Many animals within the park rely on specific types of plants as their sole food source. Monarch butterflies, for example, only lay their eggs on milkweed, and only eat milkweed while in their caterpillar phase. Milkweed requires a moderately acidic soil to grow, surviving in soil pH levels from 4.8 to 6.8.As with most other plants, it cannot tolerate pH levels below 4. Overly-acidic soil prevents roots from being able to absorb water and nutrients crucial for survival.ilkweed requires a moderately acidic soil to grow, surviving in soil pH levels from 4.8 to 6.8.
