You want to help the people out? Start some fish farms. My fish would be the Nile Tilipia, Oreochromis niloticus. You have 100 acres of unused waterways, start building. Create jobs, food source and readily sold export. Invariably some will escape, hopefully they will knock down or limit the yet to be identified plant. Pretty tough to tell, as coontail normally is a lot bushier on the tops. Plus that infamous red stem has milfoil written all over it. Milfoil sends off floaters but is normally rooted. Some plants are very easy to identify, coontail/milfoil are tough to distinguish from photos on the internet. I always support the troops, 4 year US Navy vet during the cold war.
