Wild Otter Spraint Survey Methods

Otter spraint surveys provide a reliable, non-invasive method for monitoring otter populations that informs conservation management supporting otter welfare.

Key Facts

Spraints are otter droppings deposited at prominent waterside locations as territorial markers
Standardised survey methods provide comparable data on otter presence and activity
DNA analysis of spraints enables individual identification without capture
Spraint surveys are conducted at low water level for maximum detection efficiency
UK-wide surveys have documented otter recovery across most major river catchments

Welfare Considerations

Non-invasive population monitoring through spraint surveys supports otter welfare by identifying threats including road mortality hotspots and habitat deterioration without disturbing individual animals. Population data informs conservation management that protects individual otter welfare at landscape scale.
