Along the tour route, you may have noticed rows of old juniper fence posts. Volunteer groups have contributed hundreds of hours removing the old wire fences that were hazardous to wildlife. Many posts were left in the ground as perches for raptors, which you may see hunting over the meadows. In the wetlands, these posts are often used by gulls and terns, and you may be lucky enough to spot a Willet or Wilson’s Snipe on one.
You will also notice that the river has been straightened and channelized along this stretch. This was done by private landowners beginning in 1910. As part of the Swamp Act, landowners drained the meadows to create areas for grazing and haying. This channelization is currently used by the Refuge in managing wetlands, but it provides challenges for the native redband trout (a subspecies of rainbow trout), which has inhabited the Blitzen River since the last Ice Age. The Refuge is developing a long-term plan to make the river more habitable for these specially adapted fish. Watch for some of the sophisticated fish passage structures at various points along the river.
To continue the auto tour, proceed down the Center Patrol Road and turn at the signed right turn to Buena Vista Ponds.
