Video summary

Communities across North America frequently face the devastating impacts of severe weather, including flooded streets and washed-out fields, yet a more natural solution often goes unnoticed: native prairie grasses. These plants, once widespread across the continent, serve as a powerful defense against flooding by acting like a natural sponge that can absorb significant rainfall. In stark contrast to these healthy ecosystems, landscapes stripped of their original vegetation cause water to rush away in torrents rather than soaking into the ground. Historical data from major US river basins reveals that runoff has increased hundreds of times compared to the prairie-covered landscapes of the 1800s, demonstrating how the loss of native plants prevents water from infiltrating the earth and instead allows it to tear across the surface, carrying away valuable soil, nutrients, and fertilizers. The restoration of native grasses fundamentally changes how water behaves within an ecosystem, allowing it to seep into the ground and recharge underground reserves while simultaneously reducing flood risk at the surface. This approach is championed by a rancher with fifty years of experience who arrived in 1976 to find land that had been converted from dairy farming and subsequently overgrazed by homesteaders accustomed to different rainfall patterns. These original rangelands were managed for season-long grazing, which led to the overutilization of the native plants. By restoring these specific native species, the rancher has observed a profound shift in hydrology, defined as the movement of water through the soil profile beneath their feet. The primary goal is to ensure that water stays where it falls whenever the ground is not frozen, maximizing infiltration to support plant growth and ecosystem health. Keeping water in place benefits not only the immediate vegetation but also downstream communities by preventing excessive runoff that could lead to flooding elsewhere in the watershed. When the soil is healthy and covered with restored prairie grasses, plants can access the moisture they need to thrive, creating a resilient environment that supports biodiversity and agricultural stability. The rancher emphasizes that while it is impossible to capture 100% of rainfall due to seasonal factors like frozen ground, the focus must be on maximizing absorption during periods when the earth is thawed. Ultimately, this strategy highlights that some of the best solutions for protecting our land and water are those provided by nature itself, urging a return to prairie restoration to safeguard both local ranches and broader watersheds from the increasing threats of extreme weather events.

Every year, communities brace for it. Flooded streets, washed out fields, and rivers spilling over. But are we overlooking a more natural way to slow the surge? Native prairie grasses, once widespread across North America, are more than just scenery. They're a powerful line of defense against flooding. Just one fact says it all. Healthy native grasslands can absorb an 8-in rainfall like a sponge built by nature. In contrast, land stripped of prairie sends water rushing away in torrents. Studies of major US river basins show that runoff has increased hundreds of times compared to the prairie-covered landscapes of the 1800s. Without native vegetation, water no longer soaks in. It tears across the surface, taking soil, nutrients, and fertilizers with it. But when native grasses are restored, water behaves differently. It seeps into the earth, recharging underground reserves, >> [music] >> and reducing flood risk at the surface. Sometimes, [music] the best solutions are the ones nature gave us in the first place. To protect our land and our water, we must bring the prairie back. My 50 years on this ranch have been a lifetime of learning. Uh Garnet and I came here in [music] 1976 uh to a ranch that had been part of a dairy farm. And uh of course, if you know anything about dairy farms, that they [music] tend to have a different management practice than what we enjoy today. The prairies that >> [music] >> we inherited tended to be overgrazed. Uh partly due to the management that they only knew. Some of them were homesteaders that came here from parts of the world where grass was short, and they got plentiful rainfall. But our ecosystem was different, and so what we inherited tended to be overutilized uh rangelands >> [music] >> that uh were accustomed to uh season-long grazing. The native plants [music] that we have restored uh have been really uh beneficial [music] to the ranch and to the whole ecosystem. Uh in particular, we've noticed the change in the hydrology. So, hydrology is the movement of the water through the soil profile. The soil profile being the land that's underneath my feet. My goal is for that water to stay where it falls. Now, we know we're not going to capture 100% of it because there are times of the year when the ground's [music] frozen. And so, there's very little infiltration of the water into the soil profile. But when the ground [music] isn't froze, that's when we want to make sure that we capture as much as possible because the plants depend on it. And some plants require more water than others. But the bottom line is all plants require [music] water to grow. And so, if we can keep them healthy by keeping the water in place of where it falls, the whole ecosystem benefits. Not only does the plant that's under my feet benefit, but so does downstream. Because if we didn't capture that water and it became runoff, it will [music] create problems with flooding somewhere in the watershed.
