More than 300 deer live in the 68.66 sq km wetland. This species of deer was first made known to western science in 1865, by Father Armand David (Père David), a French missionary working in China. Hunting made the species extinct in the wild and it is now known only in captivity Photograph: China Photos/Getty Images Coloured leaves cover stones in the Schlaube river near Bremsdorf, eastern Germany.

Generations of cattle owners who dipped their livestock in pesticides ended up killing not only the ticks that feast on them, but also the red-billed oxpeckers that eat the ticks.
