Introduction

• Typical issues with roadsides

in West Virginia

– Rock falls

– Bare slopes

– Erosion

– Poor vegetative growth

• Factors leading to issues

− Variability in soil type and

quality

− Various elevation changes

− Steep slopes

Introduction

• National Pollutant Discharge Elimination System

(NPDES) permit

– Requires 70% average vegetated cover for permit to

be released

• Currently, little follow up exists on the long term

vegetation establishment

Objective: Determine the effectiveness of current

reclamation methods at roadside and median locations of

highways in West Virginia.

• Improve reclamation practices to provide better

vegetative cover to prevent erosion and unvegetated

slopes

• Capture a wide range of locations:

- Medians

- Soil types

- Seed mixtures

- Slopes

- Aspects

- Climates

Methods: Roadsides and medians were sampled

between 17 June and 8 August, 2014, and 9 July

and 10 July, 2015.

Methods: Data Collection

• Vegetation Cover

• Slope

• Aspect

• Location and Elevation

• Compaction

• Soil Sample

– Subplot selection

• Randomly selected using methods adapted from

Elzinga et. al. (1998).

– Percent cover evaluated with a 1m x 1m grid

– Portable point frame was composed of 100

intersections

• Slope

– Steepness of each site was

measured with a Suunto PM-5

Clinometer

• Aspect

– Slope exposure determined using a

Suunto A-10 Recreational Compass

– Measured using a Garmin etrex 20

handheld GPS

• Compaction

– Compaction tests performed using agraTronix Soil

Compaction Tester

• Penetrometer complies to ASAE S313.3

• Soil Sample

– Soil samples were collected following procedures by

West Virginia University Soil Testing Laboratory

(2007) for lawn and turf.

– Soil samples analyzed for pH,

nutrients, minerals, and texture

Methods: Cover Classes

• Sites are required to have 70% cover in order to be

released from NPDES permit.

– Cover classes help easily identify sites that have

adequate vegetative cover.

• Aid in determining the effectiveness of WVDOH’s site

reclamation procedures.

• Cover Class Ranges:

– Class I (0-50%)

– Class II (50-70%)

– Class III (70-90%)

– Class IV (90-100%)

Results:

Cover Class I

− Class I (0-50%)

Results: 30% of the sites examined in this study had

excellent mean cover of greater than 90%.

Results: 24% of the sites examined in this study had

poor mean cover of less than 50%.

Results: Common species included tall fescue and

*Parameter shows no correlations to long term vegetative establishment between cover classes

• The worst performing locations had low levels of OM and

high levels of SS.

• Nitrogen was the only macronutrient found to have a

positive correlation to vegetation cover

• pH had no linear correlation, but sites with soils within

optimal pH range had greater cover.

Conclusions:

• Establishing long-term vegetation cover is difficult due to

poor soil and site conditions.

• These results concluded that challenges faced at time of

establishment continue long term.

• 30% of the sites had excellent mean cover (>90%); 24%

percent of the sites were poorly covered (<50%).

• Only 55% of observed sites met the required 70% cover.

Conclusions:

• High soluble salt levels and low fertility were present at

sites with low vegetation.

• Crownvetch was not observed at locations with high

soluble salts, leading to poor mean vegetation cover.

• The most observed species, tall fescue (Festuca

arundinacea) and crownvetch (Coronilla varia L.), are

considered invasive but provided the majority of ground

cover.

Crownvetch Tall Fescue

Recommendations:

• Proper seedbed preparation should be a high priority

• Continued maintenance should be required to overcome

initial challenges

• Soil testing should be mandatory due to expense of

mitigating pH levels.

• Site specific seed mixtures may lead to improved

revegetation success.

help and support throughout the duration of the project.

• No difference between treatments

• Biotic Earth and ProGanics likely took longer due to field

application over the seed

• Long term no effect between applications and method

Field Study Conclusions:

• Objective 1

– At 846 ft., Mowable Areas, Warm Season, Cool

Season, and High Elevation performed as well or

better than current DOH mixtures

– Native mixtures slower to germinate

• Objective 2

– Cool Season and Mowable Areas did as well as the

DOH mixture

– After 90 days, the Warm Season and High Elevation

mixtures have not yet made the 70% cover target

– Difficult to make a warm season mixture perform well

in comparison to a cool season mixture

Field Study Conclusions:

• Objective 3

– After 90 days, there was no difference between seed

bed preparations

• Objective 4

– All treatments achieved 96% cover by 90 days

– Initial germination took longer for Biotic Earth and

ProGanics due to product thickness and not

incorporating seed mixture into the products

– Site conditions were moderate where poor conditions

could show a larger difference between treatments

Recommendations:

• Utilize Mowable Areas and Cool Season mixtures for

high elevations

• Large scale research on seed mixture performances

• Examine soil amendment and media products in large

scale on severe site conditions

• Examine larger selection of HECP on erosion control

effectiveness
