When people think about protecting water quality, they often think about storm drains, rivers, or wastewater treatment plants.
But one of the most effective tools for improving water quality may be growing right outside your door.
Native plants help slow stormwater, reduce pollution, prevent erosion, support wildlife, and improve the health of our local waterways. Whether planted in a rain garden, along a shoreline, or throughout a landscape, native plants are an important part of green infrastructure.
What Are Native Plants?
Native plants are species that naturally occurred in a region before widespread development and landscaping introduced plants from other parts of the world.
Because they evolved in Nebraska’s climate, native plants are well adapted to:
- Local rainfall patterns
- Temperature extremes
- Drought conditions
- Native soils
- Local wildlife and pollinators
Examples include many native grasses, wildflowers, sedges, and shrubs commonly found throughout Nebraska’s prairies and wetlands.
How Native Plants Improve Water Quality
Deep Roots Help Water Soak In
Many native plants develop root systems that extend several feet into the ground.
These deep roots create pathways that allow water to infiltrate the soil rather than running across the surface.
More infiltration means:
- Less runoff
- Less erosion
- Reduced flooding
- More groundwater recharge
Native Plants Filter Pollutants
As stormwater moves through vegetation, plants and soil help trap:
- Sediment
- Nutrients
- Trash and debris
- Some pollutants attached to soil particles
This natural filtering process helps keep contaminants out of lakes, rivers, and streams.
They Reduce Soil Erosion
Plant roots help hold soil in place.
Without vegetation, rain can wash exposed soil into streets, ditches, and waterways, contributing to sediment pollution and reducing stormwater system capacity.
Native plants provide year-round protection against erosion, especially in areas prone to runoff.
They Often Require Less Fertilizer and Water
Because native plants are adapted to local conditions, they generally require fewer inputs once established.
This can mean:
- Less irrigation
- Less fertilizer
- Less pesticide use
- Reduced maintenance
Using fewer chemicals reduces the likelihood that excess nutrients and pollutants will be washed into local waterways.
Native Plants and Wildlife
Native landscapes provide habitat for:
- Bees
- Butterflies
- Birds
- Beneficial insects
- Other wildlife
Healthy ecosystems often support healthier waterways because vegetation helps stabilize soil and improve water quality.
Where Native Plants Can Be Used
Native plants can be incorporated into landscapes of almost any size.
Common locations include:
Rain Gardens
Native plants are ideal for rain gardens because they can tolerate both wet and dry conditions.
Shorelines and Pond Edges
Vegetated buffers help filter runoff before it reaches the water.
Yards and Landscaping
Even replacing a small section of turf grass with native plants can improve infiltration and provide habitat.

Native plantings can reduce maintenance while improving water quality and supporting pollinators.
Why Some Areas Look “Less Manicured”
Many communities are intentionally allowing native vegetation to grow in certain locations.
While these areas may appear less maintained than traditional turf grass, they often serve an important purpose:
- Filtering runoff
- Stabilizing shorelines
- Reducing erosion
- Supporting wildlife
- Improving water quality
Sometimes a little extra vegetation is actually part of the solution.
What You Can Do
You don’t need to replace your entire yard to make a difference.
Consider:
- Planting native flowers and grasses in landscape beds
- Adding native plants to a rain garden
- Maintaining vegetated buffers near ponds or waterways
- Reducing fertilizer use where possible
- Learning which native species thrive in your area
Even small planting projects can help improve water quality and reduce runoff.
Why It Matters
Every rainfall event creates an opportunity for water to either run off or soak in.
Native plants help keep water where it falls, reduce pollution, prevent erosion, and support healthy ecosystems.
By incorporating native vegetation into neighborhoods, parks, and private landscapes, communities can improve water quality while creating beautiful spaces that benefit both people and wildlife.
Sometimes the best stormwater infrastructure doesn’t look like infrastructure at all—it looks like nature.
