Estimating Otter Numbers Using Spraints: Is It Possible?

Estimating Otter Numbers Using Spraints: Is It Possible?

Spraints have been used to survey otters in the UK since 1979 and a standard methodology has been set up which has been used in Britain and Europe for most survey work. At present data from these surveys is being used to give an estimation of actual population numbers. However, for this to be possi...
