Key Survey Information
View a summary of the key survey information in the Wader Calendar Infographic.
The Wader Calendar is a quick and easy way for farmers to record waders on their farm and contribute to a national monitoring scheme.
We want to enable farmers to monitor waders on their land to collect evidence that can be used to evaluate and improve the effectiveness of conservation management.
There is no strict survey methodology - just weekly estimates of five target waders on your farm April to July. The time it takes depends on your methods, keeping notes as you go should only take a few minutes each week, but dedicated counts at set times in the week may take longer. You only need to be able to recognise and identify the five target species: Curlew, Lapwing, Oystercatcher, Redshank and Snipe.
We hope this method will allow farmers to contribute to the available information on waders for their farms. Farmers and waders in the UK have both been impacted by the sweeping changes to farming landscapes and practices over the last century. Farmers are the traditional custodians of waders and increasing their involvement in wader monitoring and conservation will improve the outlook for waders in the UK.

Uk waders are in decline. BTO science seeks to deliver the impartial evidence required to develop and support realistic conservation strategies for these species.
What's next for our waders?
Recent BTO work focuses on understanding the variation in Curlew and other UK wader populations so that we can help suggest actions to conserve them.
