Woodcock Survey results

Woodcock Survey Results

Results of the 2023 national survey

The 2023 survey revealed a UK population estimate of 51,687 males and a British population estimate of 50,750 males. The Northern Ireland population estimate was 937 males. The British population had declined by 8% since 2013, but by 35% since 2003. There were long-term declines in all survey regions apart from northern England.

We anticipated a general downward trend from our annual monitoring. However, the abrupt decline of 31.3% in Scotland since 2013 was quite unexpected, and more startling was the disconcerting 49.5% decline in northern Scotland since 2013. More encouragingly, Woodcock numbers had increased since 2013 in eight of the 11 British survey regions. Surprisingly, England and Wales had experienced population increases, of 19.4% and 24.5% respectively, during this period.

2023 national population estimates and comparative change, since 2003 and 2013

Region	2023 population estimate	Change 2003 to 2023	Change 2013 to 2023
England	28,940	-22.5 %	+19.4 %
Scotland	20,673	-47.3 %	-31.3 %
Wales	1,138	-35.6 %	+24.5 %
Northern Ireland	937	.	.
Britain	50,750	-35.2 %	-8.1 %

The overall rate of population decline slowed between 2013 and 2023 compared to between 2003 and 2013. However, the UK population overall had dropped by more than a third in just two decades and was continuing to fall despite some modest short term regional increases. The long-term decline remains a cause for concern, and especially that in northern Scotland. Scotland has historically supported the core of the breeding Woodcock population, so losses here will naturally have a greater impact on the overall UK population compared with other regions, cancelling out modest gains elsewhere.

This was the third large-scale survey of breeding Woodcock (2003, 2013, 2023) and was the biggest and most comprehensive yet. A total of 1,192 randomly selected 1-km survey squares was visited throughout the Britain in 2023. This represented an impressive 43% increase in sample size compared to 2013. Survey efforts in Northern Ireland resulted in data for 38 squares, allowing us to produce the first complete Woodcock population estimate for the entire UK.

Future work

The cause of the ongoing UK population decline and the sharp reduction in northern Scotland since 2013 is not clear. There are likely to be several contributing factors, potentially involving nesting habitat suitability and availability, breeding productivity and winter mortality. We will continue short-term monitoring via our annual surveys, which will provide early warning of any further changes. The 2023 survey results will be key for informing the current review of national conservation policies and actions required to secure the future of this species in the UK.

Annual roding counts: 2003–23

Thanks to a growing group of dedicated volunteers, we have good data on the number of roding Woodcock for up to 200 sites since 2003.

Generally numbers have declined at the monitored sites over the past two decades.  However there are substantial changes between years reflecting variation in  survival and breeding productivity.
