U.K. Mammals Trust says “Yankee animals, go home!”
From ANIMAL PEOPLE, September 2002:
LONDON–Great Britain from the time of Queen Elizabeth I
through the reign of Queen Victoria energetically exported favored
livestock and wildlife species throughout the British Empire.
Rabbits and foxes were sent to Australia and New Zealand,
starlings and house sparrows to the U.S.–but now Britain is on the
receiving end of introductions, especially from the U.S., and some
conservationists view the new arrivals as threats to the national
character.
David Macdonald and Fran Tatter-sall of the Mammals Trust
reported in May 2002 that the population of native English water
voles fell by 90% during the 20th century, due to habitat
competition and predation by introduced American mink.
Macdonald and Tattersall also blamed the recent decline of
native red squirrels on the success of introduced American grey
squirrels, and lamented that DNA analysis of native British pine
martens showed the presence of at least two American pine martens in
their gene pool.
