When University of Georgia researchers bred their latest
turfgrass varieties, they had home lawns, athletic fields and
pastures in mind. Now grasses they bred are also being used to
prevent erosion and rebuild land after wildfires and hurricanes.
“When we bred our new tall fescues, we bred them to be suited for
Georgia and to be drought tolerant,” said Bob Carrow, an
agronomist with the UGA College of Agricultural and Environmental
Sciences. “Now the seed companies’ major business with these
grasses is in land reclamation.”
Perfect for neglected areas
Carrow said seed companies are marketing tall fescue for planting
in harsh environments.
“It’s being used to rebuild areas after fires and for highway
stabilization to prevent erosion,” Carrow said. “Landmark Seed
Company is using our tall fescue releases to rebuild the western
U.S. after fires and they’re using it in China where there are
severe erosion problems.”
UGA turf breeders discovered the alternative uses for the
turfgrass during research trials.
“We found, and the seed companies obviously agree, that these
tall fescues are perfect for areas that you don’t maintain
often,” he said. “The Southeast tall fescue variety in particular
is perfect for planting along roadsides.”
Accounting for half of seed sales
Some turfgrass seed companies are now selling as much as half of
their seed for land stabilization and reclamation uses, he said.
Another UGA turfgrass is being promoted for reclamation, too.
Seaspray, a seashore paspalum grass, was co-developed by UGA and
Turf Seeds of Oregon. The world’s first seeded seashore paspalum,
Seaspray is available now in limited quantities.
“Seaspray’s parent grasses originated along coastlines,” said
Paul Raymer, a UGA agronomist and one of the grass’ breeders.
“The new seeded variety should be a natural fit for reclamation
projects in coastal areas or were salt is a problem. And its
original selling point was that it is very salt tolerant.”
Raymer says Turf Seed representatives see the potential for this
grass in reclaiming and stabilizing soils in coastal areas.
“Seaspray’s perfect for areas where the ground cover has been
lost from saltwater storm surges like hurricanes or even the
recent catastrophic tsunami,” Carrow said.
