The European tree frog (Hyla arborea) is a small tree frog. As traditionally defined, it was found throughout much of Europe, Asia and northern Africa, but based on molecular genetic and other data several populations formerly included in it are now recognized as separate species (for example, H. intermedia of Italy and nearby, H. molleri of the Iberian Peninsula, H. meridionalis of parts of southwestern Europe and northern Africa, and H. orientalis of parts of Eastern Europe, Turkey and the Black Sea and Caspian Sea regions), limiting the true European tree frog to Europe from France to Poland and Greece.

Global Distribution

Where this species is recorded worldwide. Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
