In May 1934, dust storms carried topsoil from the Great Plains all the way to Washington, D.C. Ships 300 miles out in the Atlantic reported dust on their decks. Somewhere in the aftermath of those storms, a Russian-born forester named Raphael Zon was called to the capital for consultation.
Zon had been making this argument for years. Born in Simbirsk, Russia, in 1874, he had studied shelterbelts on the Russian steppes before emigrating to the United States in 1898. He earned a degree in forest engineering at Cornell and rose to direct the Lake States Forest Experiment Station in St. Paul, Minnesota. From that post, he had spent more than a decade advocating for what worked on the steppes: rows of trees planted as windbreaks, slowing the wind, holding moisture, protecting crops. The science was sound. The institutional interest was absent. His years of forestry work in the Midwest had brought him into close contact with the suffering caused by periodic droughts, but nobody with the power to act had been persuaded.
The Dust Bowl changed that. Out of Zon's Washington consultations grew what Franklin Roosevelt would call, on multiple occasions, "my baby." In the summer of 1934, Roosevelt allocated $15 million from emergency relief funds for the planting of forest protection strips across the Plains. The vision was enormous: a belt of trees 100 miles wide, stretching 1,200 miles from the Canadian border through the Texas Panhandle. The full program was estimated to cost $75 to $100 million over twelve years.
The funding mechanism mattered. Roosevelt did not go to Congress first. He used emergency appropriations, the kind of improvised fiscal channel that the New Deal ran on. When the Comptroller General objected in September that Congress had not authorized a project requiring years of future financing, the immediate funding was limited to $1 million drawn from drought relief appropriations. The legal basis for the work itself rested on the Clarke-McNary Act of 1924, which authorized federal cooperation with states on forestry.
Roosevelt had the vision and Zon had the science, but Congress wanted no part of either.
"The Most Ridiculous and Silly Proposals"
The opposition came from multiple directions at once, and not all of it was unreasonable.
Professional foresters recognized that unsuitable terrain and soils would force breaks in the belts. Some objected to spending money on woodlands that might produce fence posts and firewood but not commercial timber. Agricultural interests worried about diverting prairie farmland from crop production. And many people, inside and outside the scientific community, remembered the Timber Culture Homestead Act of 1873, which had offered free land to settlers who planted trees on the Plains. It had failed spectacularly, producing abandoned homesteads across the region and reinforcing the suspicion that trees and grassland didn't mix.
Behind that suspicion lay a deeper one. Nineteenth-century boosters had promoted the pseudo-scientific claim that "rain follows the plow," insisting that settlement itself would change the climate of the arid West. The idea had been thoroughly discredited, but Zon's proposal carried an uncomfortable structural resemblance to it. He was arguing that planting trees would change wind patterns, reduce evaporation, and ameliorate drought conditions. The scale of the claim invited skepticism from people who had watched similar promises collapse within living memory.
Within the Forest Service itself, the project was contested. On May 28, 1934, three Forest Service researchers — Carlos G. Bates, Harold R. Scholz, and Joseph H. Stoeckeler — wrote directly to Zon with their objections. The full content of that letter is preserved in Wilmon Droze's 1977 history Trees, Prairies, and People but has not been widely reproduced. What is clear from the broader record is that the debate was genuine. Even those in the forestry profession were divided on feasibility.
Zon responded publicly. His 1935 article in Science bore a title that captured the terms of the argument: "Shelterbelts — Futile Dream or Workable Plan." The phrase "futile dream" was his critics' language. He was fighting for the program's legitimacy in a peer-reviewed journal while the first trees were being planted.
Roosevelt, aware that his full vision had no chance, scaled back his Congressional request to just $1 million.
Congress said no.
The Appropriations Fight
In the spring of 1936, the 74th Congress took up the shelterbelt in the House agriculture appropriations bill. The debate was not close. Rep. Lloyd Thurston, Republican of Iowa, expressed what was described as widespread House sentiment:
"One of the most ridiculous and silly proposals that was ever submitted to the American people."
After the $1 million request died, Rep. Phillip Ferguson, Democrat of Oklahoma, tried to secure $180,000 for the program. He failed by a wide margin. The final appropriations bill provided roughly $170,000, earmarked not for planting but for liquidating the project.
The shelterbelt was, by any conventional legislative measure, dead.
It survived anyway. Roosevelt had launched the program before Congressional approval using the same emergency channels that birthed it. When disputes arose over whether a long-term project qualified for emergency relief funding, Roosevelt transferred the program to the Works Progress Administration in 1937. It was renamed the Prairie States Forestry Project. With WPA funds and labor, it continued. Paul Roberts, the Forest Service employee who administered the program from Lincoln, Nebraska, kept planting.
The funding workaround remade the program entirely.
What the Workaround Built
Roosevelt's original vision had been for publicly owned windbreaks on a massive scale. The Forest Service initially tried to buy land from farmers at low cost for the plantings. Farmers did not respond favorably.
The shift to WPA funding, combined with the cooperative framework required to work on private land, produced a fundamentally different model. Farmers donated strips of land, prepared them for planting, agreed to fence the trees against livestock, and provided cultivation during the first two to four years. The Forest Service supplied the trees, arranged planting, and provided expertise on species selection and care. The first year was devoted largely to preparation and species trials, planting native varieties like red cedar and green ash along fence rows.
This was, as University of Nebraska researchers David and Sarah Karle noted in their comprehensive analysis, unusual for a New Deal program: federal funding for conservation work on private land, using unproven agroforestry methods, in a region where the science was actively contested.
The cooperative structure meant that farmers who participated had a stake in the trees' survival. They were tending windbreaks on their own farms, protecting their own fields. The knowledge of which species survived, which spacing worked, which soil conditions demanded different approaches accumulated at the household level, in the daily observations of people who walked their land every morning.
What the Opponents Got Right
Some of the scientific skepticism was warranted. The grassland ecology of the Great Plains was not the Russian steppe, and the question of whether trees belonged there was legitimate. The agronomic alternatives that critics preferred — low-till and no-till farming, crop rotation, planting grasses — eventually became the dominant approach to soil conservation on the Plains. In 1942, the Soil Conservation Service took the shelterbelt program from the Forest Service and emphasized county- and farm-level work over the regional vision Zon had championed.
The Congressional opponents had procedural ground to stand on, too. A president using emergency relief funds to launch a multi-decade conservation program without legislative authorization raised genuine questions about executive power and fiscal responsibility. The Comptroller General's objection was sound. Thurston's rhetoric was overheated, but the underlying concern about a program that bypassed normal appropriations was shared across party lines.
The program planted over 190 million trees in nearly 19,000 miles of shelterbelts across 33,000 farms in six states, at a final cost of less than $14 million. The survival rate climbed to 82 percent.
By the time the program ended in 1942, terminated by wartime labor shortages, it had planted over 190 million trees in nearly 19,000 miles of shelterbelts across 33,000 farms in Nebraska, Kansas, Oklahoma, Texas, and the Dakotas. Forestry officials surveying the results in 1944 estimated that well-tended trees would survive for thirty to sixty years.
A federally owned shelterbelt stretching from Canada to Texas would have required massive land acquisition, ongoing government maintenance, and sustained Congressional funding for decades. The cooperative model that emerged from the wreckage of the appropriations fight operated on entirely different terms. It asked farmers to contribute labor and land. It gave them trees and expertise. And when the WPA ended and the Forest Service moved on and the Soil Conservation Service reorganized the work again, the trees were still standing on private land, tended by the families who had planted them, in rows running north-south across thousands of farms from the Dakotas to the Texas Panhandle. Whether they kept standing was no longer a federal question.
