This handout photo taken on December 2, 2016, provided by the El Pinacate and Great Altar Desert Biosphere Reserve, shows a European hare (Lepus europaeus) in the reserve along the US border in northern Mexico. Threatened species like the Sonoran pronghorn or desert bighorn sheep freely cross the border between Mexico and the United States in protected biospheres, but the construction of US President Donald Trump's wall will block their movement in these desert valleys and could drive them to extinction.
