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.
