More precisely, the men who gathered outside the grain elevator in Ksk, Nebraska, believed the 17-year-old girl had lost any sense of what farmland was supposed to be used for.
People said Opal Vance had lost her mind.
More precisely, the men who gathered outside the grain elevator in Ksk, Nebraska, believed the 17-year-old girl had lost any sense of what farmland was supposed to be used for.
In the spring of 1981, Opal took 60 acres of the Vance family’s worst ground, a barren stretch known simply as the flat, and planted 4,000 bur oak seedlings across it.
She did not put them along a fence.
She did not use them as a conventional windbreak.
Instead, she planted them directly across the middle of the damaged ground in long, curving rows that followed the contour of the land rather than the property lines.
The men at the elevator called it the stupidest thing they had seen since old Vernon Prut tried to raise ostriches.
They would continue laughing for years.
The Vance farm sat on the western edge of Kuster County, on a stretch of high-plains ground that had first been broken by plow in the 1890s and had never fully recovered.
Opal’s great-grandfather had come west from Ohio with a team of mules and a head full of ideas about wheat.
For 2 generations, the family wrestled a living from soil that had never been especially willing to provide one.
The house was a low white clapboard building with a windmill that groaned whenever the wind came from the northwest, which it usually did.
Opal’s father, Dale Vance, farmed 400 acres of wheat and milo.
He farmed them the way his own father had, largely because that was the only method he had ever been taught.
The 60 acres that concerned Opal lay on a low rise south of the house.
Everyone in the family had called it the flat for as long as anyone could remember.
It was poor ground.
Most of its topsoil had blown or washed away decades before Opal was born.
What remained was only a thin covering over a hardpan layer of caliche, a chalky, cemented subsoil that water struggled to penetrate and roots could barely break.
Wheat planted there emerged thin and yellow.
In dry years, which were common, it did not emerge at all.
By the time Opal was 10, Dale had largely stopped trying to plant the flat seriously.
The ground remained pale and cracked, growing little beyond Russian thistle and the occasional stubborn patch of buffalo grass.
It became a scar across the family property that everyone had learned to walk around.
Opal did not.
From the time she was young, she paid attention to the flat in a way other people did not.
She was a reader, not only of schoolbooks, though she managed those well enough, but of almost anything involving land.
She read agricultural bulletins her grandmother kept in a drawer.
She studied old Soil Conservation Service pamphlets left over from the Dust Bowl years.
At a rummage sale in Broken Bow, she found a battered college textbook on forest ecology and bought it for $1.
Her grandmother Ruth had been a girl during the dust storms of the 1930s.
She told Opal about the black blizzards, when the sky turned the color of a bruise and remained that way for days.
Ruth remembered her own mother hanging wet sheets over the windows simply so the family could breathe.
She repeated 1 sentence often while sitting with Opal on the porch in the evenings.
“The land doesn’t forget what we did to it. It just waits for us to notice.”
Opal noticed.
She treated the flat the way another person might treat a wound that refused to close.
She walked it constantly and kept a green spiral notebook, the same kind her grandmother had once used to record rainfall.
Inside it, Opal documented what she saw.
When rain came, water ran off the flat almost as quickly as it fell.
It carved narrow gullies that widened year after year.
By July, the soil crust baked so hard that a heavy storm struck it almost as if it were a tin roof.
The water moved downhill toward the county road rather than soaking into the ground.
Nothing taller than knee-high grass interrupted the wind.
On strong March afternoons, fine dust lifted from the flat and drifted clear across the section.
Opal recorded rainfall totals copied from Ruth’s old records.
She also measured new rainfall herself with a coffee can nailed to a fence post.
By the time she was 16, Opal had collected 4 years of her own measurements and approximately 40 years of her grandmother’s.
The numbers told her something the men at the grain elevator would have found even more ridiculous than the trees.
The flat was not merely bad ground.
It was getting worse.
Every heavy rain stripped away more of the remaining topsoil.
Each summer dried it out faster.
During the winter of 1980, Opal wrote to the extension office in Broken Bow asking about planting trees on marginal cropland.
A soil conservationist named Harlon Voss answered.
He sent far more information than she expected.
There were pamphlets about windbreak design.
Erosion-control plantings.
And the Great Plains Shelterbelt Program, which had put millions of trees into the ground across 5 states during the 1930s under President Franklin Roosevelt.
One pamphlet contained a section on bur oak, Quercus macrocarpa.
The species was native to the edge of the tallgrass prairie.
Its roots ran deep.
It tolerated drought.
Its taproot could penetrate hardpan that stopped many other species.
Opal read the section so often that the page eventually came loose from the staple.
In January, she brought her idea to Dale.
Her father listened while she explained the erosion figures, infiltration rates, and root depth.
He stood in the kitchen with a cup of coffee growing cold in his hand.
When Opal finished, Dale answered as most farmers in the county probably would have.
“That ground’s not worth the seed you’d waste on it, Opal. Leave it.”
She did not argue.
Her grandmother had taught her that arguing with a man after he had already made up his mind rarely moved him far.
Instead, Opal asked whether she could have the flat to use as she wished, since Dale was no longer cropping it anyway.
It cost him nothing.
And despite not understanding what his daughter intended to do, Dale loved her.
“Fine,” he said. “It’s yours. Do what you want with it.”
Opal ordered bare-root seedlings from a state forestry nursery that fall.
4,000 bur oak whips.
None much taller than a pencil.
They arrived bundled in wet burlap inside cardboard boxes that smelled of damp soil and pine shavings.
They cost a little more than $300.
Opal paid with money she had saved from 2 summers of detasseling corn.
The seedlings arrived in April 1981.
Opal planted most of them herself.
Her grandmother helped during some afternoons.
A boy from down the road named Kurt Ostrander came on weekends because he had a crush on Opal that apparently everyone knew about except Opal herself.
She did not plant the trees in straight north-south rows, as someone might have done with a traditional shelterbelt.
Instead, she used long curving lines following the contours of the ground.
One of the Soil Conservation Service pamphlets had described that method for erosion control.
The rows ran perpendicular to the slope.
Each line of trees would function like a low check dam, slowing water rather than giving runoff another channel to follow.
Between the oak rows, Opal seeded switchgrass and little bluestem.
They were native prairie grasses Ruth remembered growing there before the plow had ever touched the land.
Planting took 11 days.
Opal’s hands blistered.
Then they callused.
On the ninth day, light snow began falling.
She kept planting.
When the final seedling went into the ground, the flat had been transformed into 4,000 thin green whips arranged in curving rows.
None reached much higher than a person’s knee.
They were spaced approximately 12 feet apart.
From the county road, they looked like almost nothing.
A mistake.
A 17-year-old girl who had spent a summer’s wages planting something on ground everyone already knew was worthless.
The talk began before the seedlings had fully leafed out.
Most mornings, men gathered at the grain elevator to weigh loads and exchange the kind of conversation that often passed for weather forecasting in rural Nebraska.
Someone asked Dale Vance what his daughter was doing on the flat.
Dale, slightly embarrassed and defensive, explained that she was planting trees.
The laughter that followed was not openly malicious.
It was simply the laughter people used for something they had already decided did not deserve serious thought.
Someone suggested Opal should have planted Christmas trees.
At least those might be worth something in 10 years.
Another man said the flat had defeated better farmers than a 17-year-old girl carrying a coffee-can rain gauge.
Dale had little to say.
He paid for his fertilizer and left.
The first 2 summers tested both Opal and the trees.
The drought of 1981 killed nearly 600 seedlings.
Opal replaced every 1 of them that November, driving a dibble bar into stony hardpan until her shoulders ached.
During the winter of 1982, rabbits entered the rows and gnawed the bark from another 200 trees.
Ruth suggested wrapping the young trunks in mesh.
The work consumed 3 full weekends.
The switchgrass between the rows emerged unevenly and sparsely during the first year.
By the second year, it grew thicker.
By the third summer, it had knitted itself into a low green mat.
For the first time in approximately 50 years, something was holding the soil on the flat in place.
No one passing on the road noticed that part.
Grass was not what people had been laughing at.
By 1984, the bur oaks stood about waist high.
The mockery had become quieter.
It was no longer necessarily a joke people told aloud.
It had hardened into something they simply believed about the Vance girl.
She was odd.
She had wasted good money on bad land.
Her father should have stopped her when he had the chance.
Kurt Ostrander’s father told him to quit helping her.
He said working on Opal’s project sent the wrong message about what a serious farming operation looked like.
Opal continued anyway.
Part 2
Opal kept the green notebook.
She continued recording rainfall.
She also began measuring how quickly water entered the soil with a simple ring infiltration test her grandmother had shown her.
She drove a metal cylinder into the ground and timed how long a measured amount of water took to disappear.
On bare portions of the flat outside the planted rows, water remained on the crusted surface for 11 or 12 minutes before it began soaking in.
Inside the tree rows, where switchgrass and accumulating leaf litter covered the soil, the same amount of water disappeared in less than 90 seconds.
Opal recorded both numbers.
She did not tell anyone.
No one was asking.
By 1986, some of the oaks had reached 6 or 7 feet.
Their canopies were only beginning to touch at the outermost tips.
What no one could see was happening underground.
The roots had been driving through the caliche layer that had blocked most other roots on the flat for generations.
The oak taproots opened channels into earth that had effectively been sealed long before Ruth Vance was born.
Those channels gave water somewhere to go.
Then came 1987.
The winter had been dry.
According to the county extension office, it was the driest in 11 years.
Farmers throughout Kuster County prepared for a difficult growing season.
Instead, during the final week of May, 6 inches of rain fell in 18 hours.
A weather system stalled over the region and refused to move.
Older residents compared the rainfall to the storms that had produced the flash floods of 1935.
Creeks that had not carried water in years rose over their banks.
County roads washed out in at least 12 places.
On the Whitlock farm, 2 miles east, 40 acres of newly planted milo disappeared downhill during a single afternoon.
The topsoil went with it.
Where level ground had been that morning, gullies 4 feet deep remained.
The same story played out across open cropland in the county.
Sheet erosion stripped fields.
Culverts clogged with silt.
Fence lines disappeared under mud that had once been somebody’s productive topsoil.
Then Harlon Voss came down the county road.
The same extension conservationist who had mailed Opal the pamphlets 6 years earlier was driving through the region to assess damage for a state erosion survey.
When he reached the edge of the Vance property, he stopped his truck.
He sat there for a long time.
The oak rows were now 7 years old.
Their canopies had begun joining together.
The understory was dense with switchgrass and years of fallen leaves.
The planting had done exactly what its contour design was intended to do.
Rainwater moving downhill from the exposed ground above reached the first line of trees.
Instead of continuing in a destructive sheet, the water slowed.
It spread.
Then it soaked into the soil.
Roots, grass, and accumulated organic material caught the runoff.
The water moved from row to row in a controlled cascade rather than 1 violent rush.
Outside the plantings, exposed portions of the flat showed the same fresh gullies seen on other farms.
Inside the planted acres, there was almost none.
The county road below the flat remained intact along the Vance boundary even though the same road had washed out in 3 other places.
Voss walked Opal’s planting for 2 hours carrying a clipboard.
Then he drove up to the farmhouse and asked Dale if he could speak with his daughter.
Opal was 23.
She still lived at home.
She still managed the flat while doing the rest of the farm work.
When she stepped onto the porch, Voss skipped the pleasantries.
He told her what he had seen.
The state was compiling an emergency erosion assessment for the region.
In 3 counties, the 60 acres Opal had planted were the only ground he had surveyed that had come through the storm essentially undamaged.
He asked how she had designed it.
Opal went into the house.
She returned carrying the green notebook.
It now contained 7 years of observations.
Rainfall totals.
Infiltration times.
Seedling mortality.
Rabbit damage.
Exact spacing between the contour rows.
Opal sat with Voss at the kitchen table for nearly 3 hours and answered his questions.
Ruth made coffee.
She did not join the discussion.
Every so often, she smiled into her cup.
The state survey was published that autumn.
The Vance planting appeared as a case study.
The report described the 60 acres as a successful contour agroforestry erosion-control system and credited the design as one independently developed by a local landowner.
Voss made certain the report named the landowner.
Opal Vance.
Not Dale.
Opal.
By the following spring, the men who had laughed at the grain elevator began driving out to inspect the flat.
They stood beside the county road with their hats pushed back.
Most had little to say.
Men in that part of the world tended to become quiet when they had been wrong about something for a long time.
Kurt Ostrander returned in April.
His father had once told him to stop helping Opal.
Now Kurt asked whether she could use another set of hands.
Another family was putting in a second planting on 40 acres that had been heavily damaged by gully erosion 2 farms away.
Opal said yes.
Word spread the way it often did through farming country.
Slowly at first.
Then almost everywhere at once.
By 1990, 11 contour tree plantings were being established on marginal land across 3 counties.
Most were modeled directly on the 60 acres people had once called the stupidest thing they had seen since someone tried raising ostriches.
Part 3
Opal Vance never left the farm.
In 1991, she married Kurt Ostrander.
During the years that followed, the 2 of them gradually took over the operation from Dale.
The oaks on the flat continued growing.
They reached 40 feet.
Then, over time, approximately 60 feet.
Their crowns closed above the old caliche scar until someone driving along the county road would have had difficulty imagining that bare, cracked ground had ever existed beneath them.
The flat had once been considered the worst 60 acres on the Vance property.
Eventually, it became some of the most valuable.
Not principally because of the timber, although the mature oaks themselves had value.
Its importance lay in what the land now held.
Water that once ran away within an afternoon remained on the property.
Topsoil that had once blown or washed off by the ton stayed where it belonged.
The trees changed the way the ground behaved.
So did the native grasses.
So did decades of leaves decomposing beneath the canopy.
So did the root channels penetrating the hard layer below.
The restoration had not happened because Opal had been certain.
It happened because she kept measuring.
She kept replanting.
She kept recording.
When nearly 600 seedlings died in the 1981 drought, she replaced them.
When rabbits damaged another 200 in 1982, she protected the remaining trees.
When the first-year grass looked patchy, she waited for the second year.
When people laughed, she kept a notebook rather than an argument.
When infiltration inside the planting improved from more than 11 minutes to less than 90 seconds, she wrote the figure down even though no one wanted to hear it.
When the oaks were only waist high and the project still looked foolish from the road, she continued.
By the time the storm of 1987 arrived, the success people saw aboveground had already been developing for years where they could not see it.
Roots had penetrated the hardpan.
Grass had stabilized the surface.
Leaf litter had accumulated.
Water had begun entering the soil instead of escaping over it.
The 6 inches of rain that fell in 18 hours did not create Opal’s success.
It revealed it.
The same storm that stripped other fields exposed what 7 years of patient work had changed on the Vance flat.
Opal is now in her 60s.
She still keeps a notebook.
The newest belongs to a stack of records extending back more than 40 years.
She still walks the tree rows on many mornings before the heat rises.
Her grandmother once walked a porch remembering the black skies of the Dust Bowl.
As a girl, Opal walked a barren flat recording numbers no one else wanted to hear.
Now she walks beneath trees that stand as the visible result of those years of attention.
People sometimes ask what made her so certain when she was 17 and nearly everyone around her believed she had lost her mind.
Opal always gives the same answer.
She had not been certain.
She had simply been paying attention longer than anyone else had bothered to, to ground that had been trying to tell its story for 50 years to anyone patient enough to—
