BISMARCK, N.D. (AP) -- Federal wildlife officials are taking applications from farmers who want the government to remove cattail-infested wetlands, the preferred habitat of sunflower-snacking blackbirds.

Phil Mastrangelo, the state director for the U.S. Department of Agriculture's Wildlife Services agency, said applications will be accepted from Wednesday until June.

More than 60,000 acres of cattail marshes in North Dakota have been destroyed since 1991, to try to keep blackbirds from attacking sunflower fields, he said.

Cattail eradication leaves blackbirds without a place to nest or roost and makes them more vulnerable to predators, said Larry Kleingartner, executive director of the Bismarck-based National Sunflower Association.

"It has been the most effective tool we have in dealing with blackbirds," he said.

Last year in North Dakota, about 3,700 acres of wetlands in seven counties were treated, Mastrangelo said.

A herbicide is applied in late summer from a helicopter, at a cost to the government of about $22 an acre, Mastrangelo said. The agency had hoped to treat double the amount of wetlands last year but the cost of the herbicide doubled, he said.

"The increased cost in herbicide reduced the amount of acres we could treat," Mastrangelo said.

The amount of acres that will be treated this year is still unknown, he said.

"We won't know for at least a couple of months if the herbicide stabilizes in price, goes up or hopefully goes down," he said.

The program targets only cattails on private land and is free to sunflower farmers.

Kleingartner said blackbirds eat more than $20 million worth of sunflowers each year in North Dakota, which accounts for about half the nation's sunflower production.

Some 70 million blackbirds come through the Northern Plains each year, including about 6 million that stop in North Dakota, biologists say. Each blackbird can eat about an ounce of sunflower seeds daily.

Cattails cover some 600,000 acres of wetlands in North Dakota. Mastrangelo said wetlands treated with the herbicide are typically free of cattails for about five years.

Noise cannons also are used to shoo blackbirds off sunflower fields.

Sometimes nothing works, so farmers have either quit growing the crop or planted in other areas, Kleingartner said.

"Some farmers have just found out that they can't competitively produce the crop without blackbird damage," he said.

Increased corn production in North Dakota has helped sunflower farmers some, Kleingartner said.

"Additional acres of corn have provided an additional feeding source," Kleingartner said. "But definitely, blackbirds still prefer sunflowers to chew on."

PORTLAND, Ore. (AP) - Damage estimates to Oregon's nursery stock industry from late December storms suffered by 160 growers in 12 counties range from $18 to $31 million in a survey conducted by the Oregon Association of Nurseries.

"It's now clear that damage to nursery and greenhouse structures and crops was widespread and extensive," said association President Tom McNabb.

Hardest hit were greenhouses and other structures used in the production of nursery and greenhouse crops. Growers reported the total estimated cost to repair or replace damaged greenhouses and structures at $10.8 million.

The nursery industry is Oregon's most valuable agricultural producer, with sales topping $1 billion last year. About 81 percent of the output goes out of state, nearly 50 percent east of the Mississippi River.
