What role do native plants play in maintaining spring health?

Stabilizing Soil and Preventing Erosion

Native plants have deep root systems that hold soil in place, preventing erosion and preserving the integrity of the water source. For example, the root system of a sedge plant can extend up to 6 feet in depth, providing a stable network of roots that prevent soil from being washed away by spring rains. In contrast, non-native plants often have shallow root systems and may not provide the same level of soil stabilization.

Absorbing Excess Nutrients

Native plants also play a crucial role in absorbing excess nutrients from the soil, which can help to prevent overgrowth and keep water quality high. For instance, some native plants are able to absorb up to 90% of excess phosphorus from the soil, preventing it from entering nearby water sources. This is particularly important for maintaining healthy water quality in springs, which are often the primary source of water for nearby ecosystems.

Preserving Water Quality

In addition to stabilizing soil and absorbing excess nutrients, native plants also help to preserve water quality by preventing the growth of invasive species that can clog waterways and alter the natural flow of water. For example, native aquatic plants like cattails can help to filter out sediments and nutrients from the water, maintaining its clarity and quality. By preserving the natural balance of the ecosystem, native plants play a vital role in maintaining the health and integrity of spring water sources.
