Brown Rat

Dark blue dots show records since 2000
Mid blue dots show records from 1990 - 2000
Light blue dots show records from before 1990
Rats are probably the least popular mammal in the country, and few people bother to record them.
Brown rats were eradicated from Ramsey Island in 2000, and have not been recorded there since. This has enabled some ground/burrow nesting birds to survive better there. Rats are not found on Skomer or Skokholm - one that was seen swimming ashore on Skomer in the 1950s was caught within 24 hours, and none have been seen since.
