North Somerset is a local bat ‘hotspot’ but is also internationally important for one species - the Greater Horseshoe Bat.


Eighteen species of bat can be found in the UK of which 13 have been recorded in the parishes of Yatton and Congresbury. Other species may be added as a result of YACWAG’s survey work.


The local landscape supports two Greater Horseshoe maternity colonies whose roosts form part of the North Somerset and Mendip Bats Special Area of Conservation (SAC).

Wildlife > Bats

The YACWAG Batmap project aims to find out where our local bats roost, feed and fly. Members are encouraged to help with bat recording, surveying and the interpretation of results. Training and equipment is provided. 


The project received a Community Wildlife grant from Big Lottery Awards for All enabling the purchase of radio tracking equipment, Anabat recorders as well as maternity and hibernation roost bat boxes.

Bat helpline

Bats are fully protected in UK law. They are harmless and need our protection.


If you find a bat, which may be sick or injured, please visit the Bat Conservation Trust website or ring their helpline 0345 1300 228.


In the UK bat droppings and urine contain no viruses, bacteria or fungi. If you have bats in your house, church or other building and would like to know more, you will find advice on the Bat Conservation Trust website, or please get in touch through our Contact Us page.

About Bats

Bats are mammals with super-skills like echo-location, enabling them to zoom around at high speed in the dark. Their mysterious abilities have led to their reputation as scary creatures and there are many myths around bats which are completely untrue. There are no vampire bats in the UK – all of our native species feed on insects, so the more bats flying over your garden the less trouble you will have with midges. One bat can eat as many as 2000 in a night!


Little was known about bats until modern technology came along.  New equipment that converts the high-frequency sounds of bat calls into sounds that human ears can hear, gives certainty to which species are calling or feeding.

Our local bats

There are 18 species of bats in the UK, 17 of which breed here. The Yatton and Congresbury area is a bat hot-spot with 13 species to be found – 12 of which have been found in our Littlewood reserve. The internationally rare Greater Horseshoe bat is one of the highlights locally as the bats have an important maternity roost nearby in Brockley.


Our Local Bats:


     1.     Greater Horseshoe

     2.     Lesser Horseshoe

     3.     Serotine

     4.     Noctule

     5.     Daubentons

     6.     Natterers

     7.     Whiskered

     8.     Brandts

     9.     Common pipistrelle

     10. Soprano pipistrelle

     11. Nathusius pipistrelle

     12. Brown long-eared

     13. Leisler (historic record – no recent local record confirmed)



The discovery of Barbastelle bat and Bechsteins bat, both woodland specialists, in Kings Wood remains a distinct possibility. The Grey Long-eared bat has also been found in North Somerset but not locally at present. A ‘new’ species, the Alcathoe bat, was confirmed in the UK in 2009 and its presence in North Somerset may be a matter of time.


YACWAG manages its reserves to produce insects needed by bats, creating places for shelter. We have put up bat boxes so we can monitor bats and cleared, restored and created water-courses on our reserves. We also aim to encourage bigger, denser hedges to give shelter from the wind and predators. Hedges and trees also produce insects for food.


YACWAG monitors local planning applications. Many bat roosts and habitats have been lost to housing development within our area but we now comment on most damaging planning applications and raise awareness of the needs of bats. We also notify roosts and habitats and have put up hibernation boxes.

Our significant Bat monitoring milestones

2003

Littlewood, a small (2 ha) woodland was purchased. It was considered important for bat foraging and commuting across Kenn Moor SSSI. The £20,000 project was funded through three grants.


2004

Bat and invertebrate monitoring project for Littlewood. £2500 was raised fgrom a grant for bat detectors and moth trapping equipment. Local training courses for bat and moth identification were run in conjunction with Goblin Combe Environment Centre. As well as training in the use of detectors and Batscan computer analysis.


2005

National Bat Monitoring Programme (NBMP) Waterway survey started, Congresbury Yeo


2006

NBMP Field survey started, Claverham. Avon Bat Group Batscapes Project established Parish Bat Warden scheme. Littlewood bat box monitoring project established in conjunction with Avon Wildlife Trust (AWT) North Somerset Levels and Moors officer (35 bat boxes placed in YACWAG’s reserves).


2009

One Nathuius pipistrelle bat discovered at Blagdon Lake as part of NBMP survey


2010

Batmap project established with £4000 grant for Anabat recorders. Static recorders placed on YACWAG reserves including Littlewood.


2011

Batmap project extended through £5,700 Big Lottery Fund Community Wildlife Grant, providing radio tracking equipment and tags. Serotine and Nathusius bats tracked with ground-breaking results.


2012

Remarkable total of 12 bat species recorded using Littlewood for foraging and roosting including Greater Horseshoe Bat. YACWAG’s key volunteer, Daniel Hargreaves, awarded Bat Conservation Trust’ Pete Guest Award.


2013

Nathusius pipistrelle bat tagged at Blagdon Lake in 2012 found in Netherlands in December 2013. This made national press and TV news.


2014

YACWAG hosted a National Nathusius Conference at Ubley.


2015

A Natterers roost in a bat box was discovered in Littlewood. Two YACWAG volunteers completed training and obtained Class 2 licences from Natural England for checking bat roosts.


2016

Grant received from Bristol Airport for purchase of user-friendly bat detectors for surveying activity of Greater Horseshoe bats in and around Cleeve and Wrington.


2017

The Co-op food store in Yatton helped raise funds to buy more ‘entry-level’ bat detectors so that school groups, Brownies, Cubs and other children can have access to a bat detector on walks, giving them a close-to-nature experience.
