From vernal pools formed by spring meltwater to vast stretches of black spruce forest, the Innoko National Wildlife Refuge provides habitat for an abundance of wildlife, ranging from tiny song birds to the Alaskan moose (the largest member of the deer family). World-record sized Northern Pike lurk beneath the coffee-colored water of the Innoko River, where there are over twenty species of native fish. The network of wetland lakes attracts vast flocks of molting Greater White-fronted Geese, making the Refuge one of the most important waterfowl areas in Alaska.

There are 124 bird species that have been recorded on the Innoko Refuge. The following link will bring up our bird list (pdf).

    Among mammals, rodents account for more species than any other group on the Refuge, yet they are some of its smallest residents. As the name suggests, the Alaska Tiny Shrew (Sorex yukonicus) weighs little more than a paperclip! Two of the more famous rodent residents are beaver and porcupine; one known as nature’s engineer and the other for their sharp quills. But did you know that there is a rodent able to glide from tree to tree? The Northern Flying Squirrel is a seldom seen northern forest dweller.

    Wood frog

     The “quork, quork, quork” of male wood frogs (Rana sylvatica) calling for mates is a springtime ritual in ponds throughout the Innoko National Wildlife Refuge. They are the only species of amphibian able to survive in the arctic. How is that possible? Seemingly a creature from science fiction, wood frogs are able to freeze solid while they hibernate through the subzero temperatures of winter, and await the spring thaw.
