FLOODED FARM FIELDS BENEFIT NATIVE FISH

CORVALLIS - Farmers' fields that are seasonally flooded play a role, not only in creating a sanctuary for fish during high-velocity water, but in providing access to high-energy foods and places for breeding, according to researchers at Oregon State University Oregon State University, at Corvallis; land-grant and state supported; coeducational; chartered 1858 as Corvallis College, opened 1865. In 1868 it was designated Oregon's land-grant agricultural college and was taken over completely by the state in 1885. .

Even more important, the researchers say, is that these "intermittent watercourses" are dominated by native fishes whose behavior may have evolved to take advantage of such conditions.

"Floods have always been a dynamic part of the system, much the same way that snow is for elk in Yellowstone," said Guillermo Giannico, a freshwater fish ecologist at Oregon State University and one of the authors of the study. "Over time, animals will adapt to get the most out of their habitat. We have found that native fish have adjusted their behavior to use these floodplains, mostly in agricultural lands, to great benefit."

In their study, the researchers call for the promotion of agricultural conservation practices in floodplain floodplain, level land along the course of a river formed by the deposition of sediment during periodic floods. Floodplains contain such features as levees, backswamps, delta plains, and oxbow lakes.  habitats. Although many of the complex channels of streams and rivers in the Willamette Valley have been lost to development, those remaining in these agricultural lands are of benefit to native fishes, Giannico said.

The research team studied five sub-basins in the Willamette River drainage - the Luckiamute River, Mary's River and Long Tom River on the west side of the valley, and the Calapooia River and Muddy Creek on the east side. These sub-basins include the high-elevation Cascade Mountains, the hills of the Coast Range and the floor of the Willamette Valley, where most of the flooding would occur.

Researchers discovered 13 different fish species, and only three of those species were exotic, or non-native. Even more surprising to researchers was the number of native versus exotic individuals. Of the 1,526 fish they captured, almost 99 percent were natives. The most common were redside shiners (534 individuals) and threespine sticklebacks (347), which were found at nearly three-fourths of the sites. They also found tiny Chinook salmon chinook salmon

 and cutthroat trout, as well as speckled dace, large-scale suckers and northern pikeminnows, which are native to the valley.

BEAUTIFY Your BACKYARD

Learn how to create native backyard habitats during a Nearby Nature workshop from 3 p.m. to 6 p.m. Saturday at Alton Baker Park Alton Baker Park is located in Eugene, Oregon, United States, near Autzen Stadium. It features duck ponds, bicycle trails, and a dog park, and directly touches the Ferry Street Bridge. .

 before the dry Willamette Valley summer. The workshop will offer tips on how to create water-wise native plants that support native wildlife. The instructors will be Bruce Newhouse, from the City of Springfield Planning and Development Department, and Yotokko Kilpatrick, the founder of Walama Restoration. They will teach about Willamette Valley habitats, plants and pollinators. Those attending will be allowed to take starts and seeds home to plant in their own yard. Details: www.nearbynature.org.

FISHING

Rivers and streams: Last week, Alton Baker Canoe Canal was stocked with 1,500 rainbow trout. Note that non-adipose fin-clipped trout are legal to harvest in the canal.

Large brood trout, ranging in size from eight to 18 pounds, were released at Junction City Pond. The fish are 4- and 5-year-old rainbow trout from ODFW's Roaring River hatchery hatchery

a commercial establishment dedicated to the hatching of bird eggs to provide day old chicks and poults to the poultry industry.

ODFW ODFW Oregon Department of Fish and Wildlife  reports that the sturgeon bite on the lower Willamette River is improving.

Marine zone: Bank fishing at the mouth of the Elk River has been very good on days during and following the big tides. "Numerous" 50-pound fish have been caught that way, said John Gross of Roaring Fork Guide Service. Low water has made driftboat passage upriver difficult on both the Elk and Sixes. Flies have been the best producer, Gross said, with bait No. 2, and then spoons, spinners and plugs trailing.

ODFW reports suggest chinook Chinook, indigenous people of North America

 catches on the Siuslaw River have been slow to fair. The Alsea River looks like a better bet right now; fall chinook there can be found from the lower bay up to the fishing deadline at Five Rivers. Many fish have moved upriver above the fishing boundary, but fresh, bright chinook should continue to pulse in over the next few weeks.

HUNTING

Timely tips: At this time the deer are rutting, and hunters can expect to find bucks hanging around close to does. Thick cover on the coast and Cascades will make spotting deer more difficult, but hunters can take advantage of scents and rattling antlers to draw a buck into the open.

VIEWING

Best bets: Bald Eagles are now commonly seen along the mainstem portion of the Umpqua River from Roseburg to Reedsport.
