GAP Ecosystem Restoration 3

Question 1

In GAP-certified operations, which measurement best indicates successful prairie restoration?

Accepted Answer

High native plant species richness and low invasive cover

Answer

Species richness of native plants combined with low invasive cover signals a functionally diverse, self-sustaining prairie ecosystem.

Question 2

What role do mycorrhizal fungi play in agricultural ecosystem restoration?

Accepted Answer

They form root partnerships that enhance plant nutrient uptake and drought tolerance

Answer

Mycorrhizal fungi form symbiotic associations with plant roots, dramatically expanding their effective root surface area and improving uptake of phosphorus and water.

Question 3

Which factor is MOST critical when selecting native plants for a restoration project on a US farm?

Accepted Answer

Choosing local ecotype seed sourced within the same ecoregion

Answer

Local ecotype seeds are genetically adapted to the specific climate, soils, and seasonal cues of the region, giving restoration plantings the best chance of long-term survival.

Question 4

What does the term 'ecological connectivity' mean for farm-based restoration?

Accepted Answer

Linking restored habitat patches so wildlife can move between them

Answer

Ecological connectivity links restored habitat corridors so wildlife populations can disperse, feed, and breed across a fragmented agricultural landscape.

Question 5

According to GAP guidelines, which land area is considered highest priority for riparian restoration?

Accepted Answer

Land immediately adjacent to streams, rivers, or wetlands

Answer

Areas directly bordering waterways have the greatest potential to protect water quality through filtration, bank stabilization, and shade that moderates stream temperature.
