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
2
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
3
Objective: Determine the effectiveness of current
reclamation methods at roadside and median locations of
highways in West Virginia.
4
• 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.
5
Methods: Data Collection
• Vegetation Cover
• Slope
• Aspect
• Location and Elevation
• Compaction
• Soil Sample
6
Methods: Data Collection
• Vegetation Cover
– Subplot selection
• Randomly selected using methods adapted from
Elzinga et. al. (1998).
7
Methods: Data Collection
• Vegetation Cover
– Percent cover evaluated with a 1m x 1m grid
– Portable point frame was composed of 100
intersections
8
Methods: Data Collection
• Slope
– Steepness of each site was
measured with a Suunto PM-5
Clinometer
• Aspect
– Slope exposure determined using a
Suunto A-10 Recreational Compass
• Location and Elevation
– Measured using a Garmin etrex 20
handheld GPS
9
Methods: Data Collection
• Compaction
– Compaction tests performed using agraTronix Soil
Compaction Tester
• Penetrometer complies to ASAE S313.3
10
Methods: Data Collection
• 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
11
Methods: Cover Classes
12
• 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:

• 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:
30
• 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:
31
• 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:
32
• 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.

Objective 4 Results Eight Days After Planting:
• No difference between treatments
• Biotic Earth and ProGanics likely took longer due to field
application over the seed
130
Objective 4 Results Ninety Days After Planting:
• Long term no effect between applications and method
131
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
132
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
133
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
