What is the main concern regarding wild rice cultivation?

• A. Deeper lakes threaten the growth of wild rice.
• B. Coastal salinity reduces growth.
• C. Overgrazing damages habitat.
• D. Pollution from pesticides harms seed germination.

Answer: (C)

Wild rice thrives in shallow, calm freshwater wetlands where plants create a protective seedbed and stable conditions for germination and growth. The main concern for cultivation is damage to that habitat from overgrazing. When animals graze and trampling occurs, protective vegetation is removed, soil becomes compacted, and sediment is stirred up. These changes reduce light reaching the water, disrupt the seedbed, and make it harder for wild rice to establish and compete. The disturbed habitat also opens space for invasive plants that shade out wild rice, compounding the problem. Because the plants’ success depends on a stable, undisturbed wetland environment, habitat damage from grazing has a larger impact than the other factors listed.
