Summers here are long enough for broadleaf trees to replace conifers. Broad leaves are much easier to eat and digest so now animals can collect their share of the energy that has come from the sun. It' s summer and these forests are bustling with life. But the good times will not last. Broad leaves must be shed in winter for their damage by frost. As they disappear, so the land becomes barren with little for animals to eat. The inhabitants must migrate, hibernate, or face months of near starvation. The Amur leopard the rarest cat in the world. Here, in the deciduous forests of eastern Russia the winter makes hunting very difficult. Prey animals are scarce, and there' s no concealing vegetation. The cub is a year old and still dependent on its mother. Deer are frequent casualties of the harsh winter and these leopards are not above scavenging from a corpse. African leopards could never survive here, but the Russian cats have thick fur to shield them from the cold. |
