A researcher from the Volcani Center, Israel's agricultural research organisation, places an automatic movement camera on a tree, to monitor mountain gazelles in a forest near Moshav Mesilat Tzion, west of Jerusalem, on January 4, 2021. - Israel is one of the last places where the endangered mountain gazelle roams in the wild but, as development shrinks their natural savannah habitat, ecologists are studying if they can also thrive in forests. Wildlife experts hope their population can recover in woodlands like the Forest of the Martyrs west of Jerusalem, where six million trees were planted after World War II, reflecting the number of Jews killed in the Holocaust.
