The Maitland Files
A serialised interview with an international char
expert.
Q.
Arctic Charr are not listed under the new EU habitats directive.
Although as a species they are not threatened world wide, should
more vulnerable populations be protected?
A.
Yes! As just mentioned, because we are a stronghold for this species
in Europe we have a major duty to protect our populations of Arctic
Charr. Parallel examples of other animals range from the Freshwater
Pearl Mussel to the Otter, both of which, although they are still
quite common in Scotland, are given substantial protection through
the Habitats Directive. Thus many Special Areas of Conservation
are being created for them in Scotland - but unfortunately none
for Arctic Charr, which I believe is an equally deserving species.
Q.
Ireland and Scotland have a lot in common, not to mention the occurrence
of Arctic Charr. What do you see as the biggest threat to the survival
facing the species in Ireland and Scotland into the new millennium.
A.
Many of the previous threats which have destroyed our charr populations
remain, for example: acidification (Loch Grannoch), eutrophication
and water level changes (Loch Leven), overfishing (St Mary's Loch)
and fish introductions (Loch Heldale).
However,
two more recent threats give me greater concern for the future -
charr farming, which is likely to destroy the genetic integrity
of those stocks where escapes (or releases) of domesticated or foreign
stocks occur; and global warming, which may well eliminate our more
southerly and low altitude stocks, especially those in shallow lochs.
