Butterfly Survey

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 last year (2016) by our butterfly representative Bill Thompson.

Our latest butterfly news – October 2017: Clouded Yellow on Poet's Walk summer 2017

Butterfly survey leader, Bill Thompson, summarises butterfly sightings in 2017:

“This year we recorded a total of 1,323 butterflies as compared with 639 last year, with the highlight being the Clouded Yellow spotted by Sue Batchelor in Week 19. There were also two Silver Washed Fritillary seen during the year and it was pleasing to see the Small Copper, Comma, Red Admiral and Common Blue all make good showings.”  Read the full summary …

Poets Walk Butterflies Transect map

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.
