Thirty British species near extinction
From ANIMAL PEOPLE, July 1996:
LONDON––The South West
Regional Biodiversity Audit, the first
attempt to monitor the status of wildlife over
an entire region of England, reports after
four years of research that at least 30 species
are near extinction and as many as 7,000 are
“of conservation concern.”
At most risk, the audit found, are
the white-clawed crayfish, the harbor porpoise,
aquatic warblers, and southern damselflies,
followed by river otters and large
blue butterflies. Both have been subject of
recent reintroductions, the large blue butterflies
after having once been believed to be
extinct. The most controversial recommended
protection measures may involve
closing five Devon river basins to crayfish
farming, to protect the white-clawed crayfish
from introduced competitors.
