River fly monitoring and balsam bashing

We went down to Parsonage Bridge today to carry out a Riverfly Monitoring survey and while Hsusin collected samples and then counted the species gathered, I wandered 50 metres up and downstream cutting down any balsam I could see. Downstream there were a few on the ledge outside Bridge House and a lot on the opposite bank but it only took a few minutes to slash them down as it's unlikely they'll regrow to produce seeds now.

Upstream there were a few isolated plants on the Glebe Land side and a couple of large clumps on the other side which I managed to clear.
