Hula painted frog

Previously found only in the Lake Hula marshes of Israel before the lakes were drained to make way for farmland, these colorful frogs were believed extinct until one specimen was found during a routine patrol in the Hula nature reserve. The discovery boosted search efforts, which later turned up 10 more specimens.

More water was diverted to revive the marshes of the reserve, which is credited with the species' re-emergence. While the discoveries have been exciting, they are also only preliminary. It's still a very small population, and the frog has a long way to go before it can be considered a conservation success story.
