Swiss and the Burnley for the appraisal of 31 trees from 18 species by two evaluators. From the 620 evaluations performed, the sources of variation were analyzed: formulas and evaluators. There were no significant differences by those obtained by the latter, but it did among the formulas. They were organized into four groups: group A including the lowest values obtained through the N. Granada, CTLA, Swiss M., Italian M. and Helliwell methods; group B comprising the values that were slightly lower than the mean ones estimated using the Town Hall formula; group C grouping the slightly higher than the mean values calculated using the VaMA, French M. and Burnley methods and group D with the high average values computed using the STEM formula. It can be concluded that the best formula to determine the monetary value of urban trees in Montevideo would not be the one used by the local Town Hall but that of the VaMA method provided that certain adjustments that should be evaluated are made.
