But it survived in Scotland’s cleanest bodies of water in the north and west. Today, the species is flourishing across Scotland, and recovering well across the UK as waterways are cleaned up.

The rapid contraction of the otter’s range in the twentieth century precipitated the first otter survey of Scotland in There have been four subsequent surveys in Scotland to monitor otter distribution. The otter survey of Scotland (Green & Green, ) 2. The otter survey of Scotland (Green & Green, ) 3.

Otters are highly charismatic and popular animals of very considerable concern to conservationists worldwide. Written by the pre-eminent authority in the field, this book builds on the reputation of the author's landmark monograph of the European otter, Wild Otters (OUP, ).

Furthermore, its broader scope to include all species of otter in North America as well as Europe and. The National Otter Survey of Scotland - (Green and Green) was also used as a reference.

Survey Methods Field Survey The survey area was defined with regard to specified standards (DMRB Volume 10 ) and was agreed with SNH.

The survey boundary extended m either side of the centreline of the proposed scheme alignment. The number of people visiting the Otter Pool has increased tenfold since it was established, now attracting more t visitors per year.

This makes it one of the most popular attractions in South West Scotland. Facilities at the site had struggled to cope with this high level of popularity. Biological Conservation 36 () TØ Otter Lutra lutra in Albania Claudio Prigioni, Giuseppe Bogliani & Francesco Barbieri Dipartimento di Biologia Animale, Università di Pavia, Piazza Botta 9, Pavia, Italy ABSTRACT During a survey in Albania we found signs of otters at 17 (%) of the 31 stations investigated.

references to published sources of guidance on survey methods are listed in Section 5. A training log book with example entries is provided in Section 7. Status Eurasian otter populations throughout Western Europe declined over the 20th century, with the decline in the UK.

Abstract. Systematic searches for marten feces or’ scats’ have been used since for assessing the status of protected populations of pine martens (Martes martes) in us surveys using scats have relied on unsubstantiated assumptions that martens typically defecate along roads and trails, that martens inhabit primarily woodland habitats, and that scats from martens can.

Organochlorine pesticide residues and PCBs were measured in otter (Lutra lutra) scat samples from 94 sites in the River Clyde catchment, its estuary and neighboring coastal waters in western Scotland. Contents of pesticide residues were generally low.

PCB amounts were high in some regions in the study area (geometric mean contents up to mg kg−1 lipid). obtained from the National survey of otter distribution in Scotland (Strachan, ). Reference was made to the research paper Ecology and Conservation of Otters in Loch Lomond and the Trossachs National Park (McCafferty, ).

Boat Survey The field surveys consisted of two stages, stage one involved a boat based survey. The European otter has been here for millions of years; it is a member of the Mustelid family, which also includes the badger, mink, weasels, stoats, martens and polecats, and is the only truly semi-aquatic member of the weasel family.

The average otter is 1– metres in length, and weighs up to 9kg. England Otter Survey Database As part of a scheme to monitor the distribution of otters throughout the UK, four England otter survey have been carried out covering the years.

Tell-tale signs that otters live in an area include small piles of otter spraint around the coast. This nutrient-rich dung can have a strong smell when fresh; it is then dark and slimy-looking but you are more likely to see it dried out to resemble a pile of tiny fish bones and shell often on a tuft or mound of brighter green grass fertilised by the spraint.

Data on a small sample of mink faeces are also included. MATERIALS AND METHODS Samples of otter faeces from Scottish rivers were collected during the Scottish otter survey of (Green and Green, ).
