An evaluation of the effectiveness of great crested newt mitigation projects in England, 1990 – 2001 (ENRR575)

An analysis of great crested newt Triturus cristatus mitigation projects carried out between 1990 and 2001 was performed by (1) reviewing all licences issued by English Nature and Defra over this period; and (2) a questionnaire survey of a large sample of mitigation projects. A total of 649 licence files covering some 345 mitigation projects were examined from English Nature files. Over half of these contained no report of work undertaken under the licence. A total of 153 questionnaires were distributed, yielding information on 72 mitigation projects.
