ADVICE (Tuesday 21 June 2022 until further notice)
Please be advised that we are aware of the increased presence of Azolla on
the River Nene. Azolla is similar in appearance to Floating Pennywort.
Azolla is an invasive plant species which, given the right conditions, can double
its wet weight in a week. Please do not attempt to remove the plant. We are
aware of its presence and will be monitoring the river accordingly.
