The Friends of Poets’ Walk are taking part in The UK Butterfly Monitoring Scheme using a fixed-route walk (transect) over Church Hill and Wain’s Hill drawn up and registered on-line in 2016 by our butterfly representative Bill Thompson.
Latest news Autumn 2019 – The national butterfly recording season closed at the end of September and Bill reports that butterfly numbers were up this year with a total of 1,990 butterflies compared with 1,754 last year and 1,323 in 2017.
He writes: It has been a spectacular year for the butterfly numbers on our transect. We can clearly see that the good weather in the early part of the year influenced the numbers and also perhaps the re-appearance of some species. We can definitely see a pattern emerging on our transect that reflects not only the weather but the emergence of two broods during the year.
The big winners this year were Gatekeeper, Common Blue, Marbled White and Ringlet with the big success story being the inter-continental migrant, Painted Lady.

To take part in the scheme a transect must be established at a chosen site and butterflies are recorded along the route on a regular (weekly) basis under reasonable weather conditions for a number of years. A transect route is divided into sections, which are chosen to represent the various habitat types and management activities across the site. It must remain unchanged to enable butterfly sightings to be compared from year to year.
Butterflies are recorded from the beginning of April until the end of September. Certain requirements apply relating to time of day and weather conditions. Data is recorded and summarized results submitted to the UK Butterfly Monitoring Scheme (UKBMS).
Our Church Hill and Wain’s Hill transect is divided into nine sections starting at the path (Hack’s Way) on Old Church Road and ending on the coastal path. Its total length is about 2.6 km (1.6 miles) and the walk takes around one hour.
