The Fen lies alongside the river Itchen and has chalk stream, fen and woodland habitats, but it is drying out. Tree and scrub growth have choked the fen causing great deterioration in water flow and light and led to a reduction in biodiversity. We hope to reverse this.
We have been removing some of the invasive areas of nettles and keeping the streams clear, whilst causing as little disturbance as possible.
As we move into summer we have seen tremendous vegetation growth - not all of it desirable! The nitrogen in the Fen and in the water that comes from the Itchen contributes to the growth of nettles, tussock grasses, and floating algae on the water surface. This is mainly outside our control, but scything of some of the areas later in the year may help to create spaces for the less vigorous wild flowers to grow. We have had lots of damselflies on the Fen and are hoping that later in the summer we will see more dragonflies too.
