The geographic range of redband trout in the interior West has not contracted noticeably. The density of stream habitats occupied has, however, been reduced. In Oregon, roughly 55% of the stream distance historically occupied in occupied today.
There are multiple examples of redband trout following an adfluvial life history behavior to prey on tui chub in lakes. This life history follows closely the life history of anadromous salmon and steelhead and it favors more rapid growth than a fluvial (entirely stream dwelling) life history.
But they are creatures of basins in the Interior West, occupying streams, rivers and lakes from western Montana to eastern Oregon and northeastern California.
The goal of the program is to develop a self-sustaining breeding flock of Trumpeters in Oregon and to develop connections between the Summer Lake and Malheur Refuge swans.
