Erosion Control & Revegetation Planting Guide

Disturbed sites and steep slopes have various soil types and conditions. These site types are often in need of erosion control & revegetation. Site examples include landfills, surface mines, road cuts or construction sites.

HABITAT

Various soils resulting from construction leaving exposed clay, sand and rock outcropping without topsoil; generally occupied with UPL, FACU and FAC species.

FERTILITY

Generally low in fertility; therefore, adding topsoil or organic matter (compost) can be very beneficial. Check your soil pH and select species adapted to that pH. Add lime and fertilizer as recommended by soil analysis. Incorporate amendments into the soil in a manner, such as tracking, that will leave the soil rough and minimize soil erosion and rapid runoff. Fertilizing is not recommended if there is a weed problem.

SEEDING METHOD

Broadcast seed (by hand or machine), drill seed or hydroseed. For areas with slope less than 3:1, cover the seed 1/8”-1/4” deep by dragging with a spring-tooth harrow or firmly press the seed into the soil using a cultipacker, lawn roller or ATV.

SITE PREPARATION

To get started on your erosion control or revegetation project begin by eradicating existing invasive vegetation by having a licensed spray technician apply an approved herbicide. Perennial weeds not addressed before establishment will be difficult to remove later. Whenever possible, regrade the site to reduce slope and build diversions which will reduce erosion and minimize seed loss.

For areas with slope greater than 3:1, final tracking should be perpendicular to the slope as the tracks will help reduce erosion, retain seed and seed moisture.

Mulching with straw, hydromulch or straw/coconut fiber mats is recommended on these sites to protect the seed from drying out or washing away.

GROWING SEASON MAINTENANCE

First Growing Season

  • When feasible, post-planting maintenance (if the ground is not too rough or steep) will provide improved results. Whenever canopy (overall vegetation) reaches a height of 18”-24”, use a brush hog mower or string trimmer to trim the meadow to a height of 8” (Note: A lawn mower is not recommended as the mower height will be too low and native seedlings will be killed). This will reduce competition by fast-growing weeds for sunlight, water and nutrients needed by slow-growing perennial natives.
  • If bioengineering materials are used on the site, mowing should be above the new growth of these materials. Mowing should cease by mid-September.
  • Problem weeds should be hand pulled or spot sprayed with an approved herbicide (such as Roundup®).

Second Growing Season

  • For sites that are not too rough or steep, prior to new spring growth reaching a height of 2” (i.e., shortly after forsythia or redbud blooms), trim any material standing from the previous year close to the ground (approximately 2”). This will allow the soil to warm more quickly, which will stimulate the emergence and growth of native seedlings and reduce the likelihood of the meadow being invaded by shrubs.
  • If bioengineering materials were used on the site or seed of shrubs/trees were part of the mix, the site should not be trimmed after the establishment year.
  • Problem weeds should be hand pulled or spot sprayed.

Special Circumstances

If you notice a heavy infestation of ragweed or foxtail in the second growing season, trim the meadow to a height of 8”. Trimming should cease by mid-September. However, vegetation allowed to grow without mowing provides more protection for wildlife and aids in erosion control.
