    Middle Mill by Sivi Sivanesan

    This stretch of the river has three cornered garlic and Himalayan balsam and Japanese knotweed. Also why is loosestrife classed as invasive, we aren't in the USA, its a native in Britain. The same issue with nearly all of the other "invasives" listed. Our sites are in the UK, we need the UK invasive species listed here, not natives. Insect seen = Damselfly larvae
