Analysis of long-term effort-related land-based observations to identify whether coastal areas of harbour porpoise and bottlenose dolphin have persistent high occurrence and abundance (revised June 2015) 2015

Abstract

Since 1965, dedicated shore watches for cetaceans have been conducted at a number of sites around the UK. Over 75,000 hours of watches and around 50,000 associated sightings of bottlenose dolphin and harbour porpoise from 678 sites around the coasts of Britain have been analysed. This analysis is aimed at determining whether areas of persistent high occurrence and relative abundance of the two species can be identified.

This is a revised version, incorporating a number of minor amendments, and supersedes the previous version of JNCC Report No. 543, published in March 2015.
