To take part in the British Bat Survey or Jersey Bat Survey please follow the steps below.
Bat monitoring activities are currently restricted in order to comply with government guidance on controlling the COVID-19 pandemic. Please ensure you adhere to the latest government instructions at all times. Government instructions vary across the UK so it is important that you refer to the guidance specific to the country you live in.
How we use your data
British Bat Survey: In line with the National Bat Monitoring Programme's data access policy, bat records collected by the British Bat Survey will be made available on the NBN Atlas at 1km resolution.
Step 1. Identify a suitable survey point
When you sign up to the survey you will be provided with an approximate monitoring location. Visit this location during the day to identify a suitable point to deploy your AudioMoth. Your survey point should be:
- Safe to access.
- Secure enough to leave an AudioMoth overnight.
- Not lit be artificial light at night.
- At least 1.5m away from:
- Vegetation or other obstructions that could mask bat calls.
- Hard surfaces such as tree trunks or walls, which can cause echos that distort recordings.
- Water - the reflections of sound off the water's surface can distort recordings.
If your survey point is on private or council-owned land please get permission from the landowner to carry out the survey. Click here for tips on getting landowner permission. Bear in mind that you may wish to survey the location on multiple nights.
Step 2. Receive your survey kit
Jersey Bat Survey: We will provide a survey kit containing an AudioMoth, a weatherproof case, memory card(s), batteries and poles.
British Bat Survey: We will provide a survey kit containing an AudioMoth, a weatherproof case and memory card(s). You will need to purchase a two metre pole and three AA batteries. The AudioMoth should be deployed on a pole 2m above the ground. Due to their bulky nature we are unable to supply poles in the post. The following make an ideal pole, secured if necessary with a few guy ropes, and can be purchased for a few pounds online or from many high street shops, DIY stores or garden centres:
- Extendable/telescopic laundry/clothes prop (https://images.app.goo.gl/VZWt...)
- Sturdy bamboo cane (at least 2m high, approximately 5cm in diameter at base and no less than 2cm diameter at height).
- Steel garden stake or bean pole
- Ranging pole/rod (https://images.app.goo.gl/2dkm...)
Due to EU shipping regulations we are unable to send batteries in the post. As a result of the high power demand of ultrasonic recording we recommend Energizer Ultimate Lithium AA. Please do not use rechargeable batteries as they will cause the AudioMoth to fail.
Step 3. Set up your AudioMoth
Your AudioMoth is configured very simply by pressing the 'Play Chime' button on this webpage. This chime tells the AudioMoth when to start recording, when to stop recording and what recording settings to use. Click here to configure your AudioMoth.
Step 4. Carry out a survey
Carry out your survey between 1st and 31st July.

Step 6. Return your memory card(s)
Jersey Bat Survey: Please return your memory cards and equipment to the Government of Jersey’s Natural Environment Team at the end of your survey.
British Bat Survey: Return your memory card to BCT as soon as possible after your survey - Remove the memory card from the AudioMoth and place the card into its plastic adapter. Place the adapter into one of the FREEPOST envelopes provided and write your survey point name on the back of the envelope. Without your survey point name we will be unable to process you recordings. Post back to BCT as soon as possible, you do not need to wait to return the rest of your equipment. We will analyse your recordings to identify the bats you have detected. Please keep a copy of your recordings if you would like to retain them. We will contact you later in the year to arrange the return of your survey kit.
Step 7. Getting your results
At the end of the survey we will email you a list of all the bat passes and species that you have detected at your survey point.
