The Hula Valley is an agricultural region in northern Israel with abundant fresh water, which used to be Lake Hula, prior to its draining. It is a major stopover for birds migrating along the Syrian-African Rift Valley between Africa, Europe, and Asia.
Lake Hula and the marshland surrounding it were a breeding ground for mosquitoes carrying malaria, and so were drained in the 1950s. A small section of the valley was later re-flooded in an attempt to revive a nearly extinct ecosystem. An estimated 500 million migrating birds now pass through the Hula Valley every year.
