Rivers

There are approximately 80 rivers which flow across the Shiretoko peninsula. They are uniquely short in length and without much meandering each upstream environment is directly connected to the ocean. This environment suits various kinds of creatures, including rare river fish such as the Dolly Varden trout. Many of these rivers are also used by the salmon fish species to lay their eggs. They swim up the rivers in great numbers and in turn create good feeding opportunities for the bears and birds of prey. Their carcasses then go on to fertilise the soil, making their existence vital to the whole ecosystem.
