KLAMATH FALLS, Ore. – Cattails and bulrushes
could be working their way into crop rotation in fields around the
lower reaches of the Klamath Reclamation Project.
There’s not a new market for the aquatic plants, but turning fields
into temporary wetlands for one to four years produces fertile soil,
rid of pests, farmers and federal officials say. The practice has been
tested for more than a decade on agricultural land leased on the Tule
Lake and Lower Klamath National Wildlife Refuges.
Now it could be moving to private land.
“It’s really provided an economic value to a wetland, and if you
can give an economic value to something, that is powerful,” said Ron
Cole, refuge manager. “It’s not just a wildlife value or an
ascetic value.”
Farmers want to lease the refuge’s agricultural land that has gone
through the program, bidding twice as much for it as for land that was
in crops the prior year. Some, like Mike Noonan, who farms on and near
Lower Klamath refuge on the California-Oregon border, are trying it
out on their own land or private land they lease.
“It’s a great tool, but the jury is still out,” he said.
Started in the 1990s, the “walking wetlands” program revitalized
refuge fields while providing habitat that quickly draws migrating
birds and spurs the growth of aquatic plants.
“We are seeing birds nesting ... that we haven’t seen nest in
years,” Cole said.
Drowning out pests and nematodes with temporary wetlands saves farmers
a couple of hundred dollars per acre on fumigation costs and boosts
crop production by 25 percent, refuge officials said. The refuge’s
walking wetlands are usually created in February on 200-acre blocks,
using irrigation canal water.

Making the wetlands sometimes requires
building dikes around fields, but it doesn’t require the planting of
aquatic plants. Cattails usually are the first to spring up, growing
from hard seeds that may have been mixed with the soil for 60 years,
said Fran Maiss, deputy refuge manager.
“The seed is there. We don’t have to do anything,” he said.
In fields that stay wetlands for more than a year, bulrushes and other
plants start to grow, also from seed stock already in the ground,
Maiss said.
To ready the field for crops again, it is drained and the aquatic
plants are burned, putting seeds back into the ground.
With the boost in crop yields minus the cost of chemically treating a
field for pests, the fields are hot when it comes bidding time for
lease lands.
“Productive wetlands make for productive croplands,” Maiss said.
Not only do farmers bid twice as much for the land, he said, but also
crops grown in fields that have been under water for three years can
be labeled organic.
Now farmers are trying to figure out if they want to have walking
wetlands on their private land.
Noonan turned 800 acres of private land he leases into temporary
wetlands, but said he wants to see if the federal government will add
incentives by providing funds through the Natural Resource
Conservation Service before deciding how much to involve wetlands a
part of his farming business.
“We just need some additional help to get this done,” Noonan said.
“It’s a dollars-and-cents game.”
If the incentives are right, said Marshall Staunton, a farmer in
Tulelake, Calif., wetlands could work their way into the rotation for
many Klamath Basin farmers. The rotation could be wetland, organic
crops, conventional crops, then back to wetlands.
“It gives you time to rejuvenate some tired ground,” he said.
