The interface between land and (big) water

• Lakes, streams, ponds and rivers
• Includes (native) terrestrial and emergent

vegetation

Shorelines:

Shorelines:

Shorelines:

Similar “shoreline” conditions can

• ften occur in:
• Ditches or grass waterways
• Wetlands, bogs or fens
• Floodplains

Shorelines:

The interface between land and water

Shoreline Vegetation's Functions:

Provides protection to the Waterbody

• Reduces surface runoff
• Captures contaminates

The interface between land and water

Shoreline Vegetation's Functions :

Provides protection to the Land

• Absorbs summer wave energy
• Flood control
• Mitigates ice impacts

The interface between land and water

Shoreline Vegetation's Functions :

Provides protection to Wildlife

• Terrestrial Corridors (ag areas)
• Water Access (for drinking or cleaning)
• Offspring Protection (terrestrial and aquatic)

 Vegetation control goals

• Site prep- Shoreline restorations
• Native species enhancement- Habitat improvement
• Specific habitat creation- Pollinator habitat
• Noxious weed control- Applicable laws
• Woody species control- Improved site lines
• Recreational access- Beaches and docks

Shoreline Vegetation Management

 IPM

• May be more important in shorelines areas than

it is in any other environment.

• Drinking water
• Wildlife uses
• Recreation
• Human food sources

Shoreline Vegetation Management

 Herbicide applications

• Where are you planning to apply?
• Terrestrial
• Emergent
• Floating leaf
• Submergent

Shoreline Vegetation Management

This is essential to determine IF you can make the application, and WHAT you need to use.

 Herbicide applications

• Where are you planning to apply?
• Allowed in Cat J
• Terrestrial
• Emergent
• Not allowed in Cat J
• Floating leaf
• Submergent

Shoreline Vegetation Management

 Herbicide applications

• What are you going to apply?
• Terrestrial areas
• Any type of plant not in open water at the time
• Also in a location where drift/overspray cannot contact open

water

• Wind, direction of spray, etc
• Pesticides labeled for terrestrial sites should be used

Shoreline Vegetation Management

 Terrestrial Herbicide Applications

• Non-aquatic pesticide labels may allow limited applications to

areas where limited surface water is present.

• Water created by management activities such as tire ruts.
• Direct applications to snow/ice (“surface water”) is prohibited,

though direct applications to cut stump may be allowed

Shoreline Vegetation Management

 Herbicide applications

• What are you goingto apply?
• Emergent areas
• Any type of plant found in open water at the time
• Or plants in a location where drift/overspray could

contact open water

• Pesticides labeled for aquatic sites MUST be used

Shoreline Vegetation Management

 Includes seasonally or temporarily flooded areas

Shoreline Vegetation Management

 Aquatic Herbicide applications

• Know what the label allows and/or requires
• Some product labels include both terrestrial and aquatic uses

Shoreline Vegetation Management

 Aquatic Herbicide options

• Non- selective- glyphosate, diquat
• Selective- 2, 4-D, triclopyr, dicamba, etc

 Plan for the unexpected

• If potential for standing water exists, plan to use something

labeled for both to avoid delays during the application.

 Shoreline Herbicide Applications

• Know what the label allows and/or requires
• Read carefully both the “Directions for Use” AND

“Environmental Hazards” sections.

• Keep in mind certification requirements if you will be

making applications directly to the water- Category F

Shoreline Vegetation Management

 Herbicide application methods

• Spray- best for site prep and broad application of

selective herbicide, or spot spraying to reduce impacts.

• If using on emergent vegetation, spray toward shoreline, not

into waterbody

• Wick- avoid drift or off-target concerns
• Granular (into the water)-

Not Allowed in Cat J

Shoreline Vegetation Management

 Other considerations

• Permitting.
• DNR permit needed

when controlling emergent vegetation

• Check with the County or
• ther local municipalities

for additional requirement

Shoreline Vegetation Management

 Other considerations

• Recreational Use
• Plan your applications

accordingly to avoid conflicts with swimmers, boaters, hunters, fishermen or other recreational users of the resource.

Shoreline Vegetation Management

 Other considerations

• Species ID: shorelines contain many lookalikes.
• Native verses hybrid cattail species
• Reed canary grass and Canada bluejoint
• Buckthorn species and alder
• Blue flag and yellow flag Iris

Shoreline Vegetation Management

 Other considerations

• Soil disturbances
• These applications often occur in very

sensitive areas with saturated soils.

• Avoid rutting or adversely impacting the soil

and non target vegetation

Shoreline Vegetation Management

 Unfortunately,

**IT happens

Shoreline Vegetation Management

 Other considerations

• Public Perceptions
• Minnesotans take their water very seriously!
• Know what you are doing, what you are

using and why!

• An applicator making a concerted effort to

use the smallest quantity of the safest herbicide possible, helps give the public confidence in the professionalism of our industries.
