In some small nature reserves in Belgian Limburg and Dutch Limburg you can find tree frogs (Hyla arborea). These tiny frogs are only 2 to 4 cm in length. They are green and have a brown lateral stripe from the eyes to the groin. Females have white throats, while males have golden brown throats. They mostly can be found on brambles near small streams or ponds.
