Bat Surveys in Cambridgeshire and London

Greenwillows Associates undertake bat surveys across Cambridgeshire, Bedfordshire, Norfolk, London and nationally.

From the head office window, our pleasant view is changing as the blackthorn is superseded by hawthorn blossom and the cowslips and bluebells come into their own.
Our first botanical training day is coming up on the 29th May. Working with consultant botanist Jonathan Graham, participants will spend a day learning how to identify flowering plants on the southern border of the Fens.  We still have a couple of places left, so get in touch if you’d like to join us! Head to our training and recruitment page to find out more.

As the bat survey season proper really takes hold, our sonogram analyst Claire, has been running a series of refresher toolbox talks on bat surveying technique. Working with groups of fieldworkers in Cambridgeshire and London, Claire talked through the processes and methods of using the Petterson bat detector and Edirol recorder to enable accurate and efficient analysis of bat calls.  These workshops were fun, informative and enabled fieldworkers to flag up any queries they had about bat surveys in general. These workshops effect a cost-saving for the client as Claire’s time is used very efficiently during the analysis process. Using Echocollate™ software for the remote static bat recording devices (Song Meter 2), further streamlines the analysis once back in the office.

With the newt survey season well under way one of our ecologists, Emma found this palmate newt Lissotriton helveticus whilst out on a survey in Essex.


Palmates are Britain’s smallest amphibian and have a more limited range than smooth or great crested newts as they tend to prefer shallow ponds on acid-rich soils, limiting the locations where they can thrive. Whilst on the IUCN Red List, palmates have a status of being classified as ‘least concern’.  Having said this, along with other British amphibians palmates have been in serious decline, and it is uncommon for us to spot palmates whilst on out on a survey.
