THAMES ROAD WETLAND HITS 20 SPECIES OF ODONATAThames Road Wetland, managed by Thames21 volunteers, has seen an increase of 6 species of Odonata in the last 12 months, adding a couple of the newer arrivals in the UK that have been present at other sites in the Borough for a while now and two undergoing general range expansion. This is likely to be due to increased observer effort, with a helper who lives fairly close now visiting the site 2 or 3 times a week.
Autumn 2025 saw the addition of Scarce Chaser.
A Four-spotted Chaser was photographed on 5th June 2026, a Norfolk Hawker on 1st July, a pair of copulating Southern Migrant Hawkers on July 22nd and a Southern Hawker on 21st August.
A Lesser Emperor was also seen.
Although only 2ha in area, the site benefits from a large expanse of floodplain land to the south and west, and the Outer Crayford Marshes and Dartford Marshes stretching down to the Thames to the north of Thames Road.
The full list of species is currently:
Damselflies (6) - Azure, Banded Demoiselle, Blue-tailed, Common Blue, Large Red, Willow Emerald.
Dragonflies (14) - Hairy, Brown Hawker, Migrant Hawker, Norfolk (Green-eyed) Hawker, Southern Hawker, Southern Migrant Hawker, Emperor, Lesser Emperor, Broad-bodied Chaser, Four-spotted Chaser, Scarce Chaser, Black-tailed Skimmer, Common Darter, Ruddy Darter.
Thanks to Jim and Tom for photos.

JOIN A WETLAND HABITAT WORK SESSION AT CRAYFORD MARSHES ......The next Thames21 staff-supported event at Thames Road Wetland, an important wildlife site on the Inner Crayford Marshes, will be on Friday 11th September.
We will be clearing cut Reed to retain open pools, digging out Reed rootmat to 'recover' open water areas for Dragonflies and Water Voles and clearing out more of the road run-off trap so that it has plenty of capacity once the autumn rains kick in.
Samantha Dhedhi will be bringing all equipment provided. No sophisticated skills needed. A chance to meet new people and get close to wildlife.
Basic refreshments available. Loos available at the nearby council depot.
