CEPSCI Vegetation and Revegetation Techniques

Question 1

What is the primary function of temporary seeding on a construction site?

Accepted Answer

To provide rapid vegetative cover that stabilizes exposed soil and reduces erosion during construction

Answer

Temporary seeding provides a fast-growing vegetative cover on exposed soils to reduce erosion during construction activities, even though the vegetation will eventually be replaced with permanent cover.

Question 2

Which grass species is commonly used for temporary seeding in the eastern US because of its rapid germination and growth?

Accepted Answer

Annual ryegrass or cereal rye

Answer

Annual ryegrass and cereal rye germinate and establish quickly, making them ideal for temporary erosion control seeding in the eastern United States during cool and transitional seasons.

Question 3

Permanent seeding differs from temporary seeding in that it:

Accepted Answer

Establishes perennial, self-sustaining vegetation intended to remain as the final ground cover

Answer

Permanent seeding establishes perennial vegetation adapted to the local climate that will persist and provide long-term erosion control and final stabilization of the site.

Question 4

What soil amendment is most commonly applied before seeding to improve germination on disturbed sites?

Accepted Answer

Lime and fertilizer based on soil test results

Answer

Soil testing guides the application of lime to adjust pH and fertilizer to provide nutrients, both of which are critical for successful seed germination and establishment on disturbed soils.

Question 5

Hydroseeding combines seed with:

Accepted Answer

Water, mulch, fertilizer, and tackifier sprayed as a slurry

Answer

Hydroseeding applies a slurry of seed, water, mulch, fertilizer, and tackifier that bonds to the soil surface, providing an all-in-one seeding and mulching application.
