Presumed pine marten distributional range in Britain in 2018 as reported by Mathews et al. (2018) and 1915 (Langley & Yalden, 1977). Translocations took place in 2015–17 in region 1 (1. Mid-Wales) and in 2019–21 in region 2 (2. Forest of Dean, Gloucestershire). Regions 3–8 are regions considered in detail in this study (3. South West England, 4. Hampshire, 5. Southeast England, 6. East Anglia, 7. North Yorkshire, 8. South Cumbria). It should be noted that, as a consequence of the methods used, Mathews et al (2018) likely over-estimated the distributional range of pine martens in region 8 where the very few recent records provide no evidence of an established breeding population.
