Last week 47 students from Brighton University descended on the river as part of their field studies course. Being taught survey techniques and identification skills they undertook electro-fishing, kick sampling and hab scoring across 3 stretches of the river. As well as enjoying splashing around in the river, the trip helped us collect invaluable data for the project which will be used as our pre-restoration monitoring.
Although the final results are yet to come in here are a few species that we found:
Various types of mayfly larvae including burrowing and non-burrowing species
Cased and caseless caddis
Various midge larvae
To help with our monitoring we will also be continuing with our invertebrate traps throughout winter. If you’re keen to get involved just get in touch. No previous experience is necessary.
With the seasons changing and the sun shining it can mean only one thing; it’s wildlife survey time! We have now set up a dragonfly and damselfly survey down on the flood meadow. Local expert John Luck came along to help out not only with the set up of the walk but also by training the volunteers so they knew what to look out for.
The second transect took place mid- June and what more could you ask for than beautiful sunshine whilst walking along the river in gorgeous surroundings? The conditions were perfect, and there was plenty to see. The river is quite fast flowing here, limiting the number of different species we would expect to see, as only Demoiselles are fond of fast flowing water. However, all of the species we did see were in quite good numbers.
Banded Demoiselles – 28 males and 8 females
Beautiful Demoiselles – 2 males and 2 females
Small Red Damselfly – 4 males and 1 females
Red eyed Damselfly – 1 male
Whilst carrying out the transect we not only saw damselflies but were lucky enough to catch a glimpse of a Kingfisher, and also spotted a Hobby which was a first! All in all it was a very successful day.

Towards the end of December 2013 the River Ouse over spilled into the flood plain at Sheffield Park. This was a sign of things to come as the whole meadow was eventually under water during the Christmas storms a matter of weeks later. However, at this point in time the flooding was minimal and simply gave us a chance to see what the meadow would look like if the meanders were reinstated.
It was a beautiful frosty morning with the meadow initially covered in mist. During our trip down there the mists cleared and the sun came out showing that it is a picturesque place to be even in winter.
On 14th August 2013 one of our volunteers, John Luck, undertook a further dragonfly survey on the flood meadow. This is an annual survey, which charts the progress of different species and logs the difference in numbers from one year to the next.
“The group was particularly keen that I should visit the river stretch again this year, which I did. This produced the expected Banded demoiselles (in good numbers) plus a few Beautiful demoiselles, also a Migrant hawker. The river is quite fast flowing along this stretch so I cannot imagine reopening the meanders will do anything but good for Odonata.”
On 6th June 2013 members of the Engagement group from the Adur–Ouse Catchment met at Sheffield Park to look at the project, enjoying a walk in the sunshine. We got a flavour of the great things to come for our visitors and the day was made even better by fleeting glimpses of a kingfisher.
We discussed ways in which river restoration can enhance both landscape and visitor experience, and ended the afternoon with tea and cake in the Coach House Tearoom.

The sun shone and we saw dragonflies (Common darter) despite it being November – the original aim was to look at habitat management so the sighting was a real bonus. A walk to the site stimulated much debate. Comments from group included:
“Many thanks for a very informative and enjoyable morning. The site promises to be a fantastic resource. We’re very glad we live nearby!”
“Could consideration be given to the deposition of gravel to allow breeding by sea trout? This is what the Ouse and Adur River Trust have been doing elsewhere with some success.”
“My children & I all enjoyed the presentations and I was very interested in the proposals for reintroducing 2 of the 3 meanders in the meadow …. I support the plan to reintroduce the meanders and look forward to helping to monitor the resulting changes in flora within the meadow.”
