Vegetation and Revegetation Techniques Flashcards

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

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

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.

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

Answer: Annual ryegrass or cereal rye

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.

Permanent seeding differs from temporary seeding in that it:

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

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.

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

Answer: Lime and fertilizer based on soil test results

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.

Hydroseeding combines seed with:

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

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.

The best time to seed a disturbed site in temperate climates is typically:

Answer: Late summer to early fall or early spring when temperatures favor germination and soil moisture is adequate

Late summer to early fall and early spring provide ideal soil temperatures and moisture conditions for seed germination in temperate climates, maximizing establishment success.
