Swamp
project moving forward Despite receiving
only a trickle of funding, the Forest Service is moving forward with rehabilitation
of Trout Creek Swamp west of Sisters. The swamp is an old grazing site that
was established back in the 1930s when ditches were dug to drain the swamp
for pastureland.
The alterations also removed
the stream flow from its historic path.
Last year, the Forest Service
launched a restoration effort to return the site to its natural state,
said fisheries biologist Mike Riehle.
"It's a sizable meadow project,
and we haven't done many of those in this district."
Trout Creek abounds with native
redband trout, and the goal of the project is to mimic a natural system
that retains water like natural beaver dams.
Riehle said that meadows that
hold water in ponds and marshes make for better fish habitat.
The redband trout is classified
as a "sensitive species." While the trout are not endangered, their survival
is enough of a concern that officials closely monitor the native variety
of rainbow.
Riehle said that, in spite
of its name, the area is not a true swamp. "It's really a brown moss fen,"
he explained, "and it's not a bog because it actually has water that moves
through it. There's a unique plant community associated with it and that's
what we're trying to protect."
Riehle said that the plan
is to fill in the artificial drainage ditches to restore the natural wetlands.
The natural meandering stream
channel -- though dry -- is still visible in the area, and the Forest
Service wants to put the water back where it belongs. When water saturates
a meadow, moisture is retained in the system and the stream keeps flowing
longer during dry spells and rebounds more quickly when water flow increases
again.
Thus far, no channel work
has been undertaken because the project has been hampered by a lack of
funding.
One problem that has been
attacked, however, is the encroachment of lodgepole pine into the drying
meadow.
Riehle estimated that approximately
50 burn piles were created from removal of young trees in the targeted
wetland area.
"We're going to burn some
of the piles this fall," Riehle said, "but most will probably wait until
next year."
Another concern is the spread
of reed canary grass, an exotic plant sprouting in the area that displaces
native wetland plants.
The native plant community
includes a number of interesting carnivorous plants and multiple species
of sundew and bladderwort.
Rather than burning the reed
canary grass, Forest Service botanists decided to try cutting it with
weed-whackers in the hope that native grasses would re-colonize the affected
areas.
So far, the plan seems to
be working, although it will take more time before it is known whether
the low-impact method will succeed.
Riehle said that the Forest
Service is coordinating with the Upper Deschutes Watershed Council to
create the best plan for the area and also to seek funding for the project.
He hopes that excavation to
restore the original stream channels can begin next year.
Farther downstream, Trout
Creek normally peters out and flows underground before it reaches Sisters.
Technically, though, it's a tributary of Indian Ford Creek.
The natural channel for Trout
Creek passes north of the Forest Service compound in Sisters and behind
the Sisters Industrial Park.
Periodically, a wet year causes
the creek to flow right through town. The last time it did so was six
years ago when it flooded Camp Polk Road just beyond the airport.
Part of lower Trout Creek's
seasonal channel runs between Tollgate and Sisters High School, which
uses the land for educational and scientific purposes.
The 160-acre parcel is managed
in cooperation with the Deschutes Basin Land Trust and includes important
habitat for the Peck's penstemon, a rare plant that is found only in the
Sisters area. |
