Rediscovery
The IUCN has classified this species as extinct since 1996 but Israel continued to list it as an endangered species in the slim hope that a relict population may be found in the Golan Heights.
In 2000, a scientist from the Lebanese nature protection organisation A Rocha claimed he had seen a frog species which could be Discoglossus nigriventer in the Aammiq marshes south of the Beqaa Valley in Lebanon. Two French-Lebanese-British expeditions in the years 2004 and 2005 yielded no confirmation as to the further existence of this species. In August 2010, a search organised by the Amphibian Specialist Group of the International Union for Conservation of Nature set out to look for various species of frogs thought to be extinct in the wild, including the Hula painted frog.
In 2011, a routine patrol at the Hula nature reserve found an unknown frog and scientists confirmed that it was one of this rare species. An ecologist with the Israel Nature and Parks Authority credited the rehydration of the area for the frog sighting. On November 29, a second specimen was located in the same area. The second Hula painted frog, a female, was found in swampy weeds twenty centimeters deep. It weighed 13 grams, half the weight of its male counterpart. Since the discovery of the first specimen, at least ten more individuals have been found, all in the same area.
