Each year of the project we are holding a series of invertebrate workshops on identification, recording, curation of reference collections and field craft to help boost the skills of beginners and experienced entomologists alike. We are also organising invertebrate recording days across the region to bring together the invertebrate recording community and facilitate improvements to baseline data coverage at selected important sites. Results will be published on this website. Other events include drop-in sessions to facilitate networking and mentoring.

Hale Duck Decoy Invertebrate Recording Day

3rd July | 1:30 pm - 5:00 pm


An afternoon invertebrate recording session at Hale Duck Decoy, Nr Widnes. This is a joint event with Lancashire and Cheshire Entomological Society.

Hale Duck Decoy is a small reserve within the Mersey Estuary SSSI, owned by the Fleetwood-Hesketh Estate and managed by Halton Borough Council. It covers an area of 3 hectares of Hale Marsh, on the north bank of the River Mersey. The reserve is in the shape of an irregular pentagon, surrounded by a 16 foot wide moat and a continuous clay bank. The centre of the reserve is occupied by the Decoy pond, which has five arms radiating outwards to each corner of the pentagon. Between the arms (which are known as pipes) are five small areas of woodland.

According to RECORD, 105 invertebrate species (excl. leps) have been recorded within the same 1 km as the decoy. Most of these are flies and spiders from recording in 1999 and almost all recent records are of dragonflies, except for some other groups recorded by Tony Hunter and Gary Hedges during an August 2018 visit. The site has much potential for further survey.
