The European Tree Frog lives throughout most of Europe and down to the northern parts of the Middle East. They prefer to live in broad-leafed and mixed forests, bushlands, meadows, and shrubland. The frogs vary in color from green, gray, brown, and yellowish.
Mating occurs between March and June. First, the males move to ponds, lakes, and other stagnant water bodies and start calling. Once a female arrives, the male grasps her from behind in amplexus. Then, the female lays her eggs and the male fertilizes them. The female lays between 200 – 2000 eggs. Neither parent provides any parental care. The eggs hatch into tadpoles in 10 – 14 days after being laid. Then, the tadpoles usually complete their metamorphosis in 3 months, peaking in July.
The International Union for the Conservation of Nature (IUCN) Red List categorizes he European Tree Frog as Least Concern for Extinction. They have a wide range and are thought to be abundant throughout it. There are local population declines due to habitat loss from destroying forests to make room for urban development.
