Data Collection MethodsNoxious WeedsWe encourage lake residents to conduct annual (or more often) surveys of the aquatic vegetation in their lake. By knowing what normally grows in the lake and where, you can spot new, potentially noxious weeds before they become wide-spread. Early action is much less costly than waiting until the plant becomes well-established. It's best to survey on a calm day in mid-summer. Collecting underwater plants for identification You can collect an underwater aquatic plant by dropping a weighted rake to the bottom of the waterbody and pulling up the plants snagged by the rake. When possible, the entire plant, including roots and flowers or fruits, should be collected. (The flowers and fruits of aquatic plants often stick up above the water in a spike-like arrangement.)
Wetland plants grow in wet areas that may become dry in the summers. Wetland species typically have their roots in the water with most of the rest of the plant emerging above the water. Cattails and skunk cabbage are examples of native wetland plants. Many of the noxious wetland species are tough and robust and do not necessarily need to be kept damp like the underwater species.
Poorly-prepared plants, or plants that sit in hot conditions, often arrive in such bad shape that they can't be identified. |
