200 - L'Arboretum

Itinerari situat dins de la ciutat de Lleida, a la comarca del Segrià. Té una longitud total de 1.338 m dividits en 6 seccions, i es troba a una altitud mitjana de 185 m. Els comptatges es van realitzar els anys 2021 i 2022.

L'Arborètum és un jardí botànic on el referent són els arbres, i les seccions discorren per diferents espais que representen quatre biomes arboris: boscos boreals, boscos caducifolis, boscos esclerofil·les i selves temperades. Entre els arbres hi ha espais oberts amb vegetació herbàcia variada i diverses làmines d’aigua. Sempre hi ha plantes florides, representant un veritable oasi per a les papallones durant els estius calorosos i àrids propis de la plana de Lleida.
