Around the world, there are several ecosystems, some in their initial conditions, which are unique and need preservation. This heritage needs adjusted management plans and con- servation attentions. It is important to preserve the natural heritage for the future genera- tions, creating active legislation, more governance, empowerment for the related institu- tions, and bringing more dynamics for these frameworks. However, the literature shows that these issues may be explored deeper. In this context, using data from the Portuguese Institute for Conservation and Nature, this work discusses the heterogeneous distribution of Trees of Public Interest (TPI) in Portugal. These trees are relevant for several criteria such as size, age, or cultural value. Through the use of Poisson, negative binomial, zero- inflated Poisson, and zero-inflated negative binomial regressions, several conclusions have been reached. Among these conclusions, it is highlighted that areas characterized by higher levels of touristic dynamism tend to increase the number of TPI. Higher percentages of for- estry area for intervention ensure at least one TPI. The age of the creation of the municipal- ity also significantly influences the risk of having no TPI.
