To get the most out of your bioacoustic survey, the recorder needs to be placed in a suitable location. There are a few factors to consider when choosing a location for the device which are outlined below, along with the short video.
Our instructions include the following steps to get setup. Within your Carbon Rewild package, you should find the recorders, straps, and printed instructions for setup. The survey setup process has the following simple steps:
1. Survey Methodology
For a single recording device, you should place the recording device strategically, closest to the area you are planning to monitor.
If you are placing more than one recording device, then you have a choice about where to place the recording devices.
For an even distribution, you may wish to divide your site into a regular grid, spacing the recording devices evenly across the site. We recommend you space the recording devices no closer than 250m to avoid overlap of species recordings (some birds and bats can be heard at this distance).
The alternative approach is a strategic deployment, placing the devices near distinct habitats or areas of interest.
In reality, you are likely to combine these approaches for your survey design, and we can provide guidance based on your requirements. Please contact us if you would like to discuss your monitoring plan further.
2. What are you monitoring?
3. Avoid Vegetation
Vegetation and other objects can mask natural noises and reduce the chance of a successful species identification. Therefore, it is important to avoid a location which is surrounded by dense vegetation or attaching to large trees which can block noise.
It is especially important for bat monitoring to avoid vegetation and large surfaces nearby, as ultrasonic signals are more easily affected by these features, and can limit species identification.
Top tip: don’t just think about when you are deploying the recording devices, but think about the whole survey period. If you are deploying at the beginning of Spring, then vegetation will likely grow during the survey period, causing issues later on. You may also find yourself crawling through overgrown bramble to retrieve a device… we’ve been there!
If you have any questions about finding a suitable location, please speak to a member of the Carbon Rewild team, we are happy to offer guidance to help you maximise your survey.
