Revegetation

BMPs for Revegetation:

  • Reestablish vegetation on temporary roads, drainage systems, side slopes, back slopes, skid trails or landings following significant soil disturbances when natural revegetation will not prevent erosion. See "Revegetating Disturbed Areas" below.
BMPs for Equipment Maintenance and Litter:

  • Perform all maintenance away from riparian areas.
  • Capture all coolants, oils, fuels, etc. and dispose of waste properly.
  • Repair leaks immediately.
  • Properly dispose of all trash associated with harvesting. DO NOT burn or bury.

Revegetating Disturbed Areas: Recommended Specifications

Site & Seedbed Preparations

  • All disturbed areas with a grade of 5 percent or greater and/or which are subject to excessive erosion should be seeded within the first 15 days of next seeding season after construction as weather permits. These steep grades and any other area with a high erosion potential (such as sets, skid trails and haul roads) should be identified as soon as the operation is completed.
  • Water control measures and/or shaping of the land should be completed as the operation is finished to guarantee the stability of the site until a ground cover becomes established.
Seeding
  • Selected seed mixture may be broadcast or drilled. Seeding is usually more successful in the spring and fall. Broadcast seed can be covered by dragging a chain, brush, disk or harrow; firming with a roller or cultipacker; or by drilling to ensure seed contact with the soil (0.5-1 inch deep). Permanent grasses may be seeded or sprigged into dead cover provided by temporary cover plants. A long-term perennial, fine-rooted seed mixture should be used for most effective erosion control.
  • The objective of seeding is to quickly establish a ground cover that will hold the soil together under most conditions. Seed selection should consider the season, the soil type, the availability of sunlight to the area to be seeded and the cost of the seed. To get the desired results, a combination of seeds may be required.
  • Adapted plants — See the table below, "Seed for Revegetation in Louisiana," for a list of plants and their adaptation by soil types.
  • Planting rates and dates — See the table below "Revegetation – Planting Information."
  • When temporary cover plants such as annual, cool-season crops are used, a follow-up to determine the need for permanent vegetation is needed.
  • Legumes should always be used in mixes with grasses.
  • Sprigging methods — Sprigged plants such as Bermuda grass can be planted by sprigging either by hand or machine or broadcasting the sprigs and then disking and firming with a roller.
  • Fertilizing — Apply 600 to 650 lbs. of 13- 13-13 (or its equivalent) per acre ( these rates are double normal rates) and either mix into the top 2"-3” during seedbed preparation or at the time of planting. Care should be taken to insure that the fertilizer does not enter a stream. To avoid stream contamination, it is recommended that fertilizer not be applied within the streamside management zone. On small areas, fertilizer may be broadcast manually with a spreader prior to or at the time of seeding.
