RIPARIAN SITES are usually adjacent to rivers and waterways. Soils often contain clay, high amounts of organic matter, and/or saturated sand.
Examples of RIPARIAN SITES:
- River and stream banks
- Damp flood plains of rivers and streams
Eradicate existing vegetation by having a licensed spray technician apply an approved herbicide, such as glyphosate (Rodeo?) or a similar aquatic herbicide formulation, to control undesirable vegetation. CAUTION: Some persistent species, such as purple loosestrife, phragmites, or reed canary grass, may need multiple applications of glyphosate. Before seeding, excess dead vegetation should be burned or turned under if conditions permit. Newly constructed riparian sites should be seeded as soon after construction as possible.
Habitat: Riparian sites generally vary from partial shade to full sun. These areas are often subject to flooding.
Fertility: Due to the potential for water contamination, the use of lime or fertilizer in riparian areas is not recommended. We do recommend the addition of organic materials when topsoil has been depleted or removed. Check your soil pH and select species adapted to that pH.
Seeding Method: Hand seed, broadcast, or hydroseed.
Grassy weeds or persistent perennials can re-establish in this type of soil. Monitoring weeds and mowing is essential in the first and second years. Burning (by experienced professionals) about every three years in early spring can prevent shrub invasions.
