A soil erosion problem has been greatly reduced or eliminated
What is this?
When soil is not held in place by plant roots, water can carry a surprising amount of it off the land into streams and lakes where it causes problems. If you see gullies, channels or other bare soil, in most cases you’re looking at soil erosion. Construction sites and farm fields are notorious for erosion due to the amount of exposed soil. Streambanks and the shorelines of lakes and ponds are also particularly vulnerable. Other sensitive spots include downspouts, sump pump outlets and other areas of concentrated water flow. Any slope with exposed soil is a trouble spot.
How do I do this?
On my own
- Some erosion problems are fairly easy to resolve with, for instance, deep-rooted plants, while others are complex. Some even require structural engineering.
- Much depends upon the type of soil, how steep the land is, the water source and volume, and plants.
- If a large amount of land drains through your property – especially if it’s in a concentrated channel – you undoubtedly have additional factors to consider.
- Start by looking for bare soil and sites of erosion on your property. Shorelines, streambanks and hillsides are particularly vulnerable, but any place with a concentrated flow of water might exhibit erosion, including sump pump outlets and downspouts.
- During heavy rain or snowmelt, get your galoshes out and take another look at your property – you will learn quite a bit more about your situation.
- Sometimes, the simplest line of defense is to plant native flowers, grasses and/or sedges suitable to your site. You may need to choose species that are able to thrive under both wet and dry conditions, depending on the factors leading to your erosion.
- Recommended plants for drainage swales include:
Sweet flag (Acorus calamus)
Tussock sedge (Carex stricta)
Fowl manna grass (Glyceria striata)
Sneezeweed (Helenium autumnale)
Sweet grass or Vanilla grass (Hierchloe odorata)
Obedient plant (Physostegia virginiana)

- Consider installing rain gardens and bioswales to reduce the velocity or volume of water flow.
- Consider products such as the following:
- If the area is sloped and/or seed is used rather than young plants, a cover crop of common oats and/or annual rye can help to quickly stabilize the soil.
- Try not to disturb additional ground while installing erosion control features as you may cause even more erosion. Instead, to the degree possible, try to work within the already disturbed channel.
