Cased caddisfly nymphs

Our Riverfly Monitors are pleased to share these short videos of Caddis and Mayfly nymphs.

These cased Caddisfly (Limnephilidae) were netted during riverfly sampling in the River Wye at Kingsmead near High Wycombe in January 2022. This family may build their cases from sand or sticks in the river.

These mayfly were caught during a river fly count in Backstream (a tributary of the R. Wye) at Beech Road ford near High Wycombe in February 2022. They are one of the largest mayfly, inhabiting the sediment in flowing rivers, and are an attractive food for fish. Note the feather-like gills which is characteristic of this family. They remain as nymphs for at least 1 year.

A resident, who lives across the river from High Wycombe Lawn Tennis Club contacted us recently, via our website, expressing concern that the overgrown vegetation on the banks of the club was trapping debris in the river and affecting the brown trout spawning areas that she knew were there.

The club groundsman had started cutting down vegetation but needed advice from us, and didn’t have the necessary tools or waders to do the work.

We went out and checked the river bank and access points, and agreed that two of our experienced river work volunteers would do the necessary vegetation clearing from the river wearing waders. They had a session last week and made good progress, which can be seen from the photos.

There will probably be another session, but we have already received the following from the neighbour who was concerned:

‘I am really impressed with the difference. The river is looking so much better – thank you. There was a little egret happily ‘shuffling’ in the newly cleared area shortly after you left. Hopefully the brown trout will return to spawn in November.’

Following a request from Buckinghamshire Council, Friends of the Wye River Wye Conservation Volunteers worked hard to clear in-stream vegetation to reveal the river and speed its flow.

Thanks to volunteers Bill and Ed who made a huge difference as can be seen in the ‘before’ and ‘after’ images.

Bill & Ed conserving the Hughenden Stream

We’ve now had three work parties at Hughenden Park during October, November and December.  One of our volunteers, Bill Smith, has created a video showing the stream in various stages of our improvements, and has included some of the photos of our River Wye Conservation Volunteers taken by Keith Sonley on the actual days. You can certainly see the difference we’ve made.

Judy and Keith led an intrepid team of 11 volunteers continuing to clear excess vegetation in the Hughenden Stream.

Clearance in progress

Despite a full-on downpour as the team waited to start work, and heavy rain showers during the morning, spirits were not dampened and no one complained.

Just ‘drinking in the rain’

The final indignity was heavy rain while a rest was taken for tea and coffee – chocolate biscuits helped though!

The difference made is clearly visible, with the stream now flowing much faster.

The thick of it
Done!

Our thanks go to leaders Judy & Keith, and volunteers Bill, Dave, Eddie, Graham, Jane, Jean, Joy, Julie, Mike, Steve & Terry.
