Leaving space for native habitat is one of the most important — and most overlooked — land stewardship practices for farms, acreages, and suburban and urban properties.
Iowa is one of the most altered landscapes in the United States, with over 99% of native prairie removed and much of the remaining land converted to row crops, lawns, or development.
When native habitat disappears, the ecological systems that once supported healthy soil, clean water, pollinators, and wildlife disappear with it.
Before settlement, Iowa was dominated by tallgrass prairie, oak savanna, wetlands, and woodlands. These native ecosystems evolved over thousands of years to manage rainfall, build deep fertile soils, and support an incredible diversity of plants, insects, birds, and mammals. The rich soils Iowa is known for today exist because of native prairie root systems that reached many feet below surface and were never disturbed.
When native prairie and habitat are removed, the land loses its natural ability to regulate water, cycle nutrients, and protect itself from erosion.
This is why Iowa struggles with issues like soil loss, nutrient runoff, flooding, and declining water quality.
Leaving space for native habitat helps address these problems at their source instead of relying solely on downstream fixes.
Native Iowa plants play a powerful role in soil health. Deep-rooted prairie grasses and wildflowers improve soil structure, increase organic matter, and allow rainfall to soak into the ground rather than run off into ditches and waterways.
Native habitat also supports pollinators and beneficial insects that the rest of our ecosystems depend on. Native bees, butterflies, birds, and predatory insects rely on native plants for food and shelter throughout the year. These species improve pollination and naturally reduce pest pressure.
Without native habitat, these beneficial species have nowhere to live, and farmers are forced to rely more heavily on chemical inputs.
A common misconception about agriculture is that every acre must be actively producing a crop to be valuable. But ecological value is just as important.
Prairie strips, restored wetlands, and wooded edges all provide measurable benefits to surrounding cropland and wildlife.
Even small amounts of native habitat can significantly reduce soil erosion and nutrient loss while improving overall land resilience.
Leaving space for native habitat does not require a large acreage or huge prairie restoration projects. It can start with small choices such as planting Iowa native perennials instead of turf grass, creating rain gardens, and not using common lawn chemicals. These choices add up across the landscape and create meaningful change over time.
Land stewardship is a long-term commitment. Native habitat does not deliver instant visual results, but it delivers lasting ecological ones. It rebuilds soil, protects water, supports wildlife, and strengthens food systems for future generations.
Leaving space for native habitat is not about doing less with the land — it is about allowing the land to function as it was designed to.
In a state shaped by agriculture, restoring and preserving and restoring native habitat is one of the most powerful ways to care for Iowa’s land, water, and communities.
When we make room for native habitat, we are investing in the health of Iowa for future generations.
