This is a leech we found. (Sorry the picture is not very clear!)

Leeches are related to earthworms and lugworms (Oligochaetes), and bristle worms (Polychaetes). But unlike other worms they have a sucker at each end - one for feeding, the other for hanging on while they feed. They all belong to a group of legless invertebrates (animals without a skeleton) called Annelids - "anulus" is the Latin for "ring". This means that the body is divided into separate segments (which look like rings) connected by a continuous gut, a nerve and a blood vessel. They use external bristles (chaetae) to pull themselves along in a sort of concertina-like motion.

This old fallen tree took ages to remove as it had got well sunken in below the water line and had to be removed by chain sawing off the end bit by bit.

The River Lyd flows from Lydbrook in the north, through Cannop Ponds and on to Lydney. It is very pretty, quite fast flowing and contains fish.

 

Parkend - River Lyd

Grid Ref SO616076

 

This was a day for wellies and waders as we were to try and clear the River Lyd at Parkend from the debris which had washed down and blocked the river in many places. It is a difficult and dirty job and we all had to wash our hands with an alcoholic spray before tucking into our sandwiches at lunchtime as there is a danger of Weil's disease which is spread by rats. We also wore protective waterproof gloves so, hopefully, we should all be fine!

We cleared along the river for about a quarter of a mile but need to carry on with this site in the future as there were a further five debris dams to be seen.
