A couple of decades ago a European tree frog was discovered by the scientists for the first time in Lithuania. It is believed that the tree frogs lived in Lithuania in earlier times, were extinct and nowadays are returning.  Now the tree frogs live in a rather small area in the southern Lithuania and slowly spread to the north. To improve their living conditions their habitats are being restored in the framework of the project. Moreover, the tree frogs are reared from the eggs to froglets to protect the most vulnerable life stages from the predators and enhance their survival rate. Currently the froglets are being released back to their habitats. The video material about the rearing can be watched here.
