Texas A&M AquaPlant
is the easiest place online to identify aquatic vegetation common around here. Then you can go to Wired2Fish
and search "vegetation," or the specific plant you're researching, to browse their how-to videos and articles.
Most folks in the fishing circles call vegetation either grass, moss or pads to describe as many as 20 or 30 different species so searching for information on how to fish Illinois Pondweed (Potamogeton illinoensis
) isn't going to do you much good in a fishing article search.
