The document outlines a botanical route project through Castelló d'Empúries that was designed to classify and identify local tree species. The project involved researching tree species, determining the study zone, photographing trees, creating identification keys, and designing the route which was divided into two subzones. While 11 tree species were identified, including Platanus x hispanica, Populus alba and Populus nigra, the route could not be completed with students as planned.
