Participate in macrophyte data collections. Venture out on a boat into a lake, pond or reservoir into waters between 2 and 16 feet deep. This range of depth provides for successful identification of multiple varieties of macrophytes. Proceed into waters at the end of the summer, before the beginning of fall. Due in large part to preferable water temperatures, macrophyte clusters are most healthy and transparent at the end of the summer.
Collect different types of macrophytes from surface water, mid-depth water and water body beds. Use a standard garden rake to sweep macrophytes into your grasp. Place an underwater view scope vertically into the water to locate submerged macrophyte plants. Use a view scope with a 4-inch diameter design and during clear, daylight hours for maximum viewing potential.
Identify your plants based on physical characteristics and the location in the water where they are found. Water lilies, for example, are identifiable by their white buds, green leaves and stems. These plants hover on surface waters near shore lines. Additionally, pickerelwood is identified by their purple blooms and long, green stems. Pickerelwood are found at mid-depth ranges. Most macrophytes with colorful blooms are surface or mid-depth water plants. On the other hand, watermilfoil macrophytes are bushy, fern-like green plants, physical characteristics similar to many submerged macrophytes, rooted at the bottom of water beds.
Place all macrophyte findings into individual plastic bags. Mark all bags with plant identification for future study.
