Dwyryd Otter Survey

How many otters are there on the Dwyryd? Whereabouts are they? What is the ratio of males to females? To help build on existing knowledge and gain a fuller picture there will be a weekend survey between 17th to 19th May organised by Ceri Morris through the MISE project - Mammals In a Sustainable Environment.

In addition to the weekend survey, which hopefully will involve at least twenty people, there is a requirement for local volunteers to 'spot check' key sites over the course of one year. All you need to be able to do is identify and collect otter spraints (poo), put them in a bag, freeze them and send to Ireland (Waterford Institute of Technology) for DNA analysis.

This builds on the work that the Dwyryd Otter Partnership and subsequently Snowdonia Mammal Group undertook a few years ago. An analysis of spraints showed amongst other things that otters feasting on seafood could travel all the way to Trawsfynydd before having to poo.

If you would like to take part please contact Ceri Morris by email at: c.morris@ccw.gov.uk

Meanwhile here’s a film clip of some Dwyryd otters in 2011.
