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.

Common Milkweed is an important plant because so many species of insects depend on it. Monarch Butterflies, Milkwee Bugs, and Milkweed Leaf Beetles only eat milkweed, and could not survive without it. Many other species of insects use milkweed as their primary food source, or as a major food source.Common Milkweed grows up to six feet tall.
