The Need for Seeds

The North Carolina Botanical Garden collects seeds to ecologically restore native plant species after natural disasters strike

A brimmed hat keeps the sun out of Amanda Faucette’s eyes as she leans down to grab something in the grass on the side of Mashoes Road, off of U.S. Route 64 near Manns Harbor. Cars speed by as she wanders through the weeds. She hears the sound of rubber halting on pavement and turns to see an elderly man getting out of his car. He wants to know what she’s doing on the side of the road, and he’s surprised to hear she’s collecting seeds from inside the spikey green fruit of a sweetgum tree — a common, weedy plant.

“Usually, when we’re on the side of the road bent over in the weeds, people look at us like we’ve lost our minds,” Faucette says with a laugh. The conservation botanist at the North Carolina Botanical Garden, Faucette is integral to the garden’s role in Seeds of Success (SOS) — a national native seed collection program led by the Bureau of Land Management (BLM) within the U.S. Department of the Interior.

Since 2001, the SOS program has collected seeds to restore native plant species after major natural disasters like wildfires, hurricanes, and flooding. Until last year, most of that seed collection took place in the western United States, where BLM administers 264 billion acres of lands — they manage next to none in the East.

“We were not getting much funding or attention,” Johnny Randall, director of conservation programs at the Botanical Garden and adjunct faculty in the UNC-Chapel Hill Curriculum for the Environment and Ecology, says. “But because of damage caused by Hurricane Sandy and the need for seed on federal projects, especially at national wildlife refuges, we got together with two other botanical institutions to write a grant proposal to collect seeds. Seeds of Success East was born.”

The dirty details

Before going into the field, Faucette reached out to leaders from Hurricane Sandy restoration projects to learn the plant species that needed collecting. “Most of the species on our list are matrix species — the workhorses of an ecosystem that are often the first plants to develop and colonize an area after there has been a disturbance,” she says. “You get more bang for your buck as far as the plant is concerned. They do more work in regard to soil retention and reclaiming an area than other plants would.”

Faucette and her four interns for the project often found themselves knee-deep in wetlands, salt marshes, and estuaries. “We’d be out there in waders with pole pruners collecting seeds from plants that most people consider weeds,” she says.

Seed type and quantity determined the locations they visited. “We had to find areas where there were enough of these plants to collect a minimum of 20,000 seeds per species accession, but not negatively impact the native seed population in that area,” Faucette says.

It’s a bit more involved than it sounds. “First thing you need to do is grab a seed head,” Faucette instructs, “and then you need to find out if there’s any seed in it. And if there is seed, is it viable? Is it alive? Some plants will produce what looks like a seed, but there’s actually nothing inside of it.”

After collection, seeds get stored in paper bags. Then, they need to dry out — moisture will breed fungus and destroy the crop. “It’s very low-tech,” Faucette chuckles. She recalls the interns traveling long distances for seed collection, which meant hotel rooms became their labs. “They’d have luggage carts overflowing with plants and bags of seed. And they’d have seeds spread out all over their hotel rooms to try to get them to dry before they went out the next day.”

Space and resources weren’t the only hurdles the interns came across. On a few occasions, they stumbled upon black bears. And one intern got her rental car stuck in a ditch at Alligator River National Wildlife Refuge. A handful of locations required the interns to hop into a boat. “They’d be in canoes beating off the cones from bald cypress and fruits from water tupelo trees,” Faucette says.

A germinating program

Faucette and her team collected approximately 4 million seeds this past year — and they still have one more year to go. So far, the project has gone very well and completely according to plan. It actually exceeded expectations. SOS East is actively seeking funding for continuation of the project — and perhaps an expansion.

“Right now, SOS East is concentrated on the Mid-Atlantic Region because of hurricanes and flooding,” Randall says, “but I’d like to see it expand to the South-Atlantic coast as it’s more vulnerable to hurricane damage than the Mid-Atlantic. Plus, hundreds of thousands of acres there have been burned from wildfire.” Forty percent of the nation’s forests reside in the South, which leads the nation in annual wildfires, according to research from the USDA Forest Service Southern Research Station. In 2007 alone, several wildfires along the Georgia-Florida border near the Okefenokee National Wildlife Refuge burned approximately 600,000 acres.

Local seeds are ideal for restoration thanks to ecotypes — genetically distinct plant variations that have adapted to specific environmental conditions. “The ecotypic seed phenomenon is real,” Randall says, “so if you want to have a successful project, you want seeds from plants that are locally adapted for those sites.” And the North Carolina Botanical Garden could be a hub, able to help local agencies with restoration and rehabilitation after natural disasters strike.

The project needs to go beyond seed collection, Randall stresses, to truly be successful. Four million seeds sounds like a lot, but that only goes so far in restoration. Growers will need to plant those seeds to produce thousands more in seed increase plots — an economic driver, Randall says, for people to open seed conservation businesses. Ernst Conservation Seeds, located in Pennsylvania, is one of the only companies in the eastern United States that grows, processes, and sells seeds.

“There will be a need for seeds,” Randall says. “We don’t know where, and we don’t know when — but these storms happen every year. And you don’t want to look for the seed after the storm occurs.”
