Correct Answers/ Latest Update / Already Graded
Describe what areas/sites an applicator with the natural area, forestry, and rights-
of-way certification can treat
Ans: Certified to treat vegetation plus emergent vegetation exposed above
water or found in natural areas, forest, and rights-of-way.
Describe the type of work that requires a natural area, forestry, and rights-of-way
certification
Ans: Natural areas, managed to protect existing species, or restore native plant
communities to a more natural state
Right of ways, maintain facilities and structures such as power lines and outages
to prevent possible problems which include power outages
Forestry, THIS DOES NOT INCLUDE ABORICULTURE, but is limited to
silviculture which the establishing and managing of forest.
On a drawing, ID different plant types, such as terrestrial, submergent, floating-
leaved and emergent
Ans: Emergent plants/vegetation are plants that are rooted in the sediment with
most of its parts into above the waterline
Floating plants are plants rooted in the lake bottom, but leaves and flowers float
on the surface.
Submergent vegetation are plants that have stems or leaves growing entirely
below the surface of the water as water levels fluctuate
Terrestrial plants are living or growing on dry land
